This software was originally derived from software contributed to the University of California, Berkeley by Steve Kirkendall, the author of the vi clone elvis. Without his work, this work would have been far more difficult. IEEE POSIX 1003.2 style regular expression support is courtesy of Henry Spencer, for which I am *very* grateful. Elan Amir did the original 4BSD curses work that made it possible to support a full-screen editor using curses. George Neville-Neil added the Tcl interpreter, and the initial interpreter design was his. Sven Verdoolaege added the Perl interpreter. Rob Mayoff provided the original Cscope support. o Many, many people suggested enhancements, and provided bug reports and testing, far too many to individually thank. o From the original vi acknowledgements, by William Joy and Mark Horton: Bruce Englar encouraged the early development of this display editor. Peter Kessler helped bring sanity to version 2's command layout. Bill Joy wrote versions 1 and 2.0 through 2.7, and created the framework that users see in the present editor. Mark Horton added macros and other features and made the editor work on a large number of terminals and Unix systems. o And... The financial support of UUNET Communications Services is gratefully acknowledged. nvi-1.81.6/README.1st0100644000076400001440000000072210720065506013041 0ustar skimousersThis is a development version of nvi.

Note that there is a small problem with DB 3.2 in that it will not let nvi read in a final line that doesn't end in a newline. This should be fixed in DB 3.3 If your system library (such as glibc prior to version 2.2) uses a previous version of db (e.g. DB2) internally, you must configure with --enable-dynamic-loading to avoid symbols in the internally used db from being resolved against the newer db. If, on top of that, the vi binary is explicitly linked against that previous version of db (such as might happen if you enable the perl embedding), you should compile the 3.x version with all symbols internally resolved. In case you use the Gnu linker (ld), this can be accomplished by passing it the -Bsymbolic option. You can do this by setting CC to e.g. "gcc -Wl,-Bsymbolic" prior to configuring db. See docs/ref/build_unix/flags.html in the db distribution for more information. skimo@kotnet.org nvi-1.81.6/TODO0100644000076400001440000001141510720065506012144 0ustar skimousers# $Id: TODO,v 8.2 1997/04/12 15:53:31 bostic Exp $ (Berkeley) $Date: 1997/04/12 15:53:31 $ ======================================================================== GENERAL ======================================================================== 2.0: Open mode is not yet implemented. ======================================================================== DB ======================================================================== 1.N When nvi edits files that don't have trailing newlines, it appends one, regardless. This is required, by default, from POSIX.2. 1.N: If you run out of space in the recovery directory, the recovery file is left in place. 2.0: It's known that it's possible to sync the backing files in the wrong manner, leaving backup files that aren't recoverable. This is going to be left alone until we have a logging version of DB, which will hopefully fix this (or at least make it possible to easily do so). ======================================================================== VI ======================================================================== 1.N: Make the search pattern and command history (what the '.' command executes) remembered between windows, or configurable so that it is. 1.N: Change the screen scrolling to not eat user characters... i.e. g/pattern/foo should not eat already entered chars. 1.N: The vi main command loop should use the general-purpose overflow and underflow routines. In addition, the vi command loop uses unsigned longs -- should probably be fixed as a 32-bit unsigned type, and then check to make sure it's never used as as variable type again. 1.N: Should "view" set a lock on the file? 1.N: Should "view" copy the file (or even open a recovery file)? 1.N: The strings found by searches should be highlighted until the next character is entered. 1.N: Display a split vi screen for the :help command. 1.N: When getting a key for a continue screen, we should always read from the terminal, not from a mapped key. 1.N: The sentence, paragraph and section movement commands don't match historic practice in some boundary cases. This should be left alone until POSIX 1003.2 makes up its mind. 1.N: The vs_sm_fill routine should scroll if possible, not always redraw. 1.N: Think about setting a dirty/inuse bits on the lines of the SMAP structure. That way the message routines could steal lines and refresh would continue to work, because it would know not to touch the lines that were in use. ======================================================================== EX ======================================================================== 2.0: ^C isn't passed to the shell in the script windows as an interrupt character. 2.0: It would be nice to inverse video the replaced text during interactive substitute. 2.0: The :args command should put the current file name out in reverse video. This isn't going to be easy, currently only full lines can be in reverse video, not just parts. ======================================================================== CURSES ======================================================================== 1.N In single-line screens, have to press 'q' twice when quitting out of a ":set all" display. ======================================================================== MOTIF/IPC ======================================================================== 1.N: We currently permit the user to change the lines, columns and term edit options. Shouldn't that be illegal in a window interface? ======================================================================== REDESIGN ======================================================================== 2.0: There's a serious problem with error returns -- we need to separate command failure from fatal error, consistently, over the entire source tree. We need to rework all of vi to have three return values: 0: success 1: vi error, continue 2: fatal error, die Right now we don't recognize fatal errors for what they are. 2.0: The complete list of POSIX.1 calls that can return EINTR are: wait, waitpid, sleep, dup2, close, read, write, fcntl(SETLCKW) tcsetattr, tcdrain The problem is that technically, any system/library call can return EINTR, so, while nvi blocks (most of?) the obvious ones, someone may have to do a complete pass and block signals everywhere. 2.0: The options hardtabs, lisp, optimize, redraw, and slowopen are recognized, but not implemented. 2.0: Field editing shouldn't be hard to add to nvi: Field editing file template: version # field # row/column start row/column stop label field # Label string re field # Matching re string. field # row/column start row/column stop label field # Label string re field # Matching re string. moves to the next field in column 0 moves to the previous field nvi-1.81.6/build.unix/0040755000076400001440000000000010720065506013536 5ustar skimousersnvi-1.81.6/build.unix/README0100644000076400001440000003061210720065506014415 0ustar skimousers# $Id: README,v 8.29 2001/05/13 20:52:36 skimo Exp $ (Berkeley) $Date: 2001/05/13 20:52:36 $ Nvi uses the GNU autoconf program for configuration and compilation. You should enter: ../dist/configure make and nvi will configure the system and build one or two binaries: nvi and tknvi. You can use any path to the configure script, e.g., to build for an x86 architecture, I suggest that you do: mkdir build.x86 cd build.x86 ../dist/configure make There are options that you can specify to the configure command. See the next section for a description of these options. If you want to rebuild or reconfigure nvi, for example, because you change your mind as to the curses library that you want to use, create a new directory and reconfigure it using "configure" and whatever options you choose, don't try to selectively edit the files. By default, nvi is installed as "vi", with hard links to "ex" and "view". To install them using different names, use the configure program options. For example, to install them as "nvi", "nex" and "nview", use: configure --program-prefix=n See the section below on installation for details. Note, if you're building nvi on a LynxOS system, you should read the README.LynxOS file in this directory for additional build instructions that are specific to that operating system. If you have trouble with this procedure, send email to the addresses listed in ../README. In that email, please provide a complete script of the output for all of the above commands that you entered. =-=-=-=-=-=-= NVI'S OPTIONS TO THE CONFIGURE PROGRAM =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= There are many options that you can enter to the configuration program. To see a complete list of the options, enter "configure --help". Only a few of them are nvi specific. These options are as follows: --disable-re DON'T use the nvi-provided RE routines. --enable-debug Build a debugging version. --enable-perlinterp Include a Perl interpreter in vi. --enable-tclinterp Include a Tk/Tcl interpreter in vi. --enable-gtk Build a gtk front-end. --enable-motif Build a motif front-end. --enable-threads Turn on thread support. --enable-widechar Build a wide character aware vi (experimental). --with-curses=DIR Path to curses installation. --with-db3=db3prefix Path to db3 installation. --enable-dynamic-loading Load DB 3 dynamically. disable-re: By default, nvi loads its own versions of the POSIX 1003.2 Regular Expression routines (which are Henry Spencer's implementation). If your C library contains an implementation of the POSIX 1003.2 RE routines (note, this is NOT the same as the historic UNIX RE routines), and you want to use them instead, enter: --disable-re as an argument to configure, and the RE routines will be taken from whatever libraries you load. Please ensure that your RE routines implement Henry Spencer's extensions for doing vi-style "word" searches. enable-debug: If you want to build nvi with no optimization (i.e. without -O as a compiler flag), with -g as a compiler flag, and with DEBUG defined during compilation, enter: --enable-debug as an argument to configure. enable-perlinterp: If you have the Perl 5 libraries and you want to compile in the Perl interpreter, enter: --enable-perlinterp as an argument to configure. (Note: this is NOT possible with Perl 4, or even with Perl 5 versions earlier than 5.002.) enable-tclinterp: If you have the Tk/Tcl libraries and you want to compile in the Tcl/Tk interpreter, enter: --enable-tclinterp as an argument to configure. If your Tk/Tcl include files and libraries aren't in the standard library and include locations, see the next section of this README file for more information. enable-gtk: If you have the Gtk libraries and you want to build the Gtk nvi front-end, enter: --enable-gtk as an argument to configure. If your Gtk include files and libraries aren't in the standard library and include locations, see the next section of this README file for more information. See also the enable-threads option. enable-motif: If you have the Motif libraries and you want to build the Motif nvi front-end, enter: --enable-motif as an argument to configure. If your Motif include files and libraries aren't in the standard library and include locations, see the next section of this README file for more information. enable-threads: If you want to be able to use multiple windows in the Gtk front-end, you should specify this option. with-curses: Specifies the path where curses is installed. with-db3: Specifies the path where DB3 is installed. See README.DB3 for more information about DB3. enable-dynamic-loading: Dynamically load DB3 library. See README.DB3 for more information about DB3. enable-widechar: Enables support for wide characters. Note that this is still rather experimental. If you try this out on Solaris, you will want to point nvi to the curses in /usr/xpg4/ which is CSI compliant. =-=-=-=-=-=-= ADDING OR CHANGING COMPILERS, OR COMPILE OR LOAD LINE FLAGS =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= If you want to use a specific compiler, specify the CC environment variable before running configure. For example: env CC=gcc configure Using anything other than the native compiler will almost certainly mean that you'll want to check the compile and load line flags, too. If you want to specify additional load line flags, specify the ADDLDFLAGS environment variable before running configure. For example: env ADDLDFLAGS="-Q" configure would specify the -Q flag in the load line when the nvi programs are loaded. If you don't want configure to use the default load line flags for the system, specify the LDFLAGS environment variable before running configure. For example: env LDFLAGS="-32" configure will cause configure to set the load line flags to "-32", and not set them based on the current system. If you want to specify additional compile line flags, specify the ADDCPPFLAGS environment variable before running configure. For example: env ADDCPPFLAGS="-I../foo" configure would cause the compiler to be passed the -I../foo flag when compiling test programs during configuration as well as when building nvi object files. If you don't want configure to use the default compile line flags for the system, specify the CPPFLAGS environment variable before running configure. For example: env CPPFLAGS="-I.." configure will cause configure to use "-I.." as the compile line flags instead of the default values. =-=-=-=-=-=-= ADDING LIBRARIES AND INCLUDE FILES =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= If the Tk/Tcl or any other include files or libraries are in non-standard places on your system, you will need to specify the directory path where they can be found. If you want to specify additional library paths, set the ADDLIBS environment variable before running configure. For example: env ADDLIBS="-L/a/b -L/e/f -ldb" configure would specify two additional directories to search for libraries, /a/b and /e/f, and one additional library to load, "db". If you want to specify additional include paths, specify the ADDCPPFLAGS environment variable before running configure. For example: env ADDCPPFLAGS="-I/usr/local/include" LIBS="-ldb" configure would search /usr/local/include for include files, as well as load the db library as described above. As a final example, let's say that you've downloaded ncurses from the net and you've built it in a directory named ncurses which is at the same level in the filesystem hierarchy as nvi. You would enter something like: env ADDCPPFLAGS="-I../../ncurses/include" \ ADDLIBS="-L../../ncurses/libraries" configure to cause nvi to look for the curses include files and the curses library in the ncurses environment. Notes: Make sure that you prepend -L to any library directory names, and that you prepend -I to any include file directory names! Also, make sure that you quote the paths as shown above, i.e. with single or double quotes around the values you're specifying for ADDCPPFLAGS and ADDLIBS. =-=-=-=-=-= You should NOT need to add any libraries or include files to load the Perl5 interpreter. The configure script will obtain that information directly from the Perl5 program. This means that the configure script must be able to find perl in its path. It looks for "perl5" first, and then "perl". If you're building a Perl interpreter and neither is found, it's a fatal error. =-=-=-=-=-= You do not need to specify additional libraries to load Tk/Tcl, Perl or curses, as the nvi configuration script adds the appropriate libraries to the load line whenever you specify --enable-tknvi or other Perl or Tk/Tcl related option, or build the Tk/Tcl or curses version of nvi. The library names that are automatically loaded are as follows: for Perl: -lperl for Tk/Tcl: -ltk -ltcl -lm for curses: -lcurses In addition, the configure script loads: ... the X libraries when loading the Tk/Tcl libraries, if they exist. ... the -ltermcap or -ltermlib libraries when loading any curses library, if they exist. =-=-=-=-=-= The env command is available on most systems, and simply sets one or more environment variables before running a command. If the env command is not available to you, you can set the environment variables in your shell before running configure. For example, in sh or ksh, you could do: ADDLIBS="-L/a/b -L/e/f -ldb" configure and in csh or tcsh, you could do: setenv ADDLIBS "-L/a/b -L/e/f -ldb" configure See your shell manual page for further information. =-=-=-=-=-=-= INSTALLING NVI =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Nvi installs the following files into the following locations, with the following default values: Variables: Default value: prefix /usr/local exec_prefix $(prefix) bindir $(prefix)/bin datadir $(prefix)/share mandir $(prefix)/man File(s): Default location ---------------------------------------- vi $(bindir)/vi vi.1 $(mandir)/man1/vi.1 vi.0 $(mandir)/cat1/vi.0 Perl scripts $(datadir)/vi/perl/ Tcl scripts $(datadir)/vi/tcl/ Message Catalogs $(datadir)/vi/catalog/ Notes: There are two hard links to the vi program, named ex and view. Similarly, there are two hard links to the unformatted vi manual page, named ex.1 and view.1, and two hard links to the formatted manual page, named ex.0 and view.0. These links are created when the program and man pages are installed. If you want to install vi, ex, view and the man pages as nvi, nex, nview, use the configure option --program-prefix=n. Other, more complex transformations are possible -- use configure --help to see more options. To move the entire installation tree somewhere besides /usr/local, change the value of both "exec_prefix" and "prefix". To move the binaries to a different place, change the value of "bindir". Similarly, to put the datafiles (the message catalogs, Perl and Tcl scripts) or the man pages in a different place, change the value of "datadir" or "mandir". These values can be changed as part of configuration: configure --exec_prefix=/usr/contrib --prefix=/usr/share or when doing the install itself: make exec_prefix=/usr/contrib prefix=/usr/contrib install The datafile directory (e.g., /usr/local/share/vi by default) is completely removed and then recreated as part of the installation process. =-=-=-=-=-=-= NVI AND THE CURSES LIBRARY =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The major portability problem for nvi is selecting a curses library. Unfortunately, it is common to find broken versions of curses -- the original System V curses was broken, resulting in all vendors whose implementations are derived from System V having broken implementations in turn. If you use the vendor's or other curses library, and you see any of the following symptoms: + Core dumps in curses routines. + Missing routines when compiling. + Repainting the wrong characters on the screen. + Displaying inverse video in the wrong places. + Failure to reset your terminal to the correct modes on exit. you have a broken curses implementation, and you should reconfigure nvi to use another curses library. An alternative for your vendor's curses is ncurses, available from ftp://ftp.gnu.org/pub/gnu/ncurses/ One final note. If you see the following symptoms: + Line-by-line screen repainting instead of scrolling. it usually means that your termcap or terminfo information is insufficient for the terminal. nvi-1.81.6/build.unix/README.LynxOS0100644000076400001440000003504310720065506015613 0ustar skimousersREADME.LynxOS ============= Written by Ronald F. Guilmette Last modified Wed Aug 14 23:10:07 PDT 1996 ------------------------------------------ 0. Introduction --------------- This file describes how to build and install the Berkeley nvi editor for the LynxOS 2.4.0 operating system. LynxOS 2.4.0 is available for a variety of different hardware platforms, in particular, x86, m680x0, Sparc, and PowerPC. I have successfully built nvi on all four of these flavors of LynxOS by following the procedures given in this file. Note that these procedures may not work on versions of LynxOS prior to 2.4.0. (As I understand it, a good deal of work went into making the 2.4.0 release more POSIX-compliant, and I have no idea what build glitches, if any, you might encounter if you try to build nvi on a pre-2.4.0 version of LynxOS.) There are basically four steps to configuring, building, and installing nvi on LynxOS, namely: 1. Get setup to use the proper C compiler. 2. Replace your installed `tr' program. 3. Fix your system include files. 4. Do a normal configure, build, and install of nvi. These steps are described in separate sections below. 1. Get Setup to Use the Proper C Compiler ------------------------------------------ The first step when building nvi on LynxOS is to set your $PATH environment variable properly so that the gcc 2.x compiler appears first on your path, prior to the older (and less robust) gcc 1.xx compiler (typically installed as /bin/gcc) and/or the old Lynx proprietary C compiler (typically installed as /bin/cc), both of which may also be present on your system. Note that for most operating systems, the configure script for nvi tries to use whatever compiler you have installed (and in your $PATH) as "cc", however in the special case of LynxOS, the configure script will auto- matically try to find a "gcc" program on your $PATH in preference to a compiler called "cc". If the nvi configure script only find a compiler called "cc", that's OK. It will still try to see if that is really just the GNU C compiler installed under the name "cc". Regardless of the name however (be it "gcc" or "cc") the first C compiler in your $PATH should be some _recent_ (i.e. 2.0 or later) version of the GNU C compiler... and the nvi configure script now checks that this is the case, and fails if it isn't. Oddly enough, LynxOS 2.4.0 (and some prior versions) shipped with as many as three different C compilers installed, so it is important to set your $PATH environment variable carfully in order to get the proper C compiler to appear first in your $PATH. You want to avoid having either the /bin/gcc compiler or the /bin/cc compiler be the first C compiler in your $PATH. To make sure that the GNU C version 2.x compiler which was shipped with your LynxOS system appears first on your path, you will need to either set your $PATH variable (for sh/bash/ksh users) or your $path variable (for csh/tcsh users). You can, of course, just do this at the shell command prompt, but it is probably better to actually edit this change into your .profile file (for sh/bash/ksh users) or into your .cshrc file (for csh/tcsh users). The pathname of the directory that contains the GNU C version 2.x compiler is (unfortunately) dependent upon the exact type of LynxOS system you have. For LynxOS 2.4.0 on x86 systems, gcc 2.x is located in: /cygnus/94q4-lynxos-x86/bin For LynxOS 2.4.0 on m680x0 systems, gcc 2.x is located in: /cygnus/94q4-lynxos-68k/bin For LynxOS 2.4.0 on Sparc systems, gcc 2.x is located in: /cygnus/94q4-lynxos-usparc/bin For LynxOS 2.4.0 on PowerPC systems, gcc 2.x is located in: /cygnus/95q2-lynxos-ppc/bin (Note also that these locations may change in LynxOS 2.5.x and beyond.) Anyway, it is imperative that you setup your $PATH environment variable (*before* you do the configure step for nvi) so that the GNU C version 2.x compiler appears in your $PATH before either the /bin/cc or /bin/gcc compilers (if present). If you fail to do this, the configure step for nvi will fail, because the compiler script actually checks (now) that the compiler you are using (if your are on a LynxOS system) is gcc 2.0 or later. To make absolutely sure that you will be configuring and building nvi with the proper C compiler (i.e. the GNU C version 2.x compiler on your system) you should add the directory name listed above for your specific system type to your $PATH setting in your $HOME/.profile file. (For csh/tcsh users, you will instead want to add the relevant directory name to the setting of your $path variable in your ~/.cshrc file.) Once you have added the proper direc- tory name (from the list given above) to your $HOME/.profile file (or to your ~/.cshrc file, if you are using csh or tcsh) you should log out completely and then log back into the system just to make sure your new $PATH/$path setting takes effect properly. When you finish making this adjustment to your $PATH (or $path), the most up-to-date version of gcc on your system should be available to you as the first `gcc' program on your $PATH. You should verify that this is indeed the case simply by typing `gcc -v' and then checking the version number reported by the compiler. It should say either "2.6-94q4" or (on PowerPC systems) it should say "2.6-95q2". If you don't get these results, try again to set your $PATH (or $path) until you do. You won't be able to build nvi until you are properly setup to use gcc version 2.0 or later. Performing the steps shown above will insure that your subsequent configura- tion and build steps for nvi will make use of the most up-to-date version of gcc that was shipped with your Lynx operating system. (Note that the versions of gcc which are currently shipping with LynxOS 2.4.0 are also somewhat out- of-date themselves, but they are still quite a bit newer and more bug-free and ANSI conformant that those other two C compilers, /bin/cc and /bin/gcc, which also ship with LynxOS 2.4.0.) (Note: At present, LynxOS version 2.4.0 is the latest officially released version of LynxOS, and all of the above information is accurate and correct for LynxOS 2.4.0 as of the time of this writing. However it is rumored that future releases of LynxOS may provide a still newer version of gcc, and that it may be located in the /usr/bin directory. Thus, if you are building nvi for some LynxOS version later than 2.4.0, you may wish to check and see if your system has a program called /usr/bin/gcc, and use that version of gcc, if available, rather than the one suggested above.) 2. Replace Your Installed `tr' Program --------------------------------------- The `tr' program which comes bundled with LynxOS 2.4.0 (as /bin/tr) has a somewhat obscure bug which just happens to be tickled by almost all GNU `autoconf' generated `configure' scripts (including the one that nowadays comes bundled with nvi). Using the stock /bin/tr program on LynxOS when executing such `configure' scripts _will_ cause these scripts to malfunction in various ways. It is therefore imperative that you replace your LynxOS /bin/tr program with a properly working version of the `tr' command _before_ you even try to configure nvi. (You can tell if your `tr' program has the bug by executng the command "echo ab- | tr ab- ABC". If this yields the string "Ab-" then you have the bug. If it yields "ABC" then you don't.) You can obtain sources for a working version of the `tr' command as part of the GNU `textutils' package (the latest version of which, at the time of this writing, is 1.19). The GNU textutils package is available for downloading from prep.ai.mit.edu in the pub/gnu directory. Look for the file named textutils-1.19.tar.gz, or an even more recent version of textutils, if one is available. Fetch it, gunzip it, untar it, and follow the directions in the INSTALL file included in the tar file to build and install the entire textutils set of utility programs (which includes a working `tr' program). Then just make sure that the GNU version of `tr' appears on your $PATH _before_ the LynxOS version of `tr' (i.e. /bin/tr). Be sure to do this step _before_ you start to configure nvi. When building the textutils set of programs, I suggest that you use the most up-to-date C compiler available on your system (as described above). Also, note that it will be important for you to AVOID using the -O (optimize) compiler option when building the GNU textutils package, even if you are using the most up-to-date version of gcc which shipped with your system. If you try to use -O when building the textutils package on an x86 with the Cygnus 94q4 C compiler, you will end up with a `tr' program which will malfunction even worse than the one you are trying to replace! If you use -O when building the textutils package on LynxOS on the PowerPC (using the Cygnus 95q2 C compiler) you will just get yourself a compiler crash. So just don't use -O when building textutils. You can avoid using -O by in- voking make in the textutils directory as follows: make CFLAGS="-g" (Note: At present, LynxOS version 2.4.0 is the latest officially released version of LynxOS, and all of the above information is accurate and correct for LynxOS 2.4.0 as of the time of this writing. However it is rumored that the bug in the /bin/tr program will be fixed in future releases of LynxOS, so if you have a version of LynxOS later than 2.4.0, you may wish to check and see if your /bin/tr program even has the problematic bug before bothering with all of this.) 3. Fix Your System Include Files --------------------------------- If you are building nvi on a PowerPC system, it is also important that you apply the patches given at the end of this file to your /usr/include files. (Note that you will have to be root in order to do this.) Two of the patches included below fix a pair of serious bugs in the /usr/include/stdarg.h file on the PowerPC, and you really _do_ want to have these bugs fixed anyway, because without these fixes, anything that you compile which uses will very likely malfunction at run-time. Regardless of which LynxOS platform you are using (i.e. x86, PowerPC, Sparc, or m680x0) you may want to apply all of the system include files patches that are included below anyway. Doing so will clean up a few minor problems with the relevant system include files (i.e. , , and ) and this step will also prevent a few warnings which you would otherwise get during the build of nvi. You can apply all of the patches given at the end of this file simply by doing the following: su root cd /usr/include /bin/patch < this-file Where `this-file' is the actual full pathname of the file you are now reading, wherever it may reside on your own system. (Note: At present, LynxOS version 2.4.0 is the latest officially released version of LynxOS, and all of the above information is accurate and correct for LynxOS 2.4.0 as of the time of this writing. However it is rumored that future releases of LynxOS may incorporate some or all of the important system include file fixes provided below. Thus, if you are building nvi for some LynxOS version later than 2.4.0, you should probably go ahead and try to apply the patches given below to your system include files, and then just don't worry about it if these patches seem to have already been applied.) 4. A Brief Note about Sendmail ------------------------------- I should mention also that LynxOS does not normally ship with the `sendmail' mail transfer program installed, either under /usr/lib/ or anywhere else for that matter. This isn't really a big problem, but nvi normally wants and expects to have a sendmail program available so that it can send users notifi- cations (by mail) whenever a partially edited file is preserved by the editor in response to a sudden system crash, a sudden system shutdown, or an unexpect- ed serial-line hangup. You can configure and build nvi without any sendmail program installed on your system, but you will get warnings about its absence when you are doing the initial configure step prior to actually building nvi. If you want to have a fully-functional nvi which does send out notification messages (by mail) whenever partially edited files are preserved during a serial line hangup or system crash, then you should get the BSD sendmail sources (via ftp from ftp.cs.berkeley.edu), build and install sendmail, and then reconfigure, rebuild, and reinstall nvi. Please contact me at the E-mail address below if you experience any problems in building or using nvi on LynxOS. I make no guarrantees, but I may be willing to try to help.

Please give ncurses a try when you encounter a screen output problem. Apparently, the more recent Solaris compilers invoke the incremental linker, `ild', when the "-g" option is used and one or more "xxx.o" files are specified on the command line during the link phase. Unfortunately, the executable produced is up to 3-4 times as big as an executable generated by the standard linker `ld'. You can bypass this by adding "-xildoff" to LDFLAGS or by setting CFLAGS (to something that does not contain "-g"). nvi-1.81.6/catalog/0040755000076400001440000000000010720065506013067 5ustar skimousersnvi-1.81.6/catalog/Makefile0100644000076400001440000000477210720065506014536 0ustar skimousers# $Id: Makefile,v 8.30 1996/11/27 11:59:09 bostic Exp $ (Berkeley) $Date: 1996/11/27 11:59:09 $ CAT= dutch english french german ru_SU.KOI8-R spanish swedish FILES= ../cl/*.c ../common/*.c ../ex/*.c ../vi/*.c all: dump ${CAT} ${CAT}: english.base @echo "... $@"; \ rm -f $@; \ sort -u $@.base | \ awk '{ \ if ($$1 == 1) { \ print "\nMESSAGE NUMBER 1 IS NOT LEGAL"; \ exit 1; \ } \ if (++nline > $$1) { \ print "DUPLICATE MESSAGE NUMBER " $$1; \ exit 1; \ } \ for (; nline < $$1; ++nline) \ print ""; \ print $0; \ }' | \ sed -e '1s/^/VI_MESSAGE_CATALOG/' \ -e '/"/s/^[^"]*"//' \ -e '1!s/"$$/X/' > $@; \ chmod 444 $@; \ if grep DUPLICATE $@ > /dev/null; then \ grep DUPLICATE $@; \ fi; \ if grep 'NOT LEGAL' $@ > /dev/null; then \ grep 'NOT LEGAL' $@; \ fi CHK= dutch.check english.check french.check german.check \ ru_SU.KOI8-R.check spanish.check swedish.check check: ${CHK} ${CHK}: ${CAT} @echo "... $@"; \ f=`basename $@ .check`; \ (echo "Unused message id's (this is okay):"; \ awk '{ \ while (++nline < $$1) \ printf "%03d\n", nline; \ }' < $$f.base; \ echo =========================; \ echo "MISSING ERROR MESSAGES (Please add!):"; \ awk '{print $$1}' < $$f.base | sort -u > __ck1; \ awk '{print $$1}' < english.base | sort -u > __ck2; \ comm -13 __ck1 __ck2; \ echo =========================; \ echo "Extra error messages (just delete them):"; \ comm -23 __ck1 __ck2; \ echo =========================; \ echo "MESSAGES WITH THE SAME MESSAGE ID's (FIX!):"; \ for j in \ `sed '/^$$/d' < $$f.base | sort -u | \ awk '{print $$1}' | uniq -d`; do \ egrep $$j $$f.base; \ done; \ echo =========================; \ echo "Duplicate messages, both id and message (this is okay):"; \ sed '/^$$/d' < $$f.base | sort | uniq -c | \ awk '$$1 != 1 { print $$0 }' | sort -n; \ echo =========================; \ echo "Duplicate messages, just message (this is okay):"; \ sed '/^$$/d' < $$f | sort | uniq -c | \ awk '$$1 != 1 { print $$0 }' | sort -n; \ echo =========================) > $@ english.base: dump ${FILES} #Makefile ./dump ${FILES} |\ sed -e '/|/!d' \ -e 's/|/ "/' \ -e 's/^"//' \ -e 's/\\"/"/g' |\ sort -n > $@ dump: dump.c ${CC} -O -o dump dump.c clean: rm -f dump dump.o ${CAT} english.base *.check __ck1 __ck2 nvi-1.81.6/catalog/README0100644000076400001440000001526610720065506013756 0ustar skimousers# $Id: README,v 8.4 1994/11/22 09:52:04 bostic Exp $ (Berkeley) $Date: 1994/11/22 09:52:04 $ Generally, all non-system error and informational messages in nvi are catalog messages, i.e. they can be tailored to a specific langauge. Command strings, usage strings, system errors and other "known text" are not. It would certainly be possible to internationalize all the text strings in nvi, but it's unclear that it's the right thing to do. First, there's no portable way to do message catalogs. The System V scheme is a reasonable choice, but none of the 4BSD derived systems support it. So, catalogs are completely implemented within nvi, and don't require any library support. Message catalogs in nvi are fairly simple. Every catalog message consists of two parts -- an initial number followed by a pipe (`|') character, followed by the English text for the message. For example: msgq(sp, M_ERR, "001|This is an error message"); would be a typical message. When the msgq() routine is called, if the user has specified a message catalog and the format string (the third argument) has a leading number, then it is converted to a record number, and that record is retrieved from the message catalog and used as a replacement format string. If the record can't be retrieved for any reason, the English text is displayed instead. Each message format string MUST map into the English format string, i.e. it can't display more or different arguments than the English one. For example: msgq(sp, M_ERR, "002|Error: %d %x", arg1, arg2); is a format string that displays two arguments. It is possible, however, to reorder the arguments or to not display all of them. The convention nvi uses is the System V printf(3) convention, i.e. "%[0-9]*$" is the name of a specific, numbered argument. For example: msgq(sp, M_ERR, "002|Error: %2$d %1$x", arg1, arg2); displays the arguments in reverse order. If the system supports this convention in its library printf routines (as specified by the test #define NL_ARGMAX), nvi uses those routines. Otherwise, there is some serious magic going on in common/msg.c to make this all work. Arguments to the msgq function are required to contain ONLY printable characters. No further translation is done by the msgq routine before displaying the message on the screen. For example, in the msgq call: msgq(sp, M_ERR, "003|File: %s", file_name); "file_name" must contain only printable characters. The routine msg_print() returns a printable version of a string in allocated memory. For example: char *p; p = msg_print(sp, file_name); msgq(sp, M_ERR, M("003", "File: %s"), p); FREE_SPACE(sp, p, 0); makes sure that "file_name" is printable before calling the msgq routine. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= The message catalogs themselves are maintained in two files. The first is the "base file" which contains two fields, a record number and the message itself. All base files are named using the convention "vi_.base", e.g. the English one is "vi_english.base". For example: 002 "Unable to create temporary file" 003 "Warning: %s is not a regular file" 004 "%s already locked, session is read-only" 005 "%s: remove" 006 "%s: close" 007 "%s: remove" 008 "%s: remove" 009 "Read-only file, not written; use ! to override" 010 "Read-only file, not written" are the first few lines of the current vi_english.base file. Note that message #1 is missing -- the first message of each catalog is a special one, so that nvi can recognize message catalog files. It's added by the Makefile script that creates the second version of the message catalog. The second file is the file used by nvi to access messages, and is a list of the messages, one per line: VI_MESSAGE_CATALOG Unable to create temporary fileX Warning: %s is not a regular fileX %s already locked, session is read-onlyX %s: removeX %s: closeX %s: removeX %s: removeX Read-only file, not written; use ! to overrideX Read-only file, not writtenX Note that all messages have had a trailing 'X' character appended. This is to provide nvi a place to store a trailing nul for the message so that C library routines that expect one won't be disappointed. These files are named for their language, e.g. "vi_english". The second files are automatically created from the first files. To create a new catalog for nvi: Copy the file vi_english.base to a file that you can modify , e.g. "cp vi_english.base vi_german.base". For each of the messages in the file, replace the message with the string that you want to use. To find out what the arguments to a message are, I'm afraid you'll have to search the source code for the message number. You can find them fairly quickly by doing: cd ..; egrep '123\|' */*.[chys] I'm sorry that there's not an easier way, but I couldn't think of anything that wasn't a lot of work. If, for some reason, you don't have the file vi_english.base, or you have new sources for which you want to create a new base catalog, you can create it by running the command "make english" in the catalog directory. Once you've translated all of the strings, then add your catalog to the "CAT=" line of the Makefile, and run the command "make catalog". This will create the second (and corresponding) file for each file named .base. Don't worry about missing line numbers, i.e. base files that look like: 005 Message number 5. 007 Message number 7. This simply means that a message was deleted during the course of nvi's development. It will be taken care of automatically when you create the second form of the file. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= If you add new messages to the nvi sources, you can check your work by doing "make english; make check". The "make check" target lists unused message numbers, duplicate message numbers, and duplicate messages. Unused message numbers are only useful if you are condensing messages. Duplicate message numbers are a serious problem and have to be fixed. Duplicate messages are only interesting if a message appears often enough that it's worth creating a routine so that the string is only need in a single place. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= To select a catalog when running nvi, set the "msgcat" option. If the value of this option ends with a '/', it is treated as the name of a directory that contains a message catalog "vi_XXXX", where XXXX is the value of the LANG environmental variable, if it's set, or the value of the LC_MESSAGES environmental variable if it's not. If neither of those environmental variables are set, or if the option doesn't end in a '/', the option is treated as the full path name of the message catalog to use. If any messages are missing from the catalog, the backup text (English) is used instead. nvi-1.81.6/catalog/dump.c0100644000076400001440000000302010720065506014170 0ustar skimousers/*- * Copyright (c) 1992, 1993, 1994 * The Regents of the University of California.

The assumptions: 1: The DB routines are not reentrant. 2: The curses routines may not be reentrant. 3: Neither DB nor curses will restart system calls. XXX Note, most C library functions don't restart system calls. So, we should *probably* start blocking around any imported function that we don't know doesn't make a system call. This is going to be a genuine annoyance... SIGHUP, SIGTERM Used for file recovery. The DB routines can't be reentered, nor can they handle interrupted system calls, so the vi routines that call DB block signals. This means that DB routines could be called at interrupt time, if necessary. SIGQUIT Disabled by the signal initialization routines. Historically, ^\ switched vi into ex mode, and we continue that practice. SIGWINCH: The interrupt routine sets a global bit which is checked by the key-read routine, so there are no reentrancy issues. This means that the screen will not resize until vi runs out of keys, but that doesn't seem like a problem. SIGINT and SIGTSTP are a much more difficult issue to resolve. Vi has to permit the user to interrupt long-running operations. Generally, a search, substitution or read/write is done on a large file, or, the user creates a key mapping with an infinite loop. This problem will become worse as more complex semantics are added to vi, especially things like making it a pure text widget. There are four major solutions on the table, each of which have minor permutations. 1: Run in raw mode. The up side is that there's no asynchronous behavior to worry about, and obviously no reentrancy problems. The down side is that it's easy to misinterpret characters (e.g. :w big_file^Mi^V^C is going to look like an interrupt) and it's easy to get into places where we won't see interrupt characters (e.g. ":map a ixx^[hxxaXXX" infinitely loops in historic implementations of vi). Periodically reading the terminal input buffer might solve the latter problem, but it's not going to be pretty. Also, we're going to be checking for ^C's and ^Z's both, all over the place -- I hate to litter the source code with that. For example, the historic version of vi didn't permit you to suspend the screen if you were on the colon command line. This isn't right. ^Z isn't a vi command, it's a terminal event. (Dammit.) 2: Run in cbreak mode. There are two problems in this area. First, the current curses implementations (both System V and Berkeley) don't give you clean cbreak modes. For example, the IEXTEN bit is left on, turning on DISCARD and LNEXT. To clarify, what vi WANTS is 8-bit clean, with the exception that flow control and signals are turned on, and curses cbreak mode doesn't give you this. We can either set raw mode and twiddle the tty, or cbreak mode and twiddle the tty. I chose to use raw mode, on the grounds that raw mode is better defined and I'm less likely to be surprised by a curses implementation down the road. The twiddling consists of setting ISIG, IXON/IXOFF, and disabling some of the interrupt characters (see the comments in cl_init.c). This is all found in historic System V (SVID 3) and POSIX 1003.1-1992, so it should be fairly portable. The second problem is that vi permits you to enter literal signal characters, e.g. ^V^C. There are two possible solutions. First, you can turn off signals when you get a ^V, but that means that a network packet containing ^V and ^C will lose, since the ^C may take effect before vi reads the ^V. (This is particularly problematic if you're talking over a protocol that recognizes signals locally and sends OOB packets when it sees them.) Second, you can turn the ^C into a literal character in vi, but that means that there's a race between entering ^V^C, i.e. the sequence may end up being ^V^C. Also, the second solution doesn't work for flow control characters, as they aren't delivered to the program as signals. Generally, this is what historic vi did. (It didn't have the curses problems because it didn't use curses.) It entered signals following ^V characters into the input stream, (which is why there's no way to enter a literal flow control character). 3: Run in mostly raw mode; turn signals on when doing an operation the user might want to interrupt, but leave them off most of the time. This works well for things like file reads and writes. This doesn't work well for trying to detect infinite maps. The problem is that you can write the code so that you don't have to turn on interrupts per keystroke, but the code isn't pretty and it's hard to make sure that an optimization doesn't cover up an infinite loop. This also requires interaction or state between the vi parser and the key reading routines, as an infinite loop may still be returning keys to the parser. Also, if the user inserts an interrupt into the tty queue while the interrupts are turned off, the key won't be treated as an interrupt, and requiring the user to pound the keyboard to catch an interrupt window is nasty. 4: Run in mostly raw mode, leaving signals on all of the time. Done by setting raw mode, and twiddling the tty's termios ISIG bit. This works well for the interrupt cases, because the code only has to check to see if the interrupt flag has been set, and can otherwise ignore signals. It's also less likely that we'll miss a case, and we don't have to worry about synchronizing between the vi parser and the key read routines. The down side is that we have to turn signals off if the user wants to enter a literal character (e.g. ^V^C). If the user enters the combination fast enough, or as part of a single network packet, the text input routines will treat it as a signal instead of as a literal character. To some extent, we have this problem already, since we turn off flow control so that the user can enter literal XON/XOFF characters. This is probably the easiest to code, and provides the smoothest programming interface. There are a couple of other problems to consider. First, System V's curses doesn't handle SIGTSTP correctly. If you use the newterm() interface, the TSTP signal will leave you in raw mode, and the final endwin() will leave you in the correct shell mode. If you use the initscr() interface, the TSTP signal will return you to the correct shell mode, but the final endwin() will leave you in raw mode. There you have it: proof that drug testing is not making any significant headway in the computer industry. The 4BSD curses is deficient in that it does not have an interface to the terminal keypad. So, regardless, we have to do our own SIGTSTP handling. The problem with this is that if we do our own SIGTSTP handling, in either models #3 or #4, we're going to have to call curses routines at interrupt time, which means that we might be reentering curses, which is something we don't want to do. Second, SIGTSTP has its own little problems. It's broadcast to the entire process group, not sent to a single process. The scenario goes something like this: the shell execs the mail program, which execs vi. The user hits ^Z, and all three programs get the signal, in some random order. The mail program goes to sleep immediately (since it probably didn't have a SIGTSTP handler in place). The shell gets a SIGCHLD, does a wait, and finds out that the only child in its foreground process group (of which it's aware) is asleep. It then optionally resets the terminal (because the modes aren't how it left them), and starts prompting the user for input. The problem is that somewhere in the middle of all of this, vi is resetting the terminal, and getting ready to send a SIGTSTP to the process group in order to put itself to sleep. There's a solution to all of this: when vi starts, it puts itself into its own process group, and then only it (and possible child processes) receive the SIGTSTP. This permits it to clean up the terminal and switch back to the original process group, where it sends that process group a SIGTSTP, putting everyone to sleep and waking the shell. Third, handing SIGTSTP asynchronously is further complicated by the child processes vi may fork off. If vi calls ex, ex resets the terminal and starts running some filter, and SIGTSTP stops them both, vi has to know when it restarts that it can't repaint the screen until ex's child has finished running. This is solveable, but it's annoying. Well, somebody had to make a decision, and this is the way it's going to be (unless I get talked out of it). SIGINT is handled asynchronously, so that we can pretty much guarantee that the user can interrupt any operation at any time. SIGTSTP is handled synchronously, so that we don't have to reenter curses and so that we don't have to play the process group games. ^Z is recognized in the standard text input and command modes. (^Z should also be recognized during operations that may potentially take a long time. The simplest solution is probably to twiddle the tty, install a handler for SIGTSTP, and then restore normal tty modes when the operation is complete.) nvi-1.81.6/cl/cl.h0100644000076400001440000000640110720065506012620 0ustar skimousers/*- * Copyright (c) 1993, 1994 * The Regents of the University of California.

First, the idea of * mapping keys is that one or more keystrokes act like a function key. * What's going on is that vi is reading a number, and the character following * the number may or may not be mapped (EC_MAPCOMMAND). For example, if the * user is entering the z command, a valid command is "z40+", and we don't want * to map the '+', i.e. if '+' is mapped to "xxx", we don't want to change it * into "z40xxx". However, if the user enters "35x", we want to put all of the * characters through the mapping code. * * Historical practice is a bit muddled here. (Surprise!) It always permitted * mapping digits as long as they weren't the first character of the map, e.g. * ":map ^A1 xxx" was okay. It also permitted the mapping of the digits 1-9 * (the digit 0 was a special case as it doesn't indicate the start of a count) * as the first character of the map, but then ignored those mappings. While * it's probably stupid to map digits, vi isn't your mother. * * The way this works is that the EC_MAPNODIGIT causes term_key to return the * end-of-digit without "looking" at the next character, i.e. leaving it as the * user entered it. Presumably, the next term_key call will tell us how the * user wants it handled. * * There is one more complication. Users might map keys to digits, and, as * it's described above, the commands: * * :map g 1G * d2g * * would return the keys "d21G", when the user probably wanted * "d21G". So, if a map starts off with a digit we continue as * before, otherwise, we pretend we haven't mapped the character, and return * . * * Now that that's out of the way, let's talk about Energizer Bunny macros. * It's easy to create macros that expand to a loop, e.g. map x 3x. It's * fairly easy to detect this example, because it's all internal to term_key. * If we're expanding a macro and it gets big enough, at some point we can * assume it's looping and kill it. The examples that are tough are the ones * where the parser is involved, e.g. map x "ayyx"byy. We do an expansion * on 'x', and get "ayyx"byy. We then return the first 4 characters, and then * find the looping macro again. There is no way that we can detect this * without doing a full parse of the command, because the character that might * cause the loop (in this case 'x') may be a literal character, e.g. the map * map x "ayy"xyy"byy is perfectly legal and won't cause a loop. * * Historic vi tried to detect looping macros by disallowing obvious cases in * the map command, maps that that ended with the same letter as they started * (which wrongly disallowed "map x 'x"), and detecting macros that expanded * too many times before keys were returned to the command parser. It didn't * get many (most?) of the tricky cases right, however, and it was certainly * possible to create macros that ran forever. And, even if it did figure out * what was going on, the user was usually tossed into ex mode. Finally, any * changes made before vi realized that the macro was recursing were left in * place. We recover gracefully, but the only recourse the user has in an * infinite macro loop is to interrupt. * * !!! * It is historic practice that mapping characters to themselves as the first * part of the mapped string was legal, and did not cause infinite loops, i.e. * ":map! { {^M^T" and ":map n nz." were known to work. The initial, matching * characters were returned instead of being remapped. * * !!! * It is also historic practice that the macro "map ] ]]^" caused a single ] * keypress to behave as the command ]] (the ^ got the map past the vi check * for "tail recursion"). Conversely, the mapping "map n nn^" went recursive. * What happened was that, in the historic vi, maps were expanded as the keys * were retrieved, but not all at once and not centrally. So, the keypress ] * pushed ]]^ on the stack, and then the first ] from the stack was passed to * the ]] command code. The ]] command then retrieved a key without entering * the mapping code. This could bite us anytime a user has a map that depends * on secondary keys NOT being mapped. I can't see any possible way to make * this work in here without the complete abandonment of Rationality Itself. * * XXX * The final issue is recovery.

In the EXF structure, we maintain full * paths of a b+tree file and a mail recovery file. The former is the file * used as backing store by the DB package. The latter is the file that * contains an email message to be sent to the user if we crash. The two * simple states of recovery are: * * + first starting the edit session: * the b+tree file exists and is mode 700, the mail recovery * file doesn't exist. * + after the file has been modified: * the b+tree file exists and is mode 600, the mail recovery * file exists, and is exclusively locked. * * In the EXF structure we maintain a file descriptor that is the locked * file descriptor for the mail recovery file. NOTE: we sometimes have to * do locking with fcntl(2). This is a problem because if you close(2) any * file descriptor associated with the file, ALL of the locks go away. Be * sure to remember that if you have to modify the recovery code. (It has * been rhetorically asked of what the designers could have been thinking * when they did that interface. The answer is simple: they weren't.) * * To find out if a recovery file/backing file pair are in use, try to get * a lock on the recovery file. * * To find out if a backing file can be deleted at boot time, check for an * owner execute bit. (Yes, I know it's ugly, but it's either that or put * special stuff into the backing file itself, or correlate the files at * boot time, neither of which looks like fun.) Note also that there's a * window between when the file is created and the X bit is set. It's small, * but it's there. To fix the window, check for 0 length files as well. * * To find out if a file can be recovered, check the F_RCV_ON bit. Note, * this DOES NOT mean that any initialization has been done, only that we * haven't yet failed at setting up or doing recovery. * * To preserve a recovery file/backing file pair, set the F_RCV_NORM bit. * If that bit is not set when ending a file session: * If the EXF structure paths (rcv_path and rcv_mpath) are not NULL, * they are unlink(2)'d, and free(3)'d. * If the EXF file descriptor (rcv_fd) is not -1, it is closed. * * The backing b+tree file is set up when a file is first edited, so that * the DB package can use it for on-disk caching and/or to snapshot the * file. When the file is first modified, the mail recovery file is created, * the backing file permissions are updated, the file is sync(2)'d to disk, * and the timer is started. Then, at RCV_PERIOD second intervals, the * b+tree file is synced to disk. RCV_PERIOD is measured using SIGALRM, which * means that the data structures (SCR, EXF, the underlying tree structures) * must be consistent when the signal arrives. * * The recovery mail file contains normal mail headers, with two additions, * which occur in THIS order, as the FIRST TWO headers: * * X-vi-recover-file: file_name * X-vi-recover-path: recover_path * * Since newlines delimit the headers, this means that file names cannot have * newlines in them, but that's probably okay. As these files aren't intended * to be long-lived, changing their format won't be too painful. * * Btree files are named "vi.XXXX" and recovery files are named "recover.XXXX". */ #define VI_FHEADER "X-vi-recover-file: " #define VI_PHEADER "X-vi-recover-path: " static int rcv_copy __P((SCR *, int, char *)); static void rcv_email __P((SCR *, char *)); static char *rcv_gets __P((char *, size_t, int)); static int rcv_mailfile __P((SCR *, int, char *)); static int rcv_mktemp __P((SCR *, char *, char *, int)); /* * rcv_tmp -- * Build a file name that will be used as the recovery file. * * PUBLIC: int rcv_tmp __P((SCR *, EXF *, char *)); */ int rcv_tmp(SCR *sp, EXF *ep, char *name) { struct stat sb; int fd; char *dp, path[MAXPATHLEN]; /* * !!! * ep MAY NOT BE THE SAME AS sp->ep, DON'T USE THE LATTER. * * * If the recovery directory doesn't exist, try and create it.

Typically, an application B will invoke ExtUtils::Embed functions while building your application. =head1 @EXPORT ExtUtils::Embed exports the following functions: L, L, L, L, L, L, L, L, L =head1 FUNCTIONS =item xsinit() Generate C/C++ code for the XS intializer function. When invoked as C<`perl -MExtUtils::Embed -e xsinit --`> the following options are recognized: B<-o> (Defaults to B) B<-o STDOUT> will print to STDOUT. B<-std> (Write code for extensions that are linked with the current Perl.) Any additional arguments are expected to be names of modules to generate code for. When invoked with parameters the following are accepted and optional: C Where, B<$filename> is equivalent to the B<-o> option. B<$std> is boolean, equivalent to the B<-std> option. B<[@modules]> is an array ref, same as additional arguments mentioned above. =item Examples perl -MExtUtils::Embed -e xsinit -- -o xsinit.c Socket This will generate code with an B function that glues the perl B function to the C B function and writes it to a file named "xsinit.c". Note that B is a special case where it must call B directly. perl -MExtUtils::Embed -e xsinit This will generate code for linking with B and each static extension found in B<$Config{static_ext}>. The code is written to the default file name B. perl -MExtUtils::Embed -e xsinit -- -o xsinit.c -std DBI DBD::Oracle Here, code is written for all the currently linked extensions along with code for B and B. If you have a working B then there is rarely any need to statically link in any other extensions. =item ldopts() Output arguments for linking the Perl library and extensions to your application. When invoked as C<`perl -MExtUtils::Embed -e ldopts --`> the following options are recognized: B<-std> Output arguments for linking the Perl library and any extensions linked with the current Perl. B<-I> Search path for ModuleName.a archives. Default path is B<@INC>. Library archives are expected to be found as B For example, when looking for B relative to a search path, we should find B When looking for B relative to a search path, we should find B Keep in mind, you can always supply B as an additional linker argument. B<--> Additional linker arguments to be considered. Any additional arguments found before the B<--> token are expected to be names of modules to generate code for. When invoked with parameters the following are accepted and optional: C Where, B<$std> is boolean, equivalent to the B<-std> option. B<[@modules]> is equivalent to additional arguments found before the B<--> token. B<[@link_args]> is equivalent to arguments found after the B<--> token. B<$path> is equivalent to the B<-I> option. In addition, when ldopts is called with parameters, it will return the argument string rather than print it to STDOUT. =item Examples perl -MExtUtils::Embed -e ldopts This will print arguments for linking with B, B and extensions found in B<$Config{static_ext}>. This includes libraries found in B<$Config{libs}> and the first ModuleName.a library for each extension that is found by searching B<@INC> or the path specifed by the B<-I> option. In addition, when ModuleName.a is found, additional linker arguments are picked up from the B file in the same directory. perl -MExtUtils::Embed -e ldopts -- -std Socket This will do the same as the above example, along with printing additional arguments for linking with the B extension. perl -MExtUtils::Embed -e ldopts -- DynaLoader This will print arguments for linking with just the B extension and B. perl -MExtUtils::Embed -e ldopts -- -std Msql -- -L/usr/msql/lib -lmsql Any arguments after the second '--' token are additional linker arguments that will be examined for potential conflict. If there is no conflict, the additional arguments will be part of the output. =item perl_inc() For including perl header files this function simply prints: -I $Config{archlib}/CORE So, rather than having to say: perl -MConfig -e 'print "-I $Config{archlib}/CORE"' Just say: perl -MExtUtils::Embed -e perl_inc =item ccflags(), ccdlflags() These functions simply print $Config{ccflags} and $Config{ccdlflags} =item ccopts() This function combines perl_inc(), ccflags() and ccdlflags() into one. =item xsi_header() This function simply returns a string defining the same B macro as B along with #including B and B. =item xsi_protos(@modules) This function returns a string of B prototypes for each @modules. =item xsi_body(@modules) This function returns a string of calls to B that glue the module B function to B for each @modules. B uses the xsi_* functions to generate most of it's code. =head1 EXAMPLES For examples on how to use B for building C/C++ applications with embedded perl, see the eg/ directory and the I man page. =head1 SEE ALSO the I man page =head1 AUTHOR Doug MacEachern Based on ideas from Tim Bunce and B by Andreas Koenig and Tim Bunce. =cut nvi-1.81.6/dist/INSTALL0100644000076400001440000001722710720065506013457 0ustar skimousersBasic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. nvi-1.81.6/dist/Makefile.am0100644000076400001440000003067210720065506014461 0ustar skimousersvisrcdir= @srcdir@/..

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

A .I text editor .R is a program that assists you as you create and modify text. The text editor you will learn here is named .I edit. Creating text using edit is as easy as typing it on an electric typewriter. Modifying text involves telling the text editor what you want to add, change, or delete. You can review your text by typing a command to print the file contents as they are currently. Another program (which we do not discuss in this document), a text formatter, rearranges your text for you into ``finished form.'' .PP These lessons assume no prior familiarity with computers or with text editing. They consist of a series of text editing sessions which lead you through the fundamental steps of creating and revising text. After scanning each lesson and before beginning the next, you should try the examples at a terminal to get a feeling for the actual process of text editing. If you set aside some time for experimentation, you will soon become familiar with using the computer to write and modify text. In addition to the actual use of the text editor, other features of \s-2UNIX\s0 will be very important to your work. You can begin to learn about these other features by reading one of the other tutorials that provide a general introduction to the system. You will be ready to proceed with this lesson as soon as you are familiar with (1) your terminal and its special keys, (2) how to login, (3) and the ways of correcting typing errors. Let's first define some terms: .sp .5 .IP program 12 A set of instructions, given to the computer, describing the sequence of steps the computer performs in order to accomplish a specific task. The task must be specific, such as balancing your checkbook or editing your text. A general task, such as working for world peace, is something we can all do, but not something we can currently write programs to do. .IP UNIX \s-2UNIX\s0 is a special type of program, called an operating system, that supervises the machinery and all other programs comprising the total computer system. .IP edit .I edit is the name of the \s-2UNIX\s0 text editor you will be learning to use, and is a program that aids you in writing or revising text. Edit was designed for beginning users, and is a simplified version of an editor named .I ex. .IP file Each \s-2UNIX\s0 account is allotted space for the permanent storage of information, such as programs, data or text. A file is a logical unit of data, for example, an essay, a program, or a chapter from a book, which is stored on a computer system. Once you create a file, it is kept until you instruct the system to remove it. You may create a file during one \s-2UNIX\s0 session, end the session, and return to use it at a later time. Files contain anything you choose to write and store in them. The sizes of files vary to suit your needs; one file might hold only a single number, yet another might contain a very long document or program. The only way to save information from one session to the next is to store it in a file, which you will learn in Session 1. .IP filename Filenames are used to distinguish one file from another, serving the same purpose as the labels of manila folders in a file cabinet. In order to write or access information in a file, you use the name of that file in a \s-2UNIX\s0 command, and the system will automatically locate the file. .IP disk Files are stored on an input/output device called a disk, which looks something like a stack of phonograph records. Each surface is coated with a material similar to that on magnetic recording tape, and information is recorded on it. .IP buffer A temporary work space, made available to the user for the duration of a session of text editing and used for creating and modifying the text file. We can think of the buffer as a blackboard that is erased after each class, where each session with the editor is a class. .bp .SH .ce 1 \s+2Session 1\s0 .sp 1 .SH Making contact with \s-1UNIX\s0 .PP To use the editor you must first make contact with the computer by logging in to \s-2UNIX\s0. We'll quickly review the standard \s-2UNIX\s0 login procedure for the two ways you can make contact: on a terminal that is directly linked to the computer, or over a telephone line where the computer answers your call. .SH Directly-linked terminals .PP Turn on your terminal and press the \s-1RETURN\s0 key. You are now ready to login. .SH Dial-up terminals .PP If your terminal connects with the computer over a telephone line, turn on the terminal, dial the system access number, and, when you hear a high-pitched tone, place the telephone handset in the acoustic coupler, if you are using one. You are now ready to login. .SH Logging in .PP The message inviting you to login is: .DS I 1i login: .DE .LP Type your login name, which identifies you to \s-2UNIX\s0, on the same line as the login message, and press \s-2RETURN\s+2. If the terminal you are using has both upper and lower case, .B be sure you enter your login name in lower case; .R otherwise \s-2UNIX\s0 assumes your terminal has only upper case and will not recognize lower case letters you may type. \s-2UNIX\s0 types ``login:'' and you reply with your login name, for example ``susan'': .DS I 1i login: \fBsusan\fR \fI(and press the \s-2RETURN\s0 key)\fR .DE (In the examples, input you would type appears in .B "bold face" to distinguish it from the responses from \s-2UNIX\s0.) .PP \s-2UNIX\s0 will next respond with a request for a password as an additional precaution to prevent unauthorized people from using your account. The password will not appear when you type it, to prevent others from seeing it. The message is: .DS I 1i Password: \fI(type your password and press \s-2RETURN\s+2)\fR .DE If any of the information you gave during the login sequence was mistyped or incorrect, \s-2UNIX\s0 will respond with .DS I 1i Login incorrect. .if t .sp .2v .if n .sp 1 login: .DE in which case you should start the login process anew. Assuming that you have successfully logged in, \s-2UNIX\s0 will print the message of the day and eventually will present you with a % at the beginning of a fresh line. The % is the \s-2UNIX\s0 prompt symbol which tells you that \s-2UNIX\s0 is ready to accept a command. .bd I 3 .SH Asking for \fIedit\fP .fl .bd I .PP You are ready to tell \s-2UNIX\s0 that you want to work with edit, the text editor. Now is a convenient time to choose a name for the file of text you are about to create. To begin your editing session, type .B edit followed by a space and then the filename you have selected; for example, ``text''. After that, press the \s-2RETURN\s0 key and wait for edit's response: .DS I 1i % \fBedit text\fP \fI(followed by a \s-2RETURN\s+2)\fR "text" No such file or directory : .DE If you typed the command correctly, you will now be in communication with edit. Edit has set aside a buffer for use as a temporary working space during your current editing session. Since ``text'' is a new file we are about to create the editor was unable to find that file, which it confirms by saying: .DS I 1i "text" No such file or directory .DE On the next line appears edit's prompt ``:'', announcing that you are in \f2command mode\f1 and edit expects a command from you. You may now begin to create the new file. .SH The ``Command not found'' message .PP If you misspelled edit by typing, say, ``editor'', this might appear: .DS I 1i % \fBeditor\fP editor: Command not found % .DE Your mistake in calling edit ``editor'' was treated by \s-2UNIX\s0 as a request for a program named ``editor''. Since there is no program named ``editor'', \s-2UNIX\s0 reported that the program was ``not found''. A new % indicates that \s-2UNIX\s0 is ready for another command, and you may then enter the correct command. .SH A summary .PP Your exchange with \s-2UNIX\s0 as you logged in and made contact with edit should look something like this: .DS I 1i login: \fBsusan\fP Password: \&... A Message of General Interest ... % \fBedit text\fP "text" No such file or directory : .DE .SH Entering text .PP You may now begin entering text into the buffer. This is done by \fIappending\fP (or adding) text to whatever is currently in the buffer. Since there is nothing in the buffer at the moment, you are appending text to nothing; in effect, since you are adding text to nothing you are creating text. Most edit commands have two equivalent forms: a word that suggests what the command does, and a shorter abbreviation of that word. Many beginners find the full command names easier to remember at first, but once you are familiar with editing you may prefer to type the shorter abbreviations. The command to input text is ``append''. (It may be abbreviated ``a''.) Type .B append and press the \s-2RETURN\s0 key. .DS I 1i % \fBedit text \fR:\|\fBappend .R .DE .SH .bd I 3 Messages from .I edit .fl .bd I .PP If you make a mistake in entering a command and type something that edit does not recognize, edit will respond with a message intended to help you diagnose your error. For example, if you misspell the command to input text by typing, perhaps, ``add'' instead of ``append'' or ``a'', you will receive this message: .DS I 1i :\|\fBadd\fR add: Not an editor command : .DE When you receive a diagnostic message, check what you typed in order to determine what part of your command confused edit. The message above means that edit was unable to recognize your mistyped command and, therefore, did not execute it. Instead, a new ``:'' appeared to let you know that edit is again ready to execute a command. .SH Text input mode .PP By giving the command ``append'' (or using the abbreviation ``a''), you entered .I text input mode, .R also known as .I append mode. .R When you enter text input mode, edit stops sending you a prompt. You will not receive any prompts or error messages while in text input mode. You can enter pretty much anything you want on the lines. The lines are transmitted one by one to the buffer and held there during the editing session. You may append as much text as you want, and .I when you wish to stop entering text lines you should type a period as the only character on the line and press the \s-2RETURN\s0 key. .R When you type the period and press \s-2RETURN\s0, you signal that you want to stop appending text, and edit responds by allowing you to exit text input mode and reenter command mode. Edit will again prompt you for a command by printing ``:''. .PP Leaving append mode does not destroy the text in the buffer. You have to leave append mode to do any of the other kinds of editing, such as changing, adding, or printing text. If you type a period as the first character and type any other character on the same line, edit will believe you want to remain in append mode and will not let you out. As this can be very frustrating, be sure to type .B only the period and the \s-2RETURN\s0 key. .PP This is a good place to learn an important lesson about computers and text: a blank space is a character as far as a computer is concerned. If you so much as type a period followed by a blank (that is, type a period and then the space bar on the keyboard), you will remain in append mode with the last line of text being: .DS I 1i .B .ps +2 \&. .ps -2 .R .DE Let's say that you enter the lines (try to type .B exactly what you see, including ``thiss''): .DS I 1i .B This is some sample text. And thiss is some more text. Text editing is strange, but nice. \&. .R .DE The last line is the period followed by a \s-2RETURN\s0 that gets you out of append mode. .SH Making corrections .PP If you have read a general introduction to \s-2UNIX\s0, you will recall that it is possible to erase individual letters that you have typed. This is done by typing the designated erase character as many times as there are characters you want to erase. .PP The usual erase character varies from place to place and user to user. Often it is the backspace (control-H), so you can correct typing errors in the line you are typing by holding down the \s-1CTRL\s+1 key and typing the ``H'' key. (Sometimes it is the DEL key.) If you type the erase character you will notice that the terminal backspaces in the line you are on. You can backspace over your error, and then type what you want to be the rest of the line. .PP If you make a bad start in a line and would like to begin again, you can either backspace to the beginning of the line or you can use the at-sign ``@'' to erase everything on the line: .DS I 1i .B Text edtiing is strange, but@ Text editing is strange, but nice. .R .fl .bd S .DE When you type the at-sign (@), you erase the entire line typed so far and are given a fresh line to type on. You may immediately begin to retype the line. This, unfortunately, does not work after you type the line and press \s-2RETURN\s+2. To make corrections in lines that have been completed, it is necessary to use the editing commands covered in the next sessions. .SH Writing text to disk .PP You are now ready to edit the text. One common operation is to write the text to disk as a file for safekeeping after the session is over. This is the only way to save information from one session to the next, since the editor's buffer is temporary and will last only until the end of the editing session. Learning how to write a file to disk is second in importance only to entering the text. To write the contents of the buffer to a disk file, use the command ``write'' (or its abbreviation ``w''): .DS I 1i :\|\fBwrite .R .DE Edit will copy the contents of the buffer to a disk file. If the file does not yet exist, a new file will be created automatically and the presence of a ``[New file]'' will be noted. The newly-created file will be given the name specified when you entered the editor, in this case ``text''. To confirm that the disk file has been successfully written, edit will repeat the filename and give the number of lines and the total number of characters in the file. The buffer remains unchanged by the ``write'' command. All of the lines that were written to disk will still be in the buffer, should you want to modify or add to them. .PP Edit must have a name for the file to be written. If you forgot to indicate the name of the file when you began to edit, edit will print in response to your write command: .DS I 1i No current filename .DE If this happens, you can specify the filename in a new write command: .DS I 1i :\|\fBwrite text .R .DE After the ``write'' (or ``w''), type a space and then the name of the file. .SH Signing off .PP We have done enough for this first lesson on using the \s-2UNIX\s0 text editor, and are ready to quit the session with edit. To do this we type ``quit'' (or ``q'') and press \s-2RETURN\s+2: .DS I 1i :\|\fBwrite .R "text" [New file] 3 lines, 90 characters :\|\fBquit\fR % .DE The % is from \s-2UNIX\s0 to tell you that your session with edit is over and you may command \s-2UNIX\s0 further. Since we want to end the entire session at the terminal, we also need to exit from \s-2UNIX\s0. In response to the \s-2UNIX\s0 prompt of ``\|%\|'' type the command .DS I 1i %\|\fBlogout\fR .DE This will end your session with \s-2UNIX\s0, and will ready the terminal for the next user. It is always important to type \fBlogout\fR at the end of a session to make absolutely sure no one could accidentally stumble into your abandoned session and thus gain access to your files, tempting even the most honest of souls. .sp 1 .PP This is the end of the first session on \s-2UNIX\s0 text editing. .bp .TL Session 2 .sp .PP Login with \s-2UNIX\s0 as in the first session: .DS I 1i login: \fBsusan\fP \fI(carriage return)\fR Password: \fI(give password and carriage return)\fR .if t .sp .2v .if n .sp 1 \&... A Message of General Interest ... % .DE When you indicate you want to edit, you can specify the name of the file you worked on last time. This will start edit working, and it will fetch the contents of the file into the buffer, so that you can resume editing the same file. When edit has copied the file into the buffer, it will repeat its name and tell you the number of lines and characters it contains. Thus, .DS I 1i .B % edit text .R "text" 3 lines, 90 characters : .DE means you asked edit to fetch the file named ``text'' for editing, causing it to copy the 90 characters of text into the buffer. Edit awaits your further instructions, and indicates this by its prompt character, the colon (:). In this session, we will append more text to our file, print the contents of the buffer, and learn to change the text of a line. .SH Adding more text to the file .PP If you want to add more to the end of your text you may do so by using the append command to enter text input mode. When ``append'' is the first command of your editing session, the lines you enter are placed at the end of the buffer. Here we'll use the abbreviation for the append command, ``a'': .DS I 1i :\|\fBa This is text added in Session 2. It doesn't mean much here, but it does illustrate the editor. \|\fB\s+2\&.\s-2 .R .DE You may recall that once you enter append mode using the ``a'' (or ``append'') command, you need to type a line containing only a period (.) to exit append mode. .SH Interrupt .PP Should you press the \s-2RUB\s+2 key (sometimes labelled \s-2DELETE\s+2) while working with edit, it will send this message to you: .DS I 1i Interrupt : .DE Any command that edit might be executing is terminated by rub or delete, causing edit to prompt you for a new command. If you are appending text at the time, you will exit from append mode and be expected to give another command. The line of text you were typing when the append command was interrupted will not be entered into the buffer. .SH Making corrections .PP If while typing the line you hit an incorrect key, recall that you may delete the incorrect character or cancel the entire line of input by erasing in the usual way. Refer either to the last few pages of Session 1 if you need to review the procedures for making a correction. The most important idea to remember is that erasing a character or cancelling a line must be done before you press the \s-2RETURN\s+2 key. .SH Listing what's in the buffer (p) .PP Having appended text to what you wrote in Session 1, you might want to see all the lines in the buffer. To print the contents of the buffer, type the command: .DS I 1i :\|\fB1,$p .R .DE The ``1''\(dg .FS \(dgThe numeral ``one'' is the top left-most key, and should not be confused with the letter ``el''. .FE stands for line 1 of the buffer, the ``$'' is a special symbol designating the last line of the buffer, and ``p'' (or \fBprint\fR) is the command to print from line 1 to the end of the buffer. The command ``1,$p'' gives you: .DS I 1i This is some sample text. And thiss is some more text. Text editing is strange, but nice. This is text added in Session 2. It doesn't mean much here, but it does illustrate the editor. .DE Occasionally, you may accidentally type a character that can't be printed, which can be done by striking a key while the \s-2CTRL\s0 key is pressed. In printing lines, edit uses a special notation to show the existence of non-printing characters. Suppose you had introduced the non-printing character ``control-A'' into the word ``illustrate'' by accidently pressing the \s-2CTRL\s0 key while typing ``a''. This can happen on many terminals because the \s-2CTRL\s+2 key and the ``A'' key are beside each other. If your finger presses between the two keys, control-A results. When asked to print the contents of the buffer, edit would display .DS I 1i it does illustr^Ate the editor. .DE To represent the control-A, edit shows ``^A''. The sequence ``^'' followed by a capital letter stands for the one character entered by holding down the \s-2CTRL\s0 key and typing the letter which appears after the ``^''. We'll soon discuss the commands that can be used to correct this typing error. .PP In looking over the text we see that ``this'' is typed as ``thiss'' in the second line, a deliberate error so we can learn to make corrections. Let's correct the spelling. .SH Finding things in the buffer .PP In order to change something in the buffer we first need to find it. We can find ``thiss'' in the text we have entered by looking at a listing of the lines. Physically speaking, we search the lines of text looking for ``thiss'' and stop searching when we have found it. The way to tell edit to search for something is to type it inside slash marks: .DS I 1i :\|\fB/thiss/ .R .DE By typing .B /thiss/ and pressing \s-1RETURN\s0, you instruct edit to search for ``thiss''. If you ask edit to look for a pattern of characters which it cannot find in the buffer, it will respond ``Pattern not found''. When edit finds the characters ``thiss'', it will print the line of text for your inspection: .DS I 1i And thiss is some more text. .DE Edit is now positioned in the buffer at the line it just printed, ready to make a change in the line. .bp .SH The current line .PP Edit keeps track of the line in the buffer where it is located at all times during an editing session. In general, the line that has been most recently printed, entered, or changed is the current location in the buffer. The editor is prepared to make changes at the current location in the buffer, unless you direct it to another location. .PP In particular, when you bring a file into the buffer, you will be located at the last line in the file, where the editor left off copying the lines from the file to the buffer. If your first editing command is ``append'', the lines you enter are added to the end of the file, after the current line \(em the last line in the file. .PP You can refer to your current location in the buffer by the symbol period (.) usually known by the name ``dot''. If you type ``.'' and carriage return you will be instructing edit to print the current line: .DS I 1i :\|\fB\s+2\&.\s-2 .R And thiss is some more text. .DE .PP If you want to know the number of the current line, you can type .B \&.= and press \s-2RETURN\s+2, and edit will respond with the line number: .DS I 1i :\|\fB\s+2.\s-2= .R 2 .DE If you type the number of any line and press \s-2RETURN\s+2, edit will position you at that line and print its contents: .DS I 1i :\|\fB2 .R And thiss is some more text. .DE You should experiment with these commands to gain experience in using them to make changes. .SH Numbering lines (nu) .PP The .B number (nu) .R command is similar to print, giving both the number and the text of each printed line. To see the number and the text of the current line type .DS I 1i :\|\fBnu .R \0\0\0\0\02\0\0And thiss is some more text. .DE Note that the shortest abbreviation for the number command is ``nu'' (and not ``n'', which is used for a different command). You may specify a range of lines to be listed by the number command in the same way that lines are specified for print. For example, \f31,$nu\f1 lists all lines in the buffer with their corresponding line numbers. .SH Substitute command (s) .PP Now that you have found the misspelled word, you can change it from ``thiss'' to ``this''. As far as edit is concerned, changing things is a matter of substituting one thing for another. As .I a stood for .I append, so .I s stands for .I substitute. We will use the abbreviation ``s'' to reduce the chance of mistyping the substitute command. This command will instruct edit to make the change: .DS I 1i \f32s/thiss/this/\f1 .DE We first indicate the line to be changed, line 2, and then type an ``s'' to indicate we want edit to make a substitution. Inside the first set of slashes are the characters that we want to change, followed by the characters to replace them, and then a closing slash mark. To summarize: .DS I 1i 2s/ \fIwhat is to be changed\fR / \fIwhat to change it to \fR/ .DE If edit finds an exact match of the characters to be changed it will make the change .B only in the first occurrence of the characters. If it does not find the characters to be changed, it will respond: .DS I 1i Substitute pattern match failed .DE indicating that your instructions could not be carried out. When edit does find the characters that you want to change, it will make the substitution and automatically print the changed line, so that you can check that the correct substitution was made. In the example, .DS I 1i :\|\fB2s/thiss/this/ .R And this is some more text. .DE line 2 (and line 2 only) will be searched for the characters ``thiss'', and when the first exact match is found, ``thiss'' will be changed to ``this''. Strictly speaking, it was not necessary above to specify the number of the line to be changed. In .DS I 1i :\|\fBs/thiss/this/ .R .DE edit will assume that we mean to change the line where we are currently located (``.''). In this case, the command without a line number would have produced the same result because we were already located at the line we wished to change. .PP For another illustration of the substitute command, let us choose the line: .DS I 1i Text editing is strange, but nice. .DE You can make this line a bit more positive by taking out the characters ``strange, but\ '' so the line reads: .DS I 1i Text editing is nice. .DE A command that will first position edit at the desired line and then make the substitution is: .DS I 1i :\|\fB/strange/s/strange, but // .R .DE .LP What we have done here is combine our search with our substitution. Such combinations are perfectly legal, and speed up editing quite a bit once you get used to them. That is, you do not necessarily have to use line numbers to identify a line to edit. Instead, you may identify the line you want to change by asking edit to search for a specified pattern of letters that occurs in that line. The parts of the above command are: .in +1i .TS l l. \fB/strange/\fP tells edit to find the characters ``strange'' in the text \fBs\fP tells edit to make a substitution \fB/strange, but //\fP substitutes nothing at all for the characters ``strange, but '' .TE .in -1i .PP You should note the space after ``but'' in ``/strange, but /''. If you do not indicate that the space is to be taken out, your line will read: .DS I 1i .if t Text editing is nice. .if n Text editing is nice. .DE which looks a little funny because of the extra space between ``is'' and ``nice''. Again, we realize from this that a blank space is a real character to a computer, and in editing text we need to be aware of spaces within a line just as we would be aware of an ``a'' or a ``4''. .SH Another way to list what's in the buffer (z) .PP Although the print command is useful for looking at specific lines in the buffer, other commands may be more convenient for viewing large sections of text. You can ask to see a screen full of text at a time by using the command .B z. If you type .DS I 1i :\|\fB1z .R .DE edit will start with line 1 and continue printing lines, stopping either when the screen of your terminal is full or when the last line in the buffer has been printed. If you want to read the next segment of text, type the command .DS I 1i :\|\fBz .DE If no starting line number is given for the z command, printing will start at the ``current'' line, in this case the last line printed. Viewing lines in the buffer one screen full at a time is known as \fIpaging\fR. Paging can also be used to print a section of text on a hard-copy terminal. .SH Saving the modified text .PP This seems to be a good place to pause in our work, and so we should end the second session. If you (in haste) type ``q'' to quit the session your dialogue with edit will be: .DS I 1i :\|\fBq .R No write since last change (:quit! overrides) : .DE This is edit's warning that you have not written the modified contents of the buffer to disk. You run the risk of losing the work you did during the editing session since you typed the latest write command. Because in this lesson we have not written to disk at all, everything we have done would have been lost if edit had obeyed the \fBq\fR command. If you did not want to save the work done during this editing session, you would have to type ``q!'' or (``quit!'') to confirm that you indeed wanted to end the session immediately, leaving the file as it was after the most recent ``write'' command. However, since you want to save what you have edited, you need to type: .DS I 1i :\|\fBw .R "text" 6 lines, 171 characters .DE and then follow with the commands to quit and logout: .DS I 1i :\|\fBq % \fBlogout\fR .DE and hang up the phone or turn off the terminal when \s-2UNIX\s0 asks for a name. Terminals connected to the port selector will stop after the logout command, and pressing keys on the keyboard will do nothing. .sp 1 .PP This is the end of the second session on \s-2UNIX\s0 text editing. .bp .TL Session 3 .SH Bringing text into the buffer (e) .PP Login to \s-2UNIX\s0 and make contact with edit. You should try to login without looking at the notes, but if you must then by all means do. .PP Did you remember to give the name of the file you wanted to edit? That is, did you type .DS I 1i % \fBedit text\fR .DE or simply .DS I 1i % \fBedit\fR .DE Both ways get you in contact with edit, but the first way will bring a copy of the file named ``text'' into the buffer. If you did forget to tell edit the name of your file, you can get it into the buffer by typing: .DS I 1i :\|\fBe text .R "text" 6 lines, 171 characters .DE The command .B edit, which may be abbreviated \fBe\fR, tells edit that you want to erase anything that might already be in the buffer and bring a copy of the file ``text'' into the buffer for editing. You may also use the edit (e) command to change files in the middle of an editing session, or to give edit the name of a new file that you want to create. Because the edit command clears the buffer, you will receive a warning if you try to edit a new file without having saved a copy of the old file. This gives you a chance to write the contents of the buffer to disk before editing the next file. .SH Moving text in the buffer (m) .PP Edit allows you to move lines of text from one location in the buffer to another by means of the .B move (\fBm\fR) command. The first two examples are for illustration only, though after you have read this Session you are welcome to return to them for practice. The command .DS I 1i :\|\fB2,4m$ .R .DE directs edit to move lines 2, 3, and 4 to the end of the buffer ($). The format for the move command is that you specify the first line to be moved, the last line to be moved, the move command ``m'', and the line after which the moved text is to be placed. So, .DS I 1i :\|\fB1,3m6 .R .DE would instruct edit to move lines 1 through 3 (inclusive) to a location after line 6 in the buffer. To move only one line, say, line 4, to a location in the buffer after line 5, the command would be ``4m5''. .PP Let's move some text using the command: .DS I 1i :\|\fB5,$m1 .R 2 lines moved it does illustrate the editor. .DE After executing a command that moves more than one line of the buffer, edit tells how many lines were affected by the move and prints the last moved line for your inspection. If you want to see more than just the last line, you can then use the print (p), z, or number (nu) command to view more text. The buffer should now contain: .DS I 1i This is some sample text. It doesn't mean much here, but it does illustrate the editor. And this is some more text. Text editing is nice. This is text added in Session 2. .DE You can restore the original order by typing: .DS I 1i :\|\fB4,$m1 .R .DE or, combining context searching and the move command: .DS I 1i :\|\fB/And this is some/,/This is text/m/This is some sample/ .R .DE (Do not type both examples here!) The problem with combining context searching with the move command is that your chance of making a typing error in such a long command is greater than if you type line numbers. .SH Copying lines (copy) .PP The .B copy command is used to make a second copy of specified lines, leaving the original lines where they were. Copy has the same format as the move command, for example: .DS I 1i :\|\fB2,5copy $ .R .DE makes a copy of lines 2 through 5, placing the added lines after the buffer's end ($). Experiment with the copy command so that you can become familiar with how it works. Note that the shortest abbreviation for copy is \f3co\f1 (and not the letter ``c'', which has another meaning). .SH Deleting lines (d) .PP Suppose you want to delete the line .DS I 1i This is text added in Session 2. .DE from the buffer. If you know the number of the line to be deleted, you can type that number followed by \fBdelete\fR or \fBd\fR. This example deletes line 4, which is ``This is text added in Session 2.'' if you typed the commands suggested so far. .DS I 1i :\|\fB4d .R It doesn't mean much here, but .DE Here ``4'' is the number of the line to be deleted, and ``delete'' or ``d'' is the command to delete the line. After executing the delete command, edit prints the line that has become the current line (``.''). .PP If you do not happen to know the line number you can search for the line and then delete it using this sequence of commands: .DS I 1i :\|\fB/added in Session 2./ .R This is text added in Session 2. :\|\fBd .R It doesn't mean much here, but .DE The ``/added in Session 2./'' asks edit to locate and print the line containing the indicated text, starting its search at the current line and moving line by line until it finds the text. Once you are sure that you have correctly specified the line you want to delete, you can enter the delete (d) command. In this case it is not necessary to specify a line number before the ``d''. If no line number is given, edit deletes the current line (``.''), that is, the line found by our search. After the deletion, your buffer should contain: .DS I 1i This is some sample text. And this is some more text. Text editing is nice. It doesn't mean much here, but it does illustrate the editor. And this is some more text. Text editing is nice. This is text added in Session 2. It doesn't mean much here, but .DE To delete both lines 2 and 3: .DS I 1i And this is some more text. Text editing is nice. .DE you type .DS I 1i :\|\f32,3d\f1 2 lines deleted .DE which specifies the range of lines from 2 to 3, and the operation on those lines \(em ``d'' for delete. If you delete more than one line you will receive a message telling you the number of lines deleted, as indicated in the example above. .PP The previous example assumes that you know the line numbers for the lines to be deleted. If you do not you might combine the search command with the delete command: .DS I 1i :\|\fB/And this is some/,/Text editing is nice./d .R .DE .SH A word or two of caution .PP In using the search function to locate lines to be deleted you should be .B absolutely sure .R the characters you give as the basis for the search will take edit to the line you want deleted. Edit will search for the first occurrence of the characters starting from where you last edited \- that is, from the line you see printed if you type dot (.). .PP A search based on too few characters may result in the wrong lines being deleted, which edit will do as easily as if you had meant it. For this reason, it is usually safer to specify the search and then delete in two separate steps, at least until you become familiar enough with using the editor that you understand how best to specify searches. For a beginner it is not a bad idea to double-check each command before pressing \s-2RETURN\s+2 to send the command on its way. .SH Undo (u) to the rescue .PP The .B undo (u) .R command has the ability to reverse the effects of the last command that changed the buffer. To undo the previous command, type ``u'' or ``undo''. Undo can rescue the contents of the buffer from many an unfortunate mistake. However, its powers are not unlimited, so it is still wise to be reasonably careful about the commands you give. .PP It is possible to undo only commands which have the power to change the buffer \(em for example, delete, append, move, copy, substitute, and even undo itself. The commands write (w) and edit (e), which interact with disk files, cannot be undone, nor can commands that do not change the buffer, such as print. Most importantly, the .B only command that can be reversed by undo is the last ``undo-able'' command you typed. You can use control-H and @ to change commands while you are typing them, and undo to reverse the effect of the commands after you have typed them and pressed \s-2RETURN\s+2. .PP To illustrate, let's issue an undo command. Recall that the last buffer-changing command we gave deleted the lines formerly numbered 2 and 3. Typing undo at this moment will reverse the effects of the deletion, causing those two lines to be replaced in the buffer. .DS I 1i :\|\fBu .R 2 more lines in file after undo And this is some more text. .DE Here again, edit informs you if the command affects more than one line, and prints the text of the line which is now ``dot'' (the current line). .SH More about the dot (.) and buffer end ($) .PP The function assumed by the symbol dot depends on its context. It can be used: .IP 1. to exit from append mode; we type dot (and only a dot) on a line and press \s-2RETURN\s+2; .IP 2. to refer to the line we are at in the buffer. .LP Dot can also be combined with the equal sign to get the number of the line currently being edited: .DS I 1i :\|\fB\&.= .R .DE If we type ``\fB.\fR='' we are asking for the number of the line, and if we type ``\fB.\fR'' we are asking for the text of the line. .PP In this editing session and the last, we used the dollar sign to indicate the end of the buffer in commands such as print, copy, and move. The dollar sign as a command asks edit to print the last line in the buffer. If the dollar sign is combined with the equal sign (\f3$=\f1) edit will print the line number corresponding to the last line in the buffer. .PP ``\fB.\fR'' and ``$'', then, represent line numbers. Whenever appropriate, these symbols can be used in place of line numbers in commands. For example .DS I 1i :\|\fB\s+2.\s-2,$d .R .DE instructs edit to delete all lines from the current line (\fB.\fR) to the end of the buffer. .SH Moving around in the buffer (+ and \-) .PP When you are editing you often want to go back and re-read a previous line. You could specify a context search for a line you want to read if you remember some of its text, but if you simply want to see what was written a few, say 3, lines ago, you can type .DS I 1i \-3p .DE This tells edit to move back to a position 3 lines before the current line (.) and print that line. You can move forward in the buffer similarly: .DS I 1i +2p .DE instructs edit to print the line that is 2 ahead of your current position. .PP You may use ``+'' and ``\-'' in any command where edit accepts line numbers. Line numbers specified with ``+'' or ``\-'' can be combined to print a range of lines. The command .DS I 1i :\|\fB\-1,+2copy$ .R .DE makes a copy of 4 lines: the current line, the line before it, and the two after it. The copied lines will be placed after the last line in the buffer ($), and the original lines referred to by ``\-1'' and ``+2'' remain where they are. .PP Try typing only ``\-''; you will move back one line just as if you had typed ``\-1p''. Typing the command ``+'' works similarly. You might also try typing a few plus or minus signs in a row (such as ``+++'') to see edit's response. Typing \s-2RETURN\s+2 alone on a line is the equivalent of typing ``+1p''; it will move you one line ahead in the buffer and print that line. .PP If you are at the last line of the buffer and try to move further ahead, perhaps by typing a ``+'' or a carriage return alone on the line, edit will remind you that you are at the end of the buffer: .sp .nf .ti 1i At end-of-file .br or .ti 1i Not that many lines in buffer .fi .LP Similarly, if you try to move to a position before the first line, edit will print one of these messages: .sp .nf .ti 1i Nonzero address required on this command .br or .ti 1i Negative address \- first buffer line is 1 .fi .LP The number associated with a buffer line is the line's ``address'', in that it can be used to locate the line. .SH Changing lines (c) .PP You can also delete certain lines and insert new text in their place. This can be accomplished easily with the .B "change (c)" command. The change command instructs edit to delete specified lines and then switch to text input mode to accept the text that will replace them. Let's say you want to change the first two lines in the buffer: .DS I 1i This is some sample text. And this is some more text. .DE to read .DS I 1i This text was created with the \s-2UNIX\s0 text editor. .DE To do so, you type: .DS I 1i :\|\fB1,2c .R 2 lines changed .B This text was created with the \s-2UNIX\s0 text editor. \s+2\&.\s-2 .R : .DE In the command .B 1,2c we specify that we want to change the range of lines beginning with 1 and ending with 2 by giving line numbers as with the print command. These lines will be deleted. After you type \s-2RETURN\s+2 to end the change command, edit notifies you if more than one line will be changed and places you in text input mode. Any text typed on the following lines will be inserted into the position where lines were deleted by the change command. .B You will remain in text input mode until you exit in the usual way, by typing a period alone on a line. .R Note that the number of lines added to the buffer need not be the same as the number of lines deleted. .sp 1 .PP This is the end of the third session on text editing with \s-2UNIX\s0. .bp .SH .ce 1 \s+2Session 4\s0 .sp .PP This lesson covers several topics, starting with commands that apply throughout the buffer, characters with special meanings, and how to issue \s-2UNIX\s0 commands while in the editor. The next topics deal with files: more on reading and writing, and methods of recovering files lost in a crash. The final section suggests sources of further information. .SH Making commands global (g) .PP One disadvantage to the commands we have used for searching or substituting is that if you have a number of instances of a word to change it appears that you have to type the command repeatedly, once for each time the change needs to be made. Edit, however, provides a way to make commands apply to the entire contents of the buffer \- the .B global (g) .R command. .PP To print all lines containing a certain sequence of characters (say, ``text'') the command is: .DS I 1i :\|\fBg/text/p .R .DE The ``g'' instructs edit to make a global search for all lines in the buffer containing the characters ``text''. The ``p'' prints the lines found. .PP To issue a global command, start by typing a ``g'' and then a search pattern identifying the lines to be affected. Then, on the same line, type the command to be executed for the identified lines. Global substitutions are frequently useful. For example, to change all instances of the word ``text'' to the word ``material'' the command would be a combination of the global search and the substitute command: .DS I 1i :\|\fBg/text/s/text/material/g .R .DE Note the ``g'' at the end of the global command, which instructs edit to change each and every instance of ``text'' to ``material''. If you do not type the ``g'' at the end of the command only the .I first instance of ``text'' \fIin each line\fR will be changed (the normal result of the substitute command). The ``g'' at the end of the command is independent of the ``g'' at the beginning. You may give a command such as: .DS I 1i :\|\fB5s/text/material/g .R .DE to change every instance of ``text'' in line 5 alone. Further, neither command will change ``text'' to ``material'' if ``Text'' begins with a capital rather than a lower-case .I t. .PP Edit does not automatically print the lines modified by a global command. If you want the lines to be printed, type a ``p'' at the end of the global command: .DS I 1i :\|\fBg/text/s/text/material/gp .R .DE You should be careful about using the global command in combination with any other \- in essence, be sure of what you are telling edit to do to the entire buffer. For example, .DS I 1i :\|\fBg/ /d .R 72 less lines in file after global .DE will delete every line containing a blank anywhere in it. This could adversely affect your document, since most lines have spaces between words and thus would be deleted. After executing the global command, edit will print a warning if the command added or deleted more than one line. Fortunately, the undo command can reverse the effects of a global command. You should experiment with the global command on a small file of text to see what it can do for you. .SH More about searching and substituting .PP In using slashes to identify a character string that we want to search for or change, we have always specified the exact characters. There is a less tedious way to repeat the same string of characters. To change ``text'' to ``texts'' we may type either .DS I 1i :\|\fB/text/s/text/texts/ .R .DE as we have done in the past, or a somewhat abbreviated command: .DS I 1i :\|\fB/text/s//texts/ .R .DE In this example, the characters to be changed are not specified \- there are no characters, not even a space, between the two slash marks that indicate what is to be changed. This lack of characters between the slashes is taken by the editor to mean ``use the characters we last searched for as the characters to be changed.'' .PP Similarly, the last context search may be repeated by typing a pair of slashes with nothing between them: .DS I 1i :\|\fB/does/ .R It doesn't mean much here, but :\|\fB// .R it does illustrate the editor. .DE (You should note that the search command found the characters ``does'' in the word ``doesn't'' in the first search request.) Because no characters are specified for the second search, the editor scans the buffer for the next occurrence of the characters ``does''. .PP Edit normally searches forward through the buffer, wrapping around from the end of the buffer to the beginning, until the specified character string is found. If you want to search in the reverse direction, use question marks (?) instead of slashes to surround the characters you are searching for. .PP It is also possible to repeat the last substitution without having to retype the entire command. An ampersand (&) used as a command repeats the most recent substitute command, using the same search and replacement patterns. After altering the current line by typing .DS I 1i :\|\fBs/text/texts/ .R .DE you type .DS I 1i :\|\fB/text/& .R .DE or simply .DS I 1i :\|\fB//& .R .DE to make the same change on the next line in the buffer containing the characters ``text''. .SH Special characters .PP Two characters have special meanings when used in specifying searches: ``$'' and ``^''. ``$'' is taken by the editor to mean ``end of the line'' and is used to identify strings that occur at the end of a line. .DS I 1i :\|\fBg/text.$/s//material./p .R .DE tells the editor to search for all lines ending in ``text.'' (and nothing else, not even a blank space), to change each final ``text.'' to ``material.'', and print the changed lines. .PP The symbol ``^'' indicates the beginning of a line. Thus, .DS I 1i :\|\fBs/^/1. / .R .DE instructs the editor to insert ``1.'' and a space at the beginning of the current line. .PP The characters ``$'' and ``^'' have special meanings only in the context of searching. At other times, they are ordinary characters. If you ever need to search for a character that has a special meaning, you must indicate that the character is to lose temporarily its special significance by typing another special character, the backslash (\\), before it. .DS I 1i :\|\fBs/\\\\\&$/dollar/ .R .DE looks for the character ``$'' in the current line and replaces it by the word ``dollar''. Were it not for the backslash, the ``$'' would have represented ``the end of the line'' in your search rather than the character ``$''. The backslash retains its special significance unless it is preceded by another backslash. .SH Issuing \s-2UNIX\s0 commands from the editor .PP After creating several files with the editor, you may want to delete files no longer useful to you or ask for a list of your files. Removing and listing files are not functions of the editor, and so they require the use of \s-2UNIX\s0 system commands (also referred to as ``shell'' commands, as ``shell'' is the name of the program that processes \s-2UNIX\s0 commands). You do not need to quit the editor to execute a \s-2UNIX\s0 command as long as you indicate that it is to be sent to the shell for execution. To use the \s-2UNIX\s0 command .B rm to remove the file named ``junk'' type: .DS I 1i :\|\fB!rm junk .R ! : .DE The exclamation mark (!) indicates that the rest of the line is to be processed as a shell command. If the buffer contents have not been written since the last change, a warning will be printed before the command is executed: .DS I 1i [No write since last change] .DE The editor prints a ``!'' when the command is completed. Other tutorials describe useful features of the system, of which an editor is only one part. .SH Filenames and file manipulation .PP Throughout each editing session, edit keeps track of the name of the file being edited as the .I "current filename." Edit remembers as the current filename the name given when you entered the editor. The current filename changes whenever the edit (e) command is used to specify a new file. Once edit has recorded a current filename, it inserts that name into any command where a filename has been omitted. If a write command does not specify a file, edit, as we have seen, supplies the current filename. If you are editing a file named ``draft3'' having 283 lines in it, you can have the editor write onto a different file by including its name in the write command: .DS I 1i :\fB\|w chapter3 .R "chapter3" [new file] 283 lines, 8698 characters .DE The current filename remembered by the editor .I will not be changed as a result of the write command. .R Thus, if the next write command does not specify a name, edit will write onto the current file (``draft3'') and not onto the file ``chapter3''. .SH The file (f) command .PP To ask for the current filename, type .B file (or .B f ). In response, the editor provides current information about the buffer, including the filename, your current position, the number of lines in the buffer, and the percent of the distance through the file your current location is. .DS I 1i :\|\fBf .R "text" [Modified] line 3 of 4 --75%-- .DE .\"The expression ``[Edited]'' indicates that the buffer contains .\"either the editor's copy of the existing file ``text'' .\"or a file which you are just now creating. If the contents of the buffer have changed since the last time the file was written, the editor will tell you that the file has been ``[Modified]''. After you save the changes by writing onto a disk file, the buffer will no longer be considered modified: .DS I 1i :\|\fBw .R "text" 4 lines, 88 characters :\|\fBf .R "text" line 3 of 4 --75%-- .DE .SH Reading additional files (r) .PP The \f3read (r)\f1 command allows you to add the contents of a file to the buffer at a specified location, essentially copying new lines between two existing lines. To use it, specify the line after which the new text will be placed, the \f3read (r)\f1 command, and then the name of the file. If you have a file named ``example'', the command .DS I 1i :\|\fB$r example .R "example" 18 lines, 473 characters .DE reads the file ``example'' and adds it to the buffer after the last line. The current filename is not changed by the read command. .SH Writing parts of the buffer .PP The .B write (w) .R command can write all or part of the buffer to a file you specify. We are already familiar with writing the entire contents of the buffer to a disk file. To write only part of the buffer onto a file, indicate the beginning and ending lines before the write command, for example .DS I 1i :\|\fB45,$w ending .R .DE Here all lines from 45 through the end of the buffer are written onto the file named .I ending. The lines remain in the buffer as part of the document you are editing, and you may continue to edit the entire buffer. Your original file is unaffected by your command to write part of the buffer to another file. Edit still remembers whether you have saved changes to the buffer in your original file or not. .SH Recovering files .PP Although it does not happen very often, there are times \s-2UNIX\s+2 stops working because of some malfunction. This situation is known as a \fIcrash\fR. Under most circumstances, edit's crash recovery feature is able to save work to within a few lines of changes before a crash (or an accidental phone hang up). If you lose the contents of an editing buffer in a system crash, you will normally receive mail when you login that gives the name of the recovered file. To recover the file, enter the editor and type the command .B recover (\fBrec\fR), followed by the name of the lost file. For example, to recover the buffer for an edit session involving the file ``chap6'', the command is: .DS I 1i .R :\|\fBrecover chap6 .R .DE Recover is sometimes unable to save the entire buffer successfully, so always check the contents of the saved buffer carefully before writing it back onto the original file. For best results, write the buffer to a new file temporarily so you can examine it without risk to the original file. Unfortunately, you cannot use the recover command to retrieve a file you removed using the shell command \f3rm\f1. .SH Other recovery techniques .PP If something goes wrong when you are using the editor, it may be possible to save your work by using the command .B preserve (\fBpre\fR), which saves the buffer as if the system had crashed. If you are writing a file and you get the message ``Quota exceeded'', you have tried to use more disk storage than is allotted to your account. .I Proceed with caution .R because it is likely that only a part of the editor's buffer is now present in the file you tried to write. In this case you should use the shell escape from the editor (!) to remove some files you don't need and try to write the file again. If this is not possible and you cannot find someone to help you, enter the command .DS I 1i :\|\fBpreserve .R .DE and wait for the reply, .DS I 1i File preserved. .DE If you do not receive this reply, seek help immediately. Do not simply leave the editor. If you do, the buffer will be lost, and you may not be able to save your file. If the reply is ``File preserved.'' you can leave the editor (or logout) to remedy the situation. After a preserve, you can use the recover command once the problem has been corrected, or the \fB\-r\fR option of the edit command if you leave the editor and want to return. .PP If you make an undesirable change to the buffer and type a write command before discovering your mistake, the modified version will replace any previous version of the file. Should you ever lose a good version of a document in this way, do not panic and leave the editor. As long as you stay in the editor, the contents of the buffer remain accessible. Depending on the nature of the problem, it may be possible to restore the buffer to a more complete state with the undo command. After fixing the damaged buffer, you can again write the file to disk. .SH Further reading and other information .PP Edit is an editor designed for beginning and casual users. It is actually a version of a more powerful editor called .I ex. These lessons are intended to introduce you to the editor and its more commonly-used commands. We have not covered all of the editor's commands, but a selection of commands that should be sufficient to accomplish most of your editing tasks. You can find out more about the editor in the .I Ex Reference Manual, .R which is applicable to both .I ex and .I edit. One way to become familiar with the manual is to begin by reading the description of commands that you already know. .bd I 3 .SH Using .I ex .fl .bd I .PP As you become more experienced with using the editor, you may still find that edit continues to meet your needs. However, should you become interested in using .I ex, it is easy to switch. To begin an editing session with .I ex, use the name .B ex in your command instead of .B edit. .PP Edit commands also work in .I ex, but the editing environment is somewhat different. You should be aware of a few differences between .I ex and .I edit. In edit, only the characters ``^'', ``$'', and ``\\'' have special meanings in searching the buffer or indicating characters to be changed by a substitute command. Several additional characters have special meanings in ex, as described in the .I Ex Reference Manual. .R Another feature of the edit environment prevents users from accidently entering two alternative modes of editing, .I open and .I visual, in which the editor behaves quite differently from normal command mode. If you are using ex and you encounter strange behavior, you may have accidently entered open mode by typing ``o''. Type the \s-2ESC\s0 key and then a ``Q'' to get out of open or visual mode and back into the regular editor command mode.

This reference manual describes the command oriented part of .I ex; the display editing features of .I ex are described in .I "An Introduction to Display Editing with Vi." Other documents about the editor include the introduction .I "Edit: A tutorial", the .I "Ex/edit Command Summary", and a .I "Vi Quick Reference" card. .AE .NH 1 Starting ex .PP .FS The financial support of an \s-2IBM\s0 Graduate Fellowship and the National Science Foundation under grants MCS74-07644-A03 and MCS78-07291 is gratefully acknowledged. .FE Each instance of the editor has a set of options, which can be set to tailor it to your liking. The command .I edit invokes a version of .I ex designed for more casual or beginning users by changing the default settings of some of these options. To simplify the description which follows we assume the default settings of the options. .PP When invoked, .I ex determines the terminal type from the \s-2TERM\s0 variable in the environment. It there is a \s-2TERMCAP\s0 variable in the environment, and the type of the terminal described there matches the \s-2TERM\s0 variable, then that description is used. Also if the \s-2TERMCAP\s0 variable contains a pathname (beginning with a \fB/\fR) then the editor will seek the description of the terminal in that file (rather than the default /etc/termcap). If there is a variable \s-2EXINIT\s0 in the environment, then the editor will execute the commands in that variable, otherwise if there is a file .I \&.exrc in your \s-2HOME\s0 directory .I ex reads commands from that file, simulating a .I source command. Option setting commands placed in \s-2EXINIT\s0 or .I \&.exrc will be executed before each editor session. .PP A command to enter .I ex has the following prototype:\(dg .FS \(dg Brackets `[' `]' surround optional parameters here. .FE .DS \fBex\fP [ \fB\-\fP ] [ \fB\-v\fP ] [ \fB\-t\fP \fItag\fP ] [ \fB\-r\fP ] [ \fB\-l\fP ] [ \fB\-w\fP\fIn\fP ] [ \fB\-x\fP ] [ \fB\-R\fP ] [ \fB+\fP\fIcommand\fP ] name ... .DE The most common case edits a single file with no options, i.e.: .DS \fBex\fR name .DE The .B \- command line option option suppresses all interactive-user feedback and is useful in processing editor scripts in command files. The .B \-v option is equivalent to using .I vi rather than .I ex. The .B \-t option is equivalent to an initial .I tag command, editing the file containing the .I tag and positioning the editor at its definition. The .B \-r option is used in recovering after an editor or system crash, retrieving the last saved version of the named file or, if no file is specified, typing a list of saved files. The .B \-l option sets up for editing \s-2LISP\s0, setting the .I showmatch and .I lisp options. The .B \-w option sets the default window size to .I n, and is useful on dialups to start in small windows. The .B \-x option causes .I ex to prompt for a .I key , which is used to encrypt and decrypt the contents of the file, which should already be encrypted using the same key, see .I crypt (1). The .B \-R option sets the .I readonly option at the start. .I Name arguments indicate files to be edited. An argument of the form \fB+\fIcommand\fR indicates that the editor should begin by executing the specified command. If .I command is omitted, then it defaults to ``$'', positioning the editor at the last line of the first file initially. Other useful commands here are scanning patterns of the form ``/pat'' or line numbers, e.g. ``+100'' starting at line 100. .NH 1 File manipulation .NH 2 Current file .PP .I Ex is normally editing the contents of a single file, whose name is recorded in the .I current file name. .I Ex performs all editing actions in a buffer (actually a temporary file) into which the text of the file is initially read. Changes made to the buffer have no effect on the file being edited unless and until the buffer contents are written out to the file with a .I write command. After the buffer contents are written, the previous contents of the written file are no longer accessible. When a file is edited, its name becomes the current file name, and its contents are read into the buffer. .PP The current file is almost always considered to be .I edited. This means that the contents of the buffer are logically connected with the current file name, so that writing the current buffer contents onto that file, even if it exists, is a reasonable action. If the current file is not .I edited then .I ex will not normally write on it if it already exists.* .FS * The .I file command will say ``[Not edited]'' if the current file is not considered edited. .FE .NH 2 Alternate file .PP Each time a new value is given to the current file name, the previous current file name is saved as the .I alternate file name. Similarly if a file is mentioned but does not become the current file, it is saved as the alternate file name. .NH 2 Filename expansion .PP Filenames within the editor may be specified using the normal shell expansion conventions. In addition, the character `%' in filenames is replaced by the .I current file name and the character `#' by the .I alternate file name.\(dg .FS \(dg This makes it easy to deal alternately with two files and eliminates the need for retyping the name supplied on an .I edit command after a .I "No write since last change" diagnostic is received. .FE .NH 2 Multiple files and named buffers .PP If more than one file is given on the command line, then the first file is edited as described above. The remaining arguments are placed with the first file in the .I "argument list." The current argument list may be displayed with the .I args command. The next file in the argument list may be edited with the .I next command. The argument list may also be respecified by specifying a list of names to the .I next command. These names are expanded, the resulting list of names becomes the new argument list, and .I ex edits the first file on the list. .PP For saving blocks of text while editing, and especially when editing more than one file, .I ex has a group of named buffers. These are similar to the normal buffer, except that only a limited number of operations are available on them. The buffers have names .I a through .I z.\(dd .FS \(dd It is also possible to refer to .I A through .I Z; the upper case buffers are the same as the lower but commands append to named buffers rather than replacing if upper case names are used. .FE .NH 2 Read only .PP It is possible to use .I ex in .I "read only" mode to look at files that you have no intention of modifying. This mode protects you from accidently overwriting the file. Read only mode is on when the .I readonly option is set. It can be turned on with the .B \-R command line option, by the .I view command line invocation, or by setting the .I readonly option. It can be cleared by setting .I noreadonly . It is possible to write, even while in read only mode, by indicating that you really know what you are doing. You can write to a different file, or can use the ! form of write, even while in read only mode. .NH 1 Exceptional Conditions .NH 2 Errors and interrupts .PP When errors occur .I ex (optionally) rings the terminal bell and, in any case, prints an error diagnostic. If the primary input is from a file, editor processing will terminate. If an interrupt signal is received, .I ex prints ``Interrupt'' and returns to its command level. If the primary input is a file, then .I ex will exit when this occurs. .NH 2 Recovering from hangups and crashes .PP If a hangup signal is received and the buffer has been modified since it was last written out, or if the system crashes, either the editor (in the first case) or the system (after it reboots in the second) will attempt to preserve the buffer. The next time you log in you should be able to recover the work you were doing, losing at most a few lines of changes from the last point before the hangup or editor crash. To recover a file you can use the .B \-r option. If you were editing the file .I resume, then you should change to the directory where you were when the crash occurred, giving the command .DS \fBex \-r\fP\fI resume\fP .DE After checking that the retrieved file is indeed ok, you can .I write it over the previous contents of that file. .PP You will normally get mail from the system telling you when a file has been saved after a crash. The command .DS \fBex\fP \-\fBr\fP .DE will print a list of the files which have been saved for you. (In the case of a hangup, the file will not appear in the list, although it can be recovered.) .NH 1 Editing modes .PP .I Ex has five distinct modes. The primary mode is .I command mode. Commands are entered in command mode when a `:' prompt is present, and are executed each time a complete line is sent. In .I "text input" mode .I ex gathers input lines and places them in the file. The .I append, .I insert, and .I change commands use text input mode. No prompt is printed when you are in text input mode. This mode is left by typing a `.' alone at the beginning of a line, and .I command mode resumes. .PP The last three modes are .I open and .I visual modes, entered by the commands of the same name, and, within open and visual modes .I "text insertion" mode. .I Open and .I visual modes allow local editing operations to be performed on the text in the file. The .I open command displays one line at a time on any terminal while .I visual works on \s-2CRT\s0 terminals with random positioning cursors, using the screen as a (single) window for file editing changes. These modes are described (only) in .I "An Introduction to Display Editing with Vi." .NH Command structure .PP Most command names are English words, and initial prefixes of the words are acceptable abbreviations. The ambiguity of abbreviations is resolved in favor of the more commonly used commands.* .FS * As an example, the command .I substitute can be abbreviated `s' while the shortest available abbreviation for the .I set command is `se'. .FE .NH 2 Command parameters .PP Most commands accept prefix addresses specifying the lines in the file upon which they are to have effect. The forms of these addresses will be discussed below. A number of commands also may take a trailing .I count specifying the number of lines to be involved in the command.\(dg .FS \(dg Counts are rounded down if necessary. .FE Thus the command ``10p'' will print the tenth line in the buffer while ``delete 5'' will delete five lines from the buffer, starting with the current line. .PP Some commands take other information or parameters, this information always being given after the command name.\(dd .FS \(dd Examples would be option names in a .I set command i.e. ``set number'', a file name in an .I edit command, a regular expression in a .I substitute command, or a target address for a .I copy command, i.e. ``1,5 copy 25''. .FE .NH 2 Command variants .PP A number of commands have two distinct variants. The variant form of the command is invoked by placing an `!' immediately after the command name. Some of the default variants may be controlled by options; in this case, the `!' serves to toggle the default. .NH 2 Flags after commands .PP The characters `#', `p' and `l' may be placed after many commands.** .FS ** A `p' or `l' must be preceded by a blank or tab except in the single special case `dp'. .FE In this case, the command abbreviated by these characters is executed after the command completes. Since .I ex normally prints the new current line after each change, `p' is rarely necessary. Any number of `+' or `\-' characters may also be given with these flags. If they appear, the specified offset is applied to the current line value before the printing command is executed. .NH 2 Comments .PP It is possible to give editor commands which are ignored. This is useful when making complex editor scripts for which comments are desired. The comment character is the double quote: ". Any command line beginning with " is ignored. Comments beginning with " may also be placed at the ends of commands, except in cases where they could be confused as part of text (shell escapes and the substitute and map commands). .NH 2 Multiple commands per line .PP More than one command may be placed on a line by separating each pair of commands by a `|' character. However the .I global commands, comments, and the shell escape `!' must be the last command on a line, as they are not terminated by a `|'. .NH 2 Reporting large changes .PP Most commands which change the contents of the editor buffer give feedback if the scope of the change exceeds a threshold given by the .I report option. This feedback helps to detect undesirably large changes so that they may be quickly and easily reversed with an .I undo. After commands with more global effect such as .I global or .I visual, you will be informed if the net change in the number of lines in the buffer during this command exceeds this threshold. .NH 1 Command addressing .NH 2 Addressing primitives .IP \fB.\fR 20 The current line. Most commands leave the current line as the last line which they affect. The default address for most commands is the current line, thus `\fB.\fR' is rarely used alone as an address. .IP \fIn\fR 20 The \fIn\fRth line in the editor's buffer, lines being numbered sequentially from 1. .IP \fB$\fR 20 The last line in the buffer. .IP \fB%\fR 20 An abbreviation for ``1,$'', the entire buffer. .IP \fI+n\fR\ \fI\-n\fR 20 An offset relative to the current buffer line.\(dg .FS \(dg The forms `.+3' `+3' and `+++' are all equivalent; if the current line is line 100 they all address line 103. .FE .IP \fB/\fIpat\fR\fB/\fR\ \fB?\fIpat\fR\fB?\fR 20 Scan forward and backward respectively for a line containing \fIpat\fR, a regular expression (as defined below). The scans normally wrap around the end of the buffer. If all that is desired is to print the next line containing \fIpat\fR, then the trailing \fB/\fR or \fB?\fR may be omitted. If \fIpat\fP is omitted or explicitly empty, then the last regular expression specified is located.\(dd .FS \(dd The forms \fB\e/\fP and \fB\e?\fP scan using the last regular expression used in a scan; after a substitute \fB//\fP and \fB??\fP would scan using the substitute's regular expression. .FE .IP \fB\(aa\(aa\fP\ \fB\(aa\fP\fIx\fP 20 Before each non-relative motion of the current line `\fB.\fP', the previous current line is marked with a tag, subsequently referred to as `\(aa\(aa'. This makes it easy to refer or return to this previous context. Marks may also be established by the .I mark command, using single lower case letters .I x and the marked lines referred to as `\(aa\fIx\fR'. .NH 2 Combining addressing primitives .PP Addresses to commands consist of a series of addressing primitives, separated by `,' or `;'. Such address lists are evaluated left-to-right. When addresses are separated by `;' the current line `\fB.\fR' is set to the value of the previous addressing expression before the next address is interpreted. If more addresses are given than the command requires, then all but the last one or two are ignored. If the command takes two addresses, the first addressed line must precede the second in the buffer.\(dg .FS \(dg Null address specifications are permitted in a list of addresses, the default in this case is the current line `.'; thus `,100' is equivalent to `\fB.\fR,100'. It is an error to give a prefix address to a command which expects none. .FE .NH 1 Command descriptions .PP The following form is a prototype for all .I ex commands: .DS \fIaddress\fR \fBcommand\fR \fI! parameters count flags\fR .DE All parts are optional; the degenerate case is the empty command which prints the next line in the file. For sanity with use from within .I visual mode, .I ex ignores a ``:'' preceding any command. .PP In the following command descriptions, the default addresses are shown in parentheses, which are .I not, however, part of the command. .LC \fBabbreviate\fR \fIword rhs\fP abbr: \fBab\fP .ZP Add the named abbreviation to the current list. When in input mode in visual, if .I word is typed as a complete word, it will be changed to .I rhs . .LC ( \fB.\fR ) \fBappend\fR abbr: \fBa\fR .br \fItext\fR .br \&\fB.\fR .ZP Reads the input text and places it after the specified line. After the command, `\fB.\fR' addresses the last line input or the specified line if no lines were input. If address `0' is given, text is placed at the beginning of the buffer. .LC \fBa!\fR .br \fItext\fR .br \&\fB.\fR .ZP The variant flag to .I append toggles the setting for the .I autoindent option during the input of .I text. .LC \fBargs\fR .ZP The members of the argument list are printed, with the current argument delimited by `[' and `]'. .ig .PP \fBcd\fR \fIdirectory\fR .ZP The .I cd command is a synonym for .I chdir. .. .LC ( \fB.\fP , \fB.\fP ) \fBchange\fP \fIcount\fP abbr: \fBc\fP .br \fItext\fP .br \&\fB.\fP .ZP Replaces the specified lines with the input \fItext\fP. The current line becomes the last line input; if no lines were input it is left as for a \fIdelete\fP. .LC \fBc!\fP .br \fItext\fP .br \&\fB.\fP .ZP The variant toggles .I autoindent during the .I change. .ig .LC \fBchdir\fR \fIdirectory\fR .ZP The specified \fIdirectory\fR becomes the current directory. If no directory is specified, the current value of the .I home option is used as the target directory. After a .I chdir the current file is not considered to have been edited so that write restrictions on pre-existing files apply. .. .LC ( \fB.\fP , \fB.\fP )\|\fBcopy\fP \fIaddr\fP \fIflags\fP abbr: \fBco\fP .ZP A .I copy of the specified lines is placed after .I addr, which may be `0'. The current line `\fB.\fR' addresses the last line of the copy. The command .I t is a synonym for .I copy. .LC ( \fB.\fR , \fB.\fR )\|\fBdelete\fR \fIbuffer\fR \fIcount\fR \fIflags\fR abbr: \fBd\fR .ZP Removes the specified lines from the buffer. The line after the last line deleted becomes the current line; if the lines deleted were originally at the end, the new last line becomes the current line. If a named .I buffer is specified by giving a letter, then the specified lines are saved in that buffer, or appended to it if an upper case letter is used. .LC \fBedit\fR \fIfile\fR abbr: \fBe\fR .br \fBex\fR \fIfile\fR .ZP Used to begin an editing session on a new file. The editor first checks to see if the buffer has been modified since the last .I write command was issued. If it has been, a warning is issued and the command is aborted. The command otherwise deletes the entire contents of the editor buffer, makes the named file the current file and prints the new filename. After insuring that this file is sensible\(dg .FS \(dg I.e., that it is not a binary file such as a directory, a block or character special file other than .I /dev/tty, a terminal, or a binary or executable file (as indicated by the first word). .FE the editor reads the file into its buffer. .IP If the read of the file completes without error, the number of lines and characters read is typed. If there were any non-\s-2ASCII\s0 characters in the file they are stripped of their non-\s-2ASCII\s0 high bits, and any null characters in the file are discarded. If none of these errors occurred, the file is considered .I edited. If the last line of the input file is missing the trailing newline character, it will be supplied and a complaint will be issued. This command leaves the current line `\fB.\fR' at the last line read.\(dd .FS \(dd If executed from within .I open or .I visual, the current line is initially the first line of the file. .FE .LC \fBe!\fR \fIfile\fR .ZP The variant form suppresses the complaint about modifications having been made and not written from the editor buffer, thus discarding all changes which have been made before editing the new file. .LC \fBe\fR \fB+\fIn\fR \fIfile\fR .ZP Causes the editor to begin at line .I n rather than at the last line; \fIn\fR may also be an editor command containing no spaces, e.g.: ``+/pat''. .LC \fBfile\fR abbr: \fBf\fR .ZP Prints the current file name, whether it has been `[Modified]' since the last .I write command, whether it is .I "read only" , the current line, the number of lines in the buffer, and the percentage of the way through the buffer of the current line.* .FS * In the rare case that the current file is `[Not edited]' this is noted also; in this case you have to use the form \fBw!\fR to write to the file, since the editor is not sure that a \fBwrite\fR will not destroy a file unrelated to the current contents of the buffer. .FE .LC \fBfile\fR \fIfile\fR .ZP The current file name is changed to .I file which is considered `[Not edited]'. .LC ( 1 , $ ) \fBglobal\fR /\fIpat\|\fR/ \fIcmds\fR abbr: \fBg\fR .ZP First marks each line among those specified which matches the given regular expression. Then the given command list is executed with `\fB.\fR' initially set to each marked line. .IP The command list consists of the remaining commands on the current input line and may continue to multiple lines by ending all but the last such line with a `\e'. If .I cmds (and possibly the trailing \fB/\fR delimiter) is omitted, each line matching .I pat is printed. .I Append, .I insert, and .I change commands and associated input are permitted; the `\fB.\fR' terminating input may be omitted if it would be on the last line of the command list. .I Open and .I visual commands are permitted in the command list and take input from the terminal. .IP The .I global command itself may not appear in .I cmds. The .I undo command is also not permitted there, as .I undo instead can be used to reverse the entire .I global command. The options .I autoprint and .I autoindent are inhibited during a .I global, (and possibly the trailing \fB/\fR delimiter) and the value of the .I report option is temporarily infinite, in deference to a \fIreport\fR for the entire global. Finally, the context mark `\'\'' is set to the value of `.' before the global command begins and is not changed during a global command, except perhaps by an .I open or .I visual within the .I global. .LC \fBg!\fR \fB/\fIpat\fB/\fR \fIcmds\fR abbr: \fBv\fR .IP The variant form of \fIglobal\fR runs \fIcmds\fR at each line not matching \fIpat\fR. .LC ( \fB.\fR )\|\fBinsert\fR abbr: \fBi\fR .br \fItext\fR .br \&\fB.\fR .ZP Places the given text before the specified line. The current line is left at the last line input; if there were none input it is left at the line before the addressed line. This command differs from .I append only in the placement of text. .KS .LC \fBi!\fR .br \fItext\fR .br \&\fB.\fR .ZP The variant toggles .I autoindent during the .I insert. .KE .LC ( \fB.\fR , \fB.\fR+1 ) \fBjoin\fR \fIcount\fR \fIflags\fR abbr: \fBj\fR .ZP Places the text from a specified range of lines together on one line. White space is adjusted at each junction to provide at least one blank character, two if there was a `\fB.\fR' at the end of the line, or none if the first following character is a `)'. If there is already white space at the end of the line, then the white space at the start of the next line will be discarded. .LC \fBj!\fR .ZP The variant causes a simpler .I join with no white space processing; the characters in the lines are simply concatenated. .LC ( \fB.\fR ) \fBk\fR \fIx\fR .ZP The .I k command is a synonym for .I mark. It does not require a blank or tab before the following letter. .LC ( \fB.\fR , \fB.\fR ) \fBlist\fR \fIcount\fR \fIflags\fR .ZP Prints the specified lines in a more unambiguous way: tabs are printed as `^I' and the end of each line is marked with a trailing `$'. The current line is left at the last line printed. .LC \fBmap\fR \fIlhs\fR \fIrhs\fR .ZP The .I map command is used to define macros for use in .I visual mode. .I Lhs should be a single character, or the sequence ``#n'', for n a digit, referring to function key \fIn\fR. When this character or function key is typed in .I visual mode, it will be as though the corresponding \fIrhs\fR had been typed. On terminals without function keys, you can type ``#n''. See section 6.9 of the ``Introduction to Display Editing with Vi'' for more details. .LC ( \fB.\fR ) \fBmark\fR \fIx\fR .ZP Gives the specified line mark .I x, a single lower case letter. The .I x must be preceded by a blank or a tab. The addressing form `\'x' then addresses this line. The current line is not affected by this command. .LC ( \fB.\fR , \fB.\fR ) \fBmove\fR \fIaddr\fR abbr: \fBm\fR .ZP The .I move command repositions the specified lines to be after .I addr . The first of the moved lines becomes the current line. .LC \fBnext\fR abbr: \fBn\fR .ZP The next file from the command line argument list is edited. .LC \fBn!\fR .ZP The variant suppresses warnings about the modifications to the buffer not having been written out, discarding (irretrievably) any changes which may have been made. .LC \fBn\fR \fIfilelist\fR .br \fBn\fR \fB+\fIcommand\fR \fIfilelist\fR .ZP The specified .I filelist is expanded and the resulting list replaces the current argument list; the first file in the new list is then edited. If .I command is given (it must contain no spaces), then it is executed after editing the first such file. .LC ( \fB.\fR , \fB.\fR ) \fBnumber\fR \fIcount\fR \fIflags\fR abbr: \fB#\fR or \fBnu\fR .ZP Prints each specified line preceded by its buffer line number. The current line is left at the last line printed. .KS .LC ( \fB.\fR ) \fBopen\fR \fIflags\fR abbr: \fBo\fR .br ( \fB.\fR ) \fBopen\fR /\fIpat\|\fR/ \fIflags\fR .ZP Enters intraline editing \fIopen\fR mode at each addressed line. If .I pat is given, then the cursor will be placed initially at the beginning of the string matched by the pattern. To exit this mode use Q. See .I "An Introduction to Display Editing with Vi" for more details. .KE .LC \fBpreserve\fR .ZP The current editor buffer is saved as though the system had just crashed. This command is for use only in emergencies when a .I write command has resulted in an error and you don't know how to save your work. After a .I preserve you should seek help. .LC ( \fB.\fR , \fB.\fR )\|\fBprint\fR \fIcount\fR abbr: \fBp\fR or \fBP\fR .ZP Prints the specified lines with non-printing characters printed as control characters `^\fIx\fR\|'; delete (octal 177) is represented as `^?'. The current line is left at the last line printed. .LC ( \fB.\fR )\|\fBput\fR \fIbuffer\fR abbr: \fBpu\fR .ZP Puts back previously .I deleted or .I yanked lines. Normally used with .I delete to effect movement of lines, or with .I yank to effect duplication of lines. If no .I buffer is specified, then the last .I deleted or .I yanked text is restored.* .FS * But no modifying commands may intervene between the .I delete or .I yank and the .I put, nor may lines be moved between files without using a named buffer. .FE By using a named buffer, text may be restored that was saved there at any previous time. .LC \fBquit\fR abbr: \fBq\fR .ZP Causes .I ex to terminate. No automatic write of the editor buffer to a file is performed. However, .I ex issues a warning message if the file has changed since the last .I write command was issued, and does not .I quit.\(dg .FS \(dg \fIEx\fR will also issue a diagnostic if there are more files in the argument list. .FE Normally, you will wish to save your changes, and you should give a \fIwrite\fR command; if you wish to discard them, use the \fBq!\fR command variant. .LC \fBq!\fR .ZP Quits from the editor, discarding changes to the buffer without complaint. .LC ( \fB.\fR ) \fBread\fR \fIfile\fR abbr: \fBr\fR .ZP Places a copy of the text of the given file in the editing buffer after the specified line. If no .I file is given the current file name is used. The current file name is not changed unless there is none in which case .I file becomes the current name. The sensibility restrictions for the .I edit command apply here also. If the file buffer is empty and there is no current name then .I ex treats this as an .I edit command. .IP Address `0' is legal for this command and causes the file to be read at the beginning of the buffer. Statistics are given as for the .I edit command when the .I read successfully terminates. After a .I read the current line is the last line read.\(dd .FS \(dd Within .I open and .I visual the current line is set to the first line read rather than the last. .FE .LC ( \fB.\fR ) \fBread\fR \fB!\fR\fIcommand\fR .ZP Reads the output of the command .I command into the buffer after the specified line. This is not a variant form of the command, rather a read specifying a .I command rather than a .I filename; a blank or tab before the \fB!\fR is mandatory. .LC \fBrecover \fIfile\fR .ZP Recovers .I file from the system save area. Used after a accidental hangup of the phone** .FS ** The system saves a copy of the file you were editing only if you have made changes to the file. .FE or a system crash** or .I preserve command. Except when you use .I preserve you will be notified by mail when a file is saved. .LC \fBrewind\fR abbr: \fBrew\fR .ZP The argument list is rewound, and the first file in the list is edited. .LC \fBrew!\fR .ZP Rewinds the argument list discarding any changes made to the current buffer. .LC \fBset\fR \fIparameter\fR .ZP With no arguments, prints those options whose values have been changed from their defaults; with parameter .I all it prints all of the option values. .IP Giving an option name followed by a `?' causes the current value of that option to be printed. The `?' is unnecessary unless the option is Boolean valued. Boolean options are given values either by the form `set \fIoption\fR' to turn them on or `set no\fIoption\fR' to turn them off; string and numeric options are assigned via the form `set \fIoption\fR=value'. .IP More than one parameter may be given to .I set \|; they are interpreted left-to-right. .LC \fBshell\fR abbr: \fBsh\fR .IP A new shell is created. When it terminates, editing resumes. .LC \fBsource\fR \fIfile\fR abbr: \fBso\fR .IP Reads and executes commands from the specified file. .I Source commands may be nested. .LC ( \fB.\fR , \fB.\fR ) \fBsubstitute\fR /\fIpat\fR\|/\fIrepl\fR\|/ \fIoptions\fR \fIcount\fR \fIflags\fR abbr: \fBs\fR .IP On each specified line, the first instance of pattern .I pat is replaced by replacement pattern .I repl. If the .I global indicator option character `g' appears, then all instances are substituted; if the .I confirm indication character `c' appears, then before each substitution the line to be substituted is typed with the string to be substituted marked with `\(ua' characters. By typing an `y' one can cause the substitution to be performed, any other input causes no change to take place. After a .I substitute the current line is the last line substituted. .IP Lines may be split by substituting new-line characters into them. The newline in .I repl must be escaped by preceding it with a `\e'. Other metacharacters available in .I pat and .I repl are described below. .LC .B stop .ZP Suspends the editor, returning control to the top level shell. If .I autowrite is set and there are unsaved changes, a write is done first unless the form .B stop ! is used. This commands is only available where supported by the teletype driver and operating system. .LC ( \fB.\fR , \fB.\fR ) \fBsubstitute\fR \fIoptions\fR \fIcount\fR \fIflags\fR abbr: \fBs\fR .ZP If .I pat and .I repl are omitted, then the last substitution is repeated. This is a synonym for the .B & command. .LC ( \fB.\fR , \fB.\fR ) \fBt\fR \fIaddr\fR \fIflags\fR .ZP The .I t command is a synonym for .I copy . .LC \fBta\fR \fItag\fR .ZP The focus of editing switches to the location of .I tag, switching to a different line in the current file where it is defined, or if necessary to another file.\(dd .FS \(dd If you have modified the current file before giving a .I tag command, you must write it out; giving another .I tag command, specifying no .I tag will reuse the previous tag. .FE .IP The tags file is normally created by a program such as .I ctags, and consists of a number of lines with three fields separated by blanks or tabs. The first field gives the name of the tag, the second the name of the file where the tag resides, and the third gives an addressing form which can be used by the editor to find the tag; this field is usually a contextual scan using `/\fIpat\fR/' to be immune to minor changes in the file. Such scans are always performed as if .I nomagic was set. .PP The tag names in the tags file must be sorted alphabetically. .LC \fBunabbreviate\fR \fIword\fP abbr: \fBuna\fP .ZP Delete .I word from the list of abbreviations. .LC \fBundo\fR abbr: \fBu\fR .ZP Reverses the changes made in the buffer by the last buffer editing command. Note that .I global commands are considered a single command for the purpose of .I undo (as are .I open and .I visual.) Also, the commands .I write and .I edit which interact with the file system cannot be undone. .I Undo is its own inverse. .IP .I Undo always marks the previous value of the current line `\fB.\fR' as `\'\''. After an .I undo the current line is the first line restored or the line before the first line deleted if no lines were restored. For commands with more global effect such as .I global and .I visual the current line regains it's pre-command value after an .I undo. .LC \fBunmap\fR \fIlhs\fR .ZP The macro expansion associated by .I map for .I lhs is removed. .LC ( 1 , $ ) \fBv\fR /\fIpat\fR\|/ \fIcmds\fR .ZP A synonym for the .I global command variant \fBg!\fR, running the specified \fIcmds\fR on each line which does not match \fIpat\fR. .LC \fBversion\fR abbr: \fBve\fR .ZP Prints the current version number of the editor as well as the date the editor was last changed. .LC ( \fB.\fR ) \fBvisual\fR \fItype\fR \fIcount\fR \fIflags\fR abbr: \fBvi\fR .ZP Enters visual mode at the specified line. .I Type is optional and may be `\-' , `\(ua' or `\fB.\fR' as in the .I z command to specify the placement of the specified line on the screen. By default, if .I type is omitted, the specified line is placed as the first on the screen. A .I count specifies an initial window size; the default is the value of the option .I window. See the document .I "An Introduction to Display Editing with Vi" for more details. To exit this mode, type Q. .LC \fBvisual\fP file .br \fBvisual\fP +\fIn\fP file .ZP From visual mode, this command is the same as edit. .LC ( 1 , $ ) \fBwrite\fR \fIfile\fR abbr: \fBw\fR .ZP Writes changes made back to \fIfile\fR, printing the number of lines and characters written. Normally \fIfile\fR is omitted and the text goes back where it came from. If a \fIfile\fR is specified, then text will be written to that file.* .FS * The editor writes to a file only if it is the current file and is .I edited , if the file does not exist, or if the file is actually a teletype, .I /dev/tty, .I /dev/null. Otherwise, you must give the variant form \fBw!\fR to force the write. .FE If the file does not exist it is created. The current file name is changed only if there is no current file name; the current line is never changed. .IP If an error occurs while writing the current and .I edited file, the editor considers that there has been ``No write since last change'' even if the buffer had not previously been modified. .LC ( 1 , $ ) \fBwrite>>\fR \fIfile\fR abbr: \fBw>>\fR .ZP Writes the buffer contents at the end of an existing file. .IP .LC \fBw!\fR \fIname\fR .ZP Overrides the checking of the normal \fIwrite\fR command, and will write to any file which the system permits. .LC ( 1 , $ ) \fBw\fR \fB!\fR\fIcommand\fR .ZP Writes the specified lines into .I command. Note the difference between \fBw!\fR which overrides checks and \fBw\ \ !\fR which writes to a command. .LC \fBwq\fR \fIname\fR .ZP Like a \fIwrite\fR and then a \fIquit\fR command. .LC \fBwq!\fR \fIname\fR .ZP The variant overrides checking on the sensibility of the .I write command, as \fBw!\fR does. .LC \fBxit\fP \fIname\fR .ZP If any changes have been made and not written, writes the buffer out. Then, in any case, quits. .LC ( \fB.\fR , \fB.\fR )\|\fByank\fR \fIbuffer\fR \fIcount\fR abbr: \fBya\fR .ZP Places the specified lines in the named .I buffer, for later retrieval via .I put. If no buffer name is specified, the lines go to a more volatile place; see the \fIput\fR command description. .LC ( \fB.+1\fR ) \fBz\fR \fIcount\fR .ZP Print the next \fIcount\fR lines, default \fIwindow\fR. .LC ( \fB.\fR ) \fBz\fR \fItype\fR \fIcount\fR .ZP Prints a window of text with the specified line at the top. If \fItype\fR is `\-' the line is placed at the bottom; a `\fB.\fR' causes the line to be placed in the center.* A count gives the number of lines to be displayed rather than double the number specified by the \fIscroll\fR option. On a \s-2CRT\s0 the screen is cleared before display begins unless a count which is less than the screen size is given. The current line is left at the last line printed. .FS * Forms `z=' and `z\(ua' also exist; `z=' places the current line in the center, surrounds it with lines of `\-' characters and leaves the current line at this line. The form `z\(ua' prints the window before `z\-' would. The characters `+', `\(ua' and `\-' may be repeated for cumulative effect. On some v2 editors, no .I type may be given. .FE .LC \fB!\fR \fIcommand\fR\fR .ZP The remainder of the line after the `!' character is sent to a shell to be executed. Within the text of .I command the characters `%' and `#' are expanded as in filenames and the character `!' is replaced with the text of the previous command. Thus, in particular, `!!' repeats the last such shell escape. If any such expansion is performed, the expanded line will be echoed. The current line is unchanged by this command. .IP If there has been ``[No\ write]'' of the buffer contents since the last change to the editing buffer, then a diagnostic will be printed before the command is executed as a warning. A single `!' is printed when the command completes. .LC ( \fIaddr\fR , \fIaddr\fR ) \fB!\fR \fIcommand\fR\fR .ZP Takes the specified address range and supplies it as standard input to .I command; the resulting output then replaces the input lines. .LC ( $ ) \fB=\fR .ZP Prints the line number of the addressed line. The current line is unchanged. .KS .LC ( \fB.\fR , \fB.\fR ) \fB>\fR \fIcount\fR \fIflags\fR .br ( \fB.\fR , \fB.\fR ) \fB<\fR \fIcount\fR \fIflags\fR .IP Perform intelligent shifting on the specified lines; \fB<\fR shifts left and \fB>\fR shift right. The quantity of shift is determined by the .I shiftwidth option and the repetition of the specification character. Only white space (blanks and tabs) is shifted; no non-white characters are discarded in a left-shift. The current line becomes the last line which changed due to the shifting. .KE .LC \fB^D\fR .ZP An end-of-file from a terminal input scrolls through the file. The .I scroll option specifies the size of the scroll, normally a half screen of text. .LC ( \fB.\fR+1 , \fB.\fR+1 ) .br ( \fB.\fR+1 , \fB.\fR+1 ) | .ZP An address alone causes the addressed lines to be printed. A blank line prints the next line in the file. .LC ( \fB.\fR , \fB.\fR ) \fB&\fR \fIoptions\fR \fIcount\fR \fIflags\fR .ZP Repeats the previous .I substitute command. .LC ( \fB.\fR , \fB.\fR ) \fB\s+2~\s0\fR \fIoptions\fR \fIcount\fR \fIflags\fR .ZP Replaces the previous regular expression with the previous replacement pattern from a substitution. .NH 1 Regular expressions and substitute replacement patterns .NH 2 Regular expressions .PP A regular expression specifies a set of strings of characters. A member of this set of strings is said to be .I matched by the regular expression. .I Ex remembers two previous regular expressions: the previous regular expression used in a .I substitute command and the previous regular expression used elsewhere (referred to as the previous \fIscanning\fR regular expression.) The previous regular expression can always be referred to by a null \fIre\fR, e.g. `//' or `??'. .NH 2 Magic and nomagic .PP The regular expressions allowed by .I ex are constructed in one of two ways depending on the setting of the .I magic option. The .I ex and .I vi default setting of .I magic gives quick access to a powerful set of regular expression metacharacters. The disadvantage of .I magic is that the user must remember that these metacharacters are .I magic and precede them with the character `\e' to use them as ``ordinary'' characters. With .I nomagic, the default for .I edit, regular expressions are much simpler, there being only two metacharacters. The power of the other metacharacters is still available by preceding the (now) ordinary character with a `\e'. Note that `\e' is thus always a metacharacter. .PP The remainder of the discussion of regular expressions assumes that that the setting of this option is .I magic.\(dg .FS \(dg To discern what is true with .I nomagic it suffices to remember that the only special characters in this case will be `\(ua' at the beginning of a regular expression, `$' at the end of a regular expression, and `\e'. With .I nomagic the characters `\s+2~\s0' and `&' also lose their special meanings related to the replacement pattern of a substitute. .FE .NH 2 Basic regular expression summary .PP The following basic constructs are used to construct .I magic mode regular expressions. .IP \fIchar\fR 15 An ordinary character matches itself. The characters `\(ua' at the beginning of a line, `$' at the end of line, `*' as any character other than the first, `.', `\e', `[', and `\s+2~\s0' are not ordinary characters and must be escaped (preceded) by `\e' to be treated as such. .IP \fB\(ua\fR At the beginning of a pattern forces the match to succeed only at the beginning of a line. .IP \fB$\fR At the end of a regular expression forces the match to succeed only at the end of the line. .IP \&\fB.\fR Matches any single character except the new-line character. .IP \fB\e<\fR Forces the match to occur only at the beginning of a ``variable'' or ``word''; that is, either at the beginning of a line, or just before a letter, digit, or underline and after a character not one of these. .IP \fB\e>\fR Similar to `\e<', but matching the end of a ``variable'' or ``word'', i.e. either the end of the line or before character which is neither a letter, nor a digit, nor the underline character. .IP \fB[\fIstring\fR]\fR Matches any (single) character in the class defined by .I string. Most characters in .I string define themselves. A pair of characters separated by `\-' in .I string defines the set of characters collating between the specified lower and upper bounds, thus `[a\-z]' as a regular expression matches any (single) lower-case letter. If the first character of .I string is an `\(ua' then the construct matches those characters which it otherwise would not; thus `[\(uaa\-z]' matches anything but a lower-case letter (and of course a newline). To place any of the characters `\(ua', `[', or `\-' in .I string you must escape them with a preceding `\e'. .NH 2 Combining regular expression primitives .PP The concatenation of two regular expressions matches the leftmost and then longest string which can be divided with the first piece matching the first regular expression and the second piece matching the second. Any of the (single character matching) regular expressions mentioned above may be followed by the character `*' to form a regular expression which matches any number of adjacent occurrences (including 0) of characters matched by the regular expression it follows. .PP The character `\s+2~\s0' may be used in a regular expression, and matches the text which defined the replacement part of the last .I substitute command. A regular expression may be enclosed between the sequences `\e(' and `\e)' with side effects in the .I substitute replacement patterns. .NH 2 Substitute replacement patterns .PP The basic metacharacters for the replacement pattern are `&' and `~'; these are given as `\e&' and `\e~' when .I nomagic is set. Each instance of `&' is replaced by the characters which the regular expression matched. The metacharacter `~' stands, in the replacement pattern, for the defining text of the previous replacement pattern. .PP Other metasequences possible in the replacement pattern are always introduced by the escaping character `\e'. The sequence `\e\fIn\fR' is replaced by the text matched by the \fIn\fR-th regular subexpression enclosed between `\e(' and `\e)'.\(dg .FS \(dg When nested, parenthesized subexpressions are present, \fIn\fR is determined by counting occurrences of `\e(' starting from the left. .FE The sequences `\eu' and `\el' cause the immediately following character in the replacement to be converted to upper- or lower-case respectively if this character is a letter. The sequences `\eU' and `\eL' turn such conversion on, either until `\eE' or `\ee' is encountered, or until the end of the replacement pattern. .de LC .br .sp .1i .ne 4 .LP .ta 3i .. .NH 1 Option descriptions .PP .LC \fBautoindent\fR, \fBai\fR default: noai .ZP Can be used to ease the preparation of structured program text. At the beginning of each .I append , .I change or .I insert command or when a new line is .I opened or created by an .I append , .I change , .I insert , or .I substitute operation within .I open or .I visual mode, .I ex looks at the line being appended after, the first line changed or the line inserted before and calculates the amount of white space at the start of the line. It then aligns the cursor at the level of indentation so determined. .IP If the user then types lines of text in, they will continue to be justified at the displayed indenting level. If more white space is typed at the beginning of a line, the following line will start aligned with the first non-white character of the previous line. To back the cursor up to the preceding tab stop one can hit \fB^D\fR. The tab stops going backwards are defined at multiples of the .I shiftwidth option. You .I cannot backspace over the indent, except by sending an end-of-file with a \fB^D\fR. .IP Specially processed in this mode is a line with no characters added to it, which turns into a completely blank line (the white space provided for the .I autoindent is discarded.) Also specially processed in this mode are lines beginning with an `\(ua' and immediately followed by a \fB^D\fR. This causes the input to be repositioned at the beginning of the line, but retaining the previous indent for the next line. Similarly, a `0' followed by a \fB^D\fR repositions at the beginning but without retaining the previous indent. .IP .I Autoindent doesn't happen in .I global commands or when the input is not a terminal. .LC \fBautoprint\fR, \fBap\fR default: ap .ZP Causes the current line to be printed after each .I delete , .I copy , .I join , .I move , .I substitute , .I t , .I undo or shift command. This has the same effect as supplying a trailing `p' to each such command. .I Autoprint is suppressed in globals, and only applies to the last of many commands on a line. .LC \fBautowrite\fR, \fBaw\fR default: noaw .ZP Causes the contents of the buffer to be written to the current file if you have modified it and give a .I next, .I rewind, .I stop, .I tag, or .I ! command, or a \fB^\(ua\fR (switch files) or \fB^]\fR (tag goto) command in .I visual. Note, that the .I edit and .I ex commands do .B not autowrite. In each case, there is an equivalent way of switching when autowrite is set to avoid the .I autowrite (\fIedit\fR for .I next , .I rewind! for .I rewind , .I stop! for .I stop , .I tag! for .I tag , .I shell for .I ! , and \fB:e\ #\fR and a \fB:ta!\fR command from within .I visual). .LC \fBbeautify\fR, \fBbf\fR default: nobeautify .ZP Causes all control characters except tab, newline and form-feed to be discarded from the input. A complaint is registered the first time a backspace character is discarded. .I Beautify does not apply to command input. .LC \fBdirectory\fR, \fBdir\fR default: dir=/tmp .ZP Specifies the directory in which .I ex places its buffer file. If this directory in not writable, then the editor will exit abruptly when it fails to be able to create its buffer there. .LC \fBedcompatible\fR default: noedcompatible .ZP Causes the presence of absence of .B g and .B c suffixes on substitute commands to be remembered, and to be toggled by repeating the suffices. The suffix .B r makes the substitution be as in the .I ~ command, instead of like .I &. .LC \fBerrorbells\fR, \fBeb\fR default: noeb .ZP Error messages are preceded by a bell.* .FS * Bell ringing in .I open and .I visual on errors is not suppressed by setting .I noeb. .FE If possible the editor always places the error message in a standout mode of the terminal (such as inverse video) instead of ringing the bell. .LC \fBhardtabs\fR, \fBht\fR default: ht=8 .ZP Gives the boundaries on which terminal hardware tabs are set (or on which the system expands tabs). .LC \fBignorecase\fR, \fBic\fR default: noic .ZP All upper case characters in the text are mapped to lower case in regular expression matching. In addition, all upper case characters in regular expressions are mapped to lower case except in character class specifications. .LC \fBlisp\fR default: nolisp .ZP \fIAutoindent\fR indents appropriately for .I lisp code, and the \fB( ) { } [[\fR and \fB]]\fR commands in .I open and .I visual are modified to have meaning for \fIlisp\fR. .LC \fBlist\fR default: nolist .ZP All printed lines will be displayed (more) unambiguously, showing tabs and end-of-lines as in the .I list command. .LC \fBmagic\fR default: magic for \fIex\fR and \fIvi\fR\(dg .FS \(dg \fINomagic\fR for \fIedit\fR. .FE .ZP If .I nomagic is set, the number of regular expression metacharacters is greatly reduced, with only `\(ua' and `$' having special effects. In addition the metacharacters `~' and `&' of the replacement pattern are treated as normal characters. All the normal metacharacters may be made .I magic when .I nomagic is set by preceding them with a `\e'. .LC \fBmesg\fR default: mesg .ZP Causes write permission to be turned off to the terminal while you are in visual mode, if .I nomesg is set. .LC \fBmodeline\fR default: nomodeline .ZP If .I modeline is set, then the first 5 lines and the last five lines of the file will be checked for ex command lines and the comands issued. To be recognized as a command line, the line must have the string .B ex: or .B vi: preceeded by a tab or a space. This string may be anywhere in the line and anything after the .I : is interpeted as editor commands. This option defaults to off because of unexpected behavior when editting files such as .I /etc/passwd. .LC \fBnumber, nu\fR default: nonumber .ZP Causes all output lines to be printed with their line numbers. In addition each input line will be prompted for by supplying the line number it will have. .LC \fBopen\fR default: open .ZP If \fInoopen\fR, the commands .I open and .I visual are not permitted. This is set for .I edit to prevent confusion resulting from accidental entry to open or visual mode. .LC \fBoptimize, opt\fR default: optimize .ZP Throughput of text is expedited by setting the terminal to not do automatic carriage returns when printing more than one (logical) line of output, greatly speeding output on terminals without addressable cursors when text with leading white space is printed. .LC \fBparagraphs,\ para\fR default: para=IPLPPPQPP\0LIbp .ZP Specifies the paragraphs for the \fB{\fR and \fB}\fR operations in .I open and .I visual. The pairs of characters in the option's value are the names of the macros which start paragraphs. .LC \fBprompt\fR default: prompt .ZP Command mode input is prompted for with a `:'. .LC \fBredraw\fR default: noredraw .ZP The editor simulates (using great amounts of output), an intelligent terminal on a dumb terminal (e.g. during insertions in .I visual the characters to the right of the cursor position are refreshed as each input character is typed.) Useful only at very high speed. .LC \fBremap\fP default: remap .ZP If on, macros are repeatedly tried until they are unchanged. For example, if .B o is mapped to .B O , and .B O is mapped to .B I , then if .I remap is set, .B o will map to .B I , but if .I noremap is set, it will map to .B O . .LC \fBreport\fR default: report=5\(dg .FS \(dg 2 for \fIedit\fR. .FE .ZP Specifies a threshold for feedback from commands. Any command which modifies more than the specified number of lines will provide feedback as to the scope of its changes. For commands such as .I global , .I open , .I undo , and .I visual which have potentially more far reaching scope, the net change in the number of lines in the buffer is presented at the end of the command, subject to this same threshold. Thus notification is suppressed during a .I global command on the individual commands performed. .LC \fBscroll\fR default: scroll=\(12 window .ZP Determines the number of logical lines scrolled when an end-of-file is received from a terminal input in command mode, and the number of lines printed by a command mode .I z command (double the value of .I scroll ). .LC \fBsections\fR default: sections=SHNHH\0HU .ZP Specifies the section macros for the \fB[[\fR and \fB]]\fR operations in .I open and .I visual. The pairs of characters in the options's value are the names of the macros which start paragraphs. .LC \fBshell\fR, \fBsh\fR default: sh=/bin/sh .ZP Gives the path name of the shell forked for the shell escape command `!', and by the .I shell command. The default is taken from SHELL in the environment, if present. .LC \fBshiftwidth\fR, \fBsw\fR default: sw=8 .ZP Gives the width a software tab stop, used in reverse tabbing with \fB^D\fR when using .I autoindent to append text, and by the shift commands. .LC \fBshowmatch, sm\fR default: nosm .ZP In .I open and .I visual mode, when a \fB)\fR or \fB}\fR is typed, move the cursor to the matching \fB(\fR or \fB{\fR for one second if this matching character is on the screen. Extremely useful with .I lisp. .LC \fBslowopen, slow\fR terminal dependent .ZP Affects the display algorithm used in .I visual mode, holding off display updating during input of new text to improve throughput when the terminal in use is both slow and unintelligent. See .I "An Introduction to Display Editing with Vi" for more details. .LC \fBtabstop,\ ts\fR default: ts=8 .ZP The editor expands tabs in the input file to be on .I tabstop boundaries for the purposes of display. .LC \fBtaglength,\ tl\fR default: tl=0 .ZP Tags are not significant beyond this many characters. A value of zero (the default) means that all characters are significant. .LC \fBtags\fR default: tags=tags /usr/lib/tags .ZP A path of files to be used as tag files for the .I tag command. A requested tag is searched for in the specified files, sequentially. By default, files called .B tags are searched for in the current directory and in /usr/lib (a master file for the entire system). .LC \fBterm\fR from environment TERM .ZP The terminal type of the output device. .LC \fBterse\fR default: noterse .ZP Shorter error diagnostics are produced for the experienced user. .LC \fBwarn\fR default: warn .ZP Warn if there has been `[No write since last change]' before a `!' command escape. .LC \fBwindow\fR default: window=speed dependent .ZP The number of lines in a text window in the .I visual command. The default is 8 at slow speeds (600 baud or less), 16 at medium speed (1200 baud), and the full screen (minus one line) at higher speeds. .LC \fBw300,\ w1200\, w9600\fR .ZP These are not true options but set .B window only if the speed is slow (300), medium (1200), or high (9600), respectively. They are suitable for an EXINIT and make it easy to change the 8/16/full screen rule. .LC \fBwrapscan\fR, \fBws\fR default: ws .ZP Searches using the regular expressions in addressing will wrap around past the end of the file. .LC \fBwrapmargin\fR, \fBwm\fR default: wm=0 .ZP Defines a margin for automatic wrapover of text during input in .I open and .I visual modes. See .I "An Introduction to Text Editing with Vi" for details. .LC \fBwriteany\fR, \fBwa\fR default: nowa .IP Inhibit the checks normally made before .I write commands, allowing a write to any file which the system protection mechanism will allow. .NH 1 Acknowledgements .PP Chuck Haley contributed greatly to the early development of .I ex.

In terms of command syntax and effect the editors are essentially identical, and this command summary applies to both. .PP The summary is meant as a quick reference for users already acquainted with .I edit or \fIex\fP. Fuller explanations of the editors are available in the documents .I Edit: A Tutorial .R (a self-teaching introduction) and the .I Ex Reference Manual .R (the comprehensive reference source for both \fIedit\fP and \fIex\fP). Both of these writeups are available in the Computing Services Library. .PP In the examples included with the summary, commands and text entered by the user are printed in \fBboldface\fR to distinguish them from responses printed by the computer. .sp 0.45v .LP .B The Editor Buffer .PP In order to perform its tasks the editor sets aside a temporary work space, called a \fIbuffer\fR, separate from the user's permanent file. Before starting to work on an existing file the editor makes a copy of it in the buffer, leaving the original untouched. All editing changes are made to the buffer copy, which must then be written back to the permanent file in order to update the old version. The buffer disappears at the end of the editing session. .sp 0.45v .LP .B Editing: Command and Text Input Modes .PP .R During an editing session there are two usual modes of operation: \fIcommand\fP mode and \fItext input\fP mode. (This disregards, for the moment, .I open and .I visual modes, discussed below.) In command mode, the editor issues a colon prompt (:) to show that it is ready to accept and execute a command. In text input mode, on the other hand, there is no prompt and the editor merely accepts text to be added to the buffer. Text input mode is initiated by the commands \fIappend\fP, \fIinsert\fP, and \fIchange\fP, and is terminated by typing a period as the first and only character on a line. .sp 0.45v .LP .B Line Numbers and Command Syntax .PP .R The editor keeps track of lines of text in the buffer by numbering them consecutively starting with 1 and renumbering as lines are added or deleted. At any given time the editor is positioned at one of these lines; this position is called the \fIcurrent line\fP. Generally, commands that change the contents of the buffer print the new current line at the end of their execution. .PP Most commands can be preceded by one or two line-number addresses which indicate the lines to be affected. If one number is given the command operates on that line only; if two, on an inclusive range of lines. Commands that can take line-number prefixes also assume default prefixes if none are given. The default assumed by each command is designed to make it convenient to use in many instances without any line-number prefix. For the most part, a command used without a prefix operates on the current line, though exceptions to this rule should be noted. The \fIprint\fP command by itself, for instance, causes one line, the current line, to be printed at the terminal. .PP The summary shows the number of line addresses that can be prefixed to each command as well as the defaults assumed if they are omitted. For example, .I (.,.) means that up to 2 line-numbers may be given, and that if none is given the command operates on the current line. (In the address prefix notation, ``.'' stands for the current line and ``$'' stands for the last line of the buffer.) If no such notation appears, no line-number prefix may be used. .PP Some commands take trailing information; only the more important instances of this are mentioned in the summary. .sp 0.25v .LP .B Open and Visual Modes .PP .R Besides command and text input modes, .I ex and .I edit provide on some CRT terminals other modes of editing, .I open and .I visual . In these modes the cursor can be moved to individual words or characters in a line. The commands then given are very different from the standard editor commands; most do not appear on the screen when typed. .I An Introduction to Display Editing with Vi .R provides a full discussion. .sp 0.25v .LP .B Special Characters .PP .R .fi Some characters take on special meanings when used in context searches and in patterns given to the \fIsubstitute\fP command. For \fIedit\fR, these are ``^'' and ``$'', meaning the beginning and end of a line, respectively. .I Ex has the following additional special characters: .B .ce 1 \&. & * [ ] ~ .R To use one of the special characters as its simple graphic representation rather than with its special meaning, precede it by a backslash (\\). The backslash always has a special meaning. .1C .TS cp10 cp10 cp10 cp10 ltw(1.0i) lt2w(0.40i)fB ltw(3.0i) ltw(1.8i).

For the rest of this manual page, .I nex/nvi is used only when it's necessary to distinguish it from the historic implementations of .IR ex/vi . .PP This manual page is intended for users already familiar with .IR ex/vi . Anyone else should almost certainly read a good tutorial on the editor before this manual page. If you're in an unfamiliar environment, and you absolutely have to get work done immediately, read the section after the options description, entitled ``Fast Startup''. It's probably enough to get you going. .PP The following options are available: .TP .B \-c Execute .B cmd immediately after starting the edit session. Particularly useful for initial positioning in the file, however .B cmd is not limited to positioning commands. This is the POSIX 1003.2 interface for the historic ``+cmd'' syntax. .I Nex/nvi supports both the old and new syntax. .TP .B \-e Start editing in ex mode, as if the command name were .IR \&ex . .TP .B \-F Don't copy the entire file when first starting to edit. (The default is to make a copy in case someone else modifies the file during your edit session.) .TP .B \-l Start editing with the lisp and showmatch options set. .TP .B \-R Start editing in read-only mode, as if the command name was .IR view , or the .B readonly option was set. .TP .B \-r Recover the specified files, or, if no files are specified, list the files that could be recovered. If no recoverable files by the specified name exist, the file is edited as if the .B \-r option had not been specified. .TP .B \-S Run with the .B secure edit option set, disallowing all access to external programs. .TP .B \-s Enter batch mode; applicable only to .I \&ex edit sessions. Batch mode is useful when running .I \&ex scripts. Prompts, informative messages and other user oriented message are turned off, and no startup files or environmental variables are read. This is the POSIX 1003.2 interface for the historic ``\-'' argument. .I \&Nex/nvi supports both the old and new syntax. .TP .B \-t Start editing at the specified tag. (See .IR ctags (1)). .TP .B \-w Set the initial window size to the specified number of lines. .TP .B \-v Start editing in vi mode, as if the command name was .I \&vi or .IR view . .PP Command input for .I ex/vi is read from the standard input. In the .I \&vi interface, it is an error if standard input is not a terminal. In the .I \&ex interface, if standard input is not a terminal, .I \&ex will read commands from it regardless, however, the session will be a batch mode session, exactly as if the .B \-s option had been specified. .PP .I Ex/vi exits 0 on success, and greater than 0 if an error occurs. .SH FAST STARTUP This section will tell you the minimum amount that you need to do simple editing tasks using .IR \&vi . If you've never used any screen editor before, you're likely to have problems even with this simple introduction. In that case you should find someone that already knows .I \&vi and have them walk you through this section. .PP .I \&Vi is a screen editor. This means that it takes up almost the entire screen, displaying part of the file on each screen line, except for the last line of the screen. The last line of the screen is used for you to give commands to .IR \&vi , and for .I \&vi to give information to you. .PP The other fact that you need to understand is that .I \&vi is a modeful editor, i.e. you are either entering text or you are executing commands, and you have to be in the right mode to do one or the other. You will be in command mode when you first start editing a file. There are commands that switch you into input mode. There is only one key that takes you out of input mode, and that is the key. (Key names are written using less-than and greater-than signs, e.g. means the ``escape'' key, usually labeled ``esc'' on your terminal's keyboard.) If you're ever confused as to which mode you're in, keep entering the key until .I \&vi beeps at you. (Generally, .I \&vi will beep at you if you try and do something that's not allowed. It will also display error messages.) .PP To start editing a file, enter the command ``vi file_name''. The command you should enter as soon as you start editing is ``:set verbose showmode''. This will make the editor give you verbose error messages and display the current mode at the bottom of the screen. .PP The commands to move around the file are: .TP .B h Move the cursor left one character. .TP .B j Move the cursor down one line. .TP .B k Move the cursor up one line. .TP .B l Move the cursor right one character. .TP .B The cursor arrow keys should work, too. .TP .B /text Search for the string ``text'' in the file, and move the cursor to its first character. .PP The commands to enter new text are: .TP .B a Append new text, .I after the cursor. .TP .B i Insert new text, .I before the cursor. .TP .B o Open a new line below the line the cursor is on, and start entering text. .TP .B O Open a new line above the line the cursor is on, and start entering text. .TP .B Once you've entered input mode using the one of the .BR \&a , .BR \&i , .BR \&O or .B \&o commands, use .B to quit entering text and return to command mode. .PP The commands to copy text are: .TP .B yy Copy the line the cursor is on. .TP .B p Append the copied line after the line the cursor is on. .PP The commands to delete text are: .TP .B dd Delete the line the cursor is on. .TP .B x Delete the character the cursor is on. .PP The commands to write the file are: .TP .B :w Write the file back to the file with the name that you originally used as an argument on the .I \&vi command line. .TP .B ":w file_name" Write the file back to the file with the name ``file_name''. .PP The commands to quit editing and exit the editor are: .TP .B :q Quit editing and leave vi (if you've modified the file, but not saved your changes, .I \&vi will refuse to quit). .TP .B :q! Quit, discarding any modifications that you may have made. .PP One final caution. Unusual characters can take up more than one column on the screen, and long lines can take up more than a single screen line. The above commands work on ``physical'' characters and lines, i.e. they affect the entire line no matter how many screen lines it takes up and the entire character no matter how many screen columns it takes up. .SH VI COMMANDS The following section describes the commands available in the command mode of the .I \&vi editor.

See the .I \&vi/ex Reference manual section entitled ``Recovery'' for more information. .TP SIGINT When an interrupt occurs, the current operation is halted, and the editor returns to the command level. If interrupted during text input, the text already input is resolved into the file as if the text input had been normally terminated. .TP SIGWINCH The screen is resized. See the .I \&vi/ex Reference manual section entitled ``Sizing the Screen'' for more information. .TP SIGCONT .TP SIGQUIT .TP SIGTSTP .I \&Vi/ex ignores these signals. .SH FILES .TP /bin/sh The default user shell. .TP /etc/vi.exrc System-wide vi startup file. .TP /tmp Temporary file directory. .TP /var/tmp/vi.recover The default recovery file directory. .TP $HOME/.nexrc 1st choice for user's home directory startup file. .TP $HOME/.exrc 2nd choice for user's home directory startup file. .TP \&.nexrc 1st choice for local directory startup file. .TP \&.exrc 2nd choice for local directory startup file. .SH SEE ALSO .IR ctags (1), .IR more (1), .IR curses (3), .IR dbopen (3) .sp The ``Vi Quick Reference'' card. .sp ``An Introduction to Display Editing with Vi'', found in the ``UNIX User's Manual Supplementary Documents'' section of both the 4.3BSD and 4.4BSD manual sets.

DDEESSCCRRIIPPTTIIOONN _V_i is a screen oriented text editor. _E_x is a line-ori- ented text editor. _E_x and _v_i are different interfaces to the same program, and it is possible to switch back and forth during an edit session. _V_i_e_w is the equivalent of using the --RR (read-only) option of _v_i. This manual page is the one provided with the _n_e_x_/_n_v_i ver- sions of the _e_x_/_v_i text editors. _N_e_x_/_n_v_i are intended as bug-for-bug compatible replacements for the original Fourth Berkeley Software Distribution (4BSD) _e_x and _v_i programs. For the rest of this manual page, _n_e_x_/_n_v_i is used only when it's necessary to distinguish it from the historic implementations of _e_x_/_v_i. This manual page is intended for users already familiar with _e_x_/_v_i. Anyone else should almost certainly read a good tutorial on the editor before this manual page. If you're in an unfamiliar environment, and you absolutely have to get work done immediately, read the section after the options description, entitled ``Fast Startup''. It's probably enough to get you going. The following options are available: --cc Execute ccmmdd immediately after starting the edit session. Particularly useful for initial position- ing in the file, however ccmmdd is not limited to positioning commands. This is the POSIX 1003.2 interface for the historic ``+cmd'' syntax. _N_e_x_/_n_v_i supports both the old and new syntax. --ee Start editing in ex mode, as if the command name were _e_x. --FF Don't copy the entire file when first starting to edit. (The default is to make a copy in case some- one else modifies the file during your edit ses- sion.) --ll Start editing with the lisp and showmatch options set. --RR Start editing in read-only mode, as if the command name was _v_i_e_w, or the rreeaaddoonnllyy option was set. --rr Recover the specified files, or, if no files are specified, list the files that could be recovered. If no recoverable files by the specified name exist, the file is edited as if the --rr option had not been specified. --SS Run with the sseeccuurree edit option set, disallowing all access to external programs. --ss Enter batch mode; applicable only to _e_x edit ses- sions. Batch mode is useful when running _e_x scripts. Prompts, informative messages and other user oriented message are turned off, and no startup files or environmental variables are read. This is the POSIX 1003.2 interface for the historic ``-'' argument. _N_e_x_/_n_v_i supports both the old and new syntax. --tt Start editing at the specified tag. (See _c_t_a_g_s(1)). --ww Set the initial window size to the specified number of lines. --vv Start editing in vi mode, as if the command name was _v_i or _v_i_e_w. Command input for _e_x_/_v_i is read from the standard input. In the _v_i interface, it is an error if standard input is not a terminal. In the _e_x interface, if standard input is not a terminal, _e_x will read commands from it regardless, however, the session will be a batch mode session, exactly as if the --ss option had been specified. _E_x_/_v_i exits 0 on success, and greater than 0 if an error occurs. FFAASSTT SSTTAARRTTUUPP This section will tell you the minimum amount that you need to do simple editing tasks using _v_i. If you've never used any screen editor before, you're likely to have prob- lems even with this simple introduction. In that case you should find someone that already knows _v_i and have them walk you through this section. _V_i is a screen editor. This means that it takes up almost the entire screen, displaying part of the file on each screen line, except for the last line of the screen. The last line of the screen is used for you to give commands to _v_i, and for _v_i to give information to you. The other fact that you need to understand is that _v_i is a modeful editor, i.e. you are either entering text or you are executing commands, and you have to be in the right mode to do one or the other. You will be in command mode when you first start editing a file. There are commands that switch you into input mode. There is only one key that takes you out of input mode, and that is the key. (Key names are written using less-than and greater- than signs, e.g. means the ``escape'' key, usu- ally labeled ``esc'' on your terminal's keyboard.) If you're ever confused as to which mode you're in, keep entering the key until _v_i beeps at you. (Gener- ally, _v_i will beep at you if you try and do something that's not allowed. It will also display error messages.) To start editing a file, enter the command ``vi file_name''. The command you should enter as soon as you start editing is ``:set verbose show- mode''. This will make the editor give you verbose error messages and display the current mode at the bottom of the screen. The commands to move around the file are: hh Move the cursor left one character. jj Move the cursor down one line. kk Move the cursor up one line. ll Move the cursor right one character. <> The cursor arrow keys should work, too. //tteexxtt<> Search for the string ``text'' in the file, and move the cursor to its first character. The commands to enter new text are: aa Append new text, _a_f_t_e_r the cursor. ii Insert new text, _b_e_f_o_r_e the cursor. oo Open a new line below the line the cursor is on, and start entering text. OO Open a new line above the line the cursor is on, and start entering text. <> Once you've entered input mode using the one of the aa, ii, OO or oo commands, use <> to quit enter- ing text and return to command mode. The commands to copy text are: yyyy Copy the line the cursor is on. pp Append the copied line after the line the cursor is on. The commands to delete text are: dddd Delete the line the cursor is on. xx Delete the character the cursor is on. The commands to write the file are: ::ww<> Write the file back to the file with the name that you originally used as an argument on the _v_i com- mand line. ::ww ffiillee__nnaammee<> Write the file back to the file with the name ``file_name''. The commands to quit editing and exit the editor are: ::qq<> Quit editing and leave vi (if you've modified the file, but not saved your changes, _v_i will refuse to quit). ::qq!!<> Quit, discarding any modifications that you may have made. One final caution. Unusual characters can take up more than one column on the screen, and long lines can take up more than a single screen line. The above commands work on ``physical'' characters and lines, i.e. they affect the entire line no matter how many screen lines it takes up and the entire character no matter how many screen columns it takes up.

Set the window size if the baud rate is equal to 1200 baud. ww99660000 [[nnoo ddeeffaauulltt]] _V_i only. Set the window size if the baud rate is greater than 1200 baud. wwaarrnn [[oonn]] _E_x only. This option causes a warning message to the terminal if the file has been modified, since it was last written, before a !! command. wwiinnddooww,, ww,, wwii [[eennvviirroonnmmeenntt vvaarriiaabbllee LLIINNEESS]] Set the window size for the screen. wwiinnddoowwnnaammee [[ooffff]] Change the icon/window name to the current file name even if it can't be restored on editor exit. wwrraapplleenn,, wwll [[00]] _V_i only. Break lines automatically, the specified number of columns from the left-hand margin. If both the wwrraapplleenn and wwrraappmmaarrggiinn edit options are set, the wwrraappmmaarrggiinn value is used. wwrraappmmaarrggiinn,, wwmm [[00]] _V_i only. Break lines automatically, the specified number of columns from the right-hand margin. If both the wwrraapplleenn and wwrraappmmaarrggiinn edit options are set, the wwrraappmmaarrggiinn value is used. wwrraappssccaann,, wwss [[oonn]] Set searches to wrap around the end or beginning of the file. wwrriitteeaannyy,, wwaa [[ooffff]] Turn off file-overwriting checks. EENNVVIIRROONNMMEENNTT VVAARRIIAABBLLEESS _C_O_L_U_M_N_S The number of columns on the screen. This value overrides any system or terminal specific values. If the _C_O_L_U_M_N_S environmental variable is not set when _e_x_/_v_i runs, or the ccoolluummnnss option is explic- itly reset by the user, _e_x_/_v_i enters the value into the environment. _E_X_I_N_I_T A list of _e_x startup commands, read if the variable _N_E_X_I_N_I_T is not set. _H_O_M_E The user's home directory, used as the initial directory path for the startup ``$_H_O_M_E/.nexrc'' and ``$_H_O_M_E/.exrc'' files. This value is also used as the default directory for the _v_i ccdd command. _L_I_N_E_S The number of rows on the screen. This value over- rides any system or terminal specific values. If the _L_I_N_E_S environmental variable is not set when _e_x_/_v_i runs, or the lliinneess option is explicitly reset by the user, _e_x_/_v_i enters the value into the envi- ronment. _N_E_X_I_N_I_T A list of _e_x startup commands. _S_H_E_L_L The user's shell of choice (see also the sshheellll option). _T_E_R_M The user's terminal type. The default is the type ``unknown''. If the _T_E_R_M environmental variable is not set when _e_x_/_v_i runs, or the tteerrmm option is explicitly reset by the user, _e_x_/_v_i enters the value into the environment. _T_M_P_D_I_R The location used to stored temporary files (see also the ddiirreeccttoorryy edit option). AASSYYNNCCHHRROONNOOUUSS EEVVEENNTTSS SIGALRM _V_i_/_e_x uses this signal for periodic backups of file modifications and to display ``busy'' messages when operations are likely to take a long time. SIGHUP SIGTERM If the current buffer has changed since it was last written in its entirety, the editor attempts to save the modified file so it can be later recov- ered. See the _v_i_/_e_x Reference manual section enti- tled ``Recovery'' for more information. SIGINT When an interrupt occurs, the current operation is halted, and the editor returns to the command level. If interrupted during text input, the text already input is resolved into the file as if the text input had been normally terminated. SIGWINCH The screen is resized. See the _v_i_/_e_x Reference manual section entitled ``Sizing the Screen'' for more information. SIGCONT SIGQUIT SIGTSTP _V_i_/_e_x ignores these signals. FFIILLEESS /bin/sh The default user shell. /etc/vi.exrc System-wide vi startup file. /tmp Temporary file directory. /var/tmp/vi.recover The default recovery file directory. $HOME/.nexrc 1st choice for user's home directory startup file. $HOME/.exrc 2nd choice for user's home directory startup file. .nexrc 1st choice for local directory startup file. .exrc 2nd choice for local directory startup file. SSEEEE AALLSSOO _c_t_a_g_s(1), _m_o_r_e(1), _c_u_r_s_e_s(3), _d_b_o_p_e_n(3) The ``Vi Quick Reference'' card. ``An Introduction to Display Editing with Vi'', found in the ``UNIX User's Manual Supplementary Documents'' section of both the 4.3BSD and 4.4BSD manual sets. This document is the closest thing available to an introduction to the _v_i screen editor. ``Ex Reference Manual (Version 3.7)'', found in the ``UNIX User's Manual Supplementary Documents'' section of both the 4.3BSD and 4.4BSD manual sets. This document is the final reference for the _e_x editor, as distributed in most historic 4BSD and System V systems. ``Edit: A tutorial'', found in the ``UNIX User's Manual Supplementary Documents'' section of the 4.3BSD manual set. This document is an introduction to a simple version of the _e_x screen editor. ``Ex/Vi Reference Manual'', found in the ``UNIX User's Manual Supplementary Documents'' section of the 4.4BSD manual set. This document is the final reference for the _n_e_x_/_n_v_i text editors, as distributed in 4.4BSD and 4.4BSD- Lite. _R_o_f_f source for all of these documents is distributed with _n_e_x_/_n_v_i in the _n_v_i_/_U_S_D_._d_o_c directory of the _n_e_x_/_n_v_i source code. The files ``autowrite'', ``input'', ``quoting'' and ``structures'' found in the _n_v_i_/_d_o_c_s_/_i_n_t_e_r_n_a_l_s directory of the _n_e_x_/_n_v_i source code. HHIISSTTOORRYY The _n_e_x_/_n_v_i replacements for the _e_x_/_v_i editor first appeared in 4.4BSD. SSTTAANNDDAARRDDSS _N_e_x_/_n_v_i is close to IEEE Std1003.2 (``POSIX''). That doc- ument differs from historical _e_x_/_v_i practice in several places; there are changes to be made on both sides. 1Q1 VI(1)

This character is normally @LI{}. However, whatever character is set for the current terminal is supported as well as @LI{}. @cindex "line" @IP{line} A single-line address, given in any of the forms described in the section entitled @QB{Ex Addressing} . The default for @LI{line}is the current line. @cindex "range" @IP{range} A line, or a pair of line addresses, separated by a comma or semicolon. (See the section entitled @QB{Ex Addressing} for more information.) The default for range is the current line @emph{only}, i.e. @QT{.,.}. A percent sign @PQ{%} stands for the range @QT{1,$}. The starting address must be less than, or equal to, the ending address. @cindex "count" @IP{count} A positive integer, specifying the number of lines to be affected by the command; the default is 1. Generally, a count past the end-of-file may be specified, e.g. the command @QT{p 3000} in a 10 line file is acceptable, and will print from the current line through the last line in the file. @cindex "flags" @IP{flags} One or more of the characters @QQ{#}, @QQ{p}, and @QQ{l}. When a command that accepts these flags completes, the addressed line(s) are written out as if by the corresponding @CO{#}, @CO{l} or @CO{p} commands. In addition, any number of @QT{+} or @QT{-} characters can be specified before, after, or during the flags, in which case the line written is not necessarily the one affected by the command, but rather the line addressed by the offset address specified. The default for @LI{flags}is none. @cindex "file" @IP{file} A pattern used to derive a pathname; the default is the current file. File names are subjected to normal @XR{sh,1} word expansions. @end itemize Anywhere a file name is specified, it is also possible to use the special string @QT{/tmp}. This will be replaced with a temporary file name which can be used for temporary work, e.g. @QT{:e /tmp} creates and edits a new file. If both a count and a range are specified for commands that use either, the starting line for the command is the @emph{last} line addressed by the range, and @LI{count}- 1 subsequent lines are affected by the command, e.g. the command @QT{2,3p4} prints out lines 3, 4, 5 and 6. When only a line or range is specified, with no command, the implied command is either a @CO{list}, @CO{number} or @CO{print} command. The command used is the most recent of the three commands to have been used (including any use as a flag). If none of these commands have been used before, the @CO{print} command is the implied command. When no range or count is specified and the command line is a blank line, the current line is incremented by 1 and then the current line is displayed. Zero or more whitespace characters may precede or follow the addresses, count, flags, or command name. Any object following a command name (such as buffer, file, etc.), that begins with an alphabetic character, should be separated from the command name by at least one whitespace character. Any character, including @LI{}, @QT{%} and @QT{#} retain their literal value when preceded by a backslash. @chapter Ex Commands The following section describes the commands available in the @CO{ex} editor. In each entry below, the tag line is a usage synopsis for the command. Each command can be entered as the abbreviation (those characters in the synopsis command word preceding the @QQ{[} character), the full command (all characters shown for the command word, omitting the @QQ{[} and @QQ{]} characters), or any leading subset of the full command down to the abbreviation. For example, the args command (shown as @QT{ar[gs]} in the synopsis) can be entered as @QT{ar}, @QT{arg} or @QT{args}. Each @CO{ex} command described below notes the new current line after it is executed, as well as any options that affect the command. @cindex DOUBLEQUOTE @deftypefn Command {} {"} A comment. Command lines beginning with the double-quote character @PQ{"} are ignored. This permits comments in editor scripts and startup files. @end deftypefn @cindex "" @cindex "" @deftypefn Command {} {} @deftypefnx Command {} {} Scroll the screen. Write the next N lines, where N is the value of the @OP{scroll} option. The command is the end-of-file terminal character, which may be different on different terminals. Traditionally, it is the @LI{}key. @sp 1 Historically, the @CO{eof} command ignored any preceding count, and the @LI{}character was ignored unless it was entered as the first character of the command. This implementation treats it as a command @emph{only} if entered as the first character of the command line, and otherwise treats it as any other character. @table @asis @item Line: Set to the last line written. @item Options: Affected by the @OP{scroll} option. @end table @end deftypefn @cindex "!" @deftypefn Command {} {!} {argument(s)} @deftypefnx Command {} {[range]!} {argument(s)} Execute a shell command, or filter lines through a shell command. In the first synopsis, the remainder of the line after the @QT{!} character is passed to the program named by the @OP{shell} option, as a single argument. @sp 1 Within the rest of the line, @QT{%} and @QT{#} are expanded into the current and alternate pathnames, respectively. The character @QT{!} is expanded with the command text of the previous @CO{!} command. (Therefore, the command @CO{!!} repeats the previous @CO{!} command.) The special meanings of @QT{%}, @QT{#}, and @QT{!} can be overridden by escaping them with a backslash. If no @CO{!} or @CO{:!} command has yet been executed, it is an error to use an unescaped @QT{!} character. The @CO{!} command does @emph{not} do shell expansion on the strings provided as arguments. If any of the above expansions change the command the user entered, the command is redisplayed at the bottom of the screen. @sp 1 @CO{Ex} then executes the program named by the @OP{shell} option, with a @strong{-c} flag followed by the arguments (which are bundled into a single argument). @sp 1 The @CO{!} command is permitted in an empty file. @sp 1 If the file has been modified since it was last completely written, the @CO{!} command will warn you. @sp 1 A single @QT{!} character is displayed when the command completes. @sp 1 In the second form of the @CO{!} command, the remainder of the line after the @QT{!} is passed to the program named by the @OP{shell} option, as described above. The specified lines are passed to the program as standard input, and the standard and standard error output of the program replace the original lines. @table @asis @item Line: Unchanged if no range was specified, otherwise set to the first line of the range. @item Options: Affected by the @OP{shell} and @OP{warn} options. @end table @end deftypefn @cindex "#" @deftypefn Command {[range]} {#} {[count] [flags]} @cindex "number" @deftypefnx Command {[range]} {nu[mber]} {[count] [flags]} Display the selected lines, each preceded with its line number. @sp 1 The line number format is @QQ{%6d}, followed by two spaces. @table @asis @item Line: Set to the last line displayed. @item Options: Affected by the @OP{list} option. @end table @end deftypefn @cindex "@@" @deftypefn Command {@@} {buffer} @cindex "*" @deftypefnx Command {} {*} {buffer} Execute a buffer. Each line in the named buffer is executed as an @CO{ex} command. If no buffer is specified, or if the specified buffer is @QT{@@} or @QT{*}, the last buffer executed is used. @end deftypefn @cindex < @deftypefn Command {[range]} {<[< ...]} {[count] [flags]} Shift lines left or right. The specified lines are shifted to the left (for the @CO{<} command) or right (for the @CO{>} command), by the number of columns specified by the @OP{shiftwidth} option. Only leading whitespace characters are deleted when shifting left; once the first column of the line contains a nonblank character, the @CO{shift} command will succeed, but the line will not be modified. @sp 1 If the command character @CO{<} or @CO{>} is repeated more than once, the command is repeated once for each additional command character. @table @asis @item Line: If the current line is set to one of the lines that are affected by the command, it is unchanged. Otherwise, it is set to the first nonblank character of the lowest numbered line shifted. @item Options: Affected by the @OP{shiftwidth} option. @end table @end deftypefn @cindex = @deftypefn Command {[line]} {=} {[flags]} Display the line number of @LI{line}(which defaults to the last line in the file). @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex > @deftypefn Command {[range]} {>[> ...]} {[count] [flags]} Shift right. The specified lines are shifted to the right by the number of columns specified by the @OP{shiftwidth} option, by inserting tab and space characters. Empty lines are not changed. @sp 1 If the command character @QT{>} is repeated more than once, the command is repeated once for each additional command character. @table @asis @item Line: Set to the last line modified by the command. @item Options: Affected by the @OP{shiftwidth} option. @end table @end deftypefn @cindex abbrev @deftypefn Command {} {ab[brev]} {lhs rhs} Add an abbreviation to the current abbreviation list. When inserting text in @CO{vi}, each time a non-word character is entered after a word character, a set of characters ending at the word character are checked for a match with @LI{lhs}. If a match is found, they are replaced with @LI{rhs}. The set of characters that are checked for a match are defined as follows, for inexplicable historical reasons. If only one or two characters were entered before the non-word character that triggered the check, and after the beginning of the insertion, or the beginning of the line or the file, or the last @LI{}character that was entered, then the one or the both characters are checked for a match. Otherwise, the set includes both characters, as well as the characters that precede them that are the same word class (i.e. word or non-word) as the @strong{second} to last character entered before the non-word character that triggered the check, back to the first @LI{}character, the beginning of the insertion, or the beginning of the line or the file. @sp 1 For example, the abbreviations: @sp 1 @multitable {:abbreviate} {/*#i} {/********************} @item :abbreviate @tab abc @tab ABC @item :abbreviate @tab #i @tab #include @item :abbreviate @tab /*#i @tab /*#include @end multitable will all work, while the abbreviations: @sp 1 @multitable {:abbreviate} {/*#i} {/********************} @item :abbreviate @tab a#i @tab A#include @item :abbreviate @tab /* @tab /******************** @end multitable will not work, and are not permitted by @CO{nvi}. @sp 1 To keep the abbreviation expansion from happening, the character immediately following the @LI{lhs}characters should be quoted with a @LI{}character. @sp 1 The replacement @LI{rhs}is itself subject to both further abbreviation expansion and further map expansion. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex append @deftypefn Command {[line]} {a[ppend][!]} The input text is appended to the specified line. If line 0 is specified, the text is inserted at the beginning of the file. Set to the last line input. If no lines are input, then set to @LI{line}, or to the first line of the file if a @LI{line}of 0 was specified. Following the command name with a @QT{!} character causes the @OP{autoindent} option to be toggled for the duration of the command. @table @asis @item Line: Unchanged. @item Options: Affected by the @OP{autoindent} and @OP{number} options. @end table @end deftypefn @cindex args @deftypefn Command {} {ar[gs]} Display the argument list. The current argument is displayed inside of @QT{[} and @QT{]} characters. The argument list is the list of operands specified on startup, which can be replaced using the @CO{next} command. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex bg @deftypefn Command {} {bg} @CO{Vi} mode only. Background the current screen. The screen is unchanged, but is no longer accessible and disappears from the display. Use the @CO{fg} command to bring the screen back to the display foreground. @table @asis @item Line: Set to the current line when the screen was last edited. @item Options: None. @end table @end deftypefn @cindex change @deftypefn Command {[range]} {c[hange][!]} {[count]} Replace the lines with input text. Following the command name with a @QT{!} character causes the @OP{autoindent} option to be toggled for the duration of the command. @table @asis @item Line: Set to the last line input, or, if no lines were input, set to the line before the target line, or to the first line of the file if there are no lines preceding the target line. @item Options: Affected by the @OP{autoindent} and @OP{number} options. @end table @cindex cd @end deftypefn @cindex chdir @deftypefn Command {} {chd[ir][!]} {[directory]} @deftypefnx Command {} {cd[!]} {[directory]} Change the current working directory. The @LI{directory}argument is subjected to @XR{sh,1} word expansions. When invoked with no directory argument and the @LI{HOME}environment variable is set, the directory named by the @LI{HOME}environment variable becomes the new current directory. Otherwise, the new current directory becomes the directory returned by the @XR{getpwent,3} routine. @sp 1 The @CO{chdir} command will fail if the file has been modified since the last complete write of the file. You can override this check by appending a @QT{!} character to the command. @table @asis @item Line: Unchanged. @item Options: Affected by the @OP{cdpath} option. @end table @cindex copy @end deftypefn @cindex t @deftypefn Command {[range]} {co[py]} {line [flags]} @deftypefnx Command {[range]} {t} {line [flags]} Copy the specified lines (range) after the destination line. Line 0 may be specified to insert the lines at the beginning of the file. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex cscope @deftypefn Command {} {cs[cope]} {command [args]} Execute a @CO{cscope} command. For more information, see the section of the reference manual entitled @QB{Tags, Tag Stacks, and Cscope} . @end deftypefn @cindex delete @deftypefn Command {[range]} {d[elete]} {[buffer] [count] [flags]} Delete the lines from the file. The deleted text is saved in the specified buffer, or, if no buffer is specified, in the unnamed buffer. If the command name is followed by a letter that could be interpreted as either a buffer name or a flag value (because neither a @LI{count}or @LI{flags}values were given), @CO{ex} treats the letter as a @LI{flags}value if the letter immediately follows the command name, without any whitespace separation. If the letter is preceded by whitespace characters, it treats it as a buffer name. @table @asis @item Line: Set to the line following the deleted lines, or to the last line if the deleted lines were at the end. @item Options: None. @end table @end deftypefn @cindex display @deftypefn Command {} {di[splay]} {b[uffers] | c[onnections] | s[creens] | t[ags]} Display buffers, @CO{cscope} connections, screens or tags. The @CO{display} command takes one of three additional arguments, which are as follows: @table @asis @item b[uffers] Display all buffers (including named, unnamed, and numeric) that contain text. @item c[onnections] Display the source directories for all attached @CO{cscope} databases. @item s[creens] Display the file names of all background screens. @item t[ags] Display the tags stack. @end table @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex edit @deftypefn Command {} {e[dit][!]} {[+cmd] [file]} @deftypefnx Command {} {ex[!]} {[+cmd] [file]} @deftypefnx Command {} {vs[plit][!]} {[+cmd] [file]} Edit a different file. If the current buffer has been modified since the last complete write, the command will fail. You can override this by appending a @QT{!} character to the command name. @sp 1 If the @QT{+cmd} option is specified, that @CO{ex} command will be executed in the new file. Any @CO{ex} command may be used, although the most common use of this feature is to specify a line number or search pattern to set the initial location in the new file. @sp 1 Capitalizing the first letter of the command, i.e., @CO{Edit} or @CO{Ex}, while in @CO{vi} mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. @cindex vertical split @cindex splitting, vertically @CO{vsplit} is similar, but the screen will be split vertically to produce the new screen, rather than horizontally. @table @asis @item Line: If you have previously edited the file, the current line will be set to your last position in the file. If that position does not exist, or you have not previously edited the file, the current line will be set to the first line of the file if you are in @CO{vi} mode, and the last line of the file if you are in @CO{ex}. @item Options: None. @end table @end deftypefn @cindex exusage @deftypefn Command {} {exu[sage]} {[command]} Display usage for an @CO{ex} command. If @LI{command}is specified, a usage statement for that command is displayed. Otherwise, usage statements for all @CO{ex} commands are displayed. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex file @deftypefn Command {} {f[ile]} {[file]} Display and optionally change the file name. If a file name is specified, the current pathname is changed to the specified name. The current pathname, the number of lines, and the current position in the file are displayed. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex fg @deftypefn Command {} {fg} {[name]} @CO{Vi} mode only. Foreground the specified screen. If the argument name doesn't exactly match the name of a file displayed by a background screen, it is compared against the last component of each of the file names. If no background screen is specified, the first background screen is foregrounded. @sp 1 By default, foregrounding causes the current screen to be swapped with the backgrounded screen. Capitalizing the first letter of the command, i.e. @CO{Fg}, will foreground the backgrounded screen in a new screen instead of swapping it with the current screen. @table @asis @item Line: Set to the current line when the screen was last edited. @item Options: None. @end table @end deftypefn @cindex global @deftypefn Command {[range]} {g[lobal]} {/pattern/ [commands]} @cindex v @deftypefnx Command {[range]} {v} {/pattern/ [commands]} Apply commands to lines matching (or not matching) a pattern. The lines within the given range that match @PQ{g[lobal]}, or do not match @PQ{v} the given pattern are selected. Then, the specified @CO{ex} command(s) are executed with the current line @PQ{.} set to each selected line. If no range is specified, the entire file is searched for matching, or not matching, lines. @sp 1 Multiple commands can be specified, one per line, by escaping each @LI{}character with a backslash, or by separating commands with a @QT{|} character. If no commands are specified, the command defaults to the @CO{print} command. @sp 1 For the @CO{append}, @CO{change} and @CO{insert} commands, the input text must be part of the global command line. In this case, the terminating period can be omitted if it ends the commands. @sp 1 The @CO{visual} command may also be specified as one of the @CO{ex} commands. In this mode, input is taken from the terminal. Entering a @CO{Q} command in @CO{vi} mode causes the next line matching the pattern to be selected and @CO{vi} to be reentered, until the list is exhausted. @sp 1 The @CO{global}, @CO{v} and @CO{undo} commands cannot be used as part of these commands. @sp 1 The editor options @OP{autoindent}, @OP{autoprint} and @OP{report} are turned off for the duration of the @CO{global} and @CO{v} commands. @table @asis @item Line: The last line modified. @item Options: Affected by the @OP{ignorecase} and @OP{magic} options. Turns off the @OP{autoindent}, @OP{autoprint} and @OP{report} options. @end table @end deftypefn @cindex help @deftypefn Command {} {he[lp]} Display a help message. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex insert @deftypefn Command {[line]} {i[nsert][!]} The input text is inserted before the specified line. Following the command name with a @QT{!} character causes the @OP{autoindent} option setting to be toggled for the duration of this command. @table @asis @item Line: Set to the last line input; if no lines were input, set to the line before the target line, or to the first line of the file if there are no lines preceding the target line. Affected by the @OP{autoindent} and @OP{number} options. @end table @end deftypefn @cindex join @deftypefn Command {[range]} {j[oin][!]} {[count] [flags]} Join lines of text together. @sp 1 A @LI{count}specified to the @CO{join} command specifies that the last line of the @LI{range}plus @LI{count}subsequent lines will be joined. (Note, this differs by one from the general rule where only @LI{count}- 1 subsequent lines are affected.) @sp 1 If the current line ends with a whitespace character, all whitespace is stripped from the next line. Otherwise, if the next line starts with a open parenthesis @PQ{(}, do nothing. Otherwise, if the current line ends with a question mark @PQ{?}, period @PQ{.} or exclamation point @PQ{!}, insert two spaces. Otherwise, insert a single space. @sp 1 Appending a @QT{!} character to the command name causes a simpler join with no white-space processing. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex list @deftypefn Command {[range]} {l[ist]} {[count] [flags]} Display the lines unambiguously. Tabs are displayed as @QT{^I}, and the end of the line is marked with a @QT{$} character. @table @asis @item Line: Set to the last line displayed. @item Options: Affected by the @OP{number} option. @end table @end deftypefn @cindex map @deftypefn Command {} {map[!]} {[lhs rhs]} Define or display maps (for @CO{vi} only). @sp 1 If @QT{lhs} and @QT{rhs} are not specified, the current set of command mode maps are displayed. If a @QT{!} character is appended to to the command, the text input mode maps are displayed. @sp 1 Otherwise, when the @QT{lhs} character sequence is entered in @CO{vi}, the action is as if the corresponding @QT{rhs} had been entered. If a @QT{!} character is appended to the command name, the mapping is effective during text input mode, otherwise, it is effective during command mode. This allows @QT{lhs} to have two different macro definitions at the same time: one for command mode and one for input mode. @sp 1 Whitespace characters require escaping with a @LI{}character to be entered in the @LI{lhs}string in visual mode. @sp 1 Normally, keys in the @LI{rhs}string are remapped (see the @OP{remap} option), and it is possible to create infinite loops. However, keys which map to themselves are not further remapped, regardless of the setting of the @OP{remap} option. For example, the command @QT{:map n nz.} maps the @QT{n} key to the @CO{n} and @CO{z} commands. @sp 1 To exit an infinitely looping map, use the terminal @LI{}character. @table @asis @item Line: Unchanged. @item Options: Affected by the @OP{remap} option. @end table @cindex mark @end deftypefn @cindex k @deftypefn Command {[line]} {ma[rk]} {} @deftypefnx Command {[line]} {k} {} Mark the line with the mark @LI{}. The expressions @QT{'} and @QT{`} can then be used as an address in any command that uses one. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex move @deftypefn Command {[range]} {m[ove]} {line} Move the specified lines after the target line. A target line of 0 places the lines at the beginning of the file. @table @asis @item Line: Set to the first of the moved lines. @item Options: None. @end table @end deftypefn @cindex mkexrc @deftypefn Command {} {mk[exrc][!]} {file} Write the abbreviations, editor options and maps to the specified file. Information is written in a form which can later be read back in using the @CO{ex} @CO{source} command. If @LI{file}already exists, the @CO{mkexrc} command will fail. This check can be overridden by appending a @QT{!} character to the command. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex next @deftypefn Command {} {n[ext][!]} {[file ...]} Edit the next file from the argument list. The @CO{next} command will fail if the file has been modified since the last complete write. This check can be overridden by appending the @QT{!} character to the command name. The argument list can optionally be replaced by specifying a new one as arguments to this command. In this case, editing starts with the first file on the new list. @sp 1 Capitalizing the first letter of the command, i.e. @CO{Next}, while in @CO{vi} mode, will set the argument list and edit the file in a new screen. In this case, any modifications to the current file are ignored. @table @asis @item Line: Set as described for the @CO{edit} command. @item Options: Affected by the options @OP{autowrite} and @OP{writeany}. @end table @end deftypefn @cindex open @deftypefn Command {[line]} {o[pen]} {/pattern/ [flags]} Enter open mode. Open mode is the same as being in @CO{vi}, but with a one-line window. All the standard @CO{vi} commands are available. If a match is found for the optional RE argument, the cursor is set to the start of the matching pattern. @sp 1 @emph{This command is not yet implemented.} @table @asis @item Line: Unchanged, unless the optional RE is specified, in which case it is set to the line where the matching pattern is found. @item Options: Affected by the @OP{open} option. @end table @end deftypefn @cindex preserve @deftypefn Command {} {pre[serve]} Save the file in a form that can later be recovered using the @CO{ex} @strong{-r} option. When the file is preserved, an email message is sent to the user. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex previous @deftypefn Command {} {prev[ious][!]} Edit the previous file from the argument list. The @CO{previous} command will fail if the file has been modified since the last complete write. This check can be overridden by appending the @QT{!} character to the command name. @sp 1 Capitalizing the first letter of the command, i.e. @CO{Previous}, while in @CO{vi} mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. @table @asis @item Line: Set as described for the @CO{edit} command. @item Options: Affected by the options @OP{autowrite} and @OP{writeany}.

If a buffer is specified, its contents are appended to the line, otherwise, the contents of the unnamed buffer are used. @table @asis @item Line: Set to the line after the current line. @item Options: None. @end table @end deftypefn @cindex quit @deftypefn Command {} {q[uit][!]} End the editing session. If the file has been modified since the last complete write, the @CO{quit} command will fail. This check may be overridden by appending a @QT{!} character to the command. @sp 1 If there are more files to edit, the @CO{quit} command will fail. Appending a @QT{!} character to the command name or entering two @CO{quit} commands (i.e. @CO{wq}, @CO{quit}, @CO{xit} or @CO{ZZ}) in a row) will override this check and the editor will exit. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex read @deftypefn Command {[line]} {r[ead][!]} {[file]} Read a file. A copy of the specified file is appended to the line. If @LI{line}is 0, the copy is inserted at the beginning of the file. If no file is specified, the current file is read; if there is no current file, then @LI{file}becomes the current file. If there is no current file and no @LI{file}is specified, then the @CO{read} command will fail. @sp 1 If @LI{file}is preceded by a @QT{!} character, @LI{file}is treated as if it were a shell command, and passed to the program named by the @OP{shell} edit option. The standard and standard error outputs of that command are read into the file after the specified line. The special meaning of the @QT{!} character can be overridden by escaping it with a backslash @PQ{\e} character. @table @asis @item Line: When executed from @CO{ex}, the current line is set to the last line read. When executed from @CO{vi}, the current line is set to the first line read. @item Options: None. @end table @end deftypefn @cindex recover @deftypefn Command {} {rec[over]} {file} Recover @LI{file}if it was previously saved. If no saved file by that name exists, the @CO{recover} command behaves equivalently to the @CO{edit} command. @table @asis @item Line: Set as described for the @CO{edit} command. @item Options: None. @end table @end deftypefn @cindex resize @deftypefn Command {} {res[ize]} {[+|-]size} @CO{Vi} mode only. Grow or shrink the current screen. If @LI{size}is a positive, signed number, the current screen is grown by that many lines. If @LI{size}is a negative, signed number, the current screen is shrunk by that many lines. If @LI{size}is not signed, the current screen is set to the specified @LI{size}. Applicable only to split screens. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex rewind @deftypefn Command {} {rew[ind][!]} Rewind the argument list. If the current file has been modified since the last complete write, the @CO{rewind} command will fail. This check may be overridden by appending the @QT{!} character to the command. @sp 1 Otherwise, the current file is set to the first file in the argument list. @table @asis @item Line: Set as described for the @CO{edit} command. @item Options: Affected by the @OP{autowrite} and @OP{writeany} options. @end table @end deftypefn @cindex set @deftypefn Command {} {se[t]} {[option[=[value]] ...] [nooption ...] [option? ...] [all]} Display or set editor options. When no arguments are specified, the editor option @OP{term}, and any editor options whose values have been changed from the default settings are displayed. If the argument @LI{all}is specified, the values of all of editor options are displayed. @sp 1 Specifying an option name followed by the character @QT{?} causes the current value of that option to be displayed. The @QT{?} can be separated from the option name by whitespace characters. The @QT{?} is necessary only for Boolean valued options. Boolean options can be given values by the form @QT{set option} to turn them on, or @QT{set nooption} to turn them off. String and numeric options can be assigned by the form @QT{set option=value}. Any whitespace characters in strings can be included literally by preceding each with a backslash. More than one option can be set or listed by a single set command, by specifying multiple arguments, each separated from the next by whitespace characters. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex shell @deftypefn Command {} {sh[ell]} Run the shell program.

Editing is resumed when that program exits. @table @asis @item Line: Unchanged. @item Options: Affected by the @OP{shell} option. @end table @end deftypefn @cindex source @deftypefn Command {} {so[urce]} {file} Read and execute @CO{ex} commands from a file. @CO{Source} commands may be nested. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex substitute @deftypefn Command {[range]} {s[ubstitute]} {[/pattern/replace/] [options] [count] [flags]} @cindex & @deftypefnx Command {[range]} {&} {[options] [count] [flags]} @cindex ~ @deftypefnx Command {[range]} {~} {[options] [count] [flags]} Make substitutions. Replace the first instance of @LI{pattern}with the string @LI{replace}on the specified line(s). If the @QT{/pattern/repl/} argument is not specified, the @QT{/pattern/repl/} from the previous @CO{substitute} command is used. Any character other than an alphabetic, numeric, or backslash character may be used as the delimiter. @sp 1 If @LI{options}includes the letter @QT{c} (confirm), you will be prompted for confirmation before each replacement is done. An affirmative response (in English, a @QT{y} character) causes the replacement to be made. A quit response (in English, a @QT{q} character) causes the @CO{substitute} command to be terminated. Any other response causes the replacement not to be made, and the @CO{substitute} command continues. If @LI{options}includes the letter @QT{g} (global), all nonoverlapping instances of @LI{pattern}in the line are replaced. @sp 1 The @CO{&} version of the command is the same as not specifying a pattern or replacement string to the @CO{substitute} command, and the @QT{&} is replaced by the pattern and replacement information from the previous substitute command. @sp 1 The @CO{~} version of the command is the same as @CO{&} and @CO{s}, except that the search pattern used is the last RE used in @emph{any} command, not necessarily the one used in the last @CO{substitute} command. @sp 1 For example, in the sequence @example s/red/blue/ /green ~ @end example the @QT{~} is equivalent to @QT{s/green/blue/}. @sp 1 The @CO{substitute} command may be interrupted, using the terminal interrupt character. All substitutions completed before the interrupt are retained. @table @asis @item Line: Set to the last line upon which a substitution was made. @item Options: Affected by the @OP{ignorecase} and @OP{magic} option. @end table @end deftypefn @cindex suspend @deftypefn Command {} {su[spend][!]} @cindex stop @deftypefnx Command {} {st[op][!]} @deftypefnx Comamnd {} Suspend the edit session.

If the tag is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the @CO{tag} command will fail. This check can be overridden by appending the @QT{!} character to the command name. @sp 1 The @CO{tag} command searches for @LI{tagstring}in the tags file(s) specified by the @OP{tags} option. (See @XR{ctags,1} for more information on tags files.) @sp 1 Capitalizing the first letter of the command, i.e. @CO{Tag}, while in @CO{vi} mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. @table @asis @item Line: Set to the line indicated by the tag. @item Options: Affected by the @OP{autowrite}, @OP{taglength}, @OP{tags} and @OP{writeany} options. @end table @end deftypefn @cindex tagnext @deftypefn Command {} {tagn[ext][!]} Edit the file containing the next context for the current tag. If the context is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the @CO{tagnext} command will fail. This check can be overridden by appending the @QT{!} character to the command name. @sp 1 Capitalizing the first letter of the command, i.e. @CO{Tagnext}, while in @CO{vi} mode, will edit the file in a new screen.

If neither @LI{file}or @LI{number}is specified, the @CO{tagpop} command pops to the most recent entry on the tags stack. If @LI{file}or @LI{number}is specified, the @CO{tagpop} command pops to the most recent entry in the tags stack for that file, or numbered entry in the tags stack, respectively. (See the @CO{display} command for information on displaying the tags stack.) @sp 1 If the file has been modified since the last complete write, the @CO{tagpop} command will fail.

This check may be overridden by appending a @QT{!} character to the command name. @table @asis @item Line: Set to the line indicated by the tag. @item Options: Affected by the @OP{autowrite} and @OP{writeany} options. @end table @end deftypefn @cindex unabbrev @deftypefn Command {} {una[bbrev]} {lhs} Delete an abbreviation. Delete @LI{lhs}from the current list of abbreviations. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex undo @deftypefn Command {} {u[ndo]} Undo the last change made to the file. Changes made by @CO{global}, @CO{v}, @CO{visual} and map sequences are considered a single command. If repeated, the @CO{u} command alternates between these two states, and is its own inverse. @table @asis @item Line: Set to the last line modified by the command. @item Options: None. @end table @end deftypefn @cindex unmap @deftypefn Command {} {unm[ap][!]} {lhs} Unmap a mapped string. Delete the command mode map definition for @LI{lhs}.

Enter @CO{vi}. The @LI{type}is optional, and can be @QT{-}, @QT{+} or @QT{^}, as in the @CO{ex} @CO{z} command, to specify the position of the specified line in the screen window. (The default is to place the line at the top of the screen window.) A @LI{count}specifies the number of lines that will initially be displayed. (The default is the value of the @OP{window} editor option.) @table @asis @item Line: Unchanged unless @LI{line}is specified, in which case it is set to that line. @item Options: None. @end table @end deftypefn @cindex visual @deftypefn Command {} {vi[sual][!]} {[+cmd] [file]} @CO{Vi} mode only. Edit a new file. Identical to the @QT{edit[!] [+cmd] [file]} command. @sp 1 Capitalizing the first letter of the command, i.e. @CO{Visual}, will edit the file in a new screen. In this case, any modifications to the current file are ignored. @end deftypefn @cindex viusage @deftypefn Command {} {viu[sage]} {[command]} Display usage for a @CO{vi} command. If @LI{command}is specified, a usage statement for that command is displayed. Otherwise, usage statements for all @CO{vi} commands are displayed. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex write @deftypefn Command {[range]} {w[rite][!]} {[>>] [file]} @deftypefnx Command {[range]} {w[rite]} {[!] [file]} @cindex wn @deftypefnx Command {[range]} {wn[!]} {[>>] [file]} @cindex wq @deftypefnx Command {[range]} {wq[!]} {[>>] [file]} Write the file. The specified lines (the entire file, if no range is given) is written to @LI{file}. If @LI{file}is not specified, the current pathname is used. If @LI{file}is specified, and it exists, or if the current pathname was set using the @CO{file} command, and the file already exists, these commands will fail. Appending a @QT{!} character to the command name will override this check and the write will be attempted, regardless. @sp 1 Specifying the optional @QT{>>} string will cause the write to be appended to the file, in which case no tests are made for the file already existing. @sp 1 If the file is preceded by a @QT{!} character, the program named by the shell edit option is invoked with file as its second argument, and the specified lines are passed as standard input to that command. The @QT{!} in this usage must be separated from command name by at least one whitespace character. The special meaning of the @QT{!} may be overridden by escaping it with a backslash @PQ{\e} character. @sp 1 The @CO{wq} version of the write command will exit the editor after writing the file, if there are no further files to edit. Appending a @QT{!} character to the command name or entering two @QQ{quit} commands (i.e. @CO{wq}, @CO{quit}, @CO{xit} or @CO{ZZ}) in a row) will override this check and the editor will exit, ignoring any files that have not yet been edited. @sp 1 The @CO{wn} version of the write command will move to the next file after writing the file, unless the write fails. @table @asis @item Line: Unchanged. @item Options: Affected by the @OP{readonly} and @OP{writeany} options. @end table @end deftypefn @cindex xit @deftypefn Command {[range]} {x[it][!]} {[file]} Write the file if it has been modified. The specified lines are written to @LI{file}, if the file has been modified since the last complete write to any file. If no @LI{range}is specified, the entire file is written. @sp 1 The @CO{xit} command will exit the editor after writing the file, if there are no further files to edit. Appending a @QT{!} character to the command name or entering two @QQ{quit} commands (i.e. @CO{wq}, @CO{quit}, @CO{xit} or @CO{ZZ}) in a row) will override this check and the editor will exit, ignoring any files that have not yet been edited. @table @asis @item Line: Unchanged. @item Options: Affected by the @OP{readonly} and @OP{writeany} options. @end table @end deftypefn @cindex yank @deftypefn Command {[range]} {ya[nk]} {[buffer] [count]} Copy the specified lines to a buffer. If no buffer is specified, the unnamed buffer is used. @table @asis @item Line: Unchanged. @item Options: None. @end table @end deftypefn @cindex z @deftypefn Command {[line]} {z} {[type] [count] [flags]} Adjust the window. If no @LI{type}is specified, then @LI{count}lines following the specified line are displayed. The default @LI{count}is the value of the @OP{window} option. The @LI{type}argument changes the position at which @LI{line}is displayed on the screen by changing the number of lines displayed before and after @LI{line}. The following @LI{type}characters may be used: @table @asis @item - Place the line at the bottom of the screen. @item + Place the line at the top of the screen. @item . Place the line in the middle of the screen. @item ^ Write out count lines starting @LI{count * 2}lines before @LI{line}; the net effect of this is that a @QT{z^} command following a @CO{z} command writes the previous page. @item = Center @LI{line}on the screen with a line of hyphens displayed immediately before and after it. The number of preceding and following lines of text displayed are reduced to account for those lines. @end table @table @asis @item Line: Set to the last line displayed, with the exception of the @QT{=} @LI{type}, where the current line is set to the line specified by the command. @item Options: Affected by the @OP{scroll} option. @end table @end deftypefn nvi-1.81.6/docs/vi.ref/ref.texi0100644000076400001440000000314210720065506015242 0ustar skimousers@comment Copyright (c) 1994 @comment The Regents of the University of California.

This section describes the options, their abbreviations and their default values. In each entry below, the first part of the tag line is the full name of the option, followed by any equivalent abbreviations. (Regardless of the abbreviations, it is only necessary to use the minimum number of characters necessary to distinguish an abbreviation from all other commands for it to be accepted, in @EV{nex,nvi}. Historically, only the full name and the official abbreviations were accepted by @EV{ex,vi}. Using full names in your startup files and environmental variables will probably make them more portable.) The part in square brackets is the default value of the option. Most of the options are boolean, i.e. they are either on or off, and do not have an associated value. Options apply to both @CO{ex} and @CO{vi} modes, unless otherwise specified. With a few exceptions, all options are settable per screen, i.e. the @OP{tags} option can be set differently in each screen. The exceptions are the @OP{columns}, @OP{lines}, @OP{secure} and @OP{term} options. Changing these options modifies the respective information for all screens. For information on modifying the options or to display the options and their current values, see the @QQ{set} command in the section entitled @QB{Ex Commands} . @itemize @bullet @cindex altwerase @IP{altwerase [off]} @CO{Vi} only. Change how @CO{vi} does word erase during text input. When this option is set, text is broken up into three classes: alphabetic, numeric and underscore characters, other nonblank characters, and blank characters. Changing from one class to another marks the end of a word. In addition, the class of the first character erased is ignored (which is exactly what you want when erasing pathname components). @cindex autoindent @IP{autoindent, ai [off]} If this option is set, whenever you create a new line (using the @CO{vi} @CO{A}, @CO{a}, @CO{C}, @CO{c}, @CO{I}, @CO{i}, @CO{O}, @CO{o}, @CO{R}, @CO{r}, @CO{S}, and @CO{s} commands, or the @CO{ex} @CO{append}, @CO{change}, and @CO{insert} commands) the new line is automatically indented to align the cursor with the first nonblank character of the line from which you created it. Lines are indented using tab characters to the extent possible (based on the value of the @OP{tabstop} option) and then using space characters as necessary. For commands inserting text into the middle of a line, any blank characters to the right of the cursor are discarded, and the first nonblank character to the right of the cursor is aligned as described above. @sp 1 The indent characters are themselves somewhat special. If you do not enter more characters on the new line before moving to another line, or entering @LI{}, the indent character will be deleted and the line will be empty. For example, if you enter @LI{}twice in succession, the line created by the first @LI{}will not have any characters in it, regardless of the indentation of the previous or subsequent line. @sp 1 Indent characters also require that you enter additional erase characters to delete them. For example, if you have an indented line, containing only blanks, the first @LI{}character you enter will erase up to end of the indent characters, and the second will erase back to the beginning of the line. (Historically, only the @LI{}key would erase the indent characters. Both the @LI{}key and the usual erase keys work in @CO{nvi}.) In addition, if the cursor is positioned at the end of the indent characters, the keys @QT{0} will erase all of the indent characters for the current line, resetting the indentation level to 0. Similarly, the keys @QT{^} will erase all of the indent characters for the current line, leaving the indentation level for future created lines unaffected. @sp 1 Finally, if the @OP{autoindent} option is set, the @CO{S} and @CO{cc} commands change from the first nonblank of the line to the end of the line, instead of from the beginning of the line to the end of the line. @cindex autoprint @IP{autoprint, ap [off]} @CO{Ex} only. Cause the current line to be automatically displayed after the @CO{ex} commands @CO{<}, @CO{>}, @CO{copy}, @CO{delete}, @CO{join}, @CO{move}, @CO{put}, @CO{t}, @CO{Undo}, and @CO{undo}. This automatic display is suppressed during @CO{global} and @CO{v} commands, and for any command where optional flags are used to explicitly display the line. @cindex autowrite @IP{autowrite, aw [off]} If this option is set, the @CO{vi} @CO{!}, @CO{^^}, @CO{^]} and @CO{} commands, and the @CO{ex} @CO{edit}, @CO{next}, @CO{rewind}, @CO{stop}, @CO{suspend}, @CO{tag}, @CO{tagpop}, and @CO{tagtop} commands automatically write the current file back to the current file name if it has been modified since it was last written. If the write fails, the command fails and goes no further. @sp 1 Appending the optional force flag character @QT{!} to the @CO{ex} commands @CO{next}, @CO{rewind}, @CO{stop}, @CO{suspend}, @CO{tag}, @CO{tagpop}, and @CO{tagtop} stops the automatic write from being attempted. @sp 1 (Historically, the @CO{next} command ignored the optional force flag.) Note, the @CO{ex} commands @CO{edit}, @CO{quit}, @CO{shell}, and @CO{xit} are @emph{not} affected by the @OP{autowrite} option. @sp 1 The @OP{autowrite} option is ignored if the file is considered read-only for any reason. @comment I cannot get a double quote to print between the square brackets @comment to save my life. The ONLY way I've been able to get this to work @comment is with the .tr command. @cindex backup @IP{backup [""]} If this option is set, it specifies a pathname used as a backup file, and, whenever a file is written, the file's current contents are copied to it. The pathname is @QT{#}, @QT{%} and @QT{!} expanded. @sp 1 If the first character of the pathname is @QT{N}, a version number is appended to the pathname (and the @QT{N} character is then discarded). Version numbers are always incremented, and each backup file will have a version number one greater than the highest version number currently found in the directory. @sp 1 Backup files must be regular files, owned by the real user ID of the user running the editor, and not accessible by any other user. @cindex beautify @IP{beautify, bf [off]} If this option is set, all control characters that are not currently being specially interpreted, other than @LI{}, @LI{}, and @LI{}, are discarded from commands read in by @CO{ex} from command files, and from input text entered to @CO{vi} (either into the file or to the colon command line). Text files read by @EV{ex,vi} are @emph{not} affected by the @OP{beautify} option. @cindex cdpath @IP{cdpath [environment variable CDPATH, or current directory]} This option is used to specify a colon separated list of directories which are used as path prefixes for any relative path names used as arguments for the @CO{cd} command. The value of this option defaults to the value of the environmental variable @LI{CDPATH}if it is set, otherwise to the current directory. For compatibility with the POSIX 1003.2 shell, the @CO{cd} command does @emph{not} check the current directory as a path prefix for relative path names unless it is explicitly specified. It may be so specified by entering an empty string or a @QT{.} character into the @LI{CDPATH}variable or the option value. @cindex cedit @IP{cedit [no default]} This option adds the ability to edit the colon command-line history. This option is set to a string. Whenever the first character of that string is entered on the colon command line, you will enter a normal editing window on the collected commands that you've entered on the @CO{vi} colon command-line. You may then modify and/or execute the commands. All normal text editing is available, except that you cannot use @CO{} to switch to an alternate screen. Entering a @CO{} will execute the current line of the screen window as an ex command in the context of the screen from which you created the colon command-line screen, and you will then return to that screen. @sp 1 Because of @CO{vi}'s parsing rules, it can be difficult to set the colon command-line edit character to the @LI{}character. To set it to @LI{}, use @QT{set cedit=}. @sp 1 If the @OP{cedit} edit option is set to the same character as the @OP{filec} edit option, @CO{vi} will perform colon command-line editing if the character is entered as the first character of the line, otherwise, @CO{vi} will perform file name expansion. @cindex columns @IP{columns, co [80]} The number of columns in the screen. Setting this option causes @EV{ex,vi} to set (or reset) the environmental variable @LI{COLUMNS}. See the section entitled @QB{Sizing the Screen} more information. @cindex comment @IP{comment [off]} @CO{Vi} only. If the first non-empty line of the file begins with the string @QT{#}, @QT{/*} or @QT{//}, this option causes @CO{vi} to skip to the end of that shell, C or C++ comment (probably a terribly boring legal notice) before displaying the file. @cindex directory @IP{directory, dir [environment variable TMPDIR, or /tmp]} The directory where temporary files are created. The environmental variable @LI{TMPDIR}is used as the default value if it exists, otherwise @LI{/tmp}is used. @cindex edcompatible @IP{edcompatible, ed [off]} Remember the values of the @QQ{c} and @QQ{g} suffixes to the @CO{substitute} commands, instead of initializing them as unset for each new command. Specifying pattern and replacement strings to the @CO{substitute} command unsets the @QQ{c} and @QQ{g} suffixes as well. @cindex escapetime @IP{escapetime [1]} The 10th's of a second @EV{ex,vi} waits for a subsequent key to complete an @LI{}key mapping. @cindex errorbells @IP{errorbells, eb [off]} @CO{Ex} only. @CO{Ex} error messages are normally presented in inverse video. If that is not possible for the terminal, setting this option causes error messages to be announced by ringing the terminal bell. @cindex exrc @IP{exrc, ex [off]} If this option is turned on in the EXINIT environment variables, or the system or $HOME startup files, the local startup files are read, unless they are the same as the system or $HOME startup files or fail to pass the standard permission checks. See the section entitled @QB{Startup Information} for more information. @cindex extended @IP{extended [off]} This option causes all regular expressions to be treated as POSIX 1003.2 Extended Regular Expressions (which are similar to historic @XR{egrep,1} style expressions). @cindex filec @IP{filec [no default]} This option adds the ability to do shell expansion when entering input on the colon command line. This option is set to a string. Whenever the first character of that string is entered on the colon command line, the delimited string immediately before the cursor is expanded as if it were followed by a @LI{*}character, and file name expansion for the @CO{ex} edit command was done. If no match is found, the screen is flashed and text input resumed. If a single match results, that match replaces the expanded text. In addition, if the single match is for a directory, a @LI{/}character is appended and file completion is repeated. If more than a single match results, any unique prefix shared by the matches replaces the expanded text, the matches are displayed, and text input resumed. @sp 1 Because of @CO{vi}'s parsing rules, it can be difficult to set the path completion character to two command values, @LI{}and @LI{}. To set it to @LI{}, use @QT{set filec=}. To set it to @LI{}, use @QT{set filec=\e}. @sp 1 If the @OP{cedit} edit option is set to the same character as the @OP{filec} edit option, @CO{vi} will perform colon command-line editing if the character is entered as the first character of the line, otherwise, @CO{vi} will perform file name expansion. @cindex flash @IP{flash [on]} This option causes the screen to flash instead of beeping the keyboard, on error, if the terminal has the capability. @cindex hardtabs @IP{hardtabs, ht [8]} This option defines the spacing between hardware tab settings, i.e. the tab expansion done by the operating system and/or the terminal itself. As @EV{nex,nvi} never writes @LI{}characters to the terminal, unlike historic versions of @EV{ex,vi}, this option does not currently have any affect. @cindex iclower @IP{iclower [off]} The @OP{iclower} edit option makes all Regular Expressions case-insensitive, as long as an upper-case letter does not appear in the search string. @cindex ignorecase @IP{ignorecase, ic [off]} This option causes regular expressions, both in @CO{ex} commands and in searches, to be evaluated in a case-insensitive manner. @cindex keytime @IP{keytime [6]} The 10th's of a second @EV{ex,vi} waits for a subsequent key to complete a key mapping. @cindex leftright @IP{leftright [off]} @CO{Vi} only. This option causes the screen to be scrolled left-right to view lines longer than the screen, instead of the traditional @CO{vi} screen interface which folds long lines at the right-hand margin of the terminal. @cindex lines @IP{lines, li [24]} @CO{Vi} only. The number of lines in the screen. Setting this option causes @EV{ex,vi} to set (or reset) the environmental variable @LI{LINES}. See the section entitled @QB{Sizing the Screen} for more information. @cindex lisp @IP{lisp [off]} @CO{Vi} only. This option changes the behavior of the @CO{vi} @CO{(}, @CO{)}, @strong{@{}, @strong{@}}, @CO{[[} and @CO{]]} commands to match the Lisp language. Also, the @OP{autoindent} option's behavior is changed to be appropriate for Lisp. @sp 1 @emph{This option is not yet implemented.} @cindex list @IP{list [off]} This option causes lines to be displayed in an unambiguous fashion. Specifically, tabs are displayed as control characters, i.e. @QT{^I}, and the ends of lines are marked with a @QT{$} character. @cindex lock @IP{lock [on]} This option causes the editor to attempt to get an exclusive lock on any file being edited, read or written. Reading or writing a file that cannot be locked produces a warning message, but no other effect. Editing a file that cannot be locked results in a read only edit session, as if the @OP{readonly} edit option were set. @cindex magic @IP{magic [on]} This option is on by default. Turning the @OP{magic} option off causes all regular expression characters except for @QT{^} and @QT{$}, to be treated as ordinary characters. To re-enable characters individually, when the @OP{magic} option is off, precede them with a backslash @QT{\e} character. See the section entitled @QB{Regular Expressions and Replacement Strings} for more information. @cindex matchtime @IP{matchtime [7]} @CO{Vi} only. The 10th's of a second @CO{vi} pauses on the matching character when the @OP{showmatch} option is set. @cindex mesg @IP{mesg [on]} This option allows other users to contact you using the @XR{talk,1} and @XR{write,1} utilities, while you are editing. @EV{Ex,vi} does not turn message on, i.e. if messages were turned off when the editor was invoked, they will stay turned off. This option only permits you to disallow messages for the edit session. See the @XR{mesg,1} utility for more information. @cindex msgcat @IP{msgcat [./]} This option selects a message catalog to be used to display error and informational messages in a specified language. If the value of this option ends with a '/', it is treated as the name of a directory that contains a message catalog @QT{vi_XXXX}, where @QT{XXXX} is the value of the @LI{LANG}environmental variable, if it's set, or the value of the @LI{LC_MESSAGES}environmental variable if it's not. If neither of those environmental variables are set, or if the option doesn't end in a '/', the option is treated as the full path name of the message catalog to use. @sp 1 If any messages are missing from the catalog, the backup text (English) is used instead. @sp 1 See the distribution file @LI{catalog/README}for additional information on building and installing message catalogs. @cindex modelines @IP{modelines, modeline [off]} If the @OP{modelines} option is set, @EV{ex,vi} has historically scanned the first and last five lines of each file as it is read for editing, looking for any @CO{ex} commands that have been placed in those lines. After the startup information has been processed, and before the user starts editing the file, any commands embedded in the file are executed. @sp 1 Commands were recognized by the letters @QQ{e} or @QQ{v} followed by @QQ{x} or @QQ{i}, at the beginning of a line or following a tab or space character, and followed by a @QQ{:}, an @CO{ex} command, and another @QQ{:}. @sp 1 This option is a security problem of immense proportions, and should not be used under any circumstances. @sp 1 @emph{This option will never be implemented.} @comment I cannot get a double quote to print between the square brackets @comment to save my life. The ONLY way I've been able to get this to work @comment is with the .tr command. @cindex noprint @IP{noprint [""]} Characters that are never handled as printable characters. By default, the C library function @XR{isprint,3} is used to determine if a character is printable or not. This edit option overrides that decision. @cindex number @IP{number, nu [off]} Precede each line displayed with its current line number. @cindex octal @IP{octal [off]} Display unknown characters as octal numbers @PQ{"\e###"}, instead of the default hexadecimal @PQ{"\ex##"}. @cindex open @IP{open [on]} @CO{Ex} only. If this option is not set, the @CO{open} and @CO{visual} commands are disallowed. @cindex optimize @IP{optimize, opt [on]} @CO{Vi} only. Throughput of text is expedited by setting the terminal not to do automatic carriage returns when printing more than one (logical) line of output, greatly speeding output on terminals without addressable cursors when text with leading white space is printed. @sp 1 @emph{This option is not yet implemented.} @cindex paragraphs @IP{paragraphs, para [IPLPPPQPP LIpplpipbp]} @CO{Vi} only. Define additional paragraph boundaries for the @CO{@{} and @strong{@}} commands. The value of this option must be a character string consisting of zero or more character pairs. @sp 1 In the text to be edited, the character string @LI{.}, (where @LI{}is one of the character pairs in the option's value) defines a paragraph boundary. For example, if the option were set to @LI{LaA##}, then all of the following additional paragraph boundaries would be recognized: @sp 1 @example .La .A .## @end example @cindex path @IP{path []} The path option can be used to specify a -separated list of paths, similar to the @LI{PATH}environment variable in the shells. If this option is set, the name of the file to be edited is not an absolute pathname, the first component of the filename is not @QT{.} or @QT{..}, and the file to be edited doesn't exist in the current directory, the elements of the @OP{path} option are sequentially searched for a file of the specified name. If such a file is found, it is edited. @comment I cannot get a double quote to print between the square brackets @comment to save my life. The ONLY way I've been able to get this to work @comment is with the .tr command. @cindex print @IP{print [""]} Characters that are always handled as printable characters. By default, the C library function @XR{isprint,3} is used to determine if a character is printable or not. This edit option overrides that decision. @cindex prompt @IP{prompt [on]} @CO{Ex} only. This option causes @CO{ex} to prompt for command input with a @QT{:} character; when it is not set, no prompt is displayed. @cindex readonly @IP{readonly, ro [off]} This option causes a force flag to be required to attempt to write the file. Setting this option is equivalent to using the @strong{-R} command line option, or executing the @CO{vi} program using the name @CO{view}. @sp 1 The @OP{readonly} edit option is not usually persistent, like other edit options. If the @strong{-R} command line option is set, @CO{vi} is executed as @CO{view}, or the @OP{readonly} edit option is explicitly set, all files edited in the screen will be marked readonly, and the force flag will be required to write them. However, if none of these conditions are true, or the @OP{readonly} edit option is explicitly unset, then the @OP{readonly} edit option will toggle based on the write permissions of the file currently being edited as of when it is loaded into the edit buffer. In other words, the @OP{readonly} edit option will be set if the current file lacks write permissions, and will not be set if the user has write permissions for the file. @cindex recdir @IP{recdir [/var/tmp/vi.recover]} The directory where recovery files are stored. @sp 1 If you change the value of @OP{recdir}, be careful to choose a directory whose contents are not regularly deleted. Bad choices include directories in memory based filesystems, or @LI{/tmp}, on most systems, as their contents are removed when the machine is rebooted. @sp 1 Public directories like @LI{/usr/tmp}and @LI{/var/tmp}are usually safe, although some sites periodically prune old files from them. There is no requirement that you use a public directory, e.g. a sub-directory of your home directory will work fine. @sp 1 Finally, if you change the value of @OP{recdir}, you must modify the recovery script to operate in your chosen recovery area. @sp 1 See the section entitled @QB{Recovery} for further information. @cindex redraw @IP{redraw, re [off]} @CO{Vi} only. The editor simulates (using great amounts of output), an intelligent terminal on a dumb terminal (e.g. during insertions in @CO{vi} the characters to the right of the cursor are refreshed as each input character is typed). @sp 1 @emph{This option is not yet implemented.} @cindex remap @IP{remap [on]} If this option is set, it is possible to define macros in terms of other macros. Otherwise, each key is only remapped up to one time. For example, if @QT{A} is mapped to @QT{B}, and @QT{B} is mapped to @QT{C}, The keystroke @QT{A} will be mapped to @QT{C} if the @OP{remap} option is set, and to @QT{B} if it is not set. @cindex report @IP{report [5]} Set the threshold of the number of lines that need to be changed or yanked before a message will be displayed to the user. For everything but the yank command, the value is the largest value about which the editor is silent, i.e. by default, 6 lines must be deleted before the user is notified. However, if the number of lines yanked is greater than @emph{or equal to} the set value, it is reported to the user. @cindex ruler @IP{ruler [off]} @CO{Vi} only. Display a row/column ruler on the colon command line. @cindex scroll @IP{scroll, scr [(environment variable LINES - 1) / 2]} Set the number of lines scrolled by the @CO{ex} @CO{} and @CO{} commands. @sp 1 Historically, the @CO{ex} @CO{z} command, when specified without a count, used two times the size of the scroll value; the POSIX 1003.2 standard specified the window size, which is a better choice. @cindex searchincr @IP{searchincr [off]} The @OP{searchincr} edit option makes the search commands @CO{/} and @CO{?} incremental, i.e. the screen is updated and the cursor moves to the matching text as the search pattern is entered. If the search pattern is not found, the screen is beeped and the cursor remains on the colon-command line. Erasing characters from the search pattern backs the cursor up to the previous matching text. @cindex sections @IP{sections, sect [NHSHH HUnhsh]} @CO{Vi} only. Define additional section boundaries for the @CO{[[} and @CO{]]} commands. The @OP{sections} option should be set to a character string consisting of zero or more character pairs. In the text to be edited, the character string @LI{.}, (where @LI{}is one of the character pairs in the option's value), defines a section boundary in the same manner that @OP{paragraphs} option boundaries are defined. @cindex secure @IP{secure [off]} The @OP{secure} edit option turns off all access to external programs. This means that the versions of the @CO{read} and @CO{write} commands that filter text through other programs, the @CO{vi} @CO{!} and @CO{} commands, the @CO{ex} @CO{!}, @CO{script}, @CO{shell}, @CO{stop} and @CO{suspend} commands and file name expansion will not be permitted. Once set, the @OP{secure} edit option may not be unset. @cindex shell @IP{shell, sh [environment variable SHELL, or /bin/sh]} Select the shell used by the editor. The specified path is the pathname of the shell invoked by the @CO{vi} @CO{!} shell escape command and by the @CO{ex} @CO{shell} command. This program is also used to resolve any shell meta-characters in @CO{ex} commands. @comment I cannot get a double quote to print between the square brackets @comment to save my life. The ONLY way I've been able to get this to work @comment is with the .tr command. @cindex shellmeta @comment @IP{shellmeta [~@{[*?@$`'"\e]} @item @strong{shellmeta [~@{[*?$`'"\]} The set of characters that @CO{ex} checks for when doing file name expansion. If any of the specified characters are found in the file name arguments to the @CO{ex} commands, the arguments are expanded using the program defined by the @OP{shell} option. The default set of characters is a union of meta characters from the Version 7 and the Berkeley C shell. @cindex shiftwidth @IP{shiftwidth, sw [8]} Set the autoindent and shift command indentation width. This width is used by the @OP{autoindent} option and by the @CO{<}, @CO{>}, and @CO{shift} commands. @cindex showmatch @IP{showmatch, sm [off]} @CO{Vi} only. This option causes @CO{vi}, when a @comment QT ``@code{@}}'' or @QT{)} is entered, to briefly move the cursor the matching @comment QT ``@code{@{}'' or @QT{(}. See the @OP{matchtime} option for more information. @cindex showmode @IP{showmode, smd [off]} @CO{Vi} only. This option causes @CO{vi} to display a string identifying the current editor mode on the colon command line. The string is preceded by an asterisk (``*'') if the file has been modified since it was last completely written, @cindex sidescroll @IP{sidescroll [16]} @CO{Vi} only. Sets the number of columns that are shifted to the left or right, when @CO{vi} is doing left-right scrolling and the left or right margin is crossed. See the @OP{leftright} option for more information. @cindex slowopen @IP{slowopen, slow [off]} This option affects the display algorithm used by @CO{vi}, holding off display updating during input of new text to improve throughput when the terminal in use is slow and unintelligent. @sp 1 @emph{This option is not yet implemented.} @cindex sourceany @IP{sourceany [off]} If this option is turned on, @CO{vi} historically read startup files that were owned by someone other than the editor user. See the section entitled @QB{Startup Information} for more information. This option is a security problem of immense proportions, and should not be used under any circumstances. @sp 1 @emph{This option will never be implemented.} @cindex tabstop @IP{tabstop, ts [8]} This option sets tab widths for the editor display. @cindex taglength @IP{taglength, tl [0]} This option sets the maximum number of characters that are considered significant in a tag name. Setting the value to 0 makes all of the characters in the tag name significant. @cindex tags @IP{tags, tag [tags /var/db/libc.tags /sys/kern/tags]} Sets the list of tags files, in search order, which are used when the editor searches for a tag. @cindex term @IP{term, ttytype, tty [environment variable TERM]} Set the terminal type. Setting this option causes @EV{ex,vi} to set (or reset) the environmental variable @LI{TERM}. @cindex terse @IP{terse [off]} This option has historically made editor messages less verbose. It has no effect in this implementation. See the @OP{verbose} option for more information. @cindex tildeop @IP{tildeop [off]} Modify the @CO{~} command to take an associated motion. @cindex timeout @IP{timeout, to [on]} If this option is set, @EV{ex,vi} waits for a specific period for a subsequent key to complete a key mapping (see the @OP{keytime} option). If the option is not set, the editor waits until enough keys are entered to resolve the ambiguity, regardless of how long it takes. @cindex ttywerase @IP{ttywerase [off]} @CO{Vi} only. This option changes how @CO{vi} does word erase during text input. If this option is set, text is broken up into two classes, blank characters and nonblank characters. Changing from one class to another marks the end of a word. @cindex verbose @IP{verbose [off]} @CO{Vi} only. @CO{Vi} historically bells the terminal for many obvious mistakes, e.g. trying to move past the left-hand margin, or past the end of the file. If this option is set, an error message is displayed for all errors. @cindex w300 @IP{w300 [no default]} @CO{Vi} only. Set the window size if the baud rate is less than 1200 baud. See the @OP{window} option for more information. @cindex w1200 @IP{w1200 [no default]} @CO{Vi} only. Set the window size if the baud rate is equal to 1200 baud. See the @OP{window} option for more information. @cindex w9600 @IP{w9600 [no default]} @CO{Vi} only. Set the window size if the baud rate is greater than 1200 baud. See the @OP{window} option for more information. @cindex warn @IP{warn [on]} @CO{Ex} only. This option causes a warning message to the terminal if the file has been modified, since it was last written, before a @CO{!} command. @cindex window @IP{window, w, wi [environment variable LINES - 1]} This option determines the default number of lines in a screenful, as displayed by the @CO{z} command. It also determines the number of lines scrolled by the @CO{vi} commands @CO{} and @CO{}, and the default number of lines scrolled by the @CO{vi} commands @CO{} and @CO{}. The value of window can be unrelated to the real screen size, although it starts out as the number of lines on the screen. See the section entitled @QB{Sizing the Screen} for more information. Setting the value of the @OP{window} option is the same as using the @strong{-w} command line option. @sp 1 If the value of the @OP{window} option (as set by the @OP{window}, @OP{w300}, @OP{w1200} or @OP{w9600} options) is smaller than the actual size of the screen, large screen movements will result in displaying only that smaller number of lines on the screen. (Further movements in that same area will result in the screen being filled.) This can provide a performance improvement when viewing different places in one or more files over a slow link. @sp 1 Resetting the window size does not reset the default number of lines scrolled by the @CO{} and @CO{} commands. @cindex windowname @IP{windowname [off]} @CO{Vi} changes the name of the editor's icon/window to the current file name when it's possible and not destructive, i.e., when the editor can restore it to its original value on exit or when the icon/window will be discarded as the editor exits. If the @OP{windowname} edit option is set, @CO{vi} will change the icon/window name even when it's destructive and the icon/window name will remain after the editor exits. (This is the case for @XR{xterm,1}). @cindex wraplen @IP{wraplen, wl [0]} This option is identical to the @OP{wrapmargin} option, with the exception that it specifies the number of columns from the @emph{left} margin before the line splits, not the right margin. @sp 1 If both @OP{wraplen} and @OP{wrapmargin} are set, the @OP{wrapmargin} value is used. @cindex wrapmargin @IP{wrapmargin, wm [0]} @CO{Vi} only. If the value of the @OP{wrapmargin} option is non-zero, @CO{vi} will split lines so that they end at least that number of columns before the right-hand margin of the screen. (Note, the value of @OP{wrapmargin} is @emph{not} a text length. In a screen that is 80 columns wide, the command @QT{:set wrapmargin=8} attempts to keep the lines less than or equal to 72 columns wide.) @sp 1 Lines are split at the previous whitespace character closest to the number. Any trailing whitespace characters before that character are deleted. If the line is split because of an inserted @LI{}or @LI{}character, and you then enter another @LI{}character, it is discarded. @sp 1 If wrapmargin is set to 0, or if there is no blank character upon which to split the line, the line is not broken. @sp 1 If both @OP{wraplen} and @OP{wrapmargin} are set, the @OP{wrapmargin} value is used. @cindex wrapscan @IP{wrapscan, ws [on]} This option causes searches to wrap around the end or the beginning of the file, and back to the starting point. Otherwise, the end or beginning of the file terminates the search. @cindex writeany @IP{writeany, wa [off]} If this option is set, file-overwriting checks that would usually be made before the @CO{write} and @CO{xit} commands, or before an automatic write (see the @OP{autowrite} option), are not made. This allows a write to any file, provided the file permissions allow it. @end itemize nvi-1.81.6/docs/vi.ref/spell.ok0100644000076400001440000000531610720065506015252 0ustar skimousersABC Amir Autoindent Autoprint BRE's Bostic Bourne CDPATH CSCOPE Cscope DIRS DOUBLEQUOTE Dq Ds ERE's EXINIT Englar Ev FF Fa Fg FindScreen Fl Foregrounding HUnhsh IPLPPPQPP Kirkendall Korn LC LIpplpipbp LaA Li Lowercase MINUSSIGN Makefiles Mayoff NEX NEXINIT NHSHH NVI Neville Nex Nvi OS POSIX Perl PostScript QQ RE's README RECDIR Reference''USD:13 SENDMAIL SIGHUP SIGWINCH SQUOTE Se Std Std1003.2 Sven Sy TANDARDS TIOCGWINSZ TMPDIR TOC Tagnext Tagprev Tcl Tk Todo USD USD.doc USD:13 UUNET Unmap VI Verdoolaege Vi Vx Whitespace XOFF XON XOptions XXCOLUMNS XXXX XXXXXX XXb ZZ ab abbrev abc ags ai al altwerase ap api ar arg args att autoindent autoprint autowrite aw backgrounded backgrounding bbrev berkeley bf bg bigword bigwords bostic bp brev bsd bugs.current c2w carat cd cdpath cdy cedit changelog chd chdir cmd co count1 count2 creens cs cs.berkeley.edu cscope ctags cw db dbopen dd def di dir dit docs eE eFlRsv eFlRv eL eU ead eb edcompatible edu ee egrep elete elp elvis email enum eof errorbells esc escapetime eset eu ex.cmd.roff exrc ext exu exusage fcntl fg fi filec filesystem filesystems foo foregrounded foregrounding ftp.cs.berkeley.edu ftp.uu.net gdb gdb.script getpwent gs gzip'd halfbyte hange hangup hardtabs ht html http ic iclower ifdef ignorecase ile ind initially ious ir iscntrl isprint ist ize keystroke keystrokes keytime leftright lhs li lib libc libc.tags lineNum lineNumber lobal lowercase lp luR matchtime mber mesg meta mk mkexrc modeful modeline modelines ms msgcat ndo nex nexrc nk nomagic nonblank nonoverlapping nooption noprint nsert nul nvi nvi.tar.Z nvi.tar.z nz oin onnections op ove para pathname pathnames pe perl perld ppend prev pu py rc rc.local readonly rec recdir recfile recover.XXXX recover.XXXXXX recover.c recover.script redist redistributable reimplementations remapmax remapped repl res rew rhs rint ript rk rl ro roff rsion sc sccs scr screeen screenId se searchincr sendmail set.opt.roff settable setuid sh shareware shellmeta shiftwidth showmatch showmode sidescroll slowopen sm smd sourceany sp spell.ok ssg st su sual svi sw ta tabstop taglength tagn tagnext tagp tagpop tagprev tagstring tagt tagtop tc tcl tclproc terminfo th th's tildeop tl tmp toolchest tpath tr ts ttytype ttywerase uR ubstitute ucb uffers uit una unabbrev unescaped unm unmap unsets uppercase urce usr uunet v var ve vi vi.0.ps vi.0.txt vi.1 vi.XXXX vi.XXXXXX vi.cmd.roff vi.exrc vi.recover viAppendLine viDelLine viEndScreen viFindScreen viGetCursor viGetLine viGetMark viGetOpt viInsertLine viLastLine viMapKey viMsg viNewScreen viSetCursor viSetLine viSetMark viSetOpt viSwitchScreen viUnmMapKey vibackup virecovery viu viusage wa whitespace wi windowname wl wm wn wq wraplen wrapmargin wrapscan writeany ws www xaw xit xterm ya yy nvi-1.81.6/docs/vi.ref/vi.cmd.texi0100644000076400001440000022760110720065506015656 0ustar skimousers@comment Copyright (c) 1994 @comment The Regents of the University of California.

The bottom line of the screen is used to enter @CO{exp} commands, and for @CO{vi} error and informational messages. If no other information is being displayed, the default display can show the current cursor row and cursor column, an indication of whether the file has been modified, and the current mode of the editor. See the @OP{ruler} and @OP{showmode} options for more information. Empty lines do not have any special representation on the screen, but lines on the screen that would logically come after the end of the file are displayed as a single tilde @PQ{~} character. To differentiate between empty lines and lines consisting of only whitespace characters, use the @OP{list} option. Historically, implementations of @CO{vi} have also displayed some lines as single asterisk @PQ{@@} characters. These were lines that were not correctly displayed, i.e. lines on the screen that did not correspond to lines in the file, or lines that did not fit on the current screen. @CO{Nvi} never displays lines in this fashion. @CO{Vi} is a modeful editor, i.e. it has two modes, @QQ{command} mode and @QQ{text input} mode. When @CO{vi} first starts, it is in command mode. There are several commands that change @CO{vi} into text input mode. The @LI{}character is used to resolve the text input into the file, and exit back into command mode. In @CO{vi} command mode, the cursor is always positioned on the last column of characters which take up more than one column on the screen. In @CO{vi} text insert mode, the cursor is positioned on the first column of characters which take up more than one column on the screen. When positioning the cursor to a new line and column, the type of movement is defined by the distance to the new cursor position. If the new position is close, the screen is scrolled to the new location. If the new position is far away, the screen is repainted so that the new position is on the screen. If the screen is scrolled, it is moved a minimal amount, and the cursor line will usually appear at the top or bottom of the screen. If the screen is repainted, the cursor line will appear in the center of the screen, unless the cursor is sufficiently close to the beginning or end of the file that this isn't possible. If the @OP{leftright} option is set, the screen may be scrolled or repainted in a horizontal direction as well as in a vertical one. A major difference between the historical @CO{vi} presentation and @CO{nvi} is in the scrolling and screen oriented position commands, @CO{}, @CO{}, @CO{}, @CO{}, @CO{}, @CO{}, @CO{H}, @CO{L} and @CO{M}. In historical implementations of @CO{vi}, these commands acted on physical (as opposed to logical, or screen) lines. For lines that were sufficiently long in relation to the size of the screen, this meant that single line scroll commands might repaint the entire screen, scrolling or screen positioning commands might not change the screen or move the cursor at all, and some lines simply could not be displayed, even though @CO{vi} would edit the file that contained them. In @CO{nvi}, these commands act on logical, i.e. screen lines. You are unlikely to notice any difference unless you are editing files with lines significantly longer than a screen width. @CO{Vi} keeps track of the currently @QQ{most attractive} cursor position. Each command description (for commands that alter the current cursor position), specifies if the cursor is set to a specific location in the line, or if it is moved to the @QQ{most attractive cursor position}. The latter means that the cursor is moved to the cursor position that is horizontally as close as possible to the current cursor position. If the current line is shorter than the cursor position @CO{vi} would select, the cursor is positioned on the last character in the line. (If the line is empty, the cursor is positioned on the first column of the line.) If a command moves the cursor to the most attractive position, it does not alter the current cursor position, and a subsequent movement will again attempt to move the cursor to that position. Therefore, although a movement to a line shorter than the currently most attractive position will cause the cursor to move to the end of that line, a subsequent movement to a longer line will cause the cursor to move back to the most attractive position. In addition, the @CO{$} command makes the end of each line the most attractive cursor position rather than a specific column. Each @CO{vi} command described below notes where the cursor ends up after it is executed. This position is described in terms of characters on the line, i.e. @QQ{the previous character}, or, @QQ{the last character in the line}. This is to avoid needing to continually refer to on what part of the character the cursor rests. The following words have special meaning for @CO{vi} commands. @itemize @bullet @cindex "previous context" @IP{previous context} The position of the cursor before the command which caused the last absolute movement was executed. Each @CO{vi} command described in the next section that is considered an absolute movement is so noted. In addition, specifying @emph{any} address to an @CO{ex} command is considered an absolute movement. @cindex "motion" @IP{motion} A second @CO{vi} command can be used as an optional trailing argument to the @CO{vi} @CO{<}, @CO{>}, @CO{!}, @CO{c}, @CO{d}, @CO{y}, and (depending on the @OP{tildeop} option) @CO{~} commands. This command indicates the end of the region of text that's affected by the command. The motion command may be either the command character repeated (in which case it means the current line) or a cursor movement command. In the latter case, the region affected by the command is from the starting or stopping cursor position which comes first in the file, to immediately before the starting or stopping cursor position which comes later in the file. Commands that operate on lines instead of using beginning and ending cursor positions operate on all of the lines that are wholly or partially in the region. In addition, some other commands become line oriented depending on where in the text they are used. The command descriptions below note these special cases. @sp 1 The following commands may all be used as motion components for @CO{vi} commands: @sp 1 @multitable {@CO{}} {@CO{'}} {@CO{}} {@CO{}} @item @CO{} @tab @CO{} @tab @CO{} @tab @CO{} @item @CO{} @tab @CO{} @tab @CO{} @tab @CO{$} @item @CO{%} @tab @CO{'} @tab @CO{(} @tab @CO{)} @item @CO{+} @tab @CO{,} @tab @CO{-} @tab @CO{/} @item @CO{0} @tab @CO{;} @tab @CO{?} @tab @CO{B} @item @CO{E} @tab @CO{F} @tab @CO{G} @tab @CO{H} @item @CO{L} @tab @CO{M} @tab @CO{N} @tab @CO{T} @item @CO{W} @tab @CO{[[} @tab @CO{]]} @tab @CO{^} @item @CO{_} @tab @CO{`} @tab @CO{b} @tab @CO{e} @item @CO{f} @tab @CO{h} @tab @CO{j} @tab @CO{k} @item @CO{l} @tab @CO{n} @tab @CO{t} @tab @CO{w} @item @strong{@{} @tab @CO{|} @tab @strong{@}} @end multitable @sp 1 The optional count prefix available for some of the @CO{vi} commands that take motion commands, or the count prefix available for the @CO{vi} commands that are used as motion components, may be included and is @emph{always} considered part of the motion argument. For example, the commands @QT{c2w} and @QT{2cw} are equivalent, and the region affected by the @CO{c} command is two words of text. In addition, if the optional count prefix is specified for both the @CO{vi} command and its motion component, the effect is multiplicative and is considered part of the motion argument. For example, the commands @QT{4cw} and @QT{2c2w} are equivalent, and the region affected by the @CO{c} command is four words of text. @cindex "count" @IP{count} A positive number used as an optional argument to most commands, either to give a size or a position (for display or movement commands), or as a repeat count (for commands that modify text). The count argument is always optional and defaults to 1 unless otherwise noted in the command description. @sp 1 When a @CO{vi} command synopsis shows both a @LI{[buffer]}and @LI{[count]}, they may be presented in any order. @cindex word @IP{word} Generally, in languages where it is applicable, @CO{vi} recognizes two kinds of words. First, a sequence of letters, digits and underscores, delimited at both ends by: characters other than letters, digits, or underscores, the beginning or end of a line, and the beginning or end of the file. Second, a sequence of characters other than letters, digits, underscores, or whitespace characters, delimited at both ends by: a letter, digit, underscore, or whitespace character, the beginning or end of a line, and the beginning or end of the file. For example, the characters @QT{ !@@#abc$%^ } contain three words: @QT{!@@#}, @QT{abc} and @QT{$%^}. @sp 1 Groups of empty lines (or lines containing only whitespace characters) are treated as a single word. @cindex "bigword" @IP{bigword} A set of non-whitespace characters preceded and followed by whitespace characters or the beginning or end of the file or line. For example, the characters @QT{ !@@#abc$%^ } contain one bigword: @QT{!@@#abc$%^}. @sp 1 Groups of empty lines (or lines containing only whitespace characters) are treated as a single bigword. @cindex "paragraph" @IP{paragraph} An area of text that begins with either the beginning of a file, an empty line, or a section boundary, and continues until either an empty line, section boundary, or the end of the file. @sp 1 Groups of empty lines (or lines containing only whitespace characters) are treated as a single paragraph. @sp 1 Additional paragraph boundaries can be defined using the @OP{paragraphs} option. @cindex "section" @IP{section} An area of text that starts with the beginning of the file or a line whose first character is an open brace @comment PQ ``@code{@{}'' and continues until the next section or the end of the file. @sp 1 Additional section boundaries can be defined using the @OP{sections} option. @cindex "sentence" @IP{sentence} An area of text that begins with either the beginning of the file or the first nonblank character following the previous sentence, paragraph, or section boundary and continues until the end of the file or a period @PQ{.} exclamation point @PQ{!} or question mark @PQ{?} character, followed by either an end-of-line or two whitespace characters. Any number of closing parentheses @PQ{)}, brackets @PQ{]}, double-quote @PQ{"} or single quote @PQ{'} characters can appear between the period, exclamation point, or question mark and the whitespace characters or end-of-line. @sp 1 Groups of empty lines (or lines containing only whitespace characters) are treated as a single sentence. @chapter Vi Commands @end itemize The following section describes the commands available in the command mode of the @CO{vi} editor. In each entry below, the tag line is a usage synopsis for the command character. In addition, the final line and column the cursor rests upon, and any options which affect the command are noted. @cindex @deftypefn Command {[count]} {} Search forward @LI{count}times for the current word.

If no subsequent word exists on the current line, move to the first character of the first word on the first following line that contains a word. @sp 1 The @CO{w} command may be used as the motion component of other @CO{vi} commands, in which case any text copied into a buffer is character oriented. @table @asis @item Line: Set to the line containing the word selected. @item Column: Set to the first character of the word selected. @item Options: None. @end table @end deftypefn @cindex x @deftypefn Command {[buffer] [count]} {x} Delete @LI{count}characters.

If @LI{count2}is not specified, it defaults to the current window size. @sp 1 The following @LI{type}characters may be used: @table @asis @item + If @LI{count1}is specified, place the line @LI{count1}at the top of the screen. Otherwise, display the screen after the current screen, similarly to the @CO{} command. @item Place the line @LI{count1}at the top of the screen. @item . Place the line @LI{count1}in the center of the screen. @item - Place the line @LI{count1}at the bottom of the screen. @item ^ If @LI{count1}is specified, place the line that is at the top of the screen when @LI{count1}is at the bottom of the screen, at the bottom of the screen, i.e. display the screen before the screen before @LI{count1}. Otherwise, display the screen before the current screen, similarly to the @CO{} command. @end table @table @asis @item Line: Set to @LI{count1}unless @LI{count1}is not specified and the @LI{type}character was either @QT{^} or @QT{+}, in which case it is set to the line before the first line on the previous screen or the line after the last line on the previous screen, respectively. @item Column: Set to the first nonblank character in the line. @item Options: None. @end table @end deftypefn @cindex @{ @deftypefn Command {[count]} @{ Move backward @LI{count}paragraphs. @sp 1 The @strong{@{} command is an absolute movement.

Many of the potentially long-running @CO{vi} commands may be interrupted using the terminal interrupt character.

Historically, @CO{vi} implementations only permitted the characters inserted on the current line to be erased. In addition, only the @LI{}erase character and the @QT{0} and @QT{^} erase strings could erase autoindent characters. (Autoindent characters include both the characters inserted automatically at the beginning of an input line as well as characters inserted using the @LI{}command.) This implementation permits erasure to continue past the beginning of the current line, and back to where text input mode was entered. In addition, autoindent characters may be erased using the standard erase characters. For the line and word erase characters, reaching the autoindent characters forms a @QQ{soft} boundary, denoting the end of the current word or line erase. Repeating the word or line erase key will erase the autoindent characters. Historically, @CO{vi} always used @LI{}and @LI{}as character and word erase characters, respectively, regardless of the current terminal settings. This implementation accepts, in addition to these two characters, the current terminal characters for those operations. @cindex @deftypefn Input {} {} If the first character of the input is a @LI{}, the previous input is replayed, as if just entered. @end deftypefn @cindex @deftypefn Input {} {} If the previous character on the line was an autoindent character, erase characters to move the cursor back to the column immediately after the previous (1-based) column which is a multiple of the @OP{shiftwidth} edit option. This may result in any number of @LI{}and @LI{}characters preceding the cursor being changed. @sp 1 Otherwise, if the @OP{autoindent} option is set and the user is entering the first character in the line, @LI{}is ignored. Otherwise, a literal @LI{}character is entered. @end deftypefn @cindex ^ @deftypefn Input {} {^} If the previous character on the line was an autoindent character, erase all of the autoindent characters on the line. In addition, the autoindent level is reset to 0. @end deftypefn @cindex 0 @deftypefn Input {} {0} If the previous character on the line was an autoindent character, erase all of the autoindent characters on the line. The autoindent level is not altered. @end deftypefn @cindex @deftypefn Input {} {} Insert sufficient @LI{}and @LI{}characters to move the cursor forward to the column immediately after the next (1-based) column which is a multiple of the @OP{shiftwidth} edit option. This may result in any number of @LI{}and @LI{}characters preceding the cursor being changed. @sp 1 Historically, @CO{vi} did not permit the @LI{}command to be used unless the cursor was at the first column of a new line or it was preceded only by autoindent characters. @CO{Nvi} permits it to be used at any time during insert mode. @end deftypefn @cindex @deftypefn Input {} {} @cindex @deftypefnx Input {} {} Erase the last character. @end deftypefn @cindex "" @deftypefn Input {} {} Quote the next character. The next character will not be mapped (see the @CO{map} command for more information) or interpreted specially. A carat @PQ{^} character will be displayed immediately as a placeholder, but will be replaced by the next character. @end deftypefn @cindex @deftypefn Input {} {} If on the colon command line, and the @OP{filec} edit option is set, behave as described for that option. Otherwise, if on the colon command line, execute the command. Otherwise, if not on the colon command line, resolve all text input into the file, and return to command mode. @end deftypefn @cindex "" @deftypefn Input {} {} Erase the current line. @end deftypefn @cindex "" @deftypefn Input {} {} @cindex "" @deftypefnx Input {} {} Erase the last word. The definition of word is dependent on the @OP{altwerase} and @OP{ttywerase} options. @end deftypefn @cindex "" @deftypefn Input {} {[0-9A-Fa-f]+} Insert a character with the specified hexadecimal value into the text. The value is delimited by any non-hexadecimal character or the input of the maximum number of characters that can be translated into a single character value. @end deftypefn @cindex @deftypefn Input {} {} Interrupt text input mode, returning to command mode. If the @LI{}character is used to interrupt inserting text into the file, it is as if the @LI{}character was used; all text input up to the interruption is resolved into the file. @end deftypefn nvi-1.81.6/docs/vi.ref/vi.texi0100644000076400001440000013334210720065506015112 0ustar skimousers\input texinfo @setfilename vi.ref.info @setchapternewpage off @syncodeindex fn cp @comment Copyright (c) 1994 @comment The Regents of the University of California.

Peter Kessler helped bring sanity to version 2's command layout. Bill Joy wrote versions 1 and 2.0 through 2.7, and created the framework that users see in the present editor. Mark Horton added macros and other features and made @EV{ex,vi} work on a large number of terminals and Unix systems. @CO{Nvi} is originally derived from software contributed to the University of California, Berkeley by Steve Kirkendall, the author of the @CO{vi} clone @CO{elvis}. IEEE Standard Portable Operating System Interface for Computer Environments (POSIX) 1003.2 style Regular Expression support was done by Henry Spencer. The curses library was originally done by Ken Arnold. Scrolling and reworking for @CO{nvi} was done by Elan Amir. George Neville-Neil added the Tcl interpreter, and Sven Verdoolaege added the Perl interpreter. Rob Mayoff added Cscope support.

This reference manual is the one provided with the @EV{nex,nvi} versions of the @EV{ex,vi} text editors. @EV{Nex,nvi} are intended as bug-for-bug compatible replacements for the original Fourth Berkeley Software Distribution (4BSD) @EV{ex,vi} programs. This reference manual is accompanied by a traditional-style manual page. That manual page describes the functionality found in @EV{ex,vi} in far less detail than the description here. In addition, it describes the system interface to @EV{ex,vi}, e.g. command line options, session recovery, signals, environmental variables, and similar things. This reference is intended for users already familiar with @EV{ex,vi}. Anyone else should almost certainly read a good tutorial on the editor first. If you are in an unfamiliar environment, and you absolutely have to get work done immediately, see the section entitled @QB{Fast Startup} in the manual page. It is probably enough to get you started. There are a few features in @EV{nex,nvi} that are not found in historic versions of @EV{ex,vi}. Some of the more interesting of those features are briefly described in the next section, entitled @QB{Additional Features} . For the rest of this document, @EV{nex,nvi} is used only when it is necessary to distinguish it from the historic implementations of @EV{ex,vi}. Future versions of this software will be periodically made available by anonymous ftp, and can be retrieved from @LI{ftp.cs.berkeley.edu}, in the directory @LI{ucb/4bsd}. @chapter Additional Features in Nex/Nvi There are a few features in @EV{nex,nvi} that are not found in historic versions of @EV{ex,vi}. Some of the more interesting of these are as follows: @itemize @bullet @IP{8-bit clean data, large lines, files} @EV{Nex,nvi} will edit any format file. Line lengths are limited by available memory, and file sizes are limited by available disk space. The @CO{vi} text input mode command @CO{} can insert any possible character value into the text. @IP{Background and foreground screens} The @CO{bg} command backgrounds the current screen, and the @CO{fg} command foregrounds backgrounded screens. The @CO{display} command can be used to list the background screens. @IP{Command Editing} You can enter a normal editing window on the collected commands that you've entered on the @CO{vi} colon command-line, and then modify and/or execute the commands. See the @OP{cedit} edit option for more information. @IP{Displays} The @CO{display} command can be used to display the current buffers, the backgrounded screens, and the tags stack. @IP{Extended Regular Expressions} The @CO{extended} option causes Regular Expressions to be interpreted as as Extended Regular Expressions, (i.e.@: @command{egrep}(1) style Regular Expressions). @IP{File Name Completion} It is possible to do file name completion and file name displays when entering commands on the @CO{vi} colon command-line. See the @OP{filec} option for more information. @IP{Infinite undo} Changes made during an edit session may be rolled backward and forward. A @CO{.} command immediately after a @CO{u} command continues either forward or backward depending on whether the @CO{u} command was an undo or a redo. @IP{Left-right scrolling} The @CO{leftright} option causes @CO{nvi} to do left-right screen scrolling, instead of the traditional @CO{vi} line wrapping. @IP{Message Catalogs} It is possible to display informational and error messages in different languages by providing a catalog of messages. See the @OP{msgcat} option and the file @LI{catalog/README}for more information. @IP{Incrementing numbers} The @CO{#} command increments or decrements the number referenced by the cursor. @IP{Previous file} The @CO{previous} command edits the previous file from the argument list. @IP{Scripting languages} The @CO{:pe[rl] cmd}, @CO{:perld[o] cmd} and @CO{:tc[l] cmd} commands execute Perl and Tcl/Tk commands, respectively, on lines from the edit buffer. See the @QB{Scripting Languages} section and the specific commands for more information. @comment @IP{Shell screens} @comment The @comment @CO{:sc[ript] [file ...]} @comment command runs a shell in the screen. @comment Editing is unchanged, with the exception that a \fC\fP @comment enters the current line (stripped of any prompt) as input to the @comment shell. @IP{Split screens} The @CO{Edit} , @CO{Ex} , @CO{Next} , @CO{Previous} , @CO{Tag} and @CO{Visual} (in @CO{vi} mode) commands divide the screen into multiple editing regions and then perform their normal function in a new screen area. The @CO{} command rotates between the foreground screens. The @CO{resize} command can be used to grow or shrink a particular screen. @IP{Tag stacks} Tags are now maintained in a stack. The @CO{} command returns to the previous tag location. The @CO{tagpop} command returns to the most recent tag location by default, or, optionally to a specific tag number in the tag stack, or the most recent tag from a specified file. The @CO{display} command can be used to list the tags stack. The @CO{tagtop} command returns to the top of the tag stack. @IP{Usage information} The @CO{exusage} and @CO{viusage} commands provide usage information for all of the @CO{ex} and @CO{vi} commands by default, or, optionally, for a specific command or key. @IP{Word search} The @CO{} command searches for the word referenced by the cursor. @end itemize @chapter Startup Information @EV{Ex,vi} interprets one of two possible environmental variables and reads up to three of five possible files during startup. The variables and files are expected to contain @CO{ex} commands, not @CO{vi} commands. In addition, they are interpreted @emph{before} the file to be edited is read, and therefore many @CO{ex} commands may not be used. Generally, any command that requires output to the screen or that needs a file upon which to operate, will cause an error if included in a startup file or environmental variable. Because the @CO{ex} command set supported by @EV{nex,nvi} is a superset of the command set supported by historical implementations of @CO{ex} , @EV{nex,nvi} can use the startup files created for the historical implementations, but the converse may not be true. If the @strong{-s} (the historic - option) is specified, or if standard input is redirected from a file, all environmental variables and startup files are ignored. Otherwise, startup files and environmental variables are handled in the following order: @enumerate @item The file @LI{/etc/vi.exrc}is read, as long as it is owned by root or the effective user ID of the user. @item The environmental variable @LI{NEXINIT}(or the variable @LI{EXINIT}, if @LI{NEXINIT}is not set) is interpreted. @item If neither @LI{NEXINIT}or @LI{EXINIT}was set, and the @LI{HOME}environmental variable is set, the file @LI{$HOME/.nexrc}(or the file @LI{$HOME/.exrc}, if @LI{$HOME/.nexrc}does not exist) is read, as long as the effective user ID of the user is root or is the same as the owner of the file. @sp 1 When the $HOME directory is being used for both @EV{nex,nvi} and an historic implementation of @EV{ex,vi}, a possible solution is to put @EV{nex,nvi} specific commands in the @LI{.nexrc}file, along with a @CO{:source $HOME/.exrc} command to read in the commands common to both implementations. @item If the @OP{exrc} option was turned on by one of the previous startup information sources, the file @LI{.nexrc}(or the file @LI{.exrc}, if @LI{.nexrc}does not exist) is read, as long as the effective user ID of the user is the same as the owner of the file. @end enumerate No startup file is read if it is writable by anyone other than its owner. It is not an error for any of the startup environmental variables or files not to exist. Once all environmental variables are interpreted, and all startup files are read, the first file to be edited is read in (or a temporary file is created). Then, any commands specified using the @strong{-c} option are executed, in the context of that file. @chapter Recovery There is no recovery program for @EV{nex,nvi}, nor does @EV{nex,nvi} run setuid. Recovery files are created readable and writable by the owner only. Users may recover any file which they can read, and the superuser may recover any edit session. Edit sessions are backed by files in the directory named by the @OP{recdir} option (the directory @LI{/var/tmp/vi.recover}by default), and are named @QC{vi.XXXXXX}, where @QC{XXXXXX} is a number related to the process ID. When a file is first modified, a second recovery file containing an email message for the user is created, and is named @QC{recover.XXXXXX}, where, again, @QC{XXXXXX} is associated with the process ID. Both files are removed at the end of a normal edit session, but will remain if the edit session is abnormally terminated or the user runs the @CO{ex} @CO{preserve} command. The @OP{recdir} option may be set in either the user's or system's startup information, changing the recovery directory. (Note, however, that if a memory based file system is used as the backup directory, each system reboot will delete all of the recovery files! The same caution applies to directories such as @LI{/tmp}which are cleared of their contents by a system reboot, or @LI{/usr/tmp}which is periodically cleared of old files on many systems.) The recovery directory should be owned by root, or at least by a pseudo-user. In addition, if directory @QQ{sticky-bit} semantics are available, the directory should have the sticky-bit set so that files may only be removed by their owners. The recovery directory must be read, write, and executable by any user, i.e.@: mode 1777. If the recovery directory does not exist, @EV{ex,vi} will attempt to create it. This can result in the recovery directory being owned by a normal user, which means that that user will be able to remove other user's recovery and backup files. This is annoying, but is not a security issue as the user cannot otherwise access or modify the files. The recovery file has all of the necessary information in it to enable the user to recover the edit session. In addition, it has all of the necessary email headers for @XR{sendmail,8}. When the system is rebooted, all of the files in @LI{/var/tmp/vi.recover}named @QC{recover.XXXXXX} should be sent to their owners, by email, using the @strong{-t} option of @CO{sendmail} (or a similar mechanism in other mailers). If @EV{ex,vi} receives a hangup (SIGHUP) signal, or the user executes the @CO{ex} @CO{preserve} command, @EV{ex,vi} will automatically email the recovery information to the user. If your system does not have the @CO{sendmail} utility (or a mailer program which supports its interface) the source file @LI{nvi/common/recover.c}will have to be modified to use your local mail delivery programs. Note, if @EV{nex,nvi} is changed to use another mailer, it is important to remember that the owner of the file given to the mailer is the @EV{nex,nvi} user, so nothing in the file should be trusted as it may have been modified in an effort to compromise the system. Finally, the owner execute bit is set on backup files when they are created, and unset when they are first modified, e.g. backup files that have no associated email recovery file will have this bit set. (There is also a small window where empty files can be created and not yet have this bit set. This is due to the method in which the files are created.) Such files should be deleted when the system reboots. A simple way to do this cleanup is to run the Bourne shell script @CO{recover} , from your @LI{/etc/rc.local}(or other system startup) file. The script should work with the historic Bourne shell, a POSIX 1003.2 shell or the Korn shell. The @CO{recover} script is installed as part of the @EV{nex,nvi} installation process. Consult the manual page for details on recovering preserved or aborted editing sessions. @chapter Sizing the Screen The size of the screen can be set in a number of ways. @EV{Ex,vi} takes the following steps until values are obtained for both the number of rows and number of columns in the screen. @enumerate @item If the environmental variable @LI{LINES}exists, it is used to specify the number of rows in the screen. @item If the environmental variable @LI{COLUMNS}exists, it is used to specify the number of columns in the screen. @item The TIOCGWINSZ @XR{ioctl,2} is attempted on the standard error file descriptor. @item The termcap entry (or terminfo entry on System V machines) is checked for the @QQ{li} entry (rows) and the @QQ{co} entry (columns). @item The number of rows is set to 24, and the number of columns is set to 80. @end enumerate If a window change size signal (SIGWINCH) is received, the new window size is retrieved using the TIOCGWINSZ @XR{ioctl,2} call, and all other information is ignored. @chapter Character Display In both @CO{ex} and @CO{vi} printable characters as defined by @XR{isprint,3} are displayed using the local character set. Non-printable characters, for which @XR{iscntrl,3} returns true, and which are less than octal \e040, are displayed as the string @QT{^}, where @LI{}is the character that is the original character's value offset from the @QT{@@} character. For example, the octal character \e001 is displayed as @QT{^A}. If @XR{iscntrl,3} returns true for the octal character \e177, it is displayed as the string @QT{^?}. All other characters are displayed as either hexadecimal values, in the form @QT{0x ... 0x}, or as octal values, in the form @QT{\e ... \e}. The display of unknown characters is based on the value of the @OP{octal} option. In @CO{vi} command mode, the cursor is always positioned on the last column of characters which take up more than one column on the screen. In @CO{vi} text input mode, the cursor is positioned on the first column of characters which take up more than one column on the screen. @chapter Multiple Screens @CO{Nvi} supports multiple screens by dividing the window into regions. It also supports stacks of screens by permitting the user to change the set of screens that are currently displayed. The @CO{Edit} , @CO{Ex} , @CO{Fg} , @CO{Next} , @CO{Previous} , @CO{Tag} and @CO{Visual} (in @CO{vi} mode) commands divide the current screen into two regions of approximately equal size and then perform their usual action in a new screen area. If the cursor is in the lower half of the screen, the screen will split up, i.e.@: the new screen will be above the old one. If the cursor is in the upper half of the screen, the new screen will be below the old one. When more than one screen is editing a file, changes in any screen are reflected in all other screens editing the same file. Exiting a screen without saving any changes (or explicitly discarding them) is permitted until the last screen editing the file is exited, at which time the changes must be saved or discarded. The @CO{resize} command permits resizing of individual screens. Screens may be grown, shrunk or set to an absolute number of rows. The @CO{^W} command is used to switch between screens. Each @CO{^W} moves to the next lower screen in the window, or to the first screen in the window if there are no lower screens. The @CO{bg} command @QQ{backgrounds} the current screen. The screen disappears from the window, and the rows it occupied are taken over by a neighboring screen. It is an error to attempt to background the only screen in the window. The @CO{display screens} command displays the names of the files associated with the current backgrounded screens in the window. The @CO{fg [file]} command moves the specified screen from the list of backgrounded screens to the foreground. If no file argument is specified, the first screen on the list is foregrounded. By default, foregrounding consists of backgrounding the current screen, and replacing its space in the window with the foregrounded screen. Capitalizing the first letter of the command, i.e.@: @CO{Fg} , will foreground the backgrounded screen in a new screen instead of swapping it with the current screen. If the last foregrounded screen in the window is exited, and there are backgrounded screens, the first screen on the list of backgrounded screens takes over the window. @chapter Tags, Tag Stacks, and Cscope @CO{Nvi} supports the historic @CO{vi} tag command @CO{} , and the historic @CO{ex} tag command @CO{tag} . These commands change the current file context to a new location, based on information found in the @LI{tags}files. If you are unfamiliar with these commands, you should review their description in the @CO{ex} and @CO{vi} commands section of this manual. For additional information on tags files, see the discussion of the @OP{tags} edit option and the system @XR{ctags,1} manual page. In addition, @CO{nvi} supports the notion of @QQ{tags stacks}, using the @CO{} command. The @CO{} command returns the user to the previous context, i.e., the last place from which a @CO{} or @CO{tag} command was entered. These three commands provide the basic functionality which allows you to use @CO{vi} to review source code in a structured manner. @CO{Nvi} also provides two other basic @CO{ex} commands for tag support: @CO{tagpop} and @CO{tagtop} . The @CO{tagpop} command is identical to the @CO{} command, with the additional functionality that you may specify that modifications to the current file are to be discarded. This cannot be done using the @CO{} command. The @CO{tagtop} command discards all of the contexts that have been pushed onto the tag stack, returning to the context from which the first @CO{} or @CO{tag} command was entered. The historic @XR{ctags,1} tags file format supports only a single location per tag, normally the function declaration or structure or string definition. More sophisticated source code tools often provide multiple locations per tag, e.g., a list of the places from which a function is called or a string definition is used. An example of this functionality is the System V source code tool, @CO{cscope} . @sp 1 @CO{Cscope} creates a database of information on source code files, and supports a query language for that information as described in the @XR{cscope,1} manual page. @CO{Nvi} contains an interface to the @CO{cscope} query language which permits you to query @CO{cscope} and then sequentially step through the locations in the sources files which @CO{cscope} returns. There are two @CO{nvi} commands which support this ability to step through multiple locations. They are the @CO{ex} commands @CO{tagnext} and @CO{tagprev} . The @CO{tagnext} command moves to the next location for the current tag. The @CO{tagprev} command moves to the previous location for the current tag. (See the @CO{tagnext} and @CO{tagprev} command discussion in the @CO{ex} commands section of this manual for more information.) At any time during this sequential walk, you may use the @CO{} , @CO{tag} or @CO{cscope} commands to move to a new tag context, and then use the @CO{} or @CO{tagpop} commands to return and continue stepping through the locations for this tag. This is similar to the previous model of a simple tag stack, except that each entry in the tag stack may have more than one file context that is of interest. Although there is no widely distributed version of @XR{ctags,1} that creates tags files with multiple locations per tag, @CO{nvi} has been written to understand the obvious extension to the historic tags file format, i.e., more than a single line in the tags file with the same initial tag name. If you wish to extend your @CO{ctags} implementation or other tool with which you build tags files, this extension should be simple and will require no changes to @CO{nvi} . The @CO{nvi} and @CO{cscope} interface is based on the new @CO{ex} command @CO{cscope} , which has five subcommands: @CO{add} , @CO{find} , @CO{help} , @CO{kill} and @CO{reset} . The subcommand @CO{find} itself has eight subcommands: @CO{c} , @CO{d} , @CO{e} , @CO{f} , @CO{g} , @CO{i} , @CO{s} and @CO{t} . @itemize @bullet @IP{cs[cope] a[dd] file} The @CO{add} command attaches to the specified @CO{cscope} database. The file name is expanded using the standard filename expansions. If @CO{file} is a directory, the file @QQ{cscope.out} in that directory is used as the database. After @CO{nvi} attaches to a new database, all subsequent @CO{cscope} queries will be asked of that database. The result of any single query is the collection of response to the query from all of the attached databases. @sp 1 If the @QQ{CSCOPE_DIRS} environmental variable is set when @CO{nvi} is run, it is expected to be a or -separated list of @CO{cscope} databases or directories containing @CO{cscope} databases, to which the user wishes to attach. @IP{:cs[cope] f[ind] c|d|e|f|g|i|s|t buffer|pattern} The @CO{find} command is the @CO{cscope} query command for @CO{nvi} . For this command, @CO{nvi} queries all attached @CO{cscope} databases for the pattern. If the pattern is a double-quote character followed by a valid buffer name (e.g., @LI{}"" ), then the contents of the named buffer are used as the pattern. Otherwise, the pattern is a Regular Expression. @sp 1 The @CO{find} command pushes the current location onto the tags stack, and switches to the first location resulting from the query, if the query returned at least one result. @sp 1 File names returned by the @CO{cscope} query, if not absolute paths, are searched for relative to the directory where the @CO{cscope} database is located. In addition, if the file @QQ{cscope.tpath} appears in the same directory as the @CO{cscope} database, it is expected to contain a colon-separated list of directory names where files referenced by its associated @CO{cscope} database may be found. @sp 1 The @CO{find} subcommand is one of the following: @table @asis @item c Find callers of the name. @item d Find all function calls made from name. @item e Find pattern. @item f Find files with name as substring. @item g Find definition of name. @item i Find files #including name. @item s Find all uses of name. @item t Find assignments to name. @end table @IP{:cs[cope] h[elp] [command]} List the @CO{cscope} commands, or optionally list usage help for any single @CO{cscope} command. @IP{:display c[onnections]} Display the list of @CO{cscope} databases to which @CO{nvi} is currently connected. @IP{:cs[cope] k[ill] #} Disconnect from a specific @CO{cscope} database. The connection number is the one displayed by the @CO{ex} @CO{display connections} command. @IP{:cs[cope] r[eset]} Disconnect from all attached @CO{cscope} databases. @end itemize Cscope is not freely redistributable software, but is fairly inexpensive and easily available. To purchase a copy of @CO{cscope} , see http://www.att.com/ssg/products/toolchest.html. @chapter Regular Expressions and Replacement Strings Regular expressions are used in line addresses, as the first part of the @CO{ex} @CO{substitute} , @CO{global} , and @CO{v} commands, and in search patterns. The regular expressions supported by @EV{ex,vi} are, by default, the Basic Regular Expressions (BRE's) described in the IEEE POSIX Standard 1003.2. The @OP{extended} option causes all regular expressions to be interpreted as the Extended Regular Expressions (ERE's) described by the same standard. (See @XR{re_format,7} for more information.) Generally speaking, BRE's are the Regular Expressions found in @XR{ed,1} and @XR{grep,1}, and ERE's are the Regular Expressions found in @XR{egrep,1}. The following is not intended to provide a description of Regular Expressions. The information here only describes strings and characters which have special meanings in the @EV{ex,vi} version of RE's, or options which change the meanings of characters that normally have special meanings in RE's. @enumerate @item An empty RE (e.g. @QT{//} or @QT{??} is equivalent to the last RE used. @item The construct @QT{\e<} matches the beginning of a word. @item The construct @QT{\e>} matches the end of a word. @item The character @QT{~} matches the replacement part of the last @CO{substitute} command. @end enumerate When the @OP{magic} option is @emph{not} set, the only characters with special meanings are a @QT{^} character at the beginning of an RE, a @QT{$} character at the end of an RE, and the escaping character @QT{\e}. The characters @QT{.}, @QT{*}, @QT{[} and @QT{~} are treated as ordinary characters unless preceded by a @QT{\e}; when preceded by a @QT{\e} they regain their special meaning. Replacement strings are the second part of a @CO{substitute} command. The character @QT{&} (or @QT{\e&} if the @OP{magic} option is @emph{not} set) in the replacement string stands for the text matched by the RE that is being replaced. The character @QT{~} (or @QT{\e~} if the @OP{magic} option is @emph{not} set) stands for the replacement part of the previous @CO{substitute} command. It is only valid after a @CO{substitute} command has been performed. The string @QT{\e#}, where @QT{#} is an integer value from 1 to 9, stands for the text matched by the portion of the RE enclosed in the @QT{#}'th set of escaped parentheses, e.g. @QT{\e(} and @QT{\e)}. For example, @QT{s/abc\e(.*\e)def/\e1/} deletes the strings @QT{abc} and @QT{def} from the matched pattern. The strings @QT{\el}, @QT{\eu}, @QT{\eL} and @QT{\eU} can be used to modify the case of elements in the replacement string. The string @QT{\el} causes the next character to be converted to lowercase; the string @QT{\eu} behaves similarly, but converts to uppercase (e.g. @LI{s/abc/\eU&/}replaces the string @LI{abc}with @LI{ABC}). The string @QT{\eL} causes characters up to the end of the string or the next occurrence of the strings @QT{\ee} or @QT{\eE} to be converted to lowercase; the string @QT{\eU} behaves similarly, but converts to uppercase. If the entire replacement pattern is @QT{%}, then the last replacement pattern is used again. In @CO{vi} , inserting a @LI{}into the replacement string will cause the matched line to be split into two lines at that point. (The @LI{}will be discarded.) @chapter Scripting Languages The @CO{nvi} editor currently supports two scripting languages, Tcl/Tk and Perl. (Note that Perl4 isn't sufficient, and that the Perl5 used must be version 5.002 or later. See the @QB{Building Nvi} section for more information. The scripting language interface is still being worked on, therefore the following information is probably incomplete, probably wrong in cases, and likely to change. See the @LI{perl_api}and @LI{tcl_api}source directories for more information. As a quick reference, the following function calls are provided for both the Perl and Tcl interfaces. The Perl interface uses a slightly different naming convention, e.g. ``viFindScreen'' is named ``VI::FindScreen''. @itemize @bullet @IP{viFindScreen file} Return the @LI{screenId}associated with @LI{file}. @IP{viAppendLine screenId lineNumber text} Append @LI{text}as a new line after line number @LI{lineNumber}, in the screen @LI{screenId}. @IP{viDelLine screenId lineNum} Delete the line @LI{lineNumber}from the screen @LI{screenId}. @IP{viGetLine screenId lineNumber} Return the line @LI{lineNumber}from the screen @LI{screenId}. @IP{viInsertLine screenId lineNumber text} Insert @LI{text}as a new line before line number @LI{lineNumber}in the screen @LI{screenId}. @IP{viLastLine screenId} Return the line number of the last line in the screen @LI{screenId}. @IP{viSetLine screenId lineNumber text} Change the line @LI{lineNumber}in the screen @LI{screenId}to match the specified @LI{text}. @IP{viGetMark screenId mark} Return the current line and column for the specified @LI{mark}from the screen @LI{screenId}. @IP{viSetMark screenId mark line column} Set the specified @LI{mark}to be at line @LI{line}, column @LI{column}, in the screen @LI{screenId}. @IP{viGetCursor screenId} Return the current line and column for the cursor in the screen @LI{screenId}. @IP{viSetCursor screenId line column} Set the cursor in the screen @LI{screenId}to the specified @LI{line}and @LI{column}. @IP{viMsg screenId text} Display the specified @LI{text}as a vi message in the screen @LI{screenId}. @IP{viNewScreen screenId [file]} Create a new screen. @IP{viEndScreen screenId} Exit the screen @LI{screenId}. @IP{viSwitchScreen screenId screenId} Switch from the screen @LI{screenId}to the screen @LI{screenId}. @IP{viMapKey screenId key tclproc} Map the specified @LI{key}in the screen @LI{screenId}to the Tcl procedure @LI{tclproc}. @IP{viUnmMapKey screenId key} Unmap the specified @LI{key}in the screen @LI{screenId}@IP{viGetOpt screenId option} Return the value of the specified @LI{option}from the screen @LI{screenId}. @IP{viSetOpt screenId command} Set one or more options in the screen @LI{screenId}. @end itemize @chapter General Editor Description When @CO{ex} or @CO{vi} are executed, the text of a file is read (or a temporary file is created), and then all editing changes happen within the context of the copy of the file. @emph{No changes affect the actual file until the file is written out}, either using a write command or another command which is affected by the @OP{autowrite} option. All files are locked (using the @XR{flock,2} or @XR{fcntl,2} interfaces) during the edit session, to avoid inadvertently making modifications to multiple copies of the file. If a lock cannot be obtained for a file because it is locked by another process, the edit session is read-only (as if the @OP{readonly} option or the @strong{-R} flag had been specified). If a lock cannot be obtained for other reasons, the edit session will continue, but the file status information (see the @CO{} command) will reflect this fact. Both @CO{ex} and @CO{vi} are modeful editors, i.e.@: they have two modes, @QQ{command} mode and @QQ{text input} mode. The former is intended to permit you to enter commands which modifies already existing text. The latter is intended to permit you to enter new text. When @CO{ex} first starts running, it is in command mode, and usually displays a prompt (see the @OP{prompt} option for more information). The prompt is a single colon @PQ{:} character. There are three commands that switch @CO{ex} into text input mode: @CO{append} , @CO{change} and @CO{insert} . Once in input mode, entering a line containing only a single period @PQ{.} ends text input mode and returns to command mode, where the prompt is redisplayed. When @CO{vi} first starts running, it is in command mode as well. There are eleven commands that switch @CO{vi} into text input mode: @CO{A} , @CO{a} , @CO{C} , @CO{c} , @CO{I} , @CO{i} , @CO{O} , @CO{o} , @CO{R} , @CO{S} and @CO{s} . Once in input mode, entering an @LI{}character ends text input mode and returns to command mode. @EV{Ex,vi} present three different interfaces to editing a file. @CO{Ex} presents a line oriented interface. @CO{Vi} presents a full screen display oriented interface, also known as @QQ{visual mode}. In addition, there is a third mode, @QQ{open mode}, which is line oriented, but supports cursor movement and editing within the displayed line, similarly to visual mode. Open mode is not yet implemented in @CO{nvi} . The following words have special meanings in both the @CO{ex} and @CO{vi} command descriptions: @itemize @bullet @cindex @IP{} The interrupt character is used to interrupt the current operation. Normally @LI{}, whatever character is set for the current terminal is used. @cindex "" @IP{} The literal next character is used to escape the subsequent character from any special meaning. This character is always @LI{}. If the terminal is not set up to do XON/XOFF flow control, then @LI{}is used to mean literal next as well. @cindex "current pathname" @IP{current pathname} The pathname of the file currently being edited by vi. When the percent character @PQ{%} appears in a file name entered as part of an @CO{ex} command argument, it is replaced by the current pathname. (The @QT{%} character can be escaped by preceding it with a backslash.) @cindex "alternate pathname" @IP{alternate pathname} The name of the last file name mentioned in an @CO{ex} command, or, the previous current pathname if the last file mentioned becomes the current file. When the hash mark character @PQ{#} appears in a file name entered as part of an @CO{ex} command argument, it is replaced by the alternate pathname. (The @QT{#} character can be escaped by preceding it with a backslash.) @cindex buffer @IP{buffer} One of a number of named areas for saving copies of text. Commands that change or delete text can save the changed or deleted text into a specific buffer, for later use, if the command allows it (i.e.@: the @CO{ex} @CO{change} command cannot save the changed text in a named buffer). Buffers are named with a single character, preceded by a double quote, e.g. @LI{}"" in @CO{vi} and without the double quote, e.g. @LI{}, in @CO{ex} . (The double quote isn't necessary for @CO{ex} because buffers names are denoted by their position in the command line.) Historic implementations of @EV{ex,vi} limited @LI{}to the alphanumeric characters; @EV{nex,nvi} permits the use of any character without another meaning in the position where a buffer name is expected. @sp 1 Buffers named by uppercase characters are the same as buffers named by lowercase characters, e.g. the buffer named by the English character @QT{A} is the same as the buffer named by the character @QT{a}, with the exception that, if the buffer contents are being changed (as with a text deletion or @CO{vi} @CO{change} command), the text is @emph{appended} to the buffer, instead of replacing the current contents. @sp 1 The buffers named by the numeric characters (in English, @QT{1} through @QT{9}), are special. If a region of text including characters from more than one line, or a single line of text specified by using a line-oriented motion, is changed or deleted in the file using the @CO{vi} @CO{change} or @CO{delete} commands, a copy of the text is placed into the numeric buffer @QT{1}, regardless of the user specifying another buffer in which to save it. In addition, there are a few commands which, when used as a @LI{motion}with the @CO{vi} @CO{change} and @CO{delete} commands, @emph{always} copy the specified region of text into the numeric buffers regardless of the region including characters from more than one line. These commands are: @sp 1 @multitable {@CO{'}} {@CO{AA}} {@CO{AA}} {@CO{AA}} @item @CO{} @tab @CO{%} @tab @CO{(} @tab @CO{)} @item @CO{`} @tab @CO{/} @tab @CO{?} @tab @CO{N} @item @CO{n} @tab @strong{@{} @tab @strong{@}} @end multitable @sp 1 Before this copy is done, the previous contents of buffer @QT{1} are moved into buffer @QT{2}, @QT{2} into buffer @QT{3}, and so on. The contents of buffer @QT{9} are discarded. In @CO{vi} , text may be explicitly stored into the numeric buffers. In this case, the buffer rotation described above occurs before the replacement of the buffer's contents. The numeric buffers are only available in @LI{visual}and @LI{open}modes, and are not accessible by @CO{ex} in any way, although changed and deleted text is still stored there while in @CO{ex} mode. @sp 1 When a @CO{vi} command synopsis shows both a @LI{[buffer]}and a @LI{[count]}, they may be presented in any order. @sp 1 Finally, all buffers are either @QQ{line} or @QQ{character} oriented. All @CO{ex} commands which store text into buffers are line oriented. Some @CO{vi} commands which store text into buffers are line oriented, and some are character oriented; the description for each applicable @CO{vi} command notes whether text copied into buffers using the command is line or character oriented. In addition, the @CO{vi} command @CO{display buffers} displays the current orientation for each buffer. Generally, the only importance attached to this orientation is that if the buffer is subsequently inserted into the text, line oriented buffers create new lines for each of the lines they contain, and character oriented buffers create new lines for any lines @emph{other} than the first and last lines they contain. The first and last lines are inserted into the text at the current cursor position, becoming part of the current line. If there is more than one line in the buffer, however, the current line itself will be split. @cindex "unnamed buffer" @IP{unnamed buffer} The unnamed buffer is a text storage area which is used by commands that use or operate on a buffer when no buffer is specified by the user. If the command stores text into a buffer, the text is stored into the unnamed buffer even if a buffer is also specified by the user. It is not possible to append text to the unnamed buffer. If text is appended to a named buffer, the named buffer contains both the old and new text, while the unnamed buffer contains only the new text. There is no way to explicitly reference the unnamed buffer. @sp 1 Historically, the contents of the unnamed buffer were discarded by many different commands, even ones that didn't store text into it. @EV{Nex,nvi} never discards the contents of the unnamed buffer until new text replaces them. @cindex whitespace @IP{whitespace} The characters and . @cindex "" @IP{} The character represented by an ASCII @LI{}. This character is almost always treated identically to a @LI{}character, but differs in that it can be escaped into the file text or into a command. @cindex @IP{} The character represented by an ASCII @LI{}. This character is almost always treated identically to a @LI{}character, but differs in that it cannot be escaped into the file text or into a command. @end itemize @comment .oh 'Vi/Ex Reference (Vi Commands)''USD:13-%' @comment .eh 'USD:13-%''Vi/Ex Reference (Vi Commands)' @include vi.cmd.texi @comment .oh 'Vi/Ex Reference''USD:13-%' @comment .eh 'USD:13-%''Vi/Ex Reference' @chapter Ex Addressing Addressing in @CO{ex} (and when @CO{ex} commands are executed from @CO{vi} ) relates to the current line. In general, the current line is the last line affected by a command. The exact effect on the current line is discussed under the description of each command. When the file contains no lines, the current line is zero. Addresses are constructed by one or more of the following methods: @enumerate @item The address @QT{.} refers to the current line. @item The address @QT{$} refers to the last line of the file. @item The address @QT{N}, where @LI{N}is a positive number, refers to the N-th line of the file. @item The address @QT{'} or @QT{`} refers to the line marked with the name @LI{}. (See the @CO{k} or @CO{m} commands for more information on how to mark lines.) @item A regular expression (RE) enclosed by slashes @PQ{/} is an address, and it refers to the first line found by searching forward from the line @emph{after} the current line toward the end of the file, and stopping at the first line containing a string matching the RE. (The trailing slash can be omitted at the end of the command line.) @sp 1 If no RE is specified, i.e.@: the pattern is @QT{//}, the last RE used in any command is used in the search. @sp 1 If the @OP{extended} option is set, the RE is handled as an extended RE, not a basic RE. If the @OP{wrapscan} option is set, the search wraps around to the beginning of the file and continues up to and including the current line, so that the entire file is searched. @sp 1 The form @QT{\e/} is accepted for historic reasons, and is identical to @QT{//}. @item An RE enclosed in question marks @PQ{?} addresses the first line found by searching backward from the line @emph{preceding} the current line, toward the beginning of the file and stopping at the first line containing a string matching the RE. (The trailing question mark can be omitted at the end of a command line.) @sp 1 If no RE is specified, i.e.@: the pattern is @QT{??}, the last RE used in any command is used in the search. @sp 1 If the @OP{extended} option is set, the RE is handled as an extended RE, not a basic RE. If the @OP{wrapscan} option is set, the search wraps around from the beginning of the file to the end of the file and continues up to and including the current line, so that the entire file is searched. @sp 1 The form @QT{\e?} is accepted for historic reasons, and is identical to @QT{??}. @item An address followed by a plus sign @PQ{+} or a minus sign @PQ{-} followed by a number is an offset address and refers to the address plus (or minus) the indicated number of lines. If the address is omitted, the addition or subtraction is done with respect to the current line. @item An address of @QT{+} or @QT{-} followed by a number is an offset from the current line. For example, @QT{-5} is the same as @QT{.-5}. @item An address ending with @QT{+} or @QT{-} has 1 added to or subtracted from the address, respectively. As a consequence of this rule and of the previous rule, the address @QT{-} refers to the line preceding the current line. Moreover, trailing @QT{+} and @QT{-} characters have a cumulative effect. For example, @QT{++-++} refers to the current line plus 3. @item A percent sign @PQ{%} is equivalent to the address range @QT{1,$}. @end enumerate @CO{Ex} commands require zero, one, or two addresses. It is an error to specify an address to a command which requires zero addresses. If the user provides more than the expected number of addresses to any @CO{ex} command, the first addresses specified are discarded. For example, @QT{1,2,3,5}print prints lines 3 through 5, because the @CO{print} command only takes two addresses. The addresses in a range are separated from each other by a comma @PQ{,} or a semicolon @PQ{;}. In the latter case, the current line @PQ{.} is set to the first address, and only then is the second address calculated. This feature can be used to determine the starting line for forward and backward searches (see rules (5) and (6) above). The second address of any two-address sequence corresponds to a line that follows, in the file, the line corresponding to the first address. The first address must be less than or equal to the second address. The first address must be greater than or equal to the first line of the file, and the last address must be less than or equal to the last line of the file. @comment .oh 'Vi/Ex Reference (Ex Commands)''USD:13-%' @comment .eh 'USD:13-%''Vi/Ex Reference (Ex Commands)' @include ex.cmd.texi @comment .oh 'Vi/Ex Reference (Options)''USD:13-%' @comment .eh 'USD:13-%''Vi/Ex Reference (Options)' @include set.opt.texi @comment .oh 'Vi/Ex Reference''USD:13-%' @comment .eh 'USD:13-%''Vi/Ex Reference' @page @chapter Index @printindex cp @comment Force the TOC to an odd page, in case it's a duplex printer. @bye nvi-1.81.6/docs/vi.ref/vi.ref.txt0100444000076400001440000057302110720065721015532 0ustar skimousers1 Description ************* *Vi* is a screen oriented text editor. *Ex* is a line-oriented text editor. *Ex* and *vi* are different interfaces to the same program, and it is possible to switch back and forth during an edit session. *View* is the equivalent of using the *-R* (read-only) option of *vi* . This reference manual is the one provided with the *nex*/*nvi* versions of the *ex*/*vi* text editors. *Nex*/*nvi* are intended as bug-for-bug compatible replacements for the original Fourth Berkeley Software Distribution (4BSD) *ex*/*vi* programs. This reference manual is accompanied by a traditional-style manual page. That manual page describes the functionality found in *ex*/*vi* in far less detail than the description here. In addition, it describes the system interface to *ex*/*vi*, e.g. command line options, session recovery, signals, environmental variables, and similar things. This reference is intended for users already familiar with *ex*/*vi*. Anyone else should almost certainly read a good tutorial on the editor first. If you are in an unfamiliar environment, and you absolutely have to get work done immediately, see the section entitled "*Fast Startup*" in the manual page. It is probably enough to get you started. There are a few features in *nex*/*nvi* that are not found in historic versions of *ex*/*vi*. Some of the more interesting of those features are briefly described in the next section, entitled "*Additional Features*" . For the rest of this document, *nex*/*nvi* is used only when it is necessary to distinguish it from the historic implementations of *ex*/*vi*. Future versions of this software will be periodically made available by anonymous ftp, and can be retrieved from `ftp.cs.berkeley.edu', in the directory `ucb/4bsd'. 2 Additional Features in Nex/Nvi ******************************** There are a few features in *nex*/*nvi* that are not found in historic versions of *ex*/*vi*. Some of the more interesting of these are as follows: * *8-bit clean data, large lines, files* *Nex*/*nvi* will edit any format file. Line lengths are limited by available memory, and file sizes are limited by available disk space. The *vi* text input mode command ** can insert any possible character value into the text. * *Background and foreground screens* The *bg* command backgrounds the current screen, and the *fg* command foregrounds backgrounded screens. The *display* command can be used to list the background screens. * *Command Editing* You can enter a normal editing window on the collected commands that you've entered on the *vi* colon command-line, and then modify and/or execute the commands. See the `cedit' edit option for more information. * *Displays* The *display* command can be used to display the current buffers, the backgrounded screens, and the tags stack. * *Extended Regular Expressions* The *extended* option causes Regular Expressions to be interpreted as as Extended Regular Expressions, (i.e. `egrep'(1) style Regular Expressions). * *File Name Completion* It is possible to do file name completion and file name displays when entering commands on the *vi* colon command-line. See the `filec' option for more information. * *Infinite undo* Changes made during an edit session may be rolled backward and forward. A *.* command immediately after a *u* command continues either forward or backward depending on whether the *u* command was an undo or a redo. * *Left-right scrolling* The *leftright* option causes *nvi* to do left-right screen scrolling, instead of the traditional *vi* line wrapping. * *Message Catalogs* It is possible to display informational and error messages in different languages by providing a catalog of messages. See the `msgcat' option and the file `catalog/README'for more information. * *Incrementing numbers* The *#* command increments or decrements the number referenced by the cursor. * *Previous file* The *previous* command edits the previous file from the argument list. * *Scripting languages* The *:pe[rl] cmd*, *:perld[o] cmd* and *:tc[l] cmd* commands execute Perl and Tcl/Tk commands, respectively, on lines from the edit buffer. See the "*Scripting Languages*" section and the specific commands for more information. * *Split screens* The *Edit* , *Ex* , *Next* , *Previous* , *Tag* and *Visual* (in *vi* mode) commands divide the screen into multiple editing regions and then perform their normal function in a new screen area. The ** command rotates between the foreground screens. The *resize* command can be used to grow or shrink a particular screen. * *Tag stacks* Tags are now maintained in a stack. The ** command returns to the previous tag location. The *tagpop* command returns to the most recent tag location by default, or, optionally to a specific tag number in the tag stack, or the most recent tag from a specified file. The *display* command can be used to list the tags stack. The *tagtop* command returns to the top of the tag stack. * *Usage information* The *exusage* and *viusage* commands provide usage information for all of the *ex* and *vi* commands by default, or, optionally, for a specific command or key. * *Word search* The ** command searches for the word referenced by the cursor. 3 Startup Information ********************* *Ex*/*vi* interprets one of two possible environmental variables and reads up to three of five possible files during startup. The variables and files are expected to contain *ex* commands, not *vi* commands. In addition, they are interpreted _before_ the file to be edited is read, and therefore many *ex* commands may not be used. Generally, any command that requires output to the screen or that needs a file upon which to operate, will cause an error if included in a startup file or environmental variable. Because the *ex* command set supported by *nex*/*nvi* is a superset of the command set supported by historical implementations of *ex* , *nex*/*nvi* can use the startup files created for the historical implementations, but the converse may not be true. If the *-s* (the historic - option) is specified, or if standard input is redirected from a file, all environmental variables and startup files are ignored. Otherwise, startup files and environmental variables are handled in the following order: 1. The file `/etc/vi.exrc'is read, as long as it is owned by root or the effective user ID of the user. 2. The environmental variable `NEXINIT'(or the variable `EXINIT', if `NEXINIT'is not set) is interpreted. 3. If neither `NEXINIT'or `EXINIT'was set, and the `HOME'environmental variable is set, the file `$HOME/.nexrc'(or the file `$HOME/.exrc', if `$HOME/.nexrc'does not exist) is read, as long as the effective user ID of the user is root or is the same as the owner of the file. When the $HOME directory is being used for both *nex*/*nvi* and an historic implementation of *ex*/*vi*, a possible solution is to put *nex*/*nvi* specific commands in the `.nexrc'file, along with a *:source $HOME/.exrc* command to read in the commands common to both implementations. 4. If the `exrc' option was turned on by one of the previous startup information sources, the file `.nexrc'(or the file `.exrc', if `.nexrc'does not exist) is read, as long as the effective user ID of the user is the same as the owner of the file. No startup file is read if it is writable by anyone other than its owner. It is not an error for any of the startup environmental variables or files not to exist. Once all environmental variables are interpreted, and all startup files are read, the first file to be edited is read in (or a temporary file is created). Then, any commands specified using the *-c* option are executed, in the context of that file. 4 Recovery ********** There is no recovery program for *nex*/*nvi*, nor does *nex*/*nvi* run setuid. Recovery files are created readable and writable by the owner only. Users may recover any file which they can read, and the superuser may recover any edit session. Edit sessions are backed by files in the directory named by the `recdir' option (the directory `/var/tmp/vi.recover'by default), and are named "*vi.XXXXXX*", where "*XXXXXX*" is a number related to the process ID. When a file is first modified, a second recovery file containing an email message for the user is created, and is named "*recover.XXXXXX*", where, again, "*XXXXXX*" is associated with the process ID. Both files are removed at the end of a normal edit session, but will remain if the edit session is abnormally terminated or the user runs the *ex* *preserve* command. The `recdir' option may be set in either the user's or system's startup information, changing the recovery directory. (Note, however, that if a memory based file system is used as the backup directory, each system reboot will delete all of the recovery files! The same caution applies to directories such as `/tmp'which are cleared of their contents by a system reboot, or `/usr/tmp'which is periodically cleared of old files on many systems.) The recovery directory should be owned by root, or at least by a pseudo-user. In addition, if directory "sticky-bit" semantics are available, the directory should have the sticky-bit set so that files may only be removed by their owners. The recovery directory must be read, write, and executable by any user, i.e. mode 1777. If the recovery directory does not exist, *ex*/*vi* will attempt to create it. This can result in the recovery directory being owned by a normal user, which means that that user will be able to remove other user's recovery and backup files. This is annoying, but is not a security issue as the user cannot otherwise access or modify the files. The recovery file has all of the necessary information in it to enable the user to recover the edit session. In addition, it has all of the necessary email headers for `sendmail'(8). When the system is rebooted, all of the files in `/var/tmp/vi.recover'named "*recover.XXXXXX*" should be sent to their owners, by email, using the *-t* option of *sendmail* (or a similar mechanism in other mailers). If *ex*/*vi* receives a hangup (SIGHUP) signal, or the user executes the *ex* *preserve* command, *ex*/*vi* will automatically email the recovery information to the user. If your system does not have the *sendmail* utility (or a mailer program which supports its interface) the source file `nvi/common/recover.c'will have to be modified to use your local mail delivery programs. Note, if *nex*/*nvi* is changed to use another mailer, it is important to remember that the owner of the file given to the mailer is the *nex*/*nvi* user, so nothing in the file should be trusted as it may have been modified in an effort to compromise the system. Finally, the owner execute bit is set on backup files when they are created, and unset when they are first modified, e.g. backup files that have no associated email recovery file will have this bit set. (There is also a small window where empty files can be created and not yet have this bit set. This is due to the method in which the files are created.) Such files should be deleted when the system reboots. A simple way to do this cleanup is to run the Bourne shell script *recover* , from your `/etc/rc.local'(or other system startup) file. The script should work with the historic Bourne shell, a POSIX 1003.2 shell or the Korn shell. The *recover* script is installed as part of the *nex*/*nvi* installation process. Consult the manual page for details on recovering preserved or aborted editing sessions. 5 Sizing the Screen ******************* The size of the screen can be set in a number of ways. *Ex*/*vi* takes the following steps until values are obtained for both the number of rows and number of columns in the screen. 1. If the environmental variable `LINES'exists, it is used to specify the number of rows in the screen. 2. If the environmental variable `COLUMNS'exists, it is used to specify the number of columns in the screen. 3. The TIOCGWINSZ `ioctl'(2) is attempted on the standard error file descriptor. 4. The termcap entry (or terminfo entry on System V machines) is checked for the "li" entry (rows) and the "co" entry (columns). 5. The number of rows is set to 24, and the number of columns is set to 80. If a window change size signal (SIGWINCH) is received, the new window size is retrieved using the TIOCGWINSZ `ioctl'(2) call, and all other information is ignored. 6 Character Display ******************* In both *ex* and *vi* printable characters as defined by `isprint'(3) are displayed using the local character set. Non-printable characters, for which `iscntrl'(3) returns true, and which are less than octal \e040, are displayed as the string "`^'", where `'is the character that is the original character's value offset from the "`@'" character. For example, the octal character \e001 is displayed as "`^A'". If `iscntrl'(3) returns true for the octal character \e177, it is displayed as the string "`^?'". All other characters are displayed as either hexadecimal values, in the form "`0x ... 0x'", or as octal values, in the form "`e ... e'". The display of unknown characters is based on the value of the `octal' option. In *vi* command mode, the cursor is always positioned on the last column of characters which take up more than one column on the screen. In *vi* text input mode, the cursor is positioned on the first column of characters which take up more than one column on the screen. 7 Multiple Screens ****************** *Nvi* supports multiple screens by dividing the window into regions. It also supports stacks of screens by permitting the user to change the set of screens that are currently displayed. The *Edit* , *Ex* , *Fg* , *Next* , *Previous* , *Tag* and *Visual* (in *vi* mode) commands divide the current screen into two regions of approximately equal size and then perform their usual action in a new screen area. If the cursor is in the lower half of the screen, the screen will split up, i.e. the new screen will be above the old one. If the cursor is in the upper half of the screen, the new screen will be below the old one. When more than one screen is editing a file, changes in any screen are reflected in all other screens editing the same file. Exiting a screen without saving any changes (or explicitly discarding them) is permitted until the last screen editing the file is exited, at which time the changes must be saved or discarded. The *resize* command permits resizing of individual screens. Screens may be grown, shrunk or set to an absolute number of rows. The *^W* command is used to switch between screens. Each *^W* moves to the next lower screen in the window, or to the first screen in the window if there are no lower screens. The *bg* command "backgrounds" the current screen. The screen disappears from the window, and the rows it occupied are taken over by a neighboring screen. It is an error to attempt to background the only screen in the window. The *display screens* command displays the names of the files associated with the current backgrounded screens in the window. The *fg [file]* command moves the specified screen from the list of backgrounded screens to the foreground. If no file argument is specified, the first screen on the list is foregrounded. By default, foregrounding consists of backgrounding the current screen, and replacing its space in the window with the foregrounded screen. Capitalizing the first letter of the command, i.e. *Fg* , will foreground the backgrounded screen in a new screen instead of swapping it with the current screen. If the last foregrounded screen in the window is exited, and there are backgrounded screens, the first screen on the list of backgrounded screens takes over the window. 8 Tags, Tag Stacks, and Cscope ****************************** *Nvi* supports the historic *vi* tag command ** , and the historic *ex* tag command *tag* . These commands change the current file context to a new location, based on information found in the `tags'files. If you are unfamiliar with these commands, you should review their description in the *ex* and *vi* commands section of this manual. For additional information on tags files, see the discussion of the `tags' edit option and the system `ctags'(1) manual page. In addition, *nvi* supports the notion of "tags stacks", using the ** command. The ** command returns the user to the previous context, i.e., the last place from which a ** or *tag* command was entered. These three commands provide the basic functionality which allows you to use *vi* to review source code in a structured manner. *Nvi* also provides two other basic *ex* commands for tag support: *tagpop* and *tagtop* . The *tagpop* command is identical to the ** command, with the additional functionality that you may specify that modifications to the current file are to be discarded. This cannot be done using the ** command. The *tagtop* command discards all of the contexts that have been pushed onto the tag stack, returning to the context from which the first ** or *tag* command was entered. The historic `ctags'(1) tags file format supports only a single location per tag, normally the function declaration or structure or string definition. More sophisticated source code tools often provide multiple locations per tag, e.g., a list of the places from which a function is called or a string definition is used. An example of this functionality is the System V source code tool, *cscope* . *Cscope* creates a database of information on source code files, and supports a query language for that information as described in the `cscope'(1) manual page. *Nvi* contains an interface to the *cscope* query language which permits you to query *cscope* and then sequentially step through the locations in the sources files which *cscope* returns. There are two *nvi* commands which support this ability to step through multiple locations. They are the *ex* commands *tagnext* and *tagprev* . The *tagnext* command moves to the next location for the current tag. The *tagprev* command moves to the previous location for the current tag. (See the *tagnext* and *tagprev* command discussion in the *ex* commands section of this manual for more information.) At any time during this sequential walk, you may use the ** , *tag* or *cscope* commands to move to a new tag context, and then use the ** or *tagpop* commands to return and continue stepping through the locations for this tag. This is similar to the previous model of a simple tag stack, except that each entry in the tag stack may have more than one file context that is of interest. Although there is no widely distributed version of `ctags'(1) that creates tags files with multiple locations per tag, *nvi* has been written to understand the obvious extension to the historic tags file format, i.e., more than a single line in the tags file with the same initial tag name. If you wish to extend your *ctags* implementation or other tool with which you build tags files, this extension should be simple and will require no changes to *nvi* . The *nvi* and *cscope* interface is based on the new *ex* command *cscope* , which has five subcommands: *add* , *find* , *help* , *kill* and *reset* . The subcommand *find* itself has eight subcommands: *c* , *d* , *e* , *f* , *g* , *i* , *s* and *t* . * *cs[cope] a[dd] file* The *add* command attaches to the specified *cscope* database. The file name is expanded using the standard filename expansions. If *file* is a directory, the file "cscope.out" in that directory is used as the database. After *nvi* attaches to a new database, all subsequent *cscope* queries will be asked of that database. The result of any single query is the collection of response to the query from all of the attached databases. If the "CSCOPE_DIRS" environmental variable is set when *nvi* is run, it is expected to be a or -separated list of *cscope* databases or directories containing *cscope* databases, to which the user wishes to attach. * *:cs[cope] f[ind] c|d|e|f|g|i|s|t buffer|pattern* The *find* command is the *cscope* query command for *nvi* . For this command, *nvi* queries all attached *cscope* databases for the pattern. If the pattern is a double-quote character followed by a valid buffer name (e.g., `'"" ), then the contents of the named buffer are used as the pattern. Otherwise, the pattern is a Regular Expression. The *find* command pushes the current location onto the tags stack, and switches to the first location resulting from the query, if the query returned at least one result. File names returned by the *cscope* query, if not absolute paths, are searched for relative to the directory where the *cscope* database is located. In addition, if the file "cscope.tpath" appears in the same directory as the *cscope* database, it is expected to contain a colon-separated list of directory names where files referenced by its associated *cscope* database may be found. The *find* subcommand is one of the following: c Find callers of the name. d Find all function calls made from name. e Find pattern. f Find files with name as substring. g Find definition of name. i Find files #including name. s Find all uses of name. t Find assignments to name. * *:cs[cope] h[elp] [command]* List the *cscope* commands, or optionally list usage help for any single *cscope* command. * *:display c[onnections]* Display the list of *cscope* databases to which *nvi* is currently connected. * *:cs[cope] k[ill] #* Disconnect from a specific *cscope* database. The connection number is the one displayed by the *ex* *display connections* command. * *:cs[cope] r[eset]* Disconnect from all attached *cscope* databases. Cscope is not freely redistributable software, but is fairly inexpensive and easily available. To purchase a copy of *cscope* , see http://www.att.com/ssg/products/toolchest.html. 9 Regular Expressions and Replacement Strings ********************************************* Regular expressions are used in line addresses, as the first part of the *ex* *substitute* , *global* , and *v* commands, and in search patterns. The regular expressions supported by *ex*/*vi* are, by default, the Basic Regular Expressions (BRE's) described in the IEEE POSIX Standard 1003.2. The `extended' option causes all regular expressions to be interpreted as the Extended Regular Expressions (ERE's) described by the same standard. (See `re_format'(7) for more information.) Generally speaking, BRE's are the Regular Expressions found in `ed'(1) and `grep'(1), and ERE's are the Regular Expressions found in `egrep'(1). The following is not intended to provide a description of Regular Expressions. The information here only describes strings and characters which have special meanings in the *ex*/*vi* version of RE's, or options which change the meanings of characters that normally have special meanings in RE's. 1. An empty RE (e.g. "`//'" or "`??'" is equivalent to the last RE used. 2. The construct "`e<'" matches the beginning of a word. 3. The construct "`e>'" matches the end of a word. 4. The character "`~'" matches the replacement part of the last *substitute* command. When the `magic' option is _not_ set, the only characters with special meanings are a "`^'" character at the beginning of an RE, a "`$'" character at the end of an RE, and the escaping character "`e'". The characters "`.'", "`*'", "`['" and "`~'" are treated as ordinary characters unless preceded by a "`e'"; when preceded by a "`e'" they regain their special meaning. Replacement strings are the second part of a *substitute* command. The character "`&'" (or "`e&'" if the `magic' option is _not_ set) in the replacement string stands for the text matched by the RE that is being replaced. The character "`~'" (or "`e~'" if the `magic' option is _not_ set) stands for the replacement part of the previous *substitute* command. It is only valid after a *substitute* command has been performed. The string "`e#'", where "`#'" is an integer value from 1 to 9, stands for the text matched by the portion of the RE enclosed in the "`#'"'th set of escaped parentheses, e.g. "`e('" and "`e)'". For example, "`s/abce(.*e)def/e1/'" deletes the strings "`abc'" and "`def'" from the matched pattern. The strings "`el'", "`eu'", "`eL'" and "`eU'" can be used to modify the case of elements in the replacement string. The string "`el'" causes the next character to be converted to lowercase; the string "`eu'" behaves similarly, but converts to uppercase (e.g. `s/abc/eU&/'replaces the string `abc'with `ABC'). The string "`eL'" causes characters up to the end of the string or the next occurrence of the strings "`ee'" or "`eE'" to be converted to lowercase; the string "`eU'" behaves similarly, but converts to uppercase. If the entire replacement pattern is "`%'", then the last replacement pattern is used again. In *vi* , inserting a `'into the replacement string will cause the matched line to be split into two lines at that point. (The `'will be discarded.) 10 Scripting Languages ********************** The *nvi* editor currently supports two scripting languages, Tcl/Tk and Perl. (Note that Perl4 isn't sufficient, and that the Perl5 used must be version 5.002 or later. See the "*Building Nvi*" section for more information. The scripting language interface is still being worked on, therefore the following information is probably incomplete, probably wrong in cases, and likely to change. See the `perl_api'and `tcl_api'source directories for more information. As a quick reference, the following function calls are provided for both the Perl and Tcl interfaces. The Perl interface uses a slightly different naming convention, e.g. "viFindScreen" is named "VI::FindScreen". * *viFindScreen file* Return the `screenId'associated with `file'. * *viAppendLine screenId lineNumber text* Append `text'as a new line after line number `lineNumber', in the screen `screenId'. * *viDelLine screenId lineNum* Delete the line `lineNumber'from the screen `screenId'. * *viGetLine screenId lineNumber* Return the line `lineNumber'from the screen `screenId'. * *viInsertLine screenId lineNumber text* Insert `text'as a new line before line number `lineNumber'in the screen `screenId'. * *viLastLine screenId* Return the line number of the last line in the screen `screenId'. * *viSetLine screenId lineNumber text* Change the line `lineNumber'in the screen `screenId'to match the specified `text'. * *viGetMark screenId mark* Return the current line and column for the specified `mark'from the screen `screenId'. * *viSetMark screenId mark line column* Set the specified `mark'to be at line `line', column `column', in the screen `screenId'. * *viGetCursor screenId* Return the current line and column for the cursor in the screen `screenId'. * *viSetCursor screenId line column* Set the cursor in the screen `screenId'to the specified `line'and `column'. * *viMsg screenId text* Display the specified `text'as a vi message in the screen `screenId'. * *viNewScreen screenId [file]* Create a new screen. * *viEndScreen screenId* Exit the screen `screenId'. * *viSwitchScreen screenId screenId* Switch from the screen `screenId'to the screen `screenId'. * *viMapKey screenId key tclproc* Map the specified `key'in the screen `screenId'to the Tcl procedure `tclproc'. * *viUnmMapKey screenId key* Unmap the specified `key'in the screen `screenId' * *viGetOpt screenId option* Return the value of the specified `option'from the screen `screenId'. * *viSetOpt screenId command* Set one or more options in the screen `screenId'. 11 General Editor Description ***************************** When *ex* or *vi* are executed, the text of a file is read (or a temporary file is created), and then all editing changes happen within the context of the copy of the file. _No changes affect the actual file until the file is written out_, either using a write command or another command which is affected by the `autowrite' option. All files are locked (using the `flock'(2) or `fcntl'(2) interfaces) during the edit session, to avoid inadvertently making modifications to multiple copies of the file. If a lock cannot be obtained for a file because it is locked by another process, the edit session is read-only (as if the `readonly' option or the *-R* flag had been specified). If a lock cannot be obtained for other reasons, the edit session will continue, but the file status information (see the ** command) will reflect this fact. Both *ex* and *vi* are modeful editors, i.e. they have two modes, "command" mode and "text input" mode. The former is intended to permit you to enter commands which modifies already existing text. The latter is intended to permit you to enter new text. When *ex* first starts running, it is in command mode, and usually displays a prompt (see the `prompt' option for more information). The prompt is a single colon "`:'" character. There are three commands that switch *ex* into text input mode: *append* , *change* and *insert* . Once in input mode, entering a line containing only a single period "`.'" ends text input mode and returns to command mode, where the prompt is redisplayed. When *vi* first starts running, it is in command mode as well. There are eleven commands that switch *vi* into text input mode: *A* , *a* , *C* , *c* , *I* , *i* , *O* , *o* , *R* , *S* and *s* . Once in input mode, entering an `'character ends text input mode and returns to command mode. *Ex*/*vi* present three different interfaces to editing a file. *Ex* presents a line oriented interface. *Vi* presents a full screen display oriented interface, also known as "visual mode". In addition, there is a third mode, "open mode", which is line oriented, but supports cursor movement and editing within the displayed line, similarly to visual mode. Open mode is not yet implemented in *nvi* . The following words have special meanings in both the *ex* and *vi* command descriptions: * ** The interrupt character is used to interrupt the current operation. Normally `', whatever character is set for the current terminal is used. * ** The literal next character is used to escape the subsequent character from any special meaning. This character is always `'. If the terminal is not set up to do XON/XOFF flow control, then `'is used to mean literal next as well. * *current pathname* The pathname of the file currently being edited by vi. When the percent character "`%'" appears in a file name entered as part of an *ex* command argument, it is replaced by the current pathname. (The "`%'" character can be escaped by preceding it with a backslash.) * *alternate pathname* The name of the last file name mentioned in an *ex* command, or, the previous current pathname if the last file mentioned becomes the current file. When the hash mark character "`#'" appears in a file name entered as part of an *ex* command argument, it is replaced by the alternate pathname. (The "`#'" character can be escaped by preceding it with a backslash.) * *buffer* One of a number of named areas for saving copies of text. Commands that change or delete text can save the changed or deleted text into a specific buffer, for later use, if the command allows it (i.e. the *ex* *change* command cannot save the changed text in a named buffer). Buffers are named with a single character, preceded by a double quote, e.g. `'"" in *vi* and without the double quote, e.g. `', in *ex* . (The double quote isn't necessary for *ex* because buffers names are denoted by their position in the command line.) Historic implementations of *ex*/*vi* limited `'to the alphanumeric characters; *nex*/*nvi* permits the use of any character without another meaning in the position where a buffer name is expected. Buffers named by uppercase characters are the same as buffers named by lowercase characters, e.g. the buffer named by the English character "`A'" is the same as the buffer named by the character "`a'", with the exception that, if the buffer contents are being changed (as with a text deletion or *vi* *change* command), the text is _appended_ to the buffer, instead of replacing the current contents. The buffers named by the numeric characters (in English, "`1'" through "`9'"), are special. If a region of text including characters from more than one line, or a single line of text specified by using a line-oriented motion, is changed or deleted in the file using the *vi* *change* or *delete* commands, a copy of the text is placed into the numeric buffer "`1'", regardless of the user specifying another buffer in which to save it. In addition, there are a few commands which, when used as a `motion'with the *vi* *change* and *delete* commands, _always_ copy the specified region of text into the numeric buffers regardless of the region including characters from more than one line. These commands are: ** *%* *(* *)* *`* */* *?* *N* *n* *{* *}* Before this copy is done, the previous contents of buffer "`1'" are moved into buffer "`2'", "`2'" into buffer "`3'", and so on. The contents of buffer "`9'" are discarded. In *vi* , text may be explicitly stored into the numeric buffers. In this case, the buffer rotation described above occurs before the replacement of the buffer's contents. The numeric buffers are only available in `visual'and `open'modes, and are not accessible by *ex* in any way, although changed and deleted text is still stored there while in *ex* mode. When a *vi* command synopsis shows both a `[buffer]'and a `[count]', they may be presented in any order. Finally, all buffers are either "line" or "character" oriented. All *ex* commands which store text into buffers are line oriented. Some *vi* commands which store text into buffers are line oriented, and some are character oriented; the description for each applicable *vi* command notes whether text copied into buffers using the command is line or character oriented. In addition, the *vi* command *display buffers* displays the current orientation for each buffer. Generally, the only importance attached to this orientation is that if the buffer is subsequently inserted into the text, line oriented buffers create new lines for each of the lines they contain, and character oriented buffers create new lines for any lines _other_ than the first and last lines they contain. The first and last lines are inserted into the text at the current cursor position, becoming part of the current line. If there is more than one line in the buffer, however, the current line itself will be split. * *unnamed buffer* The unnamed buffer is a text storage area which is used by commands that use or operate on a buffer when no buffer is specified by the user. If the command stores text into a buffer, the text is stored into the unnamed buffer even if a buffer is also specified by the user. It is not possible to append text to the unnamed buffer. If text is appended to a named buffer, the named buffer contains both the old and new text, while the unnamed buffer contains only the new text. There is no way to explicitly reference the unnamed buffer. Historically, the contents of the unnamed buffer were discarded by many different commands, even ones that didn't store text into it. *Nex*/*nvi* never discards the contents of the unnamed buffer until new text replaces them. * *whitespace* The characters and . * ** The character represented by an ASCII `'. This character is almost always treated identically to a `'character, but differs in that it can be escaped into the file text or into a command. * ** The character represented by an ASCII `'. This character is almost always treated identically to a `'character, but differs in that it cannot be escaped into the file text or into a command. 12 Vi Description ***************** *Vi* takes up the entire screen to display the edited file, except for the bottom line of the screen. The bottom line of the screen is used to enter *exp* commands, and for *vi* error and informational messages. If no other information is being displayed, the default display can show the current cursor row and cursor column, an indication of whether the file has been modified, and the current mode of the editor. See the `ruler' and `showmode' options for more information. Empty lines do not have any special representation on the screen, but lines on the screen that would logically come after the end of the file are displayed as a single tilde "`~'" character. To differentiate between empty lines and lines consisting of only whitespace characters, use the `list' option. Historically, implementations of *vi* have also displayed some lines as single asterisk "`@'" characters. These were lines that were not correctly displayed, i.e. lines on the screen that did not correspond to lines in the file, or lines that did not fit on the current screen. *Nvi* never displays lines in this fashion. *Vi* is a modeful editor, i.e. it has two modes, "command" mode and "text input" mode. When *vi* first starts, it is in command mode. There are several commands that change *vi* into text input mode. The `'character is used to resolve the text input into the file, and exit back into command mode. In *vi* command mode, the cursor is always positioned on the last column of characters which take up more than one column on the screen. In *vi* text insert mode, the cursor is positioned on the first column of characters which take up more than one column on the screen. When positioning the cursor to a new line and column, the type of movement is defined by the distance to the new cursor position. If the new position is close, the screen is scrolled to the new location. If the new position is far away, the screen is repainted so that the new position is on the screen. If the screen is scrolled, it is moved a minimal amount, and the cursor line will usually appear at the top or bottom of the screen. If the screen is repainted, the cursor line will appear in the center of the screen, unless the cursor is sufficiently close to the beginning or end of the file that this isn't possible. If the `leftright' option is set, the screen may be scrolled or repainted in a horizontal direction as well as in a vertical one. A major difference between the historical *vi* presentation and *nvi* is in the scrolling and screen oriented position commands, **, **, **, **, **, **, *H*, *L* and *M*. In historical implementations of *vi*, these commands acted on physical (as opposed to logical, or screen) lines. For lines that were sufficiently long in relation to the size of the screen, this meant that single line scroll commands might repaint the entire screen, scrolling or screen positioning commands might not change the screen or move the cursor at all, and some lines simply could not be displayed, even though *vi* would edit the file that contained them. In *nvi*, these commands act on logical, i.e. screen lines. You are unlikely to notice any difference unless you are editing files with lines significantly longer than a screen width. *Vi* keeps track of the currently "most attractive" cursor position. Each command description (for commands that alter the current cursor position), specifies if the cursor is set to a specific location in the line, or if it is moved to the "most attractive cursor position". The latter means that the cursor is moved to the cursor position that is horizontally as close as possible to the current cursor position. If the current line is shorter than the cursor position *vi* would select, the cursor is positioned on the last character in the line. (If the line is empty, the cursor is positioned on the first column of the line.) If a command moves the cursor to the most attractive position, it does not alter the current cursor position, and a subsequent movement will again attempt to move the cursor to that position. Therefore, although a movement to a line shorter than the currently most attractive position will cause the cursor to move to the end of that line, a subsequent movement to a longer line will cause the cursor to move back to the most attractive position. In addition, the *$* command makes the end of each line the most attractive cursor position rather than a specific column. Each *vi* command described below notes where the cursor ends up after it is executed. This position is described in terms of characters on the line, i.e. "the previous character", or, "the last character in the line". This is to avoid needing to continually refer to on what part of the character the cursor rests. The following words have special meaning for *vi* commands. * *previous context* The position of the cursor before the command which caused the last absolute movement was executed. Each *vi* command described in the next section that is considered an absolute movement is so noted. In addition, specifying _any_ address to an *ex* command is considered an absolute movement. * *motion* A second *vi* command can be used as an optional trailing argument to the *vi* *<*, *>*, *!*, *c*, *d*, *y*, and (depending on the `tildeop' option) *~* commands. This command indicates the end of the region of text that's affected by the command. The motion command may be either the command character repeated (in which case it means the current line) or a cursor movement command. In the latter case, the region affected by the command is from the starting or stopping cursor position which comes first in the file, to immediately before the starting or stopping cursor position which comes later in the file. Commands that operate on lines instead of using beginning and ending cursor positions operate on all of the lines that are wholly or partially in the region. In addition, some other commands become line oriented depending on where in the text they are used. The command descriptions below note these special cases. The following commands may all be used as motion components for *vi* commands: ** ** ** ** ** ** ** *$* *%* *'* *(* *)* *+* *,* *-* */* *0* *;* *?* *B* *E* *F* *G* *H* *L* *M* *N* *T* *W* *[[* *]]* *^* *_* *`* *b* *e* *f* *h* *j* *k* *l* *n* *t* *w* *{* *|* *}* The optional count prefix available for some of the *vi* commands that take motion commands, or the count prefix available for the *vi* commands that are used as motion components, may be included and is _always_ considered part of the motion argument. For example, the commands "`c2w'" and "`2cw'" are equivalent, and the region affected by the *c* command is two words of text. In addition, if the optional count prefix is specified for both the *vi* command and its motion component, the effect is multiplicative and is considered part of the motion argument. For example, the commands "`4cw'" and "`2c2w'" are equivalent, and the region affected by the *c* command is four words of text. * *count* A positive number used as an optional argument to most commands, either to give a size or a position (for display or movement commands), or as a repeat count (for commands that modify text). The count argument is always optional and defaults to 1 unless otherwise noted in the command description. When a *vi* command synopsis shows both a `[buffer]'and `[count]', they may be presented in any order. * *word* Generally, in languages where it is applicable, *vi* recognizes two kinds of words. First, a sequence of letters, digits and underscores, delimited at both ends by: characters other than letters, digits, or underscores, the beginning or end of a line, and the beginning or end of the file. Second, a sequence of characters other than letters, digits, underscores, or whitespace characters, delimited at both ends by: a letter, digit, underscore, or whitespace character, the beginning or end of a line, and the beginning or end of the file. For example, the characters "`!@#abc$%^ '" contain three words: "`!@#'", "`abc'" and "`$%^'". Groups of empty lines (or lines containing only whitespace characters) are treated as a single word. * *bigword* A set of non-whitespace characters preceded and followed by whitespace characters or the beginning or end of the file or line. For example, the characters "`!@#abc$%^ '" contain one bigword: "`!@#abc$%^'". Groups of empty lines (or lines containing only whitespace characters) are treated as a single bigword. * *paragraph* An area of text that begins with either the beginning of a file, an empty line, or a section boundary, and continues until either an empty line, section boundary, or the end of the file. Groups of empty lines (or lines containing only whitespace characters) are treated as a single paragraph. Additional paragraph boundaries can be defined using the `paragraphs' option. * *section* An area of text that starts with the beginning of the file or a line whose first character is an open brace "`{'" and continues until the next section or the end of the file. Additional section boundaries can be defined using the `sections' option. * *sentence* An area of text that begins with either the beginning of the file or the first nonblank character following the previous sentence, paragraph, or section boundary and continues until the end of the file or a period "`.'" exclamation point "`!'" or question mark "`?'" character, followed by either an end-of-line or two whitespace characters. Any number of closing parentheses "`)'", brackets "`]'", double-quote "`"'" or single quote "`''" characters can appear between the period, exclamation point, or question mark and the whitespace characters or end-of-line. Groups of empty lines (or lines containing only whitespace characters) are treated as a single sentence. 13 Vi Commands ************** The following section describes the commands available in the command mode of the *vi* editor. In each entry below, the tag line is a usage synopsis for the command character. In addition, the final line and column the cursor rests upon, and any options which affect the command are noted. -- Command: [count] Search forward `count'times for the current word. The current word begins at the first non-whitespace character on or after the current cursor position, and extends up to the next non-word character or the end of the line. The search is literal, i.e. no characters in the word have any special meaning in terms of Regular Expressions. It is an error if no matching pattern is found between the starting position and the end of the file. The ** command is an absolute movement. The ** command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Set to the line where the word is found. Column: Set to the first character of the word. Options: Affected by the `ignorecase' and `wrapscan' options. -- Command: [count] Page backward `count'screens. Two lines of overlap are maintained, if possible, by displaying the window starting at line `(top_line - count * window_size) + 2', where `window_size'is the value of the `window' option. (In the case of split screens, this size is corrected to the current screen size.) It is an error if the movement is past the beginning of the file. Line: Set to the last line of text displayed on the screen. Column: Set to the first nonblank character of the line. Options: Affected by the `window' option. -- Command: [count] Scroll forward `count'lines. If `count'is not specified, scroll forward the number of lines specified by the last ** or ** command. If this is the first ** or ** command, scroll forward half the number of lines in the screen. (In the case of split screens, the default scrolling distance is corrected to half the current screen size.) It is an error if the movement is past the end of the file. Line: Set to the current line plus the number of lines scrolled. Column: Set to the first nonblank character of the line. Options: None. -- Command: [count] Scroll forward `count'lines, leaving the cursor on the current line and column, if possible. It is an error if the movement is past the end of the file. Line: Unchanged unless the current line scrolls off the screen, in which case it is set to the first line on the screen. Column: Unchanged unless the current line scrolls off the screen, in which case it is set to the most attractive cursor position. Options: None. -- Command: [count] Page forward `count'screens. Two lines of overlap are maintained, if possible, by displaying the window starting at line `top_line + count * window_size - 2', where `window_size'is the value of the `window' option. (In the case of split screens, this size is corrected to the current screen size.) It is an error if the movement is past the end of the file. Line: Set to the first line on the screen. Column: Set to the first nonblank character of the current line. Options: Affected by the `window' option. -- Command: Display the file information. The information includes the current pathname, the current line, the number of total lines in the file, the current line as a percentage of the total lines in the file, if the file has been modified, was able to be locked, if the file's name has been changed, and if the edit session is read-only. Line: Unchanged. Column: Unchanged. Options: None. -- Command: [count] -- Command: [count] h Move the cursor back `count'characters in the current line. It is an error if the cursor is on the first character in the line. The ** and *h* commands may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the `current - count'character, or, the first character in the line if `count'is greater than or equal to the number of characters in the line before the cursor. Options: None. -- Command: [count] -- Command: [count] -- Command: [count] j Move the cursor down `count'lines without changing the current column. It is an error if the movement is past the end of the file. The **, ** and *j* commands may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to the current line plus `count'. Column: The most attractive cursor position. Options: None. -- Command: -- Command: Repaint the screen. Line: Unchanged. Column: Unchanged. Options: None. -- Command: [count] -- Command: [count] + Move the cursor down `count'lines to the first nonblank character of that line. It is an error if the movement is past the end of the file. The ** and *+* commands may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to the current line plus `count'. Column: Set to the first nonblank character in the line. Options: None. -- Command: [count] -- Command: [count] k Move the cursor up `count'lines, without changing the current column. It is an error if the movement is past the beginning of the file. The ** and *k* commands may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to the current line minus `count'. Column: The most attractive cursor position. Options: None. -- Command: Return to the most recent tag context. The ** command is an absolute movement. Line: Set to the context of the previous tag command. Column: Set to the context of the previous tag command. Options: None. -- Command: [count] Scroll backward `count'lines. If `count'is not specified, scroll backward the number of lines specified by the last ** or ** command. If this is the first ** or ** command, scroll backward half the number of lines in the screen. (In the case of split screens, the default scrolling distance is corrected to half the current screen size.) It is an error if the movement is past the beginning of the file. Line: Set to the current line minus the amount scrolled. Column: Set to the first nonblank character in the line. Options: None. -- Command: Switch to the next lower screen in the window, or, to the first screen if there are no lower screens in the window. Line: Set to the previous cursor position in the window. Column: Set to the previous cursor position in the window. Options: None. -- Command: [count] Scroll backward `count'lines, leaving the current line and column as is, if possible. It is an error if the movement is past the beginning of the file. Line: Unchanged unless the current line scrolls off the screen, in which case it is set to the last line of text displayed on the screen. Column: Unchanged unless the current line scrolls off the screen, in which case it is the most attractive cursor position. Options: None. -- Command: Suspend the current editor session. If the file has been modified since it was last completely written, and the `autowrite' option is set, the file is written before the editor session is suspended. If this write fails, the editor session is not suspended. Line: Unchanged. Column: Unchanged. Options: Affected by the `autowrite' option. -- Command: Execute *ex* commands or cancel partial commands. If an *ex* command is being entered (e.g. */*, *?*, *:* or *!*), the command is executed. If a partial command has been entered, e.g. "`[0-9]*'", or "`[0-9]*[!<>cdy]'", the command is cancelled. Otherwise, it is an error. Line: When an *ex* command is being executed, the current line is set as described for that command. Otherwise, unchanged. Column: When an *ex* command is being executed, the current column is set as described for that command. Otherwise, unchanged. Options: None. -- Command: Push a tag reference onto the tag stack. The tags files (see the `tags' option for more information) are searched for a tag matching the current word. The current word begins at the first non-whitespace character on or after the current cursor position, and extends up to the next non-word character or the end of the line. If a matching tag is found, the current file is discarded and the file containing the tag reference is edited. If the current file has been modified since it was last completely written, the command will fail. The ** command is an absolute movement. Line: Set to the line containing the matching tag string. Column: Set to the start of the matching tag string. Options: Affected by the `tags' and `taglength' options. -- Command: Switch to the most recently edited file. If the file has been modified since it was last completely written, and the `autowrite' option is set, the file is written out. If this write fails, the command will fail. Otherwise, if the current file has been modified since it was last completely written, the command will fail. Line: Set to the line the cursor was on when the file was last edited. Column: Set to the column the cursor was on when the file was last edited. Options: Affected by the `autowrite' option. -- Command: [count] -- Command: [count] l Move the cursor forward `count'characters without changing the current line. It is an error if the cursor is on the last character in the line. The ** and *l* commands may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. In addition, these commands may be used as the motion components of other commands when the cursor is on the last character in the line, without error. Line: Unchanged. Column: Set to the current character plus the next `count'characters, or to the last character on the line if `count'is greater than the number of characters in the line after the current character. Options: None. -- Command: [count] ! motion shell-argument(s) Replace text with results from a shell command. Pass the lines specified by the `count'and `motion'arguments as standard input to the program named by the `shell' option, and replace those lines with the output (both standard error and standard output) of that command. After the motion is entered, *vi* prompts for arguments to the shell command. Within those arguments, "`%'" and "`#'" characters are expanded to the current and alternate pathnames, respectively. The "`!'" character is expanded with the command text of the previous *!* or *:!* commands. (Therefore, the command *!!* repeats the previous *!* command.) The special meanings of "`%'", "`#'" and "`!'" can be overridden by escaping them with a backslash. If no *!* or *:!* command has yet been executed, it is an error to use an unescaped "`!'" character as a shell argument. The *!* command does _not_ do shell expansion on the strings provided as arguments. If any of the above expansions change the arguments the user entered, the command is redisplayed at the bottom of the screen. *Vi* then executes the program named by the `shell' option, with a *-c* flag followed by the arguments (which are bundled into a single argument). The *!* command is permitted in an empty file. If the file has been modified since it was last completely written, the *!* command will warn you. Line: The first line of the replaced text. Column: The first column of the replaced text. Options: Affected by the `shell' option. -- Command: [count] # #|+|- Increment or decrement the number referenced by the cursor. If the trailing character is a `+'or `#', the number is incremented by `count'. If the trailing character is a `-', the number is decremented by `count'. A leading "`0X'" or "`0x'" causes the number to be interpreted as a hexadecimal number. Otherwise, a leading "`0'" causes the number to be interpreted as an octal number, unless a non-octal digit is found as part of the number. Otherwise, the number is interpreted as a decimal number, and may have a leading `+'or `-'sign. The current number begins at the first non-blank character at or after the current cursor position, and extends up to the end of the line or the first character that isn't a possible character for the numeric type. The format of the number (e.g. leading 0's, signs) is retained unless the new value cannot be represented in the previous format. Octal and hexadecimal numbers, and the result of the operation, must fit into an "`unsigned long'". Similarly, decimal numbers and their result must fit into a "`signed long'". It is an error to use this command when the cursor is not positioned at a number. Line: Unchanged. Column: Set to the first character in the cursor number. Options: None. -- Command: [count] $ Move the cursor to the end of a line. If `count'is specified, the cursor moves down `count - 1'lines. It is not an error to use the *$* command when the cursor is on the last character in the line or when the line is empty. The *$* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the cursor is at, or before the first nonblank character in the line, in which case it is line oriented. It is not an error to use the *$* command as a motion component when the cursor is on the last character in the line, although it is an error when the line is empty. Line: Set to the current line plus `count'minus 1. Column: Set to the last character in the line. Options: None. -- Command: % Move to the matching character. The cursor moves to the parenthesis or curly brace which _matches_ the parenthesis or curly brace found at the current cursor position or which is the closest one to the right of the cursor on the line. It is an error to execute the *%* command on a line without a parenthesis or curly brace. Historically, any `count'specified to the *%* command was ignored. The *%* command is an absolute movement. The *%* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting point of the region is at or before the first nonblank character on its line, and the ending point is at or after the last nonblank character on its line, in which case it is line oriented. Line: Set to the line containing the matching character. Column: Set to the matching character. Options: None. -- Command: & Repeat the previous substitution command on the current line. Historically, any `count'specified to the *&* command was ignored. Line: Unchanged. Column: Unchanged if the cursor was on the last character in the line, otherwise, set to the first nonblank character in the line. Options: Affected by the `edcompatible', `extended', `ignorecase' and `magic' options. -- Command: ' -- Command: ` Return to a context marked by the character `'. If `'is the "`''" or "``'" character, return to the previous context. If `'is any other character, return to the context marked by that character (see the *m* command for more information). If the command is the *'* command, only the line value is restored, and the cursor is placed on the first nonblank character of that line. If the command is the *`* command, both the line and column values are restored. It is an error if the context no longer exists because of line deletion. (Contexts follow lines that are moved, or which are deleted and then restored.) The *'* and *`* commands are both absolute movements. They may be used as a motion component for other *vi* commands. For the *'* command, any text copied into a buffer is line oriented. For the *`* command, any text copied into a buffer is character oriented, unless it both starts and stops at the first character in the line, in which case it is line oriented. In addition, when using the *`* command as a motion component, commands which move backward and started at the first character in the line, or move forward and ended at the first character in the line, are corrected to the last character of the line preceding the starting and ending lines, respectively. Line: Set to the line from the context. Column: Set to the first nonblank character in the line, for the *'* command, and set to the context's column for the *`* command. Options: None. -- Command: [count] ( Back up `count'sentences. The *(* command is an absolute movement. The *(* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting and stopping points of the region are the first character in the line, in which case it is line oriented. If it is line oriented, the starting point of the region is adjusted to be the end of the line immediately before the starting cursor position. Line: Set to the line containing the beginning of the sentence. Column: Set to the first nonblank character of the sentence. Options: Affected by the `lisp' option. -- Command: [count] ) Move forward `count'sentences. The *)* command is an absolute movement. The *)* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting point of the region is the first character in the line, in which case it is line oriented. In the latter case, if the stopping point of the region is also the first character in the line, it is adjusted to be the end of the line immediately before it. Line: Set to the line containing the beginning of the sentence. Column: Set to the first nonblank character of the sentence. Options: Affected by the `lisp' option. -- Command: [count] , Reverse find character `count'times. Reverse the last *F*, *f*, *T* or *t* command, searching the other way in the line, `count'times. It is an error if a *F*, *f*, *T* or *t* command has not been performed yet. The *,* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the searched-for character for the *F* and *f* commands, before the character for the *t* command and after the character for the *T* command. Options: None. -- Command: [count] - Move to the first nonblank of the previous line, `count'times. It is an error if the movement is past the beginning of the file. The *-* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to the current line minus `count'. Column: Set to the first nonblank character in the line. Options: None. -- Command: [count] . Repeat the last *vi* command that modified text. The repeated command may be a command and motion component combination. If `count'is specified, it replaces _both_ the count specified for the repeated command, and, if applicable, for the repeated motion component. If `count'is not specified, the counts originally specified to the command being repeated are used again. As a special case, if the *.* command is executed immediately after the *u* command, the change log is rolled forward or backward, depending on the action of the *u* command. Line: Set as described for the repeated command. Column: Set as described for the repeated command. Options: None. -- Command: /RE -- Command: /RE/ [ -- Command: ?RE -- Command: ?RE? [ -- Command: N -- Command: n Search forward or backward for a regular expression. The commands beginning with a slash "`/'" character are forward searches, the commands beginning with a question mark "`?'" are backward searches. *Vi* prompts with the leading character on the last line of the screen for a string. It then searches forward or backward in the file for the next occurrence of the string, which is interpreted as a Basic Regular Expression. The */* and *?* commands are absolute movements. They may be used as the motion components of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the search started and ended on the first column of a line, in which case it is line oriented. In addition, forward searches ending at the first character of a line, and backward searches beginning at the first character in the line, are corrected to begin or end at the last character of the previous line. (Note, forward and backward searches can occur for both */* and *?* commands, if the `wrapscan' option is set.) If an offset from the matched line is specified (i.e. a trailing "`/'" or "`?'" character is followed by a signed offset), the buffer will always be line oriented (e.g. "`/string/+0'" will always guarantee a line orientation). The *N* command repeats the previous search, but in the reverse direction. The *n* command repeats the previous search. If either the *N* or *n* commands are used as motion components for the *!* command, you will not be prompted for the text of the bang command, instead the previous bang command will be executed. Missing RE's (e.g. "`//'", "`/'", "`??'", or "`?'" search for the last search RE, in the indicated direction. Searches may be interrupted using the `'character. Multiple search patterns may be grouped together by delimiting them with semicolons and zero or more whitespace characters, e.g. `/foo/ ; ?bar?'searches forward for `foo'and then, from that location, backwards for `bar'. When search patterns are grouped together in this manner, the search patterns are evaluated left to right with the final cursor position determined by the last search pattern. It is also permissible to append a *z* command to the search strings, e.g. `/foo/ z.'searches forward for the next occurrence of `foo', and then positions that line in the middle of screen. Line: Set to the line in which the match occurred. Column: Set to the first character of the matched string. Options: Affected by the `edcompatible', `extended', `ignorecase', `magic', and `wrapscan' options. -- Command: 0 Move to the first character in the current line. It is not an error to use the *0* command when the cursor is on the first character in the line, The *0* command may be used as the motion component of other *vi* commands, in which case it is an error if the cursor is on the first character in the line, and any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the first character in the line. Options: None. -- Command: : Execute an *ex* command. *Vi* prompts for an *ex* command on the last line of the screen, using a colon "`:'" character. The command is terminated by a `', `'or `'character; all of these characters may be escaped by using a `'character. The command is then executed. If the *ex* command writes to the screen, *vi* will prompt the user for a `'before continuing when the *ex* command finishes. Large amounts of output from the *ex* command will be paged for the user, and the user prompted for a `'or `'key to continue. In some cases, a quit (normally a "q" character) or `'may be entered to interrupt the *ex* command. When the *ex* command finishes, and the user is prompted to resume visual mode, it is also possible to enter another "`:'" character followed by another *ex* command. Line: The current line is set as described for the *ex* command. Column: The current column is set as described for the *ex* command. Options: Affected as described for the *ex* command. -- Command: [count] ; Repeat the last character find `count'times. The last character find is one of the *F*, *f*, *T* or *t* commands. It is an error if a *F*, *f*, *T* or *t* command has not been performed yet. The *;* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the searched-for character for the *F* and *f* commands, before the character for the *t* command and after the character for the *T* command. Options: None. -- Command: [count] < motion -- Command: [count] > motion Shift lines left or right. Shift the number of lines in the region specified by the `count'and `motion'left (for the *<* command) or right (for the *>* command) by the number of columns specified by the `shiftwidth' option. Only whitespace characters are deleted when shifting left. Once the first character in the line no longer contains a whitespace character, the command will succeed, but the line will not be modified. Line: Unchanged. Column: Set to the first nonblank character in the line. Options: Affected by the `shiftwidth' option. -- Command: @ buffer Execute a named buffer. Execute the named buffer as *vi* commands. The buffer may include *ex* commands, too, but they must be expressed as a *:* command. If the buffer is line oriented, `'characters are logically appended to each line of the buffer. If the buffer is character oriented, `'characters are logically appended to all but the last line in the buffer. If the buffer name is "`@'", or "`*'", then the last buffer executed shall be used. It is an error to specify "`@@'" or "`@*'" if there were no previous buffer executions. The text of a buffer may contain a *@* command, and it is possible to create infinite loops in this manner. (The `'character may be used to interrupt the loop.) Line: The current line is set as described for the command(s). Column: The current column is set as described for the command(s). Options: None. -- Command: [count] A Enter input mode, appending the text after the end of the line. If `count'is specified, the text is repeatedly input `count - 1'more times after input mode is exited. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [count] B Move backward `count'bigwords. Move the cursor backward to the beginning of a bigword by repeating the following algorithm: if the current position is at the beginning of a bigword or the character at the current position cannot be part of a bigword, move to the first character of the preceding bigword. Otherwise, move to the first character of the bigword at the current position. If no preceding bigword exists on the current line, move to the first character of the last bigword on the first preceding line that contains a bigword. The *B* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Set to the line containing the word selected. Column: Set to the first character of the word selected. Options: None. -- Command: [buffer] [count] C Change text from the current position to the end-of-line. If `count'is specified, the input text replaces from the current position to the end-of-line, plus `count - 1'subsequent lines. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [buffer] D Delete text from the current position to the end-of-line. It is not an error to execute the *D* command on an empty line. Line: Unchanged. Column: Set to the character before the current character, or, column 1 if the cursor was on column 1. Options: None. -- Command: [count] E Move forward `count'end-of-bigwords. Move the cursor forward to the end of a bigword by repeating the following algorithm: if the current position is the end of a bigword or the character at that position cannot be part of a bigword, move to the last character of the following bigword. Otherwise, move to the last character of the bigword at the current position. If no succeeding bigword exists on the current line, move to the last character of the first bigword on the next following line that contains a bigword. The *E* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Set to the line containing the word selected. Column: Set to the last character of the word selected. Options: None. -- Command: [count] F Search `count'times backward through the current line for `'.

Column: Set to the searched-for character. Options: None. -- Command: [count] G Move to line `count', or the last line of the file if `count'not specified. The *G* command is an absolute movement. The *G* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to `count', if specified, otherwise, the last line. Column: Set to the first nonblank character in the line. Options: None. -- Command: [count] H Move to the screen line `count - 1'lines below the top of the screen. The *H* command is an absolute movement. The *H* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to the line `count - 1'lines below the top of the screen. Column: Set to the first nonblank character of the _screen_ line. Options: None. -- Command: [count] I Enter input mode, inserting the text at the beginning of the line. If `count'is specified, the text input is repeatedly input `count - 1'more times. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: None. -- Command: [count] J Join lines. If `count'is specified, `count'lines are joined; a minimum of two lines are always joined, regardless of the value of `count'. If the current line ends with a whitespace character, all whitespace is stripped from the next line. Otherwise, if the next line starts with a open parenthesis "`('" do nothing. Otherwise, if the current line ends with a question mark "`?'", period "`.'" or exclamation point "`!'", insert two spaces. Otherwise, insert a single space. It is not an error to join lines past the end of the file, i.e. lines that do not exist. Line: Unchanged. Column: Set to the character after the last character of the next-to-last joined line. Options: None. -- Command: [count] L Move to the screen line `count - 1'lines above the bottom of the screen. The *L* command is an absolute movement. The *L* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Line: Set to the line `count - 1'lines above the bottom of the screen. Column: Set to the first nonblank character of the _screen_ line. Options: None. -- Command: M Move to the screen line in the middle of the screen. The *M* command is an absolute movement. The *M* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. Historically, any `count'specified to the *M* command was ignored. Line: Set to the line in the middle of the screen. Column: Set to the first nonblank character of the _screen_ line. Options: None. -- Command: [count] O Enter input mode, appending text in a new line above the current line. If `count'is specified, the text input is repeatedly input `count - 1'more times. Historically, any `count'specified to the *O* command was ignored. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [buffer] P Insert text from a buffer. Text from the buffer (the unnamed buffer by default) is inserted before the current column or, if the buffer is line oriented, before the current line. Line: Set to the lowest numbered line insert, if the buffer is line oriented, otherwise unchanged. Column: Set to the first nonblank character of the appended text, if the buffer is line oriented, otherwise, the last character of the appended text. Options: None. -- Command: Q Exit *vi* (or visual) mode and switch to *ex* mode. Line: Unchanged. Column: No longer relevant. Options: None. -- Command: [count] R Enter input mode, replacing the characters in the current line. If `count'is specified, the text input is repeatedly input `count - 1'more times. If the end of the current line is reached, no more characters are replaced and any further characters input are appended to the line. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [buffer] [count] S Substitute `count'lines. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [count] T Search backward, `count'times, through the current line for the character _after_ the specified `'. The *T* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the character _after_ the searched-for character. Options: None. -- Command: U Restore the current line to its state before the cursor last moved to it. Line: Unchanged. Column: The first character in the line. Options: None. -- Command: [count] W Move forward `count'bigwords. Move the cursor forward to the beginning of a bigword by repeating the following algorithm: if the current position is within a bigword or the character at that position cannot be part of a bigword, move to the first character of the next bigword. If no subsequent bigword exists on the current line, move to the first character of the first bigword on the first following line that contains a bigword. The *W* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: The line containing the word selected. Column: The first character of the word selected. Options: None. -- Command: [buffer] [count] X Delete `count'characters before the cursor. If the number of characters to be deleted is greater than or equal to the number of characters to the beginning of the line, all of the characters before the current cursor position, to the beginning of the line, are deleted. Line: Unchanged. Column: Set to the current character minus `count', or the first character if count is greater than the number of characters in the line before the cursor. Options: None. -- Command: [buffer] [count] Y Copy (or "yank") `count'lines into the specified buffer. Line: Unchanged. Column: Unchanged. Options: None. -- Command: ZZ Write the file and exit *vi*. The file is only written if it has been modified since the last complete write of the file to any file. The *ZZ* command will exit the editor after writing the file, if there are no further files to edit. Entering two "quit" commands (i.e. *wq*, *quit*, *xit* or *ZZ*) in a row will override this check and the editor will exit, ignoring any files that have not yet been edited. Line: Unchanged. Column: Unchanged. Options: None. -- Command: [count] [[ Back up `count'section boundaries. The *[[* command is an absolute movement. The *[[* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting position is column 0, in which case it is line oriented. It is an error if the movement is past the beginning of the file. Line: Set to the previous line that is `count'section boundaries back, or the first line of the file if no more section boundaries exist preceding the current line. Column: Set to the first nonblank character in the line. Options: Affected by the `sections' option. -- Command: [count] ]] Move forward `count'section boundaries. The *]]* command is an absolute movement. The *]]* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting position is column 0, in which case it is line oriented. It is an error if the movement is past the end of the file. Line: Set to the line that is `count'section boundaries forward, or to the last line of the file if no more section boundaries exist following the current line. Column: Set to the first nonblank character in the line. Options: Affected by the `sections' option. -- Command: ^ Move to first nonblank character on the current line. The *^* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the first nonblank character of the current line. Options: None. -- Command: [count] _ Move down `count - 1'lines, to the first nonblank character. The *_* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is line oriented. It is not an error to execute the *_* command when the cursor is on the first character in the line. Line: The current line plus `count - 1'. Column: The first nonblank character in the line. Options: None. -- Command: [count] a Enter input mode, appending the text after the cursor. If `count'is specified, the text input is repeatedly input `count - 1'more times. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [count] b Move backward `count'words. Move the cursor backward to the beginning of a word by repeating the following algorithm: if the current position is at the beginning of a word, move to the first character of the preceding word. Otherwise, the current position moves to the first character of the word at the current position. If no preceding word exists on the current line, move to the first character of the last word on the first preceding line that contains a word. The *b* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Set to the line containing the word selected. Column: Set to the first character of the word selected. Options: None. -- Command: [buffer] [count] c motion Change the region of text specified by the `count'and `motion'. If only part of a single line is affected, then the last character being changed is marked with a "`$'". Otherwise, the region of text is deleted, and input mode is entered. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [buffer] [count] d motion Delete the region of text specified by the `count'and `motion'. Line: Set to the line where the region starts. Column: Set to the first character in the line after the last character in the region. If no such character exists, set to the last character before the region. Options: None. -- Command: [count] e Move forward `count'end-of-words. Move the cursor forward to the end of a word by repeating the following algorithm: if the current position is the end of a word, move to the last character of the following word. Otherwise, move to the last character of the word at the current position. If no succeeding word exists on the current line, move to the last character of the first word on the next following line that contains a word. The *e* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Set to the line containing the word selected. Column: Set to the last character of the word selected. Options: None. -- Command: [count] f Search forward, `count'times, through the rest of the current line for `'. The *f* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the searched-for character. Options: None. -- Command: [count] i Enter input mode, inserting the text before the cursor. If `count'is specified, the text input is repeatedly input `count - 1'more times. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: m Save the current context (line and column) as `'. The exact position is referred to by "``'". The line is referred to by "`''". Historically, `'was restricted to lower-case letters. *Nvi* permits the use of any character. Line: Unchanged. Column: Unchanged. Options: None. -- Command: [count] o Enter input mode, appending text in a new line under the current line. If `count'is specified, the text input is repeatedly input `count - 1'more times. Historically, any `count'specified to the *o* command was ignored. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [buffer] p Append text from a buffer. Text from the buffer (the unnamed buffer by default) is appended after the current column or, if the buffer is line oriented, after the current line. Line: Set to the first line appended, if the buffer is line oriented, otherwise unchanged. Column: Set to the first nonblank character of the appended text if the buffer is line oriented, otherwise, the last character of the appended text. Options: None. -- Command: [count] r Replace characters. The next `count'characters in the line are replaced with `'. Replacing characters with `'characters results in creating new, empty lines into the file. If `'is `', the command is cancelled. Line: Unchanged unless the replacement character is a `', in which case it is set to the current line plus `count - 1'. Column: Set to the last character replaced, unless the replacement character is a `', in which case the cursor is in column 1 of the last line inserted. Options: None. -- Command: [buffer] [count] s Substitute `count'characters in the current line starting with the current character. Line: Set to the last line upon which characters were entered. Column: Set to the last character entered. Options: Affected by the `altwerase', `autoindent', `beautify', `showmatch', `ttywerase' and `wrapmargin' options. -- Command: [count] t Search forward, `count'times, through the current line for the character immediately _before_ `'. The *t* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Unchanged. Column: Set to the character _before_ the searched-for character. Options: None. -- Command: u Undo the last change made to the file. If repeated, the *u* command alternates between these two states, and is its own inverse. When used after an insert that inserted text on more than one line, the lines are saved in the numeric buffers. The *.* command, when used immediately after the *u* command, causes the change log to be rolled forward or backward, depending on the action of the *u* command. Line: Set to the position of the first line changed, if the reversal affects only one line or represents an addition or change; otherwise, the line preceding the deleted text. Column: Set to the cursor position before the change was made. Options: None. -- Command: [count] w Move forward `count'words. Move the cursor forward to the beginning of a word by repeating the following algorithm: if the current position is at the beginning of a word, move to the first character of the next word. If no subsequent word exists on the current line, move to the first character of the first word on the first following line that contains a word. The *w* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. Line: Set to the line containing the word selected. Column: Set to the first character of the word selected. Options: None. -- Command: [buffer] [count] x Delete `count'characters. The deletion is at the current character position. If the number of characters to be deleted is greater than or equal to the number of characters to the end of the line, all of the characters from the current cursor position to the end of the line are deleted. Line: Unchanged. Column: Unchanged unless the last character in the line is deleted and the cursor is not already on the first character in the line, in which case it is set to the previous character. Options: None. -- Command: [buffer] [count] y motion Copy (or "yank") the text region specified by the `count'and `motion', into a buffer. Line: Unchanged, unless the region covers more than a single line, in which case it is set to the line where the region starts. Column: Unchanged, unless the region covers more than a single line, in which case it is set to the character were the region starts. Options: None. -- Command: [count1] z [ Redraw the screen with a window `count2'lines long, with line `count1'placed as specified by the `type'character. If `count1'is not specified, it defaults to the current line. If `count2'is not specified, it defaults to the current window size. The following `type'characters may be used: + If `count1'is specified, place the line `count1'at the top of the screen. Otherwise, display the screen after the current screen, similarly to the ** command. Place the line `count1'at the top of the screen. . Place the line `count1'in the center of the screen. - Place the line `count1'at the bottom of the screen. ^ If `count1'is specified, place the line that is at the top of the screen when `count1'is at the bottom of the screen, at the bottom of the screen, i.e. display the screen before the screen before `count1'. Otherwise, display the screen before the current screen, similarly to the ** command. Line: Set to `count1'unless `count1'is not specified and the `type'character was either "`^'" or "`+'", in which case it is set to the line before the first line on the previous screen or the line after the last line on the previous screen, respectively. Column: Set to the first nonblank character in the line. Options: None. -- Command: [count] { Move backward `count'paragraphs. The *{* command is an absolute movement. The *{* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting character is the first character on its line, in which case it is line oriented. Line: Set to the line containing the beginning of the previous paragraph. Column: Set to the first nonblank character in the line. Options: Affected by the `paragraph' option. -- Command: [count] | Move to a specific _column_ position on the current line. The *|* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented. It is an error to use the *|* command as a motion component and for the cursor not to move. Line: Unchanged. Column: Set to the character occupying the column position identified by `count', if the position exists in the line. If the column length of the current line is less than `count', the cursor is moved to the last character in the line. Options: None. -- Command: [count] } Move forward `count'paragraphs. The *}* command is an absolute movement. The *}* command may be used as the motion component of other *vi* commands, in which case any text copied into a buffer is character oriented, unless the starting character is at or before any nonblank characters in its line, in which case it is line oriented. Line: Set to the line containing the beginning of the next paragraph. Column: Set to the first nonblank character in the line. Options: Affected by the `paragraph' option. -- Command: [count] ~ Reverse the case of the next `count'character(s). This is the historic semantic for the *~* command and it is only in effect if the `tildeop' option is not set. Lowercase alphabetic characters are changed to uppercase, and uppercase characters are changed to lowercase. No other characters are affected. Historically, the *~* command did not take an associated count, nor did it move past the end of the current line. As it had no associated motion it was difficult to change the case of large blocks of text. In *nvi*, if the cursor is on the last character of a line, and there are more lines in the file, the cursor moves to the next line. It is not an error to specify a count larger than the number of characters between the cursor and the end of the file. Line: Set to the line of the character after `count'characters, or, end of file. Column: Set to the character after `count'characters, or, end-of-file. Options: Affected by the `tildeop' option. -- Command: [count] ~ motion Reverse the case of the characters in a text region specified by the `count'and `motion'. Only in effect if the `tildeop' option is set. Lowercase characters are changed to uppercase, and uppercase characters are changed to lowercase. No other characters are affected. Line: Set to the line of the character after the last character in the region. Column: Set to the character after the last character in the region. Options: Affected by the `tildeop' option. -- Command: Interrupt the current operation. Many of the potentially long-running *vi* commands may be interrupted using the terminal interrupt character. These operations include searches, file reading and writing, filter operations and map character expansion. Interrupts are also enabled when running commands outside of *vi*. If the `'character is used to interrupt while entering an *ex* command, the command is aborted, the cursor returns to its previous position, and *vi* remains in command mode. Generally, if the `'character is used to interrupt any operation, any changes made before the interrupt are left in place. Line: Dependent on the operation being interrupted. Column: Dependent on the operation being interrupted. Options: None. 14 Vi Text Input Commands ************************* The following section describes the commands available in the text input mode of the *vi* editor. Historically, *vi* implementations only permitted the characters inserted on the current line to be erased. In addition, only the `'erase character and the "`0'" and "`^'" erase strings could erase autoindent characters. (Autoindent characters include both the characters inserted automatically at the beginning of an input line as well as characters inserted using the `'command.) This implementation permits erasure to continue past the beginning of the current line, and back to where text input mode was entered. In addition, autoindent characters may be erased using the standard erase characters. For the line and word erase characters, reaching the autoindent characters forms a "soft" boundary, denoting the end of the current word or line erase. Repeating the word or line erase key will erase the autoindent characters. Historically, *vi* always used `'and `'as character and word erase characters, respectively, regardless of the current terminal settings. This implementation accepts, in addition to these two characters, the current terminal characters for those operations. -- Input: If the first character of the input is a `', the previous input is replayed, as if just entered. -- Input: If the previous character on the line was an autoindent character, erase characters to move the cursor back to the column immediately after the previous (1-based) column which is a multiple of the `shiftwidth' edit option. This may result in any number of `'and `'characters preceding the cursor being changed. Otherwise, if the `autoindent' option is set and the user is entering the first character in the line, `'is ignored. Otherwise, a literal `'character is entered. -- Input: ^ If the previous character on the line was an autoindent character, erase all of the autoindent characters on the line. In addition, the autoindent level is reset to 0. -- Input: 0 If the previous character on the line was an autoindent character, erase all of the autoindent characters on the line. The autoindent level is not altered. -- Input: Insert sufficient `'and `'characters to move the cursor forward to the column immediately after the next (1-based) column which is a multiple of the `shiftwidth' edit option. This may result in any number of `'and `'characters preceding the cursor being changed. Historically, *vi* did not permit the `'command to be used unless the cursor was at the first column of a new line or it was preceded only by autoindent characters. *Nvi* permits it to be used at any time during insert mode. -- Input: -- Input: Erase the last character. -- Input: Quote the next character. The next character will not be mapped (see the *map* command for more information) or interpreted specially. A carat "`^'" character will be displayed immediately as a placeholder, but will be replaced by the next character. -- Input: If on the colon command line, and the `filec' edit option is set, behave as described for that option. Otherwise, if on the colon command line, execute the command. Otherwise, if not on the colon command line, resolve all text input into the file, and return to command mode. -- Input: Erase the current line. -- Input: -- Input: Erase the last word. The definition of word is dependent on the `altwerase' and `ttywerase' options. -- Input: [0-9A-Fa-f]+ Insert a character with the specified hexadecimal value into the text. The value is delimited by any non-hexadecimal character or the input of the maximum number of characters that can be translated into a single character value. -- Input: Interrupt text input mode, returning to command mode. If the `'character is used to interrupt inserting text into the file, it is as if the `'character was used; all text input up to the interruption is resolved into the file. 15 Ex Addressing **************** Addressing in *ex* (and when *ex* commands are executed from *vi* ) relates to the current line. In general, the current line is the last line affected by a command. The exact effect on the current line is discussed under the description of each command. When the file contains no lines, the current line is zero. Addresses are constructed by one or more of the following methods: 1. The address "`.'" refers to the current line. 2. The address "`$'" refers to the last line of the file. 3. The address "`N'", where `N'is a positive number, refers to the N-th line of the file. 4. The address "`''" or "``'" refers to the line marked with the name `'. (See the *k* or *m* commands for more information on how to mark lines.) 5. A regular expression (RE) enclosed by slashes "`/'" is an address, and it refers to the first line found by searching forward from the line _after_ the current line toward the end of the file, and stopping at the first line containing a string matching the RE. (The trailing slash can be omitted at the end of the command line.) If no RE is specified, i.e. the pattern is "`//'", the last RE used in any command is used in the search. If the `extended' option is set, the RE is handled as an extended RE, not a basic RE. If the `wrapscan' option is set, the search wraps around to the beginning of the file and continues up to and including the current line, so that the entire file is searched. The form "`e/'" is accepted for historic reasons, and is identical to "`//'". 6. An RE enclosed in question marks "`?'" addresses the first line found by searching backward from the line _preceding_ the current line, toward the beginning of the file and stopping at the first line containing a string matching the RE. (The trailing question mark can be omitted at the end of a command line.) If no RE is specified, i.e. the pattern is "`??'", the last RE used in any command is used in the search. If the `extended' option is set, the RE is handled as an extended RE, not a basic RE. If the `wrapscan' option is set, the search wraps around from the beginning of the file to the end of the file and continues up to and including the current line, so that the entire file is searched. The form "`e?'" is accepted for historic reasons, and is identical to "`??'". 7. An address followed by a plus sign "`+'" or a minus sign "`-'" followed by a number is an offset address and refers to the address plus (or minus) the indicated number of lines. If the address is omitted, the addition or subtraction is done with respect to the current line. 8. An address of "`+'" or "`-'" followed by a number is an offset from the current line. For example, "`-5'" is the same as "`.-5'". 9. An address ending with "`+'" or "`-'" has 1 added to or subtracted from the address, respectively. As a consequence of this rule and of the previous rule, the address "`-'" refers to the line preceding the current line. Moreover, trailing "`+'" and "`-'" characters have a cumulative effect. For example, "`++-++'" refers to the current line plus 3. 10. A percent sign "`%'" is equivalent to the address range "`1,$'". *Ex* commands require zero, one, or two addresses. It is an error to specify an address to a command which requires zero addresses. If the user provides more than the expected number of addresses to any *ex* command, the first addresses specified are discarded. For example, "`1,2,3,5'"print prints lines 3 through 5, because the *print* command only takes two addresses. The addresses in a range are separated from each other by a comma "`,'" or a semicolon "`;'". In the latter case, the current line "`.'" is set to the first address, and only then is the second address calculated. This feature can be used to determine the starting line for forward and backward searches (see rules (5) and (6) above). The second address of any two-address sequence corresponds to a line that follows, in the file, the line corresponding to the first address. The first address must be less than or equal to the second address. The first address must be greater than or equal to the first line of the file, and the last address must be less than or equal to the last line of the file. 16 Ex Description ***************** The following words have special meanings for *ex* commands. * ** The end-of-file character is used to scroll the screen in the *ex* editor. This character is normally `'. However, whatever character is set for the current terminal is supported as well as `'. * *line* A single-line address, given in any of the forms described in the section entitled "*Ex Addressing*" . The default for `line'is the current line. * *range* A line, or a pair of line addresses, separated by a comma or semicolon. (See the section entitled "*Ex Addressing*" for more information.) The default for range is the current line _only_, i.e. "`.,.'". A percent sign "`%'" stands for the range "`1,$'". The starting address must be less than, or equal to, the ending address. * *count* A positive integer, specifying the number of lines to be affected by the command; the default is 1. Generally, a count past the end-of-file may be specified, e.g. the command "`p 3000'" in a 10 line file is acceptable, and will print from the current line through the last line in the file. * *flags* One or more of the characters "#", "p", and "l". When a command that accepts these flags completes, the addressed line(s) are written out as if by the corresponding *#*, *l* or *p* commands. In addition, any number of "`+'" or "`-'" characters can be specified before, after, or during the flags, in which case the line written is not necessarily the one affected by the command, but rather the line addressed by the offset address specified. The default for `flags'is none. * *file* A pattern used to derive a pathname; the default is the current file. File names are subjected to normal `sh'(1) word expansions. Anywhere a file name is specified, it is also possible to use the special string "`/tmp'". This will be replaced with a temporary file name which can be used for temporary work, e.g. "`:e /tmp'" creates and edits a new file. If both a count and a range are specified for commands that use either, the starting line for the command is the _last_ line addressed by the range, and `count'- 1 subsequent lines are affected by the command, e.g. the command "`2,3p4'" prints out lines 3, 4, 5 and 6. When only a line or range is specified, with no command, the implied command is either a *list*, *number* or *print* command. The command used is the most recent of the three commands to have been used (including any use as a flag). If none of these commands have been used before, the *print* command is the implied command. When no range or count is specified and the command line is a blank line, the current line is incremented by 1 and then the current line is displayed. Zero or more whitespace characters may precede or follow the addresses, count, flags, or command name. Any object following a command name (such as buffer, file, etc.), that begins with an alphabetic character, should be separated from the command name by at least one whitespace character. Any character, including `', "`%'" and "`#'" retain their literal value when preceded by a backslash. 17 Ex Commands ************** The following section describes the commands available in the *ex* editor. In each entry below, the tag line is a usage synopsis for the command. Each command can be entered as the abbreviation (those characters in the synopsis command word preceding the "[" character), the full command (all characters shown for the command word, omitting the "[" and "]" characters), or any leading subset of the full command down to the abbreviation. For example, the args command (shown as "`ar[gs]'" in the synopsis) can be entered as "`ar'", "`arg'" or "`args'". Each *ex* command described below notes the new current line after it is executed, as well as any options that affect the command. -- Command: " A comment. Command lines beginning with the double-quote character "`"'" are ignored. This permits comments in editor scripts and startup files. -- Command: -- Command: Scroll the screen. Write the next N lines, where N is the value of the `scroll' option. The command is the end-of-file terminal character, which may be different on different terminals. Traditionally, it is the `'key. Historically, the *eof* command ignored any preceding count, and the `'character was ignored unless it was entered as the first character of the command. This implementation treats it as a command _only_ if entered as the first character of the command line, and otherwise treats it as any other character. Line: Set to the last line written. Options: Affected by the `scroll' option. -- Command: ! argument(s) -- Command: [range]! argument(s) Execute a shell command, or filter lines through a shell command. In the first synopsis, the remainder of the line after the "`!'" character is passed to the program named by the `shell' option, as a single argument. Within the rest of the line, "`%'" and "`#'" are expanded into the current and alternate pathnames, respectively. The character "`!'" is expanded with the command text of the previous *!* command. (Therefore, the command *!!* repeats the previous *!* command.) The special meanings of "`%'", "`#'", and "`!'" can be overridden by escaping them with a backslash. If no *!* or *:!* command has yet been executed, it is an error to use an unescaped "`!'" character. The *!* command does _not_ do shell expansion on the strings provided as arguments. If any of the above expansions change the command the user entered, the command is redisplayed at the bottom of the screen. *Ex* then executes the program named by the `shell' option, with a *-c* flag followed by the arguments (which are bundled into a single argument). The *!* command is permitted in an empty file. If the file has been modified since it was last completely written, the *!* command will warn you. A single "`!'" character is displayed when the command completes. In the second form of the *!* command, the remainder of the line after the "`!'" is passed to the program named by the `shell' option, as described above. The specified lines are passed to the program as standard input, and the standard and standard error output of the program replace the original lines. Line: Unchanged if no range was specified, otherwise set to the first line of the range. Options: Affected by the `shell' and `warn' options. -- Command: [range] # [ -- Command: [range] nu[mber] [ Display the selected lines, each preceded with its line number. The line number format is "%6d", followed by two spaces. Line: Set to the last line displayed. Options: Affected by the `list' option. -- Command: @ buffer -- Command: * buffer Execute a buffer. Each line in the named buffer is executed as an *ex* command. If no buffer is specified, or if the specified buffer is "`@'" or "`*'", the last buffer executed is used. -- Command: [range] <[< ...] [ Shift lines left or right. The specified lines are shifted to the left (for the *<* command) or right (for the *>* command), by the number of columns specified by the `shiftwidth' option. Only leading whitespace characters are deleted when shifting left; once the first column of the line contains a nonblank character, the *shift* command will succeed, but the line will not be modified. If the command character *<* or *>* is repeated more than once, the command is repeated once for each additional command character. Line: If the current line is set to one of the lines that are affected by the command, it is unchanged. Otherwise, it is set to the first nonblank character of the lowest numbered line shifted. Options: Affected by the `shiftwidth' option. -- Command: [line] = [ Display the line number of `line'(which defaults to the last line in the file). Line: Unchanged. Options: None. -- Command: [range] >[> ...] [ Shift right. The specified lines are shifted to the right by the number of columns specified by the `shiftwidth' option, by inserting tab and space characters. Empty lines are not changed. If the command character "`>'" is repeated more than once, the command is repeated once for each additional command character. Line: Set to the last line modified by the command. Options: Affected by the `shiftwidth' option. -- Command: ab[brev] lhs rhs Add an abbreviation to the current abbreviation list. When inserting text in *vi*, each time a non-word character is entered after a word character, a set of characters ending at the word character are checked for a match with `lhs'. If a match is found, they are replaced with `rhs'. The set of characters that are checked for a match are defined as follows, for inexplicable historical reasons. If only one or two characters were entered before the non-word character that triggered the check, and after the beginning of the insertion, or the beginning of the line or the file, or the last `'character that was entered, then the one or the both characters are checked for a match. Otherwise, the set includes both characters, as well as the characters that precede them that are the same word class (i.e. word or non-word) as the *second* to last character entered before the non-word character that triggered the check, back to the first `'character, the beginning of the insertion, or the beginning of the line or the file. For example, the abbreviations: :abbreviate abc ABC :abbreviate #i #include :abbreviate /*#i /*#include will all work, while the abbreviations: :abbreviate a#i A#include :abbreviate /* /******************** will not work, and are not permitted by *nvi*. To keep the abbreviation expansion from happening, the character immediately following the `lhs'characters should be quoted with a `'character. The replacement `rhs'is itself subject to both further abbreviation expansion and further map expansion. Line: Unchanged. Options: None. -- Command: [line] a[ppend][!] The input text is appended to the specified line. If line 0 is specified, the text is inserted at the beginning of the file. Set to the last line input. If no lines are input, then set to `line', or to the first line of the file if a `line'of 0 was specified. Following the command name with a "`!'" character causes the `autoindent' option to be toggled for the duration of the command. Line: Unchanged. Options: Affected by the `autoindent' and `number' options. -- Command: ar[gs] Display the argument list. The current argument is displayed inside of "`['" and "`]'" characters. The argument list is the list of operands specified on startup, which can be replaced using the *next* command. Line: Unchanged. Options: None. -- Command: bg *Vi* mode only. Background the current screen. The screen is unchanged, but is no longer accessible and disappears from the display. Use the *fg* command to bring the screen back to the display foreground. Line: Set to the current line when the screen was last edited. Options: None. -- Command: [range] c[hange][!] [ Replace the lines with input text. Following the command name with a "`!'" character causes the `autoindent' option to be toggled for the duration of the command. Line: Set to the last line input, or, if no lines were input, set to the line before the target line, or to the first line of the file if there are no lines preceding the target line. Options: Affected by the `autoindent' and `number' options. -- Command: chd[ir][!] [ -- Command: cd[!] [ Change the current working directory. The `directory'argument is subjected to `sh'(1) word expansions. When invoked with no directory argument and the `HOME'environment variable is set, the directory named by the `HOME'environment variable becomes the new current directory. Otherwise, the new current directory becomes the directory returned by the `getpwent'(3) routine. The *chdir* command will fail if the file has been modified since the last complete write of the file. You can override this check by appending a "`!'" character to the command. Line: Unchanged. Options: Affected by the `cdpath' option. -- Command: [range] co[py] line [flags] -- Command: [range] t line [flags] Copy the specified lines (range) after the destination line. Line 0 may be specified to insert the lines at the beginning of the file. Line: Unchanged. Options: None. -- Command: cs[cope] command [args] Execute a *cscope* command. For more information, see the section of the reference manual entitled "*Tags, Tag Stacks, and Cscope*" . -- Command: [range] d[elete] [ Delete the lines from the file. The deleted text is saved in the specified buffer, or, if no buffer is specified, in the unnamed buffer. If the command name is followed by a letter that could be interpreted as either a buffer name or a flag value (because neither a `count'or `flags'values were given), *ex* treats the letter as a `flags'value if the letter immediately follows the command name, without any whitespace separation. If the letter is preceded by whitespace characters, it treats it as a buffer name. Line: Set to the line following the deleted lines, or to the last line if the deleted lines were at the end. Options: None. -- Command: di[splay] b[uffers] | c[onnections] | s[creens] | t[ags] Display buffers, *cscope* connections, screens or tags. The *display* command takes one of three additional arguments, which are as follows: b[uffers] Display all buffers (including named, unnamed, and numeric) that contain text. c[onnections] Display the source directories for all attached *cscope* databases. s[creens] Display the file names of all background screens. t[ags] Display the tags stack. Line: Unchanged. Options: None. -- Command: e[dit][!] [ -- Command: ex[!] [ -- Command: vs[plit][!] [ Edit a different file. If the current buffer has been modified since the last complete write, the command will fail. You can override this by appending a "`!'" character to the command name. If the "`+cmd'" option is specified, that *ex* command will be executed in the new file. Any *ex* command may be used, although the most common use of this feature is to specify a line number or search pattern to set the initial location in the new file. Capitalizing the first letter of the command, i.e., *Edit* or *Ex*, while in *vi* mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. *vsplit* is similar, but the screen will be split vertically to produce the new screen, rather than horizontally. Line: If you have previously edited the file, the current line will be set to your last position in the file. If that position does not exist, or you have not previously edited the file, the current line will be set to the first line of the file if you are in *vi* mode, and the last line of the file if you are in *ex*. Options: None. -- Command: exu[sage] [ Display usage for an *ex* command. If `command'is specified, a usage statement for that command is displayed. Otherwise, usage statements for all *ex* commands are displayed. Line: Unchanged. Options: None. -- Command: f[ile] [ Display and optionally change the file name. If a file name is specified, the current pathname is changed to the specified name. The current pathname, the number of lines, and the current position in the file are displayed. Line: Unchanged. Options: None. -- Command: fg [ *Vi* mode only. Foreground the specified screen. If the argument name doesn't exactly match the name of a file displayed by a background screen, it is compared against the last component of each of the file names. If no background screen is specified, the first background screen is foregrounded. By default, foregrounding causes the current screen to be swapped with the backgrounded screen. Capitalizing the first letter of the command, i.e. *Fg*, will foreground the backgrounded screen in a new screen instead of swapping it with the current screen. Line: Set to the current line when the screen was last edited. Options: None. -- Command: [range] g[lobal] /pattern/ [commands] -- Command: [range] v /pattern/ [commands] Apply commands to lines matching (or not matching) a pattern. The lines within the given range that match "`g[lobal]'", or do not match "`v'" the given pattern are selected. Then, the specified *ex* command(s) are executed with the current line "`.'" set to each selected line. If no range is specified, the entire file is searched for matching, or not matching, lines. Multiple commands can be specified, one per line, by escaping each `'character with a backslash, or by separating commands with a "`|'" character. If no commands are specified, the command defaults to the *print* command. For the *append*, *change* and *insert* commands, the input text must be part of the global command line. In this case, the terminating period can be omitted if it ends the commands. The *visual* command may also be specified as one of the *ex* commands. In this mode, input is taken from the terminal. Entering a *Q* command in *vi* mode causes the next line matching the pattern to be selected and *vi* to be reentered, until the list is exhausted. The *global*, *v* and *undo* commands cannot be used as part of these commands. The editor options `autoindent', `autoprint' and `report' are turned off for the duration of the *global* and *v* commands. Line: The last line modified. Options: Affected by the `ignorecase' and `magic' options. Turns off the `autoindent', `autoprint' and `report' options. -- Command: he[lp] Display a help message. Line: Unchanged. Options: None. -- Command: [line] i[nsert][!] The input text is inserted before the specified line. Following the command name with a "`!'" character causes the `autoindent' option setting to be toggled for the duration of this command. Line: Set to the last line input; if no lines were input, set to the line before the target line, or to the first line of the file if there are no lines preceding the target line. Affected by the `autoindent' and `number' options. -- Command: [range] j[oin][!] [ Join lines of text together. A `count'specified to the *join* command specifies that the last line of the `range'plus `count'subsequent lines will be joined. (Note, this differs by one from the general rule where only `count'- 1 subsequent lines are affected.) If the current line ends with a whitespace character, all whitespace is stripped from the next line. Otherwise, if the next line starts with a open parenthesis "`('", do nothing. Otherwise, if the current line ends with a question mark "`?'", period "`.'" or exclamation point "`!'", insert two spaces. Otherwise, insert a single space. Appending a "`!'" character to the command name causes a simpler join with no white-space processing. Line: Unchanged. Options: None. -- Command: [range] l[ist] [ Display the lines unambiguously. Tabs are displayed as "`^I'", and the end of the line is marked with a "`$'" character. Line: Set to the last line displayed. Options: Affected by the `number' option. -- Command: map[!] [ Define or display maps (for *vi* only). If "`lhs'" and "`rhs'" are not specified, the current set of command mode maps are displayed. If a "`!'" character is appended to to the command, the text input mode maps are displayed. Otherwise, when the "`lhs'" character sequence is entered in *vi*, the action is as if the corresponding "`rhs'" had been entered. If a "`!'" character is appended to the command name, the mapping is effective during text input mode, otherwise, it is effective during command mode. This allows "`lhs'" to have two different macro definitions at the same time: one for command mode and one for input mode. Whitespace characters require escaping with a `'character to be entered in the `lhs'string in visual mode. Normally, keys in the `rhs'string are remapped (see the `remap' option), and it is possible to create infinite loops. However, keys which map to themselves are not further remapped, regardless of the setting of the `remap' option. For example, the command "`:map n nz.'" maps the "`n'" key to the *n* and *z* commands. To exit an infinitely looping map, use the terminal `'character. Line: Unchanged. Options: Affected by the `remap' option. -- Command: [line] ma[rk] -- Command: [line] k Mark the line with the mark `'. The expressions "`''" and "``'" can then be used as an address in any command that uses one. Line: Unchanged. Options: None. -- Command: [range] m[ove] line Move the specified lines after the target line. A target line of 0 places the lines at the beginning of the file. Line: Set to the first of the moved lines. Options: None. -- Command: mk[exrc][!] file Write the abbreviations, editor options and maps to the specified file. Information is written in a form which can later be read back in using the *ex* *source* command. If `file'already exists, the *mkexrc* command will fail. This check can be overridden by appending a "`!'" character to the command. Line: Unchanged. Options: None. -- Command: n[ext][!] [ Edit the next file from the argument list. The *next* command will fail if the file has been modified since the last complete write. This check can be overridden by appending the "`!'" character to the command name. The argument list can optionally be replaced by specifying a new one as arguments to this command. In this case, editing starts with the first file on the new list. Capitalizing the first letter of the command, i.e. *Next*, while in *vi* mode, will set the argument list and edit the file in a new screen. In this case, any modifications to the current file are ignored. Line: Set as described for the *edit* command. Options: Affected by the options `autowrite' and `writeany'. -- Command: [line] o[pen] /pattern/ [flags] Enter open mode. Open mode is the same as being in *vi*, but with a one-line window. All the standard *vi* commands are available. If a match is found for the optional RE argument, the cursor is set to the start of the matching pattern. _This command is not yet implemented._ Line: Unchanged, unless the optional RE is specified, in which case it is set to the line where the matching pattern is found. Options: Affected by the `open' option. -- Command: pre[serve] Save the file in a form that can later be recovered using the *ex* *-r* option. When the file is preserved, an email message is sent to the user. Line: Unchanged. Options: None. -- Command: prev[ious][!] Edit the previous file from the argument list. The *previous* command will fail if the file has been modified since the last complete write. This check can be overridden by appending the "`!'" character to the command name. Capitalizing the first letter of the command, i.e. *Previous*, while in *vi* mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. Line: Set as described for the *edit* command. Options: Affected by the options `autowrite' and `writeany'. None. -- Command: [range] p[rint] [ Display the specified lines. Line: Set to the last line displayed. Options: Affected by the `list' and `number' option. -- Command: [line] pu[t] [ Append buffer contents to the current line. If a buffer is specified, its contents are appended to the line, otherwise, the contents of the unnamed buffer are used. Line: Set to the line after the current line. Options: None. -- Command: q[uit][!] End the editing session. If the file has been modified since the last complete write, the *quit* command will fail. This check may be overridden by appending a "`!'" character to the command. If there are more files to edit, the *quit* command will fail. Appending a "`!'" character to the command name or entering two *quit* commands (i.e. *wq*, *quit*, *xit* or *ZZ*) in a row) will override this check and the editor will exit. Line: Unchanged. Options: None. -- Command: [line] r[ead][!] [ Read a file. A copy of the specified file is appended to the line. If `line'is 0, the copy is inserted at the beginning of the file. If no file is specified, the current file is read; if there is no current file, then `file'becomes the current file. If there is no current file and no `file'is specified, then the *read* command will fail. If `file'is preceded by a "`!'" character, `file'is treated as if it were a shell command, and passed to the program named by the `shell' edit option. The standard and standard error outputs of that command are read into the file after the specified line. The special meaning of the "`!'" character can be overridden by escaping it with a backslash "`e'" character. Line: When executed from *ex*, the current line is set to the last line read. When executed from *vi*, the current line is set to the first line read. Options: None. -- Command: rec[over] file Recover `file'if it was previously saved. If no saved file by that name exists, the *recover* command behaves equivalently to the *edit* command. Line: Set as described for the *edit* command. Options: None. -- Command: res[ize] [ *Vi* mode only. Grow or shrink the current screen. If `size'is a positive, signed number, the current screen is grown by that many lines. If `size'is a negative, signed number, the current screen is shrunk by that many lines. If `size'is not signed, the current screen is set to the specified `size'. Applicable only to split screens. Line: Unchanged. Options: None. -- Command: rew[ind][!] Rewind the argument list. If the current file has been modified since the last complete write, the *rewind* command will fail. This check may be overridden by appending the "`!'" character to the command. Otherwise, the current file is set to the first file in the argument list. Line: Set as described for the *edit* command. Options: Affected by the `autowrite' and `writeany' options. -- Command: se[t] [ Display or set editor options. When no arguments are specified, the editor option `term', and any editor options whose values have been changed from the default settings are displayed. If the argument `all'is specified, the values of all of editor options are displayed. Specifying an option name followed by the character "`?'" causes the current value of that option to be displayed. The "`?'" can be separated from the option name by whitespace characters. The "`?'" is necessary only for Boolean valued options. Boolean options can be given values by the form "`set option'" to turn them on, or "`set nooption'" to turn them off. String and numeric options can be assigned by the form "`set option=value'". Any whitespace characters in strings can be included literally by preceding each with a backslash. More than one option can be set or listed by a single set command, by specifying multiple arguments, each separated from the next by whitespace characters. Line: Unchanged. Options: None. -- Command: sh[ell] Run the shell program. The program named by the `shell' option is run with a *-i* (for interactive) flag. Editing is resumed when that program exits. Line: Unchanged. Options: Affected by the `shell' option. -- Command: so[urce] file Read and execute *ex* commands from a file. *Source* commands may be nested. Line: Unchanged. Options: None. -- Command: [range] s[ubstitute] [ -- Command: [range] & [ -- Command: [range] ~ [ Make substitutions. Replace the first instance of `pattern'with the string `replace'on the specified line(s). If the "`/pattern/repl/'" argument is not specified, the "`/pattern/repl/'" from the previous *substitute* command is used. Any character other than an alphabetic, numeric, or backslash character may be used as the delimiter. If `options'includes the letter "`c'" (confirm), you will be prompted for confirmation before each replacement is done. An affirmative response (in English, a "`y'" character) causes the replacement to be made. A quit response (in English, a "`q'" character) causes the *substitute* command to be terminated. Any other response causes the replacement not to be made, and the *substitute* command continues. If `options'includes the letter "`g'" (global), all nonoverlapping instances of `pattern'in the line are replaced. The *&* version of the command is the same as not specifying a pattern or replacement string to the *substitute* command, and the "`&'" is replaced by the pattern and replacement information from the previous substitute command. The *~* version of the command is the same as *&* and *s*, except that the search pattern used is the last RE used in _any_ command, not necessarily the one used in the last *substitute* command. For example, in the sequence s/red/blue/ /green ~ the "`~'" is equivalent to "`s/green/blue/'". The *substitute* command may be interrupted, using the terminal interrupt character. All substitutions completed before the interrupt are retained. Line: Set to the last line upon which a substitution was made. Options: Affected by the `ignorecase' and `magic' option. -- Command: su[spend][!] -- Command: st[op][!] -- Comamnd: Suspend the edit session. Appending a "`!'" character to these commands turns off the `autowrite' option for the command. Line: Unchanged. Options: Affected by the `autowrite' and `writeany' options. -- Command: ta[g][!] tagstring Edit the file containing the specified tag. If the tag is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the *tag* command will fail. This check can be overridden by appending the "`!'" character to the command name. The *tag* command searches for `tagstring'in the tags file(s) specified by the `tags' option. (See `ctags'(1) for more information on tags files.) Capitalizing the first letter of the command, i.e. *Tag*, while in *vi* mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. Line: Set to the line indicated by the tag. Options: Affected by the `autowrite', `taglength', `tags' and `writeany' options. -- Command: tagn[ext][!] Edit the file containing the next context for the current tag. If the context is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the *tagnext* command will fail. This check can be overridden by appending the "`!'" character to the command name. Capitalizing the first letter of the command, i.e. *Tagnext*, while in *vi* mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. Line: Set to the line indicated by the tag. Options: Affected by the `autowrite' and `writeany' options. -- Command: tagp[op][!] [ Pop to the specified tag in the tags stack. If neither `file'or `number'is specified, the *tagpop* command pops to the most recent entry on the tags stack. If `file'or `number'is specified, the *tagpop* command pops to the most recent entry in the tags stack for that file, or numbered entry in the tags stack, respectively. (See the *display* command for information on displaying the tags stack.) If the file has been modified since the last complete write, the *tagpop* command will fail. This check may be overridden by appending a "`!'" character to the command name. Line: Set to the line indicated by the tag. Options: Affected by the `autowrite' and `writeany' options. -- Command: tagp[rev][!] Edit the file containing the previous context for the current tag. If the context is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the *tagprev* command will fail. This check can be overridden by appending the "`!'" character to the command name. Capitalizing the first letter of the command, i.e. *Tagprev*, while in *vi* mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. Line: Set to the line indicated by the tag. Options: Affected by the `autowrite' and `writeany' options. -- Command: tagt[op][!] Pop to the least recent tag on the tags stack, clearing the tags stack. If the file has been modified since the last complete write, the *tagtop* command will fail. This check may be overridden by appending a "`!'" character to the command name. Line: Set to the line indicated by the tag. Options: Affected by the `autowrite' and `writeany' options. -- Command: una[bbrev] lhs Delete an abbreviation. Delete `lhs'from the current list of abbreviations. Line: Unchanged. Options: None. -- Command: u[ndo] Undo the last change made to the file. Changes made by *global*, *v*, *visual* and map sequences are considered a single command. If repeated, the *u* command alternates between these two states, and is its own inverse. Line: Set to the last line modified by the command. Options: None. -- Command: unm[ap][!] lhs Unmap a mapped string. Delete the command mode map definition for `lhs'. If a "`!'" character is appended to the command name, delete the text input mode map definition instead. Line: Unchanged. Options: None. -- Command: ve[rsion] Display the version of the *ex/vi* editor. -- Command: [line] vi[sual] [ *Ex* mode only. Enter *vi*. The `type'is optional, and can be "`-'", "`+'" or "`^'", as in the *ex* *z* command, to specify the position of the specified line in the screen window. (The default is to place the line at the top of the screen window.) A `count'specifies the number of lines that will initially be displayed. (The default is the value of the `window' editor option.) Line: Unchanged unless `line'is specified, in which case it is set to that line. Options: None. -- Command: vi[sual][!] [ *Vi* mode only. Edit a new file. Identical to the "`edit[!] [+cmd] [file]'" command. Capitalizing the first letter of the command, i.e. *Visual*, will edit the file in a new screen. In this case, any modifications to the current file are ignored. -- Command: viu[sage] [ Display usage for a *vi* command. If `command'is specified, a usage statement for that command is displayed. Otherwise, usage statements for all *vi* commands are displayed. Line: Unchanged. Options: None. -- Command: [range] w[rite][!] [ -- Command: [range] w[rite] [ -- Command: [range] wn[!] [ -- Command: [range] wq[!] [ Write the file. The specified lines (the entire file, if no range is given) is written to `file'. If `file'is not specified, the current pathname is used. If `file'is specified, and it exists, or if the current pathname was set using the *file* command, and the file already exists, these commands will fail. Appending a "`!'" character to the command name will override this check and the write will be attempted, regardless. Specifying the optional "`>>'" string will cause the write to be appended to the file, in which case no tests are made for the file already existing. If the file is preceded by a "`!'" character, the program named by the shell edit option is invoked with file as its second argument, and the specified lines are passed as standard input to that command. The "`!'" in this usage must be separated from command name by at least one whitespace character. The special meaning of the "`!'" may be overridden by escaping it with a backslash "`e'" character. The *wq* version of the write command will exit the editor after writing the file, if there are no further files to edit. Appending a "`!'" character to the command name or entering two "quit" commands (i.e. *wq*, *quit*, *xit* or *ZZ*) in a row) will override this check and the editor will exit, ignoring any files that have not yet been edited. The *wn* version of the write command will move to the next file after writing the file, unless the write fails. Line: Unchanged. Options: Affected by the `readonly' and `writeany' options. -- Command: [range] x[it][!] [ Write the file if it has been modified. The specified lines are written to `file', if the file has been modified since the last complete write to any file. If no `range'is specified, the entire file is written. The *xit* command will exit the editor after writing the file, if there are no further files to edit. Appending a "`!'" character to the command name or entering two "quit" commands (i.e. *wq*, *quit*, *xit* or *ZZ*) in a row) will override this check and the editor will exit, ignoring any files that have not yet been edited. Line: Unchanged. Options: Affected by the `readonly' and `writeany' options. -- Command: [range] ya[nk] [ Copy the specified lines to a buffer. If no buffer is specified, the unnamed buffer is used. Line: Unchanged. Options: None. -- Command: [line] z [ Adjust the window. If no `type'is specified, then `count'lines following the specified line are displayed. The default `count'is the value of the `window' option. The `type'argument changes the position at which `line'is displayed on the screen by changing the number of lines displayed before and after `line'. The following `type'characters may be used: - Place the line at the bottom of the screen. + Place the line at the top of the screen. . Place the line in the middle of the screen. ^ Write out count lines starting `count * 2'lines before `line'; the net effect of this is that a "`z^'" command following a *z* command writes the previous page. = Center `line'on the screen with a line of hyphens displayed immediately before and after it. The number of preceding and following lines of text displayed are reduced to account for those lines. Line: Set to the last line displayed, with the exception of the "`='" `type', where the current line is set to the line specified by the command. Options: Affected by the `scroll' option. 18 Set Options ************** There are a large number of options that may be set (or unset) to change the editor's behavior. This section describes the options, their abbreviations and their default values. In each entry below, the first part of the tag line is the full name of the option, followed by any equivalent abbreviations. (Regardless of the abbreviations, it is only necessary to use the minimum number of characters necessary to distinguish an abbreviation from all other commands for it to be accepted, in *nex*/*nvi*. Historically, only the full name and the official abbreviations were accepted by *ex*/*vi*. Using full names in your startup files and environmental variables will probably make them more portable.) The part in square brackets is the default value of the option. Most of the options are boolean, i.e. they are either on or off, and do not have an associated value. Options apply to both *ex* and *vi* modes, unless otherwise specified. With a few exceptions, all options are settable per screen, i.e. the `tags' option can be set differently in each screen. The exceptions are the `columns', `lines', `secure' and `term' options. Changing these options modifies the respective information for all screens. For information on modifying the options or to display the options and their current values, see the "set" command in the section entitled "*Ex Commands*" . * *altwerase [off]* *Vi* only. Change how *vi* does word erase during text input. When this option is set, text is broken up into three classes: alphabetic, numeric and underscore characters, other nonblank characters, and blank characters. Changing from one class to another marks the end of a word. In addition, the class of the first character erased is ignored (which is exactly what you want when erasing pathname components). * *autoindent, ai [off]* If this option is set, whenever you create a new line (using the *vi* *A*, *a*, *C*, *c*, *I*, *i*, *O*, *o*, *R*, *r*, *S*, and *s* commands, or the *ex* *append*, *change*, and *insert* commands) the new line is automatically indented to align the cursor with the first nonblank character of the line from which you created it. Lines are indented using tab characters to the extent possible (based on the value of the `tabstop' option) and then using space characters as necessary. For commands inserting text into the middle of a line, any blank characters to the right of the cursor are discarded, and the first nonblank character to the right of the cursor is aligned as described above. The indent characters are themselves somewhat special. If you do not enter more characters on the new line before moving to another line, or entering `', the indent character will be deleted and the line will be empty. For example, if you enter `'twice in succession, the line created by the first `'will not have any characters in it, regardless of the indentation of the previous or subsequent line. Indent characters also require that you enter additional erase characters to delete them. For example, if you have an indented line, containing only blanks, the first `'character you enter will erase up to end of the indent characters, and the second will erase back to the beginning of the line. (Historically, only the `'key would erase the indent characters. Both the `'key and the usual erase keys work in *nvi*.) In addition, if the cursor is positioned at the end of the indent characters, the keys "`0'" will erase all of the indent characters for the current line, resetting the indentation level to 0. Similarly, the keys "`^'" will erase all of the indent characters for the current line, leaving the indentation level for future created lines unaffected. Finally, if the `autoindent' option is set, the *S* and *cc* commands change from the first nonblank of the line to the end of the line, instead of from the beginning of the line to the end of the line. * *autoprint, ap [off]* *Ex* only. Cause the current line to be automatically displayed after the *ex* commands *<*, *>*, *copy*, *delete*, *join*, *move*, *put*, *t*, *Undo*, and *undo*. This automatic display is suppressed during *global* and *v* commands, and for any command where optional flags are used to explicitly display the line. * *autowrite, aw [off]* If this option is set, the *vi* *!*, *^^*, *^]* and ** commands, and the *ex* *edit*, *next*, *rewind*, *stop*, *suspend*, *tag*, *tagpop*, and *tagtop* commands automatically write the current file back to the current file name if it has been modified since it was last written. If the write fails, the command fails and goes no further. Appending the optional force flag character "`!'" to the *ex* commands *next*, *rewind*, *stop*, *suspend*, *tag*, *tagpop*, and *tagtop* stops the automatic write from being attempted. (Historically, the *next* command ignored the optional force flag.) Note, the *ex* commands *edit*, *quit*, *shell*, and *xit* are _not_ affected by the `autowrite' option. The `autowrite' option is ignored if the file is considered read-only for any reason. * *backup [""]* If this option is set, it specifies a pathname used as a backup file, and, whenever a file is written, the file's current contents are copied to it. The pathname is "`#'", "`%'" and "`!'" expanded. If the first character of the pathname is "`N'", a version number is appended to the pathname (and the "`N'" character is then discarded). Version numbers are always incremented, and each backup file will have a version number one greater than the highest version number currently found in the directory. Backup files must be regular files, owned by the real user ID of the user running the editor, and not accessible by any other user. * *beautify, bf [off]* If this option is set, all control characters that are not currently being specially interpreted, other than `', `', and `', are discarded from commands read in by *ex* from command files, and from input text entered to *vi* (either into the file or to the colon command line). Text files read by *ex*/*vi* are _not_ affected by the `beautify' option. * *cdpath [environment variable CDPATH, or current directory]* This option is used to specify a colon separated list of directories which are used as path prefixes for any relative path names used as arguments for the *cd* command. The value of this option defaults to the value of the environmental variable `CDPATH'if it is set, otherwise to the current directory. For compatibility with the POSIX 1003.2 shell, the *cd* command does _not_ check the current directory as a path prefix for relative path names unless it is explicitly specified. It may be so specified by entering an empty string or a "`.'" character into the `CDPATH'variable or the option value. * *cedit [no default]* This option adds the ability to edit the colon command-line history. This option is set to a string. Whenever the first character of that string is entered on the colon command line, you will enter a normal editing window on the collected commands that you've entered on the *vi* colon command-line. You may then modify and/or execute the commands. All normal text editing is available, except that you cannot use ** to switch to an alternate screen. Entering a ** will execute the current line of the screen window as an ex command in the context of the screen from which you created the colon command-line screen, and you will then return to that screen. Because of *vi*'s parsing rules, it can be difficult to set the colon command-line edit character to the `'character. To set it to `', use "`set cedit='". If the `cedit' edit option is set to the same character as the `filec' edit option, *vi* will perform colon command-line editing if the character is entered as the first character of the line, otherwise, *vi* will perform file name expansion. * *columns, co [80]* The number of columns in the screen. Setting this option causes *ex*/*vi* to set (or reset) the environmental variable `COLUMNS'. See the section entitled "*Sizing the Screen*" more information. * *comment [off]* *Vi* only. If the first non-empty line of the file begins with the string "`#'", "`/*'" or "`//'", this option causes *vi* to skip to the end of that shell, C or C++ comment (probably a terribly boring legal notice) before displaying the file. * *directory, dir [environment variable TMPDIR, or /tmp]* The directory where temporary files are created. The environmental variable `TMPDIR'is used as the default value if it exists, otherwise `/tmp'is used. * *edcompatible, ed [off]* Remember the values of the "c" and "g" suffixes to the *substitute* commands, instead of initializing them as unset for each new command. Specifying pattern and replacement strings to the *substitute* command unsets the "c" and "g" suffixes as well. * *escapetime [1]* The 10th's of a second *ex*/*vi* waits for a subsequent key to complete an `'key mapping. * *errorbells, eb [off]* *Ex* only. *Ex* error messages are normally presented in inverse video. If that is not possible for the terminal, setting this option causes error messages to be announced by ringing the terminal bell. * *exrc, ex [off]* If this option is turned on in the EXINIT environment variables, or the system or $HOME startup files, the local startup files are read, unless they are the same as the system or $HOME startup files or fail to pass the standard permission checks. See the section entitled "*Startup Information*" for more information. * *extended [off]* This option causes all regular expressions to be treated as POSIX 1003.2 Extended Regular Expressions (which are similar to historic `egrep'(1) style expressions). * *filec [no default]* This option adds the ability to do shell expansion when entering input on the colon command line. This option is set to a string. Whenever the first character of that string is entered on the colon command line, the delimited string immediately before the cursor is expanded as if it were followed by a `*'character, and file name expansion for the *ex* edit command was done. If no match is found, the screen is flashed and text input resumed. If a single match results, that match replaces the expanded text. In addition, if the single match is for a directory, a `/'character is appended and file completion is repeated. If more than a single match results, any unique prefix shared by the matches replaces the expanded text, the matches are displayed, and text input resumed. Because of *vi*'s parsing rules, it can be difficult to set the path completion character to two command values, `'and `'. To set it to `', use "`set filec='". To set it to `', use "`set filec=e'". If the `cedit' edit option is set to the same character as the `filec' edit option, *vi* will perform colon command-line editing if the character is entered as the first character of the line, otherwise, *vi* will perform file name expansion. * *flash [on]* This option causes the screen to flash instead of beeping the keyboard, on error, if the terminal has the capability. * *hardtabs, ht [8]* This option defines the spacing between hardware tab settings, i.e. the tab expansion done by the operating system and/or the terminal itself. As *nex*/*nvi* never writes `'characters to the terminal, unlike historic versions of *ex*/*vi*, this option does not currently have any affect. * *iclower [off]* The `iclower' edit option makes all Regular Expressions case-insensitive, as long as an upper-case letter does not appear in the search string. * *ignorecase, ic [off]* This option causes regular expressions, both in *ex* commands and in searches, to be evaluated in a case-insensitive manner. * *keytime [6]* The 10th's of a second *ex*/*vi* waits for a subsequent key to complete a key mapping. * *leftright [off]* *Vi* only. This option causes the screen to be scrolled left-right to view lines longer than the screen, instead of the traditional *vi* screen interface which folds long lines at the right-hand margin of the terminal. * *lines, li [24]* *Vi* only. The number of lines in the screen. Setting this option causes *ex*/*vi* to set (or reset) the environmental variable `LINES'. See the section entitled "*Sizing the Screen*" for more information. * *lisp [off]* *Vi* only. This option changes the behavior of the *vi* *(*, *)*, *{*, *}*, *[[* and *]]* commands to match the Lisp language. Also, the `autoindent' option's behavior is changed to be appropriate for Lisp. _This option is not yet implemented._ * *list [off]* This option causes lines to be displayed in an unambiguous fashion. Specifically, tabs are displayed as control characters, i.e. "`^I'", and the ends of lines are marked with a "`$'" character. * *lock [on]* This option causes the editor to attempt to get an exclusive lock on any file being edited, read or written. Reading or writing a file that cannot be locked produces a warning message, but no other effect. Editing a file that cannot be locked results in a read only edit session, as if the `readonly' edit option were set. * *magic [on]* This option is on by default. Turning the `magic' option off causes all regular expression characters except for "`^'" and "`$'", to be treated as ordinary characters. To re-enable characters individually, when the `magic' option is off, precede them with a backslash "`e'" character. See the section entitled "*Regular Expressions and Replacement Strings*" for more information. * *matchtime [7]* *Vi* only. The 10th's of a second *vi* pauses on the matching character when the `showmatch' option is set. * *mesg [on]* This option allows other users to contact you using the `talk'(1) and `write'(1) utilities, while you are editing. *Ex*/*vi* does not turn message on, i.e. if messages were turned off when the editor was invoked, they will stay turned off. This option only permits you to disallow messages for the edit session. See the `mesg'(1) utility for more information. * *msgcat [./]* This option selects a message catalog to be used to display error and informational messages in a specified language. If the value of this option ends with a '/', it is treated as the name of a directory that contains a message catalog "`vi_XXXX'", where "`XXXX'" is the value of the `LANG'environmental variable, if it's set, or the value of the `LC_MESSAGES'environmental variable if it's not. If neither of those environmental variables are set, or if the option doesn't end in a '/', the option is treated as the full path name of the message catalog to use. If any messages are missing from the catalog, the backup text (English) is used instead. See the distribution file `catalog/README'for additional information on building and installing message catalogs. * *modelines, modeline [off]* If the `modelines' option is set, *ex*/*vi* has historically scanned the first and last five lines of each file as it is read for editing, looking for any *ex* commands that have been placed in those lines. After the startup information has been processed, and before the user starts editing the file, any commands embedded in the file are executed. Commands were recognized by the letters "e" or "v" followed by "x" or "i", at the beginning of a line or following a tab or space character, and followed by a ":", an *ex* command, and another ":". This option is a security problem of immense proportions, and should not be used under any circumstances. _This option will never be implemented._ * *noprint [""]* Characters that are never handled as printable characters. By default, the C library function `isprint'(3) is used to determine if a character is printable or not. This edit option overrides that decision. * *number, nu [off]* Precede each line displayed with its current line number. * *octal [off]* Display unknown characters as octal numbers "`"e###"'", instead of the default hexadecimal "`"ex##"'". * *open [on]* *Ex* only. If this option is not set, the *open* and *visual* commands are disallowed. * *optimize, opt [on]* *Vi* only. Throughput of text is expedited by setting the terminal not to do automatic carriage returns when printing more than one (logical) line of output, greatly speeding output on terminals without addressable cursors when text with leading white space is printed. _This option is not yet implemented._ * *paragraphs, para [IPLPPPQPP LIpplpipbp]* *Vi* only. Define additional paragraph boundaries for the *{* and *}* commands. The value of this option must be a character string consisting of zero or more character pairs. In the text to be edited, the character string `.', (where `'is one of the character pairs in the option's value) defines a paragraph boundary. For example, if the option were set to `LaA##', then all of the following additional paragraph boundaries would be recognized: .La .A .## * *path []* The path option can be used to specify a -separated list of paths, similar to the `PATH'environment variable in the shells. If this option is set, the name of the file to be edited is not an absolute pathname, the first component of the filename is not "`.'" or "`..'", and the file to be edited doesn't exist in the current directory, the elements of the `path' option are sequentially searched for a file of the specified name. If such a file is found, it is edited. * *print [""]* Characters that are always handled as printable characters. By default, the C library function `isprint'(3) is used to determine if a character is printable or not. This edit option overrides that decision. * *prompt [on]* *Ex* only. This option causes *ex* to prompt for command input with a "`:'" character; when it is not set, no prompt is displayed. * *readonly, ro [off]* This option causes a force flag to be required to attempt to write the file. Setting this option is equivalent to using the *-R* command line option, or executing the *vi* program using the name *view*. The `readonly' edit option is not usually persistent, like other edit options. If the *-R* command line option is set, *vi* is executed as *view*, or the `readonly' edit option is explicitly set, all files edited in the screen will be marked readonly, and the force flag will be required to write them. However, if none of these conditions are true, or the `readonly' edit option is explicitly unset, then the `readonly' edit option will toggle based on the write permissions of the file currently being edited as of when it is loaded into the edit buffer. In other words, the `readonly' edit option will be set if the current file lacks write permissions, and will not be set if the user has write permissions for the file. * *recdir [/var/tmp/vi.recover]* The directory where recovery files are stored. If you change the value of `recdir', be careful to choose a directory whose contents are not regularly deleted. Bad choices include directories in memory based filesystems, or `/tmp', on most systems, as their contents are removed when the machine is rebooted. Public directories like `/usr/tmp'and `/var/tmp'are usually safe, although some sites periodically prune old files from them. There is no requirement that you use a public directory, e.g. a sub-directory of your home directory will work fine. Finally, if you change the value of `recdir', you must modify the recovery script to operate in your chosen recovery area. See the section entitled "*Recovery*" for further information. * *redraw, re [off]* *Vi* only. The editor simulates (using great amounts of output), an intelligent terminal on a dumb terminal (e.g. during insertions in *vi* the characters to the right of the cursor are refreshed as each input character is typed). _This option is not yet implemented._ * *remap [on]* If this option is set, it is possible to define macros in terms of other macros. Otherwise, each key is only remapped up to one time. For example, if "`A'" is mapped to "`B'", and "`B'" is mapped to "`C'", The keystroke "`A'" will be mapped to "`C'" if the `remap' option is set, and to "`B'" if it is not set. * *report [5]* Set the threshold of the number of lines that need to be changed or yanked before a message will be displayed to the user. For everything but the yank command, the value is the largest value about which the editor is silent, i.e. by default, 6 lines must be deleted before the user is notified. However, if the number of lines yanked is greater than _or equal to_ the set value, it is reported to the user. * *ruler [off]* *Vi* only. Display a row/column ruler on the colon command line. * *scroll, scr [(environment variable LINES - 1) / 2]* Set the number of lines scrolled by the *ex* ** and ** commands. Historically, the *ex* *z* command, when specified without a count, used two times the size of the scroll value; the POSIX 1003.2 standard specified the window size, which is a better choice. * *searchincr [off]* The `searchincr' edit option makes the search commands */* and *?* incremental, i.e. the screen is updated and the cursor moves to the matching text as the search pattern is entered. If the search pattern is not found, the screen is beeped and the cursor remains on the colon-command line. Erasing characters from the search pattern backs the cursor up to the previous matching text. * *sections, sect [NHSHH HUnhsh]* *Vi* only. Define additional section boundaries for the *[[* and *]]* commands. The `sections' option should be set to a character string consisting of zero or more character pairs. In the text to be edited, the character string `.', (where `'is one of the character pairs in the option's value), defines a section boundary in the same manner that `paragraphs' option boundaries are defined. * *secure [off]* The `secure' edit option turns off all access to external programs. This means that the versions of the *read* and *write* commands that filter text through other programs, the *vi* *!* and ** commands, the *ex* *!*, *script*, *shell*, *stop* and *suspend* commands and file name expansion will not be permitted. Once set, the `secure' edit option may not be unset. * *shell, sh [environment variable SHELL, or /bin/sh]* Select the shell used by the editor. The specified path is the pathname of the shell invoked by the *vi* *!* shell escape command and by the *ex* *shell* command. This program is also used to resolve any shell meta-characters in *ex* commands. * *shellmeta [~{[*?$`'"\]* The set of characters that *ex* checks for when doing file name expansion. If any of the specified characters are found in the file name arguments to the *ex* commands, the arguments are expanded using the program defined by the `shell' option. The default set of characters is a union of meta characters from the Version 7 and the Berkeley C shell. * *shiftwidth, sw [8]* Set the autoindent and shift command indentation width. This width is used by the `autoindent' option and by the *<*, *>*, and *shift* commands. * *showmatch, sm [off]* *Vi* only. This option causes *vi*, when a "`}'" or "`)'" is entered, to briefly move the cursor the matching "`{'" or "`('". See the `matchtime' option for more information. * *showmode, smd [off]* *Vi* only. This option causes *vi* to display a string identifying the current editor mode on the colon command line. The string is preceded by an asterisk ("*") if the file has been modified since it was last completely written, * *sidescroll [16]* *Vi* only. Sets the number of columns that are shifted to the left or right, when *vi* is doing left-right scrolling and the left or right margin is crossed. See the `leftright' option for more information. * *slowopen, slow [off]* This option affects the display algorithm used by *vi*, holding off display updating during input of new text to improve throughput when the terminal in use is slow and unintelligent. _This option is not yet implemented._ * *sourceany [off]* If this option is turned on, *vi* historically read startup files that were owned by someone other than the editor user. See the section entitled "*Startup Information*" for more information. This option is a security problem of immense proportions, and should not be used under any circumstances. _This option will never be implemented._ * *tabstop, ts [8]* This option sets tab widths for the editor display. * *taglength, tl [0]* This option sets the maximum number of characters that are considered significant in a tag name. Setting the value to 0 makes all of the characters in the tag name significant. * *tags, tag [tags /var/db/libc.tags /sys/kern/tags]* Sets the list of tags files, in search order, which are used when the editor searches for a tag. * *term, ttytype, tty [environment variable TERM]* Set the terminal type. Setting this option causes *ex*/*vi* to set (or reset) the environmental variable `TERM'. * *terse [off]* This option has historically made editor messages less verbose. It has no effect in this implementation. See the `verbose' option for more information. * *tildeop [off]* Modify the *~* command to take an associated motion. * *timeout, to [on]* If this option is set, *ex*/*vi* waits for a specific period for a subsequent key to complete a key mapping (see the `keytime' option). If the option is not set, the editor waits until enough keys are entered to resolve the ambiguity, regardless of how long it takes. * *ttywerase [off]* *Vi* only. This option changes how *vi* does word erase during text input. If this option is set, text is broken up into two classes, blank characters and nonblank characters. Changing from one class to another marks the end of a word. * *verbose [off]* *Vi* only. *Vi* historically bells the terminal for many obvious mistakes, e.g. trying to move past the left-hand margin, or past the end of the file. If this option is set, an error message is displayed for all errors. * *w300 [no default]* *Vi* only. Set the window size if the baud rate is less than 1200 baud. See the `window' option for more information. * *w1200 [no default]* *Vi* only. Set the window size if the baud rate is equal to 1200 baud. See the `window' option for more information. * *w9600 [no default]* *Vi* only. Set the window size if the baud rate is greater than 1200 baud. See the `window' option for more information. * *warn [on]* *Ex* only. This option causes a warning message to the terminal if the file has been modified, since it was last written, before a *!* command. * *window, w, wi [environment variable LINES - 1]* This option determines the default number of lines in a screenful, as displayed by the *z* command. It also determines the number of lines scrolled by the *vi* commands ** and **, and the default number of lines scrolled by the *vi* commands ** and **. The value of window can be unrelated to the real screen size, although it starts out as the number of lines on the screen. See the section entitled "*Sizing the Screen*" for more information. Setting the value of the `window' option is the same as using the *-w* command line option. If the value of the `window' option (as set by the `window', `w300', `w1200' or `w9600' options) is smaller than the actual size of the screen, large screen movements will result in displaying only that smaller number of lines on the screen. (Further movements in that same area will result in the screen being filled.) This can provide a performance improvement when viewing different places in one or more files over a slow link. Resetting the window size does not reset the default number of lines scrolled by the ** and ** commands. * *windowname [off]* *Vi* changes the name of the editor's icon/window to the current file name when it's possible and not destructive, i.e., when the editor can restore it to its original value on exit or when the icon/window will be discarded as the editor exits. If the `windowname' edit option is set, *vi* will change the icon/window name even when it's destructive and the icon/window name will remain after the editor exits. (This is the case for `xterm'(1)). * *wraplen, wl [0]* This option is identical to the `wrapmargin' option, with the exception that it specifies the number of columns from the _left_ margin before the line splits, not the right margin. If both `wraplen' and `wrapmargin' are set, the `wrapmargin' value is used. * *wrapmargin, wm [0]* *Vi* only. If the value of the `wrapmargin' option is non-zero, *vi* will split lines so that they end at least that number of columns before the right-hand margin of the screen. (Note, the value of `wrapmargin' is _not_ a text length. In a screen that is 80 columns wide, the command "`:set wrapmargin=8'" attempts to keep the lines less than or equal to 72 columns wide.) Lines are split at the previous whitespace character closest to the number. Any trailing whitespace characters before that character are deleted. If the line is split because of an inserted `'or `'character, and you then enter another `'character, it is discarded. If wrapmargin is set to 0, or if there is no blank character upon which to split the line, the line is not broken. If both `wraplen' and `wrapmargin' are set, the `wrapmargin' value is used. * *wrapscan, ws [on]* This option causes searches to wrap around the end or the beginning of the file, and back to the starting point. Otherwise, the end or beginning of the file terminates the search. * *writeany, wa [off]* If this option is set, file-overwriting checks that would usually be made before the *write* and *xit* commands, or before an automatic write (see the `autowrite' option), are not made. This allows a write to any file, provided the file permissions allow it. 19 Index ******** nvi-1.81.6/docs/vi.ref/vi.ref.ps0100444000076400001440000235610710720065723015345 0ustar skimousers%!PS-Adobe-2.0 %%Creator: dvips(k) 5.95a Copyright 2005 Radical Eye Software %%Title: vi.dvi %%Pages: 81 %%PageOrder: Ascend %%BoundingBox: 0 0 595 842 %%DocumentFonts: CMBX12 CMTI10 CMR10 CMB10 CMSY10 CMBXTI10 CMTT10 CMSL10 %%+ CMSS10 CMR9 CMTI9 CMTT9 CMTT12 %%DocumentPaperSizes: a4 %%EndComments %DVIPSWebPage: (www.radicaleye.com) %DVIPSCommandLine: dvips -o vi.ref.ps vi.dvi %DVIPSParameters: dpi=600 %DVIPSSource: TeX output 2007.11.18:1744 %%BeginProcSet: tex.pro 0 0 %! /TeXDict 300 dict def TeXDict begin/N{def}def/B{bind def}N/S{exch}N/X{S N}B/A{dup}B/TR{translate}N/isls false N/vsize 11 72 mul N/hsize 8.5 72 mul N/landplus90{false}def/@rigin{isls{[0 landplus90{1 -1}{-1 1}ifelse 0 0 0]concat}if 72 Resolution div 72 VResolution div neg scale isls{ landplus90{VResolution 72 div vsize mul 0 exch}{Resolution -72 div hsize mul 0}ifelse TR}if Resolution VResolution vsize -72 div 1 add mul TR[ matrix currentmatrix{A A round sub abs 0.00001 lt{round}if}forall round exch round exch]setmatrix}N/@landscape{/isls true N}B/@manualfeed{ statusdict/manualfeed true put}B/@copies{/#copies X}B/FMat[1 0 0 -1 0 0] N/FBB[0 0 0 0]N/nn 0 N/IEn 0 N/ctr 0 N/df-tail{/nn 8 dict N nn begin /FontType 3 N/FontMatrix fntrx N/FontBBox FBB N string/base X array /BitMaps X/BuildChar{CharBuilder}N/Encoding IEn N end A{/foo setfont}2 array copy cvx N load 0 nn put/ctr 0 N[}B/sf 0 N/df{/sf 1 N/fntrx FMat N df-tail}B/dfs{div/sf X/fntrx[sf 0 0 sf neg 0 0]N df-tail}B/E{pop nn A definefont setfont}B/Cw{Cd A length 5 sub get}B/Ch{Cd A length 4 sub get }B/Cx{128 Cd A length 3 sub get sub}B/Cy{Cd A length 2 sub get 127 sub} B/Cdx{Cd A length 1 sub get}B/Ci{Cd A type/stringtype ne{ctr get/ctr ctr 1 add N}if}B/CharBuilder{save 3 1 roll S A/base get 2 index get S /BitMaps get S get/Cd X pop/ctr 0 N Cdx 0 Cx Cy Ch sub Cx Cw add Cy setcachedevice Cw Ch true[1 0 0 -1 -.1 Cx sub Cy .1 sub]{Ci}imagemask restore}B/D{/cc X A type/stringtype ne{]}if nn/base get cc ctr put nn /BitMaps get S ctr S sf 1 ne{A A length 1 sub A 2 index S get sf div put }if put/ctr ctr 1 add N}B/I{cc 1 add D}B/bop{userdict/bop-hook known{ bop-hook}if/SI save N @rigin 0 0 moveto/V matrix currentmatrix A 1 get A mul exch 0 get A mul add .99 lt{/QV}{/RV}ifelse load def pop pop}N/eop{ SI restore userdict/eop-hook known{eop-hook}if showpage}N/@start{ userdict/start-hook known{start-hook}if pop/VResolution X/Resolution X 1000 div/DVImag X/IEn 256 array N 2 string 0 1 255{IEn S A 360 add 36 4 index cvrs cvn put}for pop 65781.76 div/vsize X 65781.76 div/hsize X}N /p{show}N/RMat[1 0 0 -1 0 0]N/BDot 260 string N/Rx 0 N/Ry 0 N/V{}B/RV/v{ /Ry X/Rx X V}B statusdict begin/product where{pop false[(Display)(NeXT) (LaserWriter 16/600)]{A length product length le{A length product exch 0 exch getinterval eq{pop true exit}if}{pop}ifelse}forall}{false}ifelse end{{gsave TR -.1 .1 TR 1 1 scale Rx Ry false RMat{BDot}imagemask grestore}}{{gsave TR -.1 .1 TR Rx Ry scale 1 1 false RMat{BDot} imagemask grestore}}ifelse B/QV{gsave newpath transform round exch round exch itransform moveto Rx 0 rlineto 0 Ry neg rlineto Rx neg 0 rlineto fill grestore}B/a{moveto}B/delta 0 N/tail{A/delta X 0 rmoveto}B/M{S p delta add tail}B/b{S p tail}B/c{-4 M}B/d{-3 M}B/e{-2 M}B/f{-1 M}B/g{0 M} B/h{1 M}B/i{2 M}B/j{3 M}B/k{4 M}B/w{0 rmoveto}B/l{p -4 w}B/m{p -3 w}B/n{ p -2 w}B/o{p -1 w}B/q{p 1 w}B/r{p 2 w}B/s{p 3 w}B/t{p 4 w}B/x{0 S rmoveto}B/y{3 2 roll p a}B/bos{/SS save N}B/eos{SS restore}B end %%EndProcSet %%BeginProcSet: texps.pro 0 0 %!

Hewett .sp Revised for version 2.12 by Mark Horton .NH 1 Author's Disclaimer .LP This document does not claim to be 100% complete. There are a few commands listed in the original document that I was unable to test either because I do not speak \fBlisp\fR, because they required programs we don't have, or because I wasn't able to make them work. In these cases I left the command out. The commands listed in this document have been tried and are known to work. It is expected that prospective users of this document will read it once to get the flavor of everything that \fBvi\fR can do and then use it as a reference document. Experimentation is recommended. If you don't understand a command, try it and see what happens. .LP [Note: In revising this document, I have attempted to make it completely reflect version 2.12 of .B vi . It does not attempt to document the VAX version (version 3), but with one or two exceptions (wrapmargin, arrow keys) everything said about 2.12 should apply to 3.1. .I "Mark Horton" ] .NH 1 Notation .LP \fB[option]\fR is used to denote optional parts of a command. Many \fBvi\fR commands have an optional count. \fB[cnt]\fR means that an optional number may precede the command to multiply or iterate the command. \fB{variable item}\fR is used to denote parts of the command which must appear, but can take a number of different values. \fB\fR means that the character or one of the characters in the range described between the two angle brackets is to be typed. For example \fB\fR means the \fBescape\fR key is to be typed. \fB\fR means that a lower case letter is to be typed. \fB^\fR means that the character is to be typed as a \fBcontrol\fR character, that is, with the \fB\fR key held down while simultaneously typing the specified character. In this document control characters will be denoted using the \fIupper case\fR character, but ^ and ^ are equivalent. That is, for example, \fB<^D>\fR is equal to \fB<^d>\fR. The most common character abbreviations used in this list are as follows: .IP 8 escape, octal 033 .IP 8 carriage return, ^M, octal 015 .IP 8 linefeed ^J, octal 012 .IP 8 newline, ^J, octal 012 (same as linefeed) .IP 8 backspace, ^H, octal 010 .IP 8 tab, ^I, octal 011 .IP 8 bell, ^G, octal 07 .IP 8 formfeed, ^L, octal 014 .IP 8 space, octal 040 .IP 8 delete, octal 0177 .sp 1 .NH 1 Basics .LP To run \fBvi\fR the shell variable \fBTERM\fR must be defined and exported to your environment. How you do this depends on which shell you are using. You can tell which shell you have by the character it prompts you for commands with. The Bourne shell prompts with `$', and the C shell prompts with `%'. For these examples, we will suppose that you are using an HP 2621 terminal, whose termcap name is ``2621''. .NH 2 Bourne Shell .LP To manually set your terminal type to 2621 you would type: .DS TERM=2621 export TERM .DE .PP There are various ways of having this automatically or semi-automatically done when you log in. Suppose you usually dial in on a 2621. You want to tell this to the machine, but still have it work when you use a hardwired terminal. The recommended way, if you have the .B tset program, is to use the sequence .DS tset \-s \-d 2621 > tset$$ \&. tset$$ rm tset$$ .DE in your .login (for csh) or the same thing using `.' instead of `source' in your .profile (for sh). The above line says that if you are dialing in you are on a 2621, but if you are on a hardwired terminal it figures out your terminal type from an on-line list. .NH 2 The C Shell .LP To manually set your terminal type to 2621 you would type: .DS setenv TERM 2621 .DE .PP There are various ways of having this automatically or semi-automatically done when you log in. Suppose you usually dial in on a 2621. You want to tell this to the machine, but still have it work when you use a hardwired terminal. The recommended way, if you have the .B tset program, is to use the sequence .DS tset \-s \-d 2621 > tset$$ source tset$$ rm tset$$ .DE in your .login.* .FS * On a version 6 system without environments, the invocation of tset is simpler, just add the line ``tset \-d 2621'' to your .login or .profile. .FE The above line says that if you are dialing in you are on a 2621, but if you are on a hardwired terminal it figures out your terminal type from an on-line list. .NH 1 Normal Commands .LP \fBVi\fR is a visual editor with a window on the file. What you see on the screen is \fBvi\fR's current notion of what your file will contain, (at this point in the file), when it is written out. Most commands do not cause any change in the screen until the complete command is typed. Should you get confused while typing a command, you can abort the command by typing an character. You will know you are back to command level when you hear a . Usually typing an will produce the same result. When \fBvi\fR gets an improperly formatted command it rings the . Following are the \fBvi\fR commands broken down by function. .NH 2 Entry and Exit .LP To enter .B vi on a particular .I file , type .DS \fBvi\fP \fIfile\fP .DE The file will be read in and the cursor will be placed at the beginning of the first line. The first screenfull of the file will be displayed on the terminal. .PP To get out of the editor, type .DS ZZ .DE If you are in some special mode, such as input mode or the middle of a multi-keystroke command, it may be necessary to type first. .NH 2 Cursor and Page Motion .LP .B NOTE: The arrow keys (see the next four commands) on certain kinds of terminals will not work with the PDP-11 version of vi. The control versions or the hjkl versions will work on any terminal. Experienced users prefer the hjkl keys because they are always right under their fingers. Beginners often prefer the arrow keys, since they do not require memorization of which hjkl key is which. The mnemonic value of hjkl is clear from looking at the keyboard of an adm3a. .sp .IP "[cnt] or [cnt]h or [cnt]\(<-" 16 .br Move the cursor to the left one character. Cursor stops at the left margin of the page. If cnt is given, these commands move that many spaces. .IP "[cnt]^N or [cnt]j or [cnt]\(da or [cnt]" 16 .br Move down one line. Moving off the screen scrolls the window to force a new line onto the screen. Mnemonic: \fBN\fRext .IP "[cnt]^P or [cnt]k or [cnt]\(ua" 16 .br Move up one line. Moving off the top of the screen forces new text onto the screen. Mnemonic: \fBP\fRrevious .IP "[cnt] or [cnt]l or [cnt]\(->" 16 .br Move to the right one character. Cursor will not go beyond the end of the line. .IP [cnt]- 16 Move the cursor up the screen to the beginning of the next line. Scroll if necessary. .IP "[cnt]+ or [cnt]" 16 .sp 1 Move the cursor down the screen to the beginning of the next line. Scroll up if necessary. .IP "[cnt]$" 16 Move the cursor to the end of the line. If there is a count, move to the end of the line "cnt" lines forward in the file. .IP "^" 16 Move the cursor to the beginning of the first word on the line. .IP "0" 16 Move the cursor to the left margin of the current line. .IP "[cnt]|" 16 Move the cursor to the column specified by the count. The default is column zero. .IP "[cnt]w" 16 Move the cursor to the beginning of the next word. If there is a count, then move forward that many words and position the cursor at the beginning of the word. Mnemonic: next-\fBw\fRord .IP "[cnt]W" 16 Move the cursor to the beginning of the next word which follows a "white space" (,, or ). Ignore other punctuation. .IP "[cnt]b" 16 Move the cursor to the preceding word. Mnemonic: \fBb\fRackup-word .IP "[cnt]B" 16 Move the cursor to the preceding word that is separated from the current word by a "white space" (,, or ). .IP "[cnt]e" 16 Move the cursor to the end of the current word or the end of the "cnt"'th word hence. Mnemonic: \fBe\fRnd-of-word .IP "[cnt]E" 16 Move the cursor to the end of the current word which is delimited by "white space" (,, or ). .IP "[line number]G" 16 .br Move the cursor to the line specified. Of particular use are the sequences "1G" and "G", which move the cursor to the beginning and the end of the file respectively. Mnemonic: \fBG\fRo-to .LP .B NOTE: The next four commands (^D, ^U, ^F, ^B) are not true motion commands, in that they cannot be used as the object of commands such as delete or change. .IP "[cnt]^D" 16 Move the cursor down in the file by "cnt" lines (or the last "cnt" if a new count isn't given. The initial default is half a page.) The screen is simultaneously scrolled up. Mnemonic: \fBD\fRown .IP "[cnt]^U" 16 Move the cursor up in the file by "cnt" lines. The screen is simultaneously scrolled down. Mnemonic: \fBU\fRp .IP "[cnt]^F" 16 Move the cursor to the next page. A count moves that many pages. Two lines of the previous page are kept on the screen for continuity if possible. Mnemonic: \fBF\fRorward-a-page .IP "[cnt]^B" 16 Move the cursor to the previous page. Two lines of the current page are kept if possible. Mnemonic: \fBB\fRackup-a-page .IP "[cnt](" 16 Move the cursor to the beginning of the next sentence. A sentence is defined as ending with a ".", "!", or "?" followed by two spaces or a . .IP "[cnt])" 16 Move the cursor backwards to the beginning of a sentence. .IP "[cnt]}" 16 Move the cursor to the beginning of the next paragraph. This command works best inside \fBnroff\fR documents. It understands two sets of \fBnroff\fR macros, \fB\-ms\fR and \fB\-mm\fR, for which the commands ".IP", ".LP", ".PP", ".QP", "P", as well as the nroff command ".bp" are considered to be paragraph delimiters. A blank line also delimits a paragraph. The \fBnroff\fR macros that it accepts as paragraph delimiters is adjustable. See \fBparagraphs\fR under the \fBSet Commands\fR section. .IP "[cnt]{" 16 Move the cursor backwards to the beginning of a paragraph. .IP "]]" 16 Move the cursor to the next "section", where a section is defined by two sets of \fBnroff\fR macros, \fB\-ms\fR and \fB\-mm\fR, in which ".NH", ".SH", and ".H" delimit a section. A line beginning with a sequence, or a line beginning with a "{" are also considered to be section delimiters. The last option makes it useful for finding the beginnings of C functions. The \fBnroff\fR macros that are used for section delimiters can be adjusted. See \fBsections\fR under the \fBSet Commands\fR section. .IP "[[" 16 Move the cursor backwards to the beginning of a section. .IP "%" 16 Move the cursor to the matching parenthesis or brace. This is very useful in C or lisp code. If the cursor is sitting on a \fB( ) {\fR or \fB}\fR the cursor is moved to the matching character at the other end of the section. If the cursor is not sitting on a brace or a parenthesis, \fBvi\fR searches forward until it finds one and then jumps to the match mate. .IP "[cnt]H" 16 If there is no count move the cursor to the top left position on the screen. If there is a count, then move the cursor to the beginning of the line "cnt" lines from the top of the screen. Mnemonic: \fBH\fRome .IP "[cnt]L" 16 If there is no count move the cursor to the beginning of the last line on the screen. If there is a count, then move the cursor to the beginning of the line "cnt" lines from the bottom of the screen. Mnemonic: \fBL\fRast .IP "M" 16 Move the cursor to the beginning of the middle line on the screen. Mnemonic: \fBM\fRiddle .IP "m" 16 This command does not move the cursor, but it \fBmarks\fR the place in the file and the character "" becomes the label for referring to this location in the file. See the next two commands. Mnemonic: \fBm\fRark .B NOTE: The mark command is not a motion, and cannot be used as the target of commands such as delete. .IP "\(aa" 16 Move the cursor to the beginning of the line that is marked with the label "". .IP "\(ga" 16 Move the cursor to the exact position on the line that was marked with with the label "". .IP "\(aa\(aa" 16 Move the cursor back to the beginning of the line where it was before the last "non-relative" move. A "non-relative" move is something such as a search or a jump to a specific line in the file, rather than moving the cursor or scrolling the screen. .IP "\(ga\(ga" 16 Move the cursor back to the exact spot on the line where it was located before the last "non-relative" move. .NH 2 Searches .LP The following commands allow you to search for items in a file. .IP [cnt]f{chr} 16 .sp 1 Search forward on the line for the next or "cnt"'th occurrence of the character "chr". The cursor is placed \fBat\fR the character of interest. Mnemonic: \fBf\fRind character .IP [cnt]F{chr} 16 .sp 1 Search backwards on the line for the next or "cnt"'th occurrence of the character "chr". The cursor is placed \fBat\fR the character of interest. .IP [cnt]t{chr} 16 .sp 1 Search forward on the line for the next or "cnt"'th occurrence of the character "chr". The cursor is placed \fBjust preceding\fR the character of interest. Mnemonic: move cursor up \fBt\fRo character .IP [cnt]T{chr} 16 .sp 1 Search backwards on the line for the next or "cnt"'th occurrence of the character "chr". The cursor is placed \fBjust preceding\fR the character of interest. .IP "[cnt];" 16 Repeat the last "f", "F", "t" or "T" command. .IP "[cnt]," 16 Repeat the last "f", "F", "t" or "T" command, but in the opposite search direction. This is useful if you overshoot. .IP "[cnt]/[string]/" 16 .br Search forward for the next occurrence of "string". Wrap around at the end of the file does occur. The final \fB\fR is not required. .IP "[cnt]?[string]?" 16 .br Search backwards for the next occurrence of "string". If a count is specified, the count becomes the new window size. Wrap around at the beginning of the file does occur. The final \fB\fR is not required. .IP n 16 Repeat the last /[string]/ or ?[string]? search. Mnemonic: \fBn\fRext occurrence. .IP N 16 Repeat the last /[string]/ or ?[string]? search, but in the reverse direction. .IP ":g/[string]/[editor command]" 16 .sp 1 Using the \fB:\fR syntax it is possible to do global searches ala the standard UNIX "ed" editor. .NH 2 Text Insertion .LP The following commands allow for the insertion of text. All multicharacter text insertions are terminated with an character. The last change can always be \fBundone\fR by typing a \fBu\fR. The text insert in insertion mode can contain newlines. .IP a{text} 16 Insert text immediately following the cursor position. Mnemonic: \fBa\fRppend .IP A{text} 16 Insert text at the end of the current line. Mnemonic: \fBA\fRppend .IP i{text} 16 Insert text immediately preceding the cursor position. Mnemonic: \fBi\fRnsert .IP I{text} 16 Insert text at the beginning of the current line. .IP o{text} 16 Insert a new line after the line on which the cursor appears and insert text there. Mnemonic: \fBo\fRpen new line .IP O{text} 16 Insert a new line preceding the line on which the cursor appears and insert text there. .NH 2 Text Deletion .LP The following commands allow the user to delete text in various ways. All changes can always be \fBundone\fR by typing the \fBu\fR command. .IP "[cnt]x" 16 Delete the character or characters starting at the cursor position. .IP "[cnt]X" 16 Delete the character or characters starting at the character preceding the cursor position. .IP "D" 16 Deletes the remainder of the line starting at the cursor. Mnemonic: \fBD\fRelete the rest of line .IP "[cnt]d{motion}" 16 .br Deletes one or more occurrences of the specified motion. Any motion from sections 4.1 and 4.2 can be used here. The d can be stuttered (e.g. [cnt]dd) to delete cnt lines. .NH 2 Text Replacement .LP The following commands allow the user to simultaneously delete and insert new text. All such actions can be \fBundone\fR by typing \fBu\fR following the command. .IP "r" 16 Replaces the character at the current cursor position with . This is a one character replacement. No is required for termination. Mnemonic: \fBr\fReplace character .IP "R{text}" 16 Starts overlaying the characters on the screen with whatever you type. It does not stop until an is typed. .IP "[cnt]s{text}" 16 Substitute for "cnt" characters beginning at the current cursor position. A "$" will appear at the position in the text where the "cnt"'th character appears so you will know how much you are erasing. Mnemonic: \fBs\fRubstitute .IP "[cnt]S{text}" 16 Substitute for the entire current line (or lines). If no count is given, a "$" appears at the end of the current line. If a count of more than 1 is given, all the lines to be replaced are deleted before the insertion begins. .IP "[cnt]c{motion}{text}" 16 .br Change the specified "motion" by replacing it with the insertion text. A "$" will appear at the end of the last item that is being deleted unless the deletion involves whole lines. Motion's can be any motion from sections 4.1 or 4.2. Stuttering the c (e.g. [cnt]cc) changes cnt lines. .NH 2 Moving Text .LP \fBVi\fR provides a number of ways of moving chunks of text around. There are nine buffers into which each piece of text which is deleted or "yanked" is put in addition to the "undo" buffer. The most recent deletion or yank is in the "undo" buffer and also usually in buffer 1, the next most recent in buffer 2, and so forth. Each new deletion pushes down all the older deletions. Deletions older than 9 disappear. There is also a set of named registers, a-z, into which text can optionally be placed. If any delete or replacement type command is preceded by \fB"\fR, that named buffer will contain the text deleted after the command is executed. For example, \fB"a3dd\fR will delete three lines starting at the current line and put them in buffer \fB"a\fR.* .FS * Referring to an upper case letter as a buffer name (A-Z) is the same as referring to the lower case letter, except that text placed in such a buffer is appended to it instead of replacing it. .FE There are two more basic commands and some variations useful in getting and putting text into a file. .IP ["][cnt]y{motion} 16 .sp 1 Yank the specified item or "cnt" items and put in the "undo" buffer or the specified buffer. The variety of "items" that can be yanked is the same as those that can be deleted with the "d" command or changed with the "c" command. In the same way that "dd" means delete the current line and "cc" means replace the current line, "yy" means yank the current line. .IP ["][cnt]Y 16 Yank the current line or the "cnt" lines starting from the current line. If no buffer is specified, they will go into the "undo" buffer, like any delete would. It is equivalent to "yy". Mnemonic: \fBY\fRank .IP ["]p 16 Put "undo" buffer or the specified buffer down \fBafter\fR the cursor. If whole lines were yanked or deleted into the buffer, then they will be put down on the line following the line the cursor is on. If something else was deleted, like a word or sentence, then it will be inserted immediately following the cursor. Mnemonic: \fBp\fRut buffer .IP It should be noted that text in the named buffers remains there when you start editing a new file with the \fB:e file\fR command. Since this is so, it is possible to copy or delete text from one file and carry it over to another file in the buffers. However, the undo buffer and the ability to undo are lost when changing files. .IP ["]P 16 Put "undo" buffer or the specified buffer down \fBbefore\fR the cursor. If whole lines where yanked or deleted into the buffer, then they will be put down on the line preceding the line the cursor is on. If something else was deleted, like a word or sentence, then it will be inserted immediately preceding the cursor. .IP [cnt]>{motion} 16 The shift operator will right shift all the text from the line on which the cursor is located to the line where the \fBmotion\fR is located. The text is shifted by one \fBshiftwidth\fR. (See section 6.) \fB>>\fR means right shift the current line or lines. .IP [cnt]<{motion} 16 The shift operator will left shift all the text from the line on which the cursor is located to the line where the \fBitem\fR is located. The text is shifted by one \fBshiftwidth\fR. (See section 6.) \fB<<\fR means left shift the current line or lines. Once the line has reached the left margin it is not further affected. .IP [cnt]={motion} 16 Prettyprints the indicated area according to .B lisp conventions. The area should be a lisp s-expression. .NH 2 Miscellaneous Commands .LP \fBVi\fR has a number of miscellaneous commands that are very useful. They are: .IP ZZ 16 This is the normal way to exit from vi. If any changes have been made, the file is written out. Then you are returned to the shell. .IP ^L 16 Redraw the current screen. This is useful if someone "write"s you while you are in "vi" or if for any reason garbage gets onto the screen. .IP ^R 16 On dumb terminals, those not having the "delete line" function (the vt100 is such a terminal), \fBvi\fR saves redrawing the screen when you delete a line by just marking the line with an "@" at the beginning and blanking the line. If you want to actually get rid of the lines marked with "@" and see what the page looks like, typing a ^R will do this. .IP \s+4.\s0 16 "Dot" is a particularly useful command. It repeats the last text modifying command. Therefore you can type a command once and then to another place and repeat it by just typing ".". .IP u 16 Perhaps the most important command in the editor, u undoes the last command that changed the buffer. Mnemonic: \fBu\fRndo .IP U 16 Undo all the text modifying commands performed on the current line since the last time you moved onto it. .IP [cnt]J 16 Join the current line and the following line. The is deleted and the two lines joined, usually with a space between the end of the first line and the beginning of what was the second line. If the first line ended with a "period", then two spaces are inserted. A count joins the next cnt lines. Mnemonic: \fBJ\fRoin lines .IP Q 16 Switch to \fBex\fR editing mode. In this mode \fBvi\fR will behave very much like \fBed\fR. The editor in this mode will operate on single lines normally and will not attempt to keep the "window" up to date. Once in this mode it is also possible to switch to the \fBopen\fR mode of editing. By entering the command \fB[line number]open\fR you enter this mode. It is similar to the normal visual mode except the window is only \fBone\fR line long. Mnemonic: \fBQ\fRuit visual mode .IP ^] 16 An abbreviation for a tag command. The cursor should be positioned at the beginning of a word. That word is taken as a tag name, and the tag with that name is found as if it had been typed in a :tag command. .IP [cnt]!{motion}{UNIX\ cmd} 16 .br Any UNIX filter (e.g. command that reads the standard input and outputs something to the standard output) can be sent a section of the current file and have the output of the command replace the original text. Useful examples are programs like \fBcb\fR, \fBsort\fR, and \fBnroff\fR. For instance, using \fBsort\fR it would be possible to sort a section of the current file into a new list. Using \fB!!\fR means take a line or lines starting at the line the cursor is currently on and pass them to the UNIX command. .B NOTE: To just escape to the shell for one command, use :!{cmd}, see section 5. .IP z{cnt} 16 This resets the current window size to "cnt" lines and redraws the screen. .NH 2 Special Insert Characters .LP There are some characters that have special meanings during insert modes. They are: .IP ^V 16 During inserts, typing a ^V allows you to quote control characters into the file. Any character typed after the ^V will be inserted into the file. .IP [^]^D\ or\ [0]^D 16 <^D> without any argument backs up one \fBshiftwidth\fR. This is necessary to remove indentation that was inserted by the \fBautoindent\fR feature. ^<^D> temporarily removes all the autoindentation, thus placing the cursor at the left margin. On the next line, the previous indent level will be restored. This is useful for putting "labels" at the left margin. 0<^D> says remove all autoindents and stay that way. Thus the cursor moves to the left margin and stays there on successive lines until 's are typed. As with the , the <^D> is only effective before any other "non-autoindent" controlling characters are typed. Mnemonic: \fBD\fRelete a shiftwidth .IP ^W 16 If the cursor is sitting on a word, <^W> moves the cursor back to the beginning of the word, thus erasing the word from the insert. Mnemonic: erase \fBW\fRord .IP 16 The backspace always serves as an erase during insert modes in addition to your normal "erase" character. To insert a into your file, use the <^V> to quote it. .NH 1 \fB:\fR Commands .LP Typing a ":" during command mode causes \fBvi\fR to put the cursor at the bottom on the screen in preparation for a command. In the ":" mode, \fBvi\fR can be given most \fBed\fR commands. It is also from this mode that you exit from \fBvi\fR or switch to different files. All commands of this variety are terminated by a , , or . .IP ":w[!] [file]" 16 Causes \fBvi\fR to write out the current text to the disk. It is written to the file you are editing unless "file" is supplied. If "file" is supplied, the write is directed to that file instead. If that file already exists, \fBvi\fR will not perform the write unless the "!" is supplied indicating you .I really want to destroy the older copy of the file. .IP :q[!] 16 Causes \fBvi\fR to exit. If you have modified the file you are looking at currently and haven't written it out, \fBvi\fR will refuse to exit unless the "!" is supplied. .IP ":e[!] [+[cmd]] [file]" 16 .sp 1 Start editing a new file called "file" or start editing the current file over again. The command ":e!" says "ignore the changes I've made to this file and start over from the beginning". It is useful if you really mess up the file. The optional "+" says instead of starting at the beginning, start at the "end", or, if "cmd" is supplied, execute "cmd" first. Useful cases of this are where cmd is "n" (any integer) which starts at line number n, and "/text", which searches for "text" and starts at the line where it is found. .IP "^^" 16 Switch back to the place you were before your last tag command. If your last tag command stayed within the file, ^^ returns to that tag. If you have no recent tag command, it will return to the same place in the previous file that it was showing when you switched to the current file. .IP ":n[!]" 16 Start editing the next file in the argument list. Since \fBvi\fR can be called with multiple file names, the ":n" command tells it to stop work on the current file and switch to the next file. If the current file was modifies, it has to be written out before the ":n" will work or else the "!" must be supplied, which says discard the changes I made to the current file. .IP ":n[!] file [file file ...]" 16 .sp Replace the current argument list with a new list of files and start editing the first file in this new list. .IP ":r file" 16 Read in a copy of "file" on the line after the cursor. .IP ":r !cmd" 16 Execute the "cmd" and take its output and put it into the file after the current line. .IP ":!cmd" 16 Execute any UNIX shell command. .IP ":ta[!] tag" 16 .B Vi looks in the file named .B tags in the current directory. .B Tags is a file of lines in the format: .sp 1 .ti +8 tag filename \fBvi\fR-search-command .sp 1 If \fBvi\fR finds the tag you specified in the \fB:ta\fR command, it stops editing the current file if necessary and if the current file is up to date on the disk and switches to the file specified and uses the search pattern specified to find the "tagged" item of interest. This is particularly useful when editing multi-file C programs such as the operating system. There is a program called \fBctags\fR which will generate an appropriate \fBtags\fR file for C and f77 programs so that by saying \fB:ta function\fR you will be switched to that function. It could also be useful when editing multi-file documents, though the \fBtags\fR file would have to be generated manually. .NH 1 Special Arrangements for Startup .PP \fBVi\fR takes the value of \fB$TERM\fR and looks up the characteristics of that terminal in the file \fB/etc/termcap\fR. If you don't know \fBvi\fR's name for the terminal you are working on, look in \fB/etc/termcap\fR. .PP When \fBvi\fR starts, it attempts to read the variable EXINIT from your environment.* If that exists, it takes the values in it as the default values for certain of its internal constants. See the section on "Set Values" for further details. If EXINIT doesn't exist you will get all the normal defaults. .FS * On version 6 systems Instead of EXINIT, put the startup commands in the file .exrc in your home directory. .FE .PP Should you inadvertently hang up the phone while inside .B vi , or should the computer crash, all may not be lost. Upon returning to the system, type: .DS vi \-r file .DE This will normally recover the file. If there is more than one temporary file for a specific file name, \fBvi\fR recovers the newest one. You can get an older version by recovering the file more than once. The command "vi -r" without a file name gives you the list of files that were saved in the last system crash (but .I not the file just saved when the phone was hung up). .NH 1 Set Commands .LP \fBVi\fR has a number of internal variables and switches which can be set to achieve special affects. These options come in three forms, those that are switches, which toggle from off to on and back, those that require a numeric value, and those that require an alphanumeric string value. The toggle options are set by a command of the form: .DS :set option .DE and turned off with the command: .DS :set nooption .DE Commands requiring a value are set with a command of the form: .DS :set option=value .DE To display the value of a specific option type: .DS :set option? .DE To display only those that you have changed type: .DS :set .DE and to display the long table of all the settable parameters and their current values type: .DS :set all .DE .PP Most of the options have a long form and an abbreviation. Both are listed in the following table as well as the normal default value. .PP To arrange to have values other than the default used every time you enter .B vi , place the appropriate .B set command in EXINIT in your environment, e.g. .DS EXINIT='set ai aw terse sh=/bin/csh' export EXINIT .DE or .DS setenv EXINIT 'set ai aw terse sh=/bin/csh' .DE for .B sh and .B csh , respectively. These are usually placed in your .profile or .login. If you are running a system without environments (such as version 6) you can place the set command in the file .exrc in your home directory. .IP autoindent\ ai 16 Default: noai Type: toggle .br When in autoindent mode, vi helps you indent code by starting each line in the same column as the preceding line. Tabbing to the right with or <^T> will move this boundary to the right, and it can be moved to the left with <^D>. .IP autoprint\ ap 16 Default: ap Type: toggle .br Causes the current line to be printed after each ex text modifying command. This is not of much interest in the normal \fBvi\fR visual mode. .IP autowrite\ aw 16 Default: noaw type: toggle .br Autowrite causes an automatic write to be done if there are unsaved changes before certain commands which change files or otherwise interact with the outside world. These commands are :!, :tag, :next, :rewind, ^^, and ^]. .IP beautify\ bf 16 Default: nobf Type: toggle .br Causes all control characters except , , and to be discarded. .IP directory\ dir 16 Default: dir=/tmp Type: string .br This is the directory in which \fBvi\fR puts its temporary file. .IP errorbells\ eb 16 Default: noeb Type: toggle .br Error messages are preceded by a . .IP hardtabs\ ht 16 Default: hardtabs=8 Type: numeric .br This option contains the value of hardware tabs in your terminal, or of software tabs expanded by the Unix system. .IP ignorecase\ ic 16 Default: noic Type: toggle .br All upper case characters are mapped to lower case in regular expression matching. .IP lisp 16 Default: nolisp Type: toggle .br Autoindent for \fBlisp\fR code. The commands \fB( ) [[\fR and \fB]]\fR are modified appropriately to affect s-expressions and functions. .IP list 16 Default: nolist Type: toggle .br All printed lines have the and characters displayed visually. .IP magic 16 Default: magic Type: toggle .br Enable the metacharacters for matching. These include \fB. * < > [string] [^string]\fR and \fB[-]\fR. .IP number\ nu 16 Default: nonu Type: toggle .br Each line is displayed with its line number. .IP open 16 Default: open Type: toggle .br When set, prevents entering open or visual modes from ex or edit. Not of interest from vi. .IP optimize\ opt 16 Default: opt Type: toggle .br Basically of use only when using the \fBex\fR capabilities. This option prevents automatic s from taking place, and speeds up output of indented lines, at the expense of losing typeahead on some versions of UNIX. .IP paragraphs\ para 16 Default: para=IPLPPPQPP\ bp Type: string .br Each pair of characters in the string indicate \fBnroff\fR macros which are to be treated as the beginning of a paragraph for the \fB{\fR and \fB}\fR commands. The default string is for the \fB-ms\fR and \fB-mm\fR macros. To indicate one letter \fBnroff\fR macros, such as \fB.P\fR or \fB.H\fR, quote a space in for the second character position. For example: .sp 1 .ti +8 :set paragraphs=P\e bp .sp 1 would cause \fBvi\fR to consider \fB.P\fR and \fB.bp\fR as paragraph delimiters. .IP prompt 16 Default: prompt Type: toggle .br In .B ex command mode the prompt character \fB:\fR will be printed when \fBex\fR is waiting for a command. This is not of interest from vi. .IP redraw 16 Default: noredraw Type: toggle .br On dumb terminals, force the screen to always be up to date, by sending great amounts of output. Useful only at high speeds. .IP report 16 Default: report=5 Type: numeric .br This sets the threshold for the number of lines modified. When more than this number of lines are modified, removed, or yanked, \fBvi\fR will report the number of lines changed at the bottom of the screen. .IP scroll 16 Default: scroll={1/2 window} Type: numeric .br This is the number of lines that the screen scrolls up or down when using the <^U> and <^D> commands. .IP sections 16 Default: sections=SHNHH HU Type: string .br Each two character pair of this string specify \fBnroff\fR macro names which are to be treated as the beginning of a section by the \fB]]\fR and \fB[[\fR commands. The default string is for the \fB-ms\fR and \fB-mm\fR macros. To enter one letter \fBnroff\fR macros, use a quoted space as the second character. See \fBparagraphs\fR for a fuller explanation. .IP shell\ sh 16 Default: sh=from environment SHELL or /bin/sh Type: string .br This is the name of the \fBsh\fR to be used for "escaped" commands. .IP shiftwidth\ sw 16 Default: sw=8 Type: numeric .br This is the number of spaces that a <^T> or <^D> will move over for indenting, and the amount < and > shift by. .IP showmatch\ sm 16 Default: nosm Type: toggle .br When a \fB)\fR or \fB}\fR is typed, show the matching \fB(\fR or \fB{\fR by moving the cursor to it for one second if it is on the current screen. .IP slowopen\ slow 16 Default: terminal dependent Type: toggle .br On terminals that are slow and unintelligent, this option prevents the updating of the screen some of the time to improve speed. .IP tabstop\ ts 16 Default: ts=8 Type: numeric .br s are expanded to boundaries that are multiples of this value. .IP taglength\ tl 16 Default: tl=0 Type: numeric .br If nonzero, tag names are only significant to this many characters. .IP term 16 Default: (from environment \fBTERM\fP, else dumb) Type: string .br This is the terminal and controls the visual displays. It cannot be changed when in "visual" mode, you have to Q to command mode, type a set term command, and do ``vi.'' to get back into visual. Or exit vi, fix $TERM, and reenter. The definitions that drive a particular terminal type are found in the file \fB/etc/termcap\fR. .IP terse 16 Default: terse Type: toggle .br When set, the error diagnostics are short. .IP warn 16 Default: warn Type: toggle .br The user is warned if she/he tries to escape to the shell without writing out the current changes. .IP window 16 Default: window={8 at 600 baud or less, 16 at 1200 baud, and screen size \- 1 at 2400 baud or more} Type: numeric .br This is the number of lines in the window whenever \fBvi\fR must redraw an entire screen. It is useful to make this size smaller if you are on a slow line. .IP w300,\ w1200,\ w9600 .br These set window, but only within the corresponding speed ranges. They are useful in an EXINIT to fine tune window sizes. For example, .DS set w300=4 w1200=12 .DE causes a 4 lines window at speed up to 600 baud, a 12 line window at 1200 baud, and a full screen (the default) at over 1200 baud. .IP wrapscan\ ws 16 Default: ws Type: toggle .br Searches will wrap around the end of the file when is option is set. When it is off, the search will terminate when it reaches the end or the beginning of the file. .IP wrapmargin\ wm 16 Default: wm=0 Type: numeric .br \fBVi\fR will automatically insert a when it finds a natural break point (usually a between words) that occurs within "wm" spaces of the right margin. Therefore with "wm=0" the option is off. Setting it to 10 would mean that any time you are within 10 spaces of the right margin \fBvi\fR would be looking for a or which it could replace with a . This is convenient for people who forget to look at the screen while they type. (In version 3, wrapmargin behaves more like nroff, in that the boundary specified by the distance from the right edge of the screen is taken as the rightmost edge of the area where a break is allowed, instead of the leftmost edge.) .IP writeany\ wa 16 Default: nowa Type: toggle .br \fBVi\fR normally makes a number of checks before it writes out a file. This prevents the user from inadvertently destroying a file.

The characters are presented in their order in the \s-2ASCII\s0 character set: Control characters come first, then most special characters, then the digits, upper and then lower case characters. .PP For each character we tell a meaning it has as a command and any meaning it has during an insert. If it has only meaning as a command, then only this is discussed. Section numbers in parentheses indicate where the character is discussed; a `f' after the section number means that the character is mentioned in a footnote. .iP "^@" 15 Not a command character. If typed as the first character of an insertion it is replaced with the last text inserted, and the insert terminates. Only 128 characters are saved from the last insert; if more characters were inserted the mechanism is not available. A \fB^@\fR cannot be part of the file due to the editor implementation (7.5f). .iP "^A" 15 Unused. .iP "^B" 15 Backward window. A count specifies repetition. Two lines of continuity are kept if possible (2.1, 6.1, 7.2). .iP "^C" 15 Unused. .iP "^D" 15 As a command, scrolls down a half-window of text. A count gives the number of (logical) lines to scroll, and is remembered for future \fB^D\fR and \fB^U\fR commands (2.1, 7.2). During an insert, backtabs over \fIautoindent\fR white space at the beginning of a line (6.6, 7.5); this white space cannot be backspaced over. .iP "^E" 15 Exposes one more line below the current screen in the file, leaving the cursor where it is if possible. (Version 3 only.) .iP "^F" 15 Forward window. A count specifies repetition. Two lines of continuity are kept if possible (2.1, 6.1, 7.2). .iP "^G" 15 Equivalent to \fB:f\fR\s-2CR\s0, printing the current file, whether it has been modified, the current line number and the number of lines in the file, and the percentage of the way through the file that you are. .iP "^H (\fR\s-2BS\s0\fP)" 15 Same as .B "left arrow" . (See .B h ). During an insert, eliminates the last input character, backing over it but not erasing it; it remains so you can see what you typed if you wish to type something only slightly different (3.1, 7.5). .iP "^I\ (\fR\s-2TAB\s0\fP)" 15 Not a command character. When inserted it prints as some number of spaces. When the cursor is at a tab character it rests at the last of the spaces which represent the tab. The spacing of tabstops is controlled by the \fItabstop\fR option (4.1, 6.6). .iP "^J\ (\fR\s-2LF\s0\fP)" 15 Same as .B "down arrow" (see .B j ). .iP "^K" 15 Unused. .iP "^L" 15 The \s-2ASCII\s0 formfeed character, this causes the screen to be cleared and redrawn. This is useful after a transmission error, if characters typed by a program other than the editor scramble the screen, or after output is stopped by an interrupt (5.4, 7.2f). .ne 1i .iP "^M\ (\fR\s-2CR\s0\fP)" 15 A carriage return advances to the next line, at the first non-white position in the line. Given a count, it advances that many lines (2.3). During an insert, a \s-2CR\s0 causes the insert to continue onto another line (3.1). .iP "^N" 15 Same as .B "down arrow" (see .B j ). .iP "^O" 15 Unused. .iP "^P" 15 Same as .B "up arrow" (see .B k ). .iP "^Q" 15 Not a command character. In input mode, .B ^Q quotes the next character, the same as .B ^V , except that some teletype drivers will eat the .B ^Q so that the editor never sees it. .iP "^R" 15 Redraws the current screen, eliminating logical lines not corresponding to physical lines (lines with only a single @ character on them). On hardcopy terminals in \fIopen\fR mode, retypes the current line (5.4, 7.2, 7.8). .iP "^S" 15 Unused. Some teletype drivers use .B ^S to suspend output until .B ^Q is pressed. .iP "^T" 15 Not a command character. During an insert, with \fIautoindent\fR set and at the beginning of the line, inserts \fIshiftwidth\fR white space. .iP "^U" 15 Scrolls the screen up, inverting \fB^D\fR which scrolls down. Counts work as they do for \fB^D\fR, and the previous scroll amount is common to both. On a dumb terminal, \fB^U\fR will often necessitate clearing and redrawing the screen further back in the file (2.1, 7.2). .iP "^V" 15 Not a command character. In input mode, quotes the next character so that it is possible to insert non-printing and special characters into the file (4.2, 7.5). .iP "^W" 15 Not a command character. During an insert, backs up as \fBb\fR would in command mode; the deleted characters remain on the display (see \fB^H\fR) (7.5). .iP "^X" 15 Unused. .iP "^Y" 15 Exposes one more line above the current screen, leaving the cursor where it is if possible. (No mnemonic value for this key; however, it is next to \fB^U\fR which scrolls up a bunch.) (Version 3 only.) .iP "^Z" 15 If supported by the Unix system, stops the editor, exiting to the top level shell. Same as \fB:stop\fP\s-2CR\s0. Otherwise, unused. .iP "^[\ (\fR\s-2ESC\s0\fP)" 15 Cancels a partially formed command, such as a \fBz\fR when no following character has yet been given; terminates inputs on the last line (read by commands such as \fB: /\fR and \fB?\fR); ends insertions of new text into the buffer. If an \s-2ESC\s0 is given when quiescent in command state, the editor rings the bell or flashes the screen. You can thus hit \s-2ESC\s0 if you don't know what is happening till the editor rings the bell. If you don't know if you are in insert mode you can type \s-2ESC\s0\fBa\fR, and then material to be input; the material will be inserted correctly whether or not you were in insert mode when you started (1.5, 3.1, 7.5). .iP "^\e" 15 Unused. .iP "^]" 15 Searches for the word which is after the cursor as a tag. Equivalent to typing \fB:ta\fR, this word, and then a \s-2CR\s0. Mnemonically, this command is ``go right to'' (7.3). .iP "^\(ua" 15 Equivalent to \fB:e #\fR\s-2CR\s0, returning to the previous position in the last edited file, or editing a file which you specified if you got a `No write since last change diagnostic' and do not want to have to type the file name again (7.3). (You have to do a \fB:w\fR before \fB^\(ua\fR will work in this case. If you do not wish to write the file you should do \fB:e!\ #\fR\s-2CR\s0 instead.) .iP "^_" 15 Unused. Reserved as the command character for the Tektronix 4025 and 4027 terminal. .iP "\fR\s-2SPACE\s0\fP" 15 Same as .B "right arrow" (see .B l ). .iP "!" 15 An operator, which processes lines from the buffer with reformatting commands. Follow \fB!\fR with the object to be processed, and then the command name terminated by \s-2CR\s0. Doubling \fB!\fR and preceding it by a count causes count lines to be filtered; otherwise the count is passed on to the object after the \fB!\fR. Thus \fB2!}\fR\fIfmt\fR\s-2CR\s0 reformats the next two paragraphs by running them through the program \fIfmt\fR. If you are working on \s-2LISP\s0, the command \fB!%\fR\fIgrind\fR\s-2CR\s0,* .FS *Both .I fmt and .I grind are Berkeley programs and may not be present at all installations. .FE given at the beginning of a function, will run the text of the function through the \s-2LISP\s0 grinder (6.7, 7.3). To read a file or the output of a command into the buffer use \fB:r\fR (7.3). To simply execute a command use \fB:!\fR (7.3). .tr " .iP  15 Precedes a named buffer specification. There are named buffers \fB1\-9\fR used for saving deleted text and named buffers \fBa\-z\fR into which you can place text (4.3, 6.3) .tr  .iP "#" 15 The macro character which, when followed by a number, will substitute for a function key on terminals without function keys (6.9). In input mode, if this is your erase character, it will delete the last character you typed in input mode, and must be preceded with a \fB\e\fR to insert it, since it normally backs over the last input character you gave. .iP "$" 15 Moves to the end of the current line. If you \fB:se list\fR\s-2CR\s0, then the end of each line will be shown by printing a \fB$\fR after the end of the displayed text in the line. Given a count, advances to the count'th following end of line; thus \fB2$\fR advances to the end of the following line. .iP "%" 15 Moves to the parenthesis or brace \fB{ }\fR which balances the parenthesis or brace at the current cursor position. .iP "&" 15 A synonym for \fB:&\fR\s-2CR\s0, by analogy with the .I ex .B & command. .iP "\(aa" 15 When followed by a \fB\(aa\fR returns to the previous context at the beginning of a line. The previous context is set whenever the current line is moved in a non-relative way. When followed by a letter \fBa\fR\-\fBz\fR, returns to the line which was marked with this letter with a \fBm\fR command, at the first non-white character in the line. (2.2, 5.3). When used with an operator such as \fBd\fR, the operation takes place over complete lines; if you use \fB\(ga\fR, the operation takes place from the exact marked place to the current cursor position within the line. .iP "(" 15 Retreats to the beginning of a sentence, or to the beginning of a \s-2LISP\s0 s-expression if the \fIlisp\fR option is set. A sentence ends at a \fB. !\fR or \fB?\fR which is followed by either the end of a line or by two spaces. Any number of closing \fB) ] "\fR and \fB\(aa\fR characters may appear after the \fB. !\fR or \fB?\fR, and before the spaces or end of line. Sentences also begin at paragraph and section boundaries (see \fB{\fR and \fB[[\fR below). A count advances that many sentences (4.2, 6.8). .iP ")" 15 Advances to the beginning of a sentence. A count repeats the effect. See \fB(\fR above for the definition of a sentence (4.2, 6.8). .iP "*" 15 Unused. .iP "+" 15 Same as \s-2CR\s0 when used as a command. .iP "," 15 Reverse of the last \fBf F t\fR or \fBT\fR command, looking the other way in the current line. Especially useful after hitting too many \fB;\fR characters. A count repeats the search. .iP "\-" 15 Retreats to the previous line at the first non-white character. This is the inverse of \fB+\fR and \s-2RETURN\s0. If the line moved to is not on the screen, the screen is scrolled, or cleared and redrawn if this is not possible. If a large amount of scrolling would be required the screen is also cleared and redrawn, with the current line at the center (2.3). .iP "\&." 15 Repeats the last command which changed the buffer. Especially useful when deleting words or lines; you can delete some words/lines and then hit \fB.\fR to delete more and more words/lines. Given a count, it passes it on to the command being repeated. Thus after a \fB2dw\fR, \fB3.\fR deletes three words (3.3, 6.3, 7.2, 7.4). .iP "/" 15 Reads a string from the last line on the screen, and scans forward for the next occurrence of this string. The normal input editing sequences may be used during the input on the bottom line; an returns to command state without ever searching. The search begins when you hit \s-2CR\s0 to terminate the pattern; the cursor moves to the beginning of the last line to indicate that the search is in progress; the search may then be terminated with a \s-2DEL\s0 or \s-2RUB\s0, or by backspacing when at the beginning of the bottom line, returning the cursor to its initial position. Searches normally wrap end-around to find a string anywhere in the buffer. .IP When used with an operator the enclosed region is normally affected. By mentioning an offset from the line matched by the pattern you can force whole lines to be affected. To do this give a pattern with a closing a closing \fB/\fR and then an offset \fB+\fR\fIn\fR or \fB\-\fR\fIn\fR. .IP To include the character \fB/\fR in the search string, you must escape it with a preceding \fB\e\fR. A \fB\(ua\fR at the beginning of the pattern forces the match to occur at the beginning of a line only; this speeds the search. A \fB$\fR at the end of the pattern forces the match to occur at the end of a line only. More extended pattern matching is available, see section 7.4; unless you set \fBnomagic\fR in your \fI\&.exrc\fR file you will have to preceed the characters \fB. [ *\fR and \fB~\fR in the search pattern with a \fB\e\fR to get them to work as you would naively expect (1.5, 2,2, 6.1, 7.2, 7.4). .iP "0" 15 Moves to the first character on the current line. Also used, in forming numbers, after an initial \fB1\fR\-\fB9\fR. .iP "1\-9" 15 Used to form numeric arguments to commands (2.3, 7.2). .iP ":" 15 A prefix to a set of commands for file and option manipulation and escapes to the system. Input is given on the bottom line and terminated with an \s-2CR\s0, and the command then executed. You can return to where you were by hitting \s-2DEL\s0 or \s-2RUB\s0 if you hit \fB:\fR accidentally (see primarily 6.2 and 7.3). .iP ";" 15 Repeats the last single character find which used \fBf F t\fR or \fBT\fR. A count iterates the basic scan (4.1). .iP "<" 15 An operator which shifts lines left one \fIshiftwidth\fR, normally 8 spaces. Like all operators, affects lines when repeated, as in \fB<<\fR. Counts are passed through to the basic object, thus \fB3<<\fR shifts three lines (6.6, 7.2). .iP "=" 15 Reindents line for \s-2LISP\s0, as though they were typed in with \fIlisp\fR and \fIautoindent\fR set (6.8). .iP ">" 15 An operator which shifts lines right one \fIshiftwidth\fR, normally 8 spaces. Affects lines when repeated as in \fB>>\fR. Counts repeat the basic object (6.6, 7.2). .iP "?" 15 Scans backwards, the opposite of \fB/\fR. See the \fB/\fR description above for details on scanning (2.2, 6.1, 7.4). .iP "@" 15 A macro character (6.9). If this is your kill character, you must escape it with a \e to type it in during input mode, as it normally backs over the input you have given on the current line (3.1, 3.4, 7.5). .iP "A" 15 Appends at the end of line, a synonym for \fB$a\fR (7.2). .iP "B" 15 Backs up a word, where words are composed of non-blank sequences, placing the cursor at the beginning of the word. A count repeats the effect (2.4). .iP "C" 15 Changes the rest of the text on the current line; a synonym for \fBc$\fR. .iP "D" 15 Deletes the rest of the text on the current line; a synonym for \fBd$\fR. .iP "E" 15 Moves forward to the end of a word, defined as blanks and non-blanks, like \fBB\fR and \fBW\fR. A count repeats the effect. .iP "F" 15 Finds a single following character, backwards in the current line. A count repeats this search that many times (4.1). .iP "G" 15 Goes to the line number given as preceding argument, or the end of the file if no preceding count is given. The screen is redrawn with the new current line in the center if necessary (7.2). .iP "H" 15 .B "Home arrow" . Homes the cursor to the top line on the screen. If a count is given, then the cursor is moved to the count'th line on the screen. In any case the cursor is moved to the first non-white character on the line. If used as the target of an operator, full lines are affected (2.3, 3.2). .iP "I" 15 Inserts at the beginning of a line; a synonym for \fB\(uai\fR. .iP "J" 15 Joins together lines, supplying appropriate white space: one space between words, two spaces after a \fB.\fR, and no spaces at all if the first character of the joined on line is \fB)\fR. A count causes that many lines to be joined rather than the default two (6.5, 7.1f). .iP "K" 15 Unused. .iP "L" 15 Moves the cursor to the first non-white character of the last line on the screen. With a count, to the first non-white of the count'th line from the bottom. Operators affect whole lines when used with \fBL\fR (2.3). .iP "M" 15 Moves the cursor to the middle line on the screen, at the first non-white position on the line (2.3). .iP "N" 15 Scans for the next match of the last pattern given to \fB/\fR or \fB?\fR, but in the reverse direction; this is the reverse of \fBn\fR. .iP "O" 15 Opens a new line above the current line and inputs text there up to an \s-2ESC\s0. A count can be used on dumb terminals to specify a number of lines to be opened; this is generally obsolete, as the \fIslowopen\fR option works better (3.1). .iP "P" 15 Puts the last deleted text back before/above the cursor. The text goes back as whole lines above the cursor if it was deleted as whole lines. Otherwise the text is inserted between the characters before and at the cursor. May be preceded by a named buffer specification \fB"\fR\fIx\fR to retrieve the contents of the buffer; buffers \fB1\fR\-\fB9\fR contain deleted material, buffers \fBa\fR\-\fBz\fR are available for general use (6.3). .iP "Q" 15 Quits from \fIvi\fR to \fIex\fR command mode. In this mode, whole lines form commands, ending with a \s-2RETURN\s0. You can give all the \fB:\fR commands; the editor supplies the \fB:\fR as a prompt (7.7). .iP "R" 15 Replaces characters on the screen with characters you type (overlay fashion). Terminates with an \s-2ESC\s0. .iP "S" 15 Changes whole lines, a synonym for \fBcc\fR. A count substitutes for that many lines. The lines are saved in the numeric buffers, and erased on the screen before the substitution begins. .iP "T" 15 Takes a single following character, locates the character before the cursor in the current line, and places the cursor just after that character. A count repeats the effect. Most useful with operators such as \fBd\fR (4.1). .iP "U" 15 Restores the current line to its state before you started changing it (3.5). .iP "V" 15 Unused. .iP "W" 15 Moves forward to the beginning of a word in the current line, where words are defined as sequences of blank/non-blank characters. A count repeats the effect (2.4). .iP "X" 15 Deletes the character before the cursor. A count repeats the effect, but only characters on the current line are deleted. .iP "Y" 15 Yanks a copy of the current line into the unnamed buffer, to be put back by a later \fBp\fR or \fBP\fR; a very useful synonym for \fByy\fR. A count yanks that many lines. May be preceded by a buffer name to put lines in that buffer (7.4). .iP "ZZ" 15 Exits the editor. (Same as \fB:x\fP\s-2CR\s0.) If any changes have been made, the buffer is written out to the current file. Then the editor quits. .iP "[[" 15 Backs up to the previous section boundary. A section begins at each macro in the \fIsections\fR option, normally a `.NH' or `.SH' and also at lines which which start with a formfeed \fB^L\fR. Lines beginning with \fB{\fR also stop \fB[[\fR; this makes it useful for looking backwards, a function at a time, in C programs. If the option \fIlisp\fR is set, stops at each \fB(\fR at the beginning of a line, and is thus useful for moving backwards at the top level \s-2LISP\s0 objects. (4.2, 6.1, 6.6, 7.2). .iP "\e" 15 Unused. .iP "]]" 15 Forward to a section boundary, see \fB[[\fR for a definition (4.2, 6.1, 6.6, 7.2). .iP "\(ua" 15 Moves to the first non-white position on the current line (4.4). .iP "_" 15 Unused. .iP "\(ga" 15 When followed by a \fB\(ga\fR returns to the previous context. The previous context is set whenever the current line is moved in a non-relative way. When followed by a letter \fBa\fR\-\fBz\fR, returns to the position which was marked with this letter with a \fBm\fR command. When used with an operator such as \fBd\fR, the operation takes place from the exact marked place to the current position within the line; if you use \fB\(aa\fR, the operation takes place over complete lines (2.2, 5.3). .iP "a" 15 Appends arbitrary text after the current cursor position; the insert can continue onto multiple lines by using \s-2RETURN\s0 within the insert. A count causes the inserted text to be replicated, but only if the inserted text is all on one line. The insertion terminates with an \s-2ESC\s0 (3.1, 7.2). .iP "b" 15 Backs up to the beginning of a word in the current line. A word is a sequence of alphanumerics, or a sequence of special characters. A count repeats the effect (2.4). .iP "c" 15 An operator which changes the following object, replacing it with the following input text up to an \s-2ESC\s0. If more than part of a single line is affected, the text which is changed away is saved in the numeric named buffers. If only part of the current line is affected, then the last character to be changed away is marked with a \fB$\fR. A count causes that many objects to be affected, thus both \fB3c)\fR and \fBc3)\fR change the following three sentences (7.4). .iP "d" 15 An operator which deletes the following object. If more than part of a line is affected, the text is saved in the numeric buffers. A count causes that many objects to be affected; thus \fB3dw\fR is the same as \fBd3w\fR (3.3, 3.4, 4.1, 7.4). .iP "e" 15 Advances to the end of the next word, defined as for \fBb\fR and \fBw\fR. A count repeats the effect (2.4, 3.1). .iP "f" 15 Finds the first instance of the next character following the cursor on the current line. A count repeats the find (4.1). .iP "g" 15 Unused. .sp Arrow keys .B h , .B j , .B k , .B l , and .B H . .iP "h" 15 .B "Left arrow" . Moves the cursor one character to the left. Like the other arrow keys, either .B h , the .B "left arrow" key, or one of the synonyms (\fB^H\fP) has the same effect. On v2 editors, arrow keys on certain kinds of terminals (those which send escape sequences, such as vt52, c100, or hp) cannot be used. A count repeats the effect (3.1, 7.5). .iP "i" 15 Inserts text before the cursor, otherwise like \fBa\fR (7.2). .iP "j" 15 .B "Down arrow" . Moves the cursor one line down in the same column. If the position does not exist, .I vi comes as close as possible to the same column. Synonyms include .B ^J (linefeed) and .B ^N . .iP "k" 15 .B "Up arrow" . Moves the cursor one line up. .B ^P is a synonym. .iP "l" 15 .B "Right arrow" . Moves the cursor one character to the right. \s-2SPACE\s0 is a synonym. .iP "m" 15 Marks the current position of the cursor in the mark register which is specified by the next character \fBa\fR\-\fBz\fR. Return to this position or use with an operator using \fB\(ga\fR or \fB\(aa\fR (5.3). .iP "n" 15 Repeats the last \fB/\fR or \fB?\fR scanning commands (2.2). .iP "o" 15 Opens new lines below the current line; otherwise like \fBO\fR (3.1). .iP "p" 15 Puts text after/below the cursor; otherwise like \fBP\fR (6.3). .iP "q" 15 Unused. .iP "r" 15 Replaces the single character at the cursor with a single character you type. The new character may be a \s-2RETURN\s0; this is the easiest way to split lines. A count replaces each of the following count characters with the single character given; see \fBR\fR above which is the more usually useful iteration of \fBr\fR (3.2). .iP "s" 15 Changes the single character under the cursor to the text which follows up to an \s-2ESC\s0; given a count, that many characters from the current line are changed. The last character to be changed is marked with \fB$\fR as in \fBc\fR (3.2). .iP "t" 15 Advances the cursor upto the character before the next character typed. Most useful with operators such as \fBd\fR and \fBc\fR to delete the characters up to a following character. You can use \fB.\fR to delete more if this doesn't delete enough the first time (4.1). .iP "u" 15 Undoes the last change made to the current buffer. If repeated, will alternate between these two states, thus is its own inverse. When used after an insert which inserted text on more than one line, the lines are saved in the numeric named buffers (3.5). .iP "v" 15 Unused. .iP "w" 15 Advances to the beginning of the next word, as defined by \fBb\fR (2.4). .iP "x" 15 Deletes the single character under the cursor. With a count deletes deletes that many characters forward from the cursor position, but only on the current line (6.5). .iP "y" 15 An operator, yanks the following object into the unnamed temporary buffer. If preceded by a named buffer specification, \fB"\fR\fIx\fR, the text is placed in that buffer also. Text can be recovered by a later \fBp\fR or \fBP\fR (7.4). .iP "z" 15 Redraws the screen with the current line placed as specified by the following character: \s-2RETURN\s0 specifies the top of the screen, \fB.\fR the center of the screen, and \fB\-\fR at the bottom of the screen. A count may be given after the \fBz\fR and before the following character to specify the new screen size for the redraw. A count before the \fBz\fR gives the number of the line to place in the center of the screen instead of the default current line. (5.4) .iP "{" 15 Retreats to the beginning of the beginning of the preceding paragraph. A paragraph begins at each macro in the \fIparagraphs\fR option, normally `.IP', `.LP', `.PP', `.QP' and `.bp'.

When using .I vi the screen of your terminal acts as a window into the file which you are editing. Changes which you make to the file are reflected in what you see. .PP Using .I vi you can insert new text any place in the file quite easily. Most of the commands to .I vi move the cursor around in the file. There are commands to move the cursor forward and backward in units of characters, words, sentences and paragraphs. A small set of operators, like .B d for delete and .B c for change, are combined with the motion commands to form operations such as delete word or change paragraph, in a simple and natural way. This regularity and the mnemonic assignment of commands to keys makes the editor command set easy to remember and to use. .PP .I Vi will work on a large number of display terminals, and new terminals are easily driven after editing a terminal description file. While it is advantageous to have an intelligent terminal which can locally insert and delete lines and characters from the display, the editor will function quite well on dumb terminals over slow phone lines. The editor makes allowance for the low bandwidth in these situations and uses smaller window sizes and different display updating algorithms to make best use of the limited speed available. .PP It is also possible to use the command set of .I vi on hardcopy terminals, storage tubes and ``glass tty's'' using a one line editing window; thus .I vi's command set is available on all terminals. The full command set of the more traditional, line oriented editor .I ex is available within .I vi; it is quite simple to switch between the two modes of editing. .AE .NH 1 Getting started .PP .FS The financial support of an \s-2IBM\s0 Graduate Fellowship and the National Science Foundation under grants MCS74-07644-A03 and MCS78-07291 is gratefully acknowledged. .FE This document provides a quick introduction to .I vi. (Pronounced \fIvee-eye\fP.) You should be running .I vi on a file you are familiar with while you are reading this. The first part of this document (sections 1 through 5) describes the basics of using .I vi. Some topics of special interest are presented in section 6, and some nitty-gritty details of how the editor functions are saved for section 7 to avoid cluttering the presentation here. .PP There is also a short appendix here, which gives for each character the special meanings which this character has in \fIvi\fR. Attached to this document should be a quick reference card. This card summarizes the commands of .I vi in a very compact format. You should have the card handy while you are learning .I vi. .NH 2 Specifying terminal type .PP Before you can start .I vi you must tell the system what kind of terminal you are using. Here is a (necessarily incomplete) list of terminal type codes. If your terminal does not appear here, you should consult with one of the staff members on your system to find out the code for your terminal. If your terminal does not have a code, one can be assigned and a description for the terminal can be created. .LP .TS center; ab ab ab a a a.

The code used by the system for this terminal is `2621'. In this case you can use one of the following commands to tell the system the type of your terminal: .DS % \fBsetenv TERM\fP 2621 .DE This command works with the .I csh shell. If you are using the standard Bourne shell .I sh then you should give the commands .DS $ \fBTERM=\fP2621 $ \fBexport TERM\fP .DE .PP If you want to arrange to have your terminal type set up automatically when you log in, you can use the .I tset program. If you dial in on a .I mime , but often use hardwired ports, a typical line for your .I .login file (if you use csh) would be .DS \fBsetenv TERM \(gatset\fP \- \-d mime\(ga .DE or for your .I .profile file (if you use sh) .DS \fBTERM=\(gatse\fPt \- \-d mime\(ga .DE .I Tset knows which terminals are hardwired to each port and needs only to be told that when you dial in you are probably on a .I mime . .I Tset is usually used to change the erase and kill characters, too. .NH 2 Editing a file .PP After telling the system which kind of terminal you have, you should make a copy of a file you are familiar with, and run .I vi on this file, giving the command .DS % \fBvi\fR \fIname\fR .DE replacing \fIname\fR with the name of the copy file you just created. The screen should clear and the text of your file should appear on the screen. If something else happens refer to the footnote.\*(dd .FS \*(dd If you gave the system an incorrect terminal type code then the editor may have just made a mess out of your screen. This happens when it sends control codes for one kind of terminal to some other kind of terminal. In this case hit the keys \fB:q\fR (colon and the q key) and then hit the \s-2RETURN\s0 key. This should get you back to the command level interpreter. Figure out what you did wrong (ask someone else if necessary) and try again. Another thing which can go wrong is that you typed the wrong file name and the editor just printed an error diagnostic. In this case you should follow the above procedure for getting out of the editor, and try again this time spelling the file name correctly. If the editor doesn't seem to respond to the commands which you type here, try sending an interrupt to it by hitting the \s-2DEL\s0 or \s-2RUB\s0 key on your terminal, and then hitting the \fB:q\fR command again followed by a carriage return. .sp .FE .NH 2 The editor's copy: the buffer .PP The editor does not directly modify the file which you are editing. Rather, the editor makes a copy of this file, in a place called the .I buffer, and remembers the file's name. You do not affect the contents of the file unless and until you write the changes you make back into the original file. .NH 2 Notational conventions .PP In our examples, input which must be typed as is will be presented in \fBbold face\fR. Text which should be replaced with appropriate input will be given in \fIitalics\fR. We will represent special characters in \s-2SMALL CAPITALS\s0. .NH 2 Arrow keys .PP The editor command set is independent of the terminal you are using. On most terminals with cursor positioning keys, these keys will also work within the editor. If you don't have cursor positioning keys, or even if you do, you can use the \fBh j k\fR and \fBl\fR keys as cursor positioning keys (these are labelled with arrows on an .I adm3a).* .PP (Particular note for the HP2621: on this terminal the function keys must be \fIshifted\fR (ick) to send to the machine, otherwise they only act locally. Unshifted use will leave the cursor positioned incorrectly.) .FS * As we will see later, .I h moves back to the left (like control-h which is a backspace), .I j moves down (in the same column), .I k moves up (in the same column), and .I l moves to the right. .FE .NH 2 Special characters: \s-2ESC\s0, \s-2CR\s0 and \s-2DEL\s0 .PP Several of these special characters are very important, so be sure to find them right now. Look on your keyboard for a key labelled \s-2ESC\s0 or \s-2ALT\s0. It should be near the upper left corner of your terminal. Try hitting this key a few times. The editor will ring the bell to indicate that it is in a quiescent state.\*(dd .FS \*(dd On smart terminals where it is possible, the editor will quietly flash the screen rather than ringing the bell. .FE Partially formed commands are cancelled by \s-2ESC\s0, and when you insert text in the file you end the text insertion with \s-2ESC\s0. This key is a fairly harmless one to hit, so you can just hit it if you don't know what is going on until the editor rings the bell. .PP The \s-2CR\s0 or \s-2RETURN\s0 key is important because it is used to terminate certain commands. It is usually at the right side of the keyboard, and is the same command used at the end of each shell command. .PP Another very useful key is the \s-2DEL\s0 or \s-2RUB\s0 key, which generates an interrupt, telling the editor to stop what it is doing. It is a forceful way of making the editor listen to you, or to return it to the quiescent state if you don't know or don't like what is going on. Try hitting the `/' key on your terminal. This key is used when you want to specify a string to be searched for. The cursor should now be positioned at the bottom line of the terminal after a `/' printed as a prompt. You can get the cursor back to the current position by hitting the \s-2DEL\s0 or \s-2RUB\s0 key; try this now.* .FS * Backspacing over the `/' will also cancel the search. .FE From now on we will simply refer to hitting the \s-2DEL\s0 or \s-2RUB\s0 key as ``sending an interrupt.''** .FS ** On some systems, this interruptibility comes at a price: you cannot type ahead when the editor is computing with the cursor on the bottom line. .FE .PP The editor often echoes your commands on the last line of the terminal. If the cursor is on the first position of this last line, then the editor is performing a computation, such as computing a new position in the file after a search or running a command to reformat part of the buffer. When this is happening you can stop the editor by sending an interrupt. .NH 2 Getting out of the editor .PP After you have worked with this introduction for a while, and you wish to do something else, you can give the command \fBZZ\fP to the editor. This will write the contents of the editor's buffer back into the file you are editing, if you made any changes, and then quit from the editor. You can also end an editor session by giving the command \fB:q!\fR\s-2CR\s0;\*(dg .FS \*(dg All commands which read from the last display line can also be terminated with a \s-2ESC\s0 as well as an \s-2CR\s0. .FE this is a dangerous but occasionally essential command which ends the editor session and discards all your changes. You need to know about this command in case you change the editor's copy of a file you wish only to look at. Be very careful not to give this command when you really want to save the changes you have made. .NH 1 Moving around in the file .NH 2 Scrolling and paging .PP The editor has a number of commands for moving around in the file. The most useful of these is generated by hitting the control and D keys at the same time, a control-D or `^D'. We will use this two character notation for referring to these control keys from now on. You may have a key labelled `^' on your terminal. This key will be represented as `\(ua' in this document; `^' is exclusively used as part of the `^x' notation for control characters.\*(dd .FS \*(dd If you don't have a `^' key on your terminal then there is probably a key labelled `\(ua'; in any case these characters are one and the same. .FE .PP As you know now if you tried hitting \fB^D\fR, this command scrolls down in the file. The \fBD\fR thus stands for down. Many editor commands are mnemonic and this makes them much easier to remember. For instance the command to scroll up is \fB^U\fR. Many dumb terminals can't scroll up at all, in which case hitting \fB^U\fR clears the screen and refreshes it with a line which is farther back in the file at the top. .PP If you want to see more of the file below where you are, you can hit \fB^E\fR to expose one more line at the bottom of the screen, leaving the cursor where it is. The command \fB^Y\fR (which is hopelessly non-mnemonic, but next to \fB^U\fR on the keyboard) exposes one more line at the top of the screen. .PP There are other ways to move around in the file; the keys \fB^F\fR and \fB^B\fR move forward and backward a page, keeping a couple of lines of continuity between screens so that it is possible to read through a file using these rather than \fB^D\fR and \fB^U\fR if you wish. .PP Notice the difference between scrolling and paging. If you are trying to read the text in a file, hitting \fB^F\fR to move forward a page will leave you only a little context to look back at. Scrolling on the other hand leaves more context, and happens more smoothly. You can continue to read the text as scrolling is taking place. .NH 2 Searching, goto, and previous context .PP Another way to position yourself in the file is by giving the editor a string to search for. Type the character \fB/\fR followed by a string of characters terminated by \s-2CR\s0. The editor will position the cursor at the next occurrence of this string. Try hitting \fBn\fR to then go to the next occurrence of this string. The character \fB?\fR will search backwards from where you are, and is otherwise like \fB/\fR.\*(dg .FS \*(dg These searches will normally wrap around the end of the file, and thus find the string even if it is not on a line in the direction you search provided it is anywhere else in the file. You can disable this wraparound in scans by giving the command \fB:se nowrapscan\fR\s-2CR\s0, or more briefly \fB:se nows\fR\s-2CR\s0. .FE .PP If the search string you give the editor is not present in the file the editor will print a diagnostic on the last line of the screen, and the cursor will be returned to its initial position. .PP If you wish the search to match only at the beginning of a line, begin the search string with an \fB\(ua\fR. To match only at the end of a line, end the search string with a \fB$\fR. Thus \fB/\(uasearch\fR\s-2CR\s0 will search for the word `search' at the beginning of a line, and \fB/last$\fR\s-2CR\s0 searches for the word `last' at the end of a line.* .FS *Actually, the string you give to search for here can be a .I "regular expression" in the sense of the editors .I ex (1) and .I ed (1). If you don't wish to learn about this yet, you can disable this more general facility by doing \fB:se\ nomagic\fR\s-2CR\s0; by putting this command in EXINIT in your environment, you can have this always be in effect (more about .I EXINIT later.) .FE .PP The command \fBG\fR, when preceded by a number will position the cursor at that line in the file. Thus \fB1G\fR will move the cursor to the first line of the file. If you give \fBG\fR no count, then it moves to the end of the file. .PP If you are near the end of the file, and the last line is not at the bottom of the screen, the editor will place only the character `~' on each remaining line. This indicates that the last line in the file is on the screen; that is, the `~' lines are past the end of the file. .PP You can find out the state of the file you are editing by typing a \fB^G\fR. The editor will show you the name of the file you are editing, the number of the current line, the number of lines in the buffer, and the percentage of the way through the buffer which you are. Try doing this now, and remember the number of the line you are on. Give a \fBG\fR command to get to the end and then another \fBG\fR command to get back where you were. .PP You can also get back to a previous position by using the command \fB\(ga\(ga\fR (two back quotes). This is often more convenient than \fBG\fR because it requires no advance preparation. Try giving a \fBG\fR or a search with \fB/\fR or \fB?\fR and then a \fB\(ga\(ga\fR to get back to where you were. If you accidentally hit \fBn\fR or any command which moves you far away from a context of interest, you can quickly get back by hitting \fB\(ga\(ga\fR. .NH 2 Moving around on the screen .PP Now try just moving the cursor around on the screen. If your terminal has arrow keys (4 or 5 keys with arrows going in each direction) try them and convince yourself that they work. If you don't have working arrow keys, you can always use .B h , .B j , .B k , and .B l . Experienced users of .I vi prefer these keys to arrow keys, because they are usually right underneath their fingers. .PP Hit the \fB+\fR key. Each time you do, notice that the cursor advances to the next line in the file, at the first non-white position on the line. The \fB\-\fR key is like \fB+\fR but goes the other way. .PP These are very common keys for moving up and down lines in the file. Notice that if you go off the bottom or top with these keys then the screen will scroll down (and up if possible) to bring a line at a time into view. The \s-2RETURN\s0 key has the same effect as the \fB+\fR key. .PP .I Vi also has commands to take you to the top, middle and bottom of the screen. \fBH\fR will take you to the top (home) line on the screen. Try preceding it with a number as in \fB3H\fR. This will take you to the third line on the screen. Many .I vi commands take preceding numbers and do interesting things with them. Try \fBM\fR, which takes you to the middle line on the screen, and \fBL\fR, which takes you to the last line on the screen. \fBL\fR also takes counts, thus \fB5L\fR will take you to the fifth line from the bottom. .NH 2 Moving within a line .PP Now try picking a word on some line on the screen, not the first word on the line. move the cursor using \s-2RETURN\s0 and \fB\-\fR to be on the line where the word is. Try hitting the \fBw\fR key. This will advance the cursor to the next word on the line. Try hitting the \fBb\fR key to back up words in the line. Also try the \fBe\fR key which advances you to the end of the current word rather than to the beginning of the next word. Also try \s-2SPACE\s0 (the space bar) which moves right one character and the \s-2BS\s0 (backspace or \fB^H\fR) key which moves left one character. The key \fBh\fR works as \fB^H\fR does and is useful if you don't have a \s-2BS\s0 key. (Also, as noted just above, \fBl\fR will move to the right.) .PP If the line had punctuation in it you may have noticed that that the \fBw\fR and \fBb\fR keys stopped at each group of punctuation. You can also go back and forwards words without stopping at punctuation by using \fBW\fR and \fBB\fR rather than the lower case equivalents. Think of these as bigger words. Try these on a few lines with punctuation to see how they differ from the lower case \fBw\fR and \fBb\fR. .PP The word keys wrap around the end of line, rather than stopping at the end. Try moving to a word on a line below where you are by repeatedly hitting \fBw\fR. .NH 2 Summary .IP .TS lw(.50i)b a. \fR\s-2SPACE\s0\fP advance the cursor one position ^B backwards to previous page ^D scrolls down in the file ^E exposes another line at the bottom ^F forward to next page ^G tell what is going on ^H backspace the cursor ^N next line, same column ^P previous line, same column ^U scrolls up in the file ^Y exposes another line at the top + next line, at the beginning \- previous line, at the beginning / scan for a following string forwards ? scan backwards B back a word, ignoring punctuation G go to specified line, last default H home screen line M middle screen line L last screen line W forward a word, ignoring punctuation b back a word e end of current word n scan for next instance of \fB/\fR or \fB?\fR pattern w word after this word .TE .NH 2 View .PP If you want to use the editor to look at a file, rather than to make changes, invoke it as .I view instead of .I vi . This will set the .I readonly option which will prevent you from accidently overwriting the file. .sp .NH 1 Making simple changes .NH 2 Inserting .PP One of the most useful commands is the \fBi\fR (insert) command. After you type \fBi\fR, everything you type until you hit \s-2ESC\s0 is inserted into the file. Try this now; position yourself to some word in the file and try inserting text before this word. If you are on an dumb terminal it will seem, for a minute, that some of the characters in your line have been overwritten, but they will reappear when you hit \s-2ESC\s0. .PP Now try finding a word which can, but does not, end in an `s'. Position yourself at this word and type \fBe\fR (move to end of word), then \fBa\fR for append and then `s\s-2ESC\s0' to terminate the textual insert. This sequence of commands can be used to easily pluralize a word. .PP Try inserting and appending a few times to make sure you understand how this works; \fBi\fR placing text to the left of the cursor, \fBa\fR to the right. .PP It is often the case that you want to add new lines to the file you are editing, before or after some specific line in the file. Find a line where this makes sense and then give the command \fBo\fR to create a new line after the line you are on, or the command \fBO\fR to create a new line before the line you are on. After you create a new line in this way, text you type up to an \s-2ESC\s0 is inserted on the new line. .PP Many related editor commands are invoked by the same letter key and differ only in that one is given by a lower case key and the other is given by an upper case key. In these cases, the upper case key often differs from the lower case key in its sense of direction, with the upper case key working backward and/or up, while the lower case key moves forward and/or down. .PP Whenever you are typing in text, you can give many lines of input or just a few characters. To type in more than one line of text, hit a \s-2RETURN\s0 at the middle of your input. A new line will be created for text, and you can continue to type. If you are on a slow and dumb terminal the editor may choose to wait to redraw the tail of the screen, and will let you type over the existing screen lines. This avoids the lengthy delay which would occur if the editor attempted to keep the tail of the screen always up to date. The tail of the screen will be fixed up, and the missing lines will reappear, when you hit \s-2ESC\s0. .PP While you are inserting new text, you can use the characters you normally use at the system command level (usually \fB^H\fR or \fB#\fR) to backspace over the last character which you typed, and the character which you use to kill input lines (usually \fB@\fR, \fB^X\fR, or \fB^U\fR) to erase the input you have typed on the current line.\*(dg .FS \*(dg In fact, the character \fB^H\fR (backspace) always works to erase the last input character here, regardless of what your erase character is. .FE The character \fB^W\fR will erase a whole word and leave you after the space after the previous word; it is useful for quickly backing up in an insert. .PP Notice that when you backspace during an insertion the characters you backspace over are not erased; the cursor moves backwards, and the characters remain on the display. This is often useful if you are planning to type in something similar. In any case the characters disappear when when you hit \s-2ESC\s0; if you want to get rid of them immediately, hit an \s-2ESC\s0 and then \fBa\fR again. .PP Notice also that you can't erase characters which you didn't insert, and that you can't backspace around the end of a line. If you need to back up to the previous line to make a correction, just hit \s-2ESC\s0 and move the cursor back to the previous line. After making the correction you can return to where you were and use the insert or append command again. .sp .5 .NH 2 Making small corrections .PP You can make small corrections in existing text quite easily. Find a single character which is wrong or just pick any character. Use the arrow keys to find the character, or get near the character with the word motion keys and then either backspace (hit the \s-2BS\s0 key or \fB^H\fR or even just \fBh\fR) or \s-2SPACE\s0 (using the space bar) until the cursor is on the character which is wrong. If the character is not needed then hit the \fBx\fP key; this deletes the character from the file. It is analogous to the way you \fBx\fP out characters when you make mistakes on a typewriter (except it's not as messy). .PP If the character is incorrect, you can replace it with the correct character by giving the command \fBr\fR\fIc\fR, where \fIc\fR is replaced by the correct character. Finally if the character which is incorrect should be replaced by more than one character, give the command \fBs\fR which substitutes a string of characters, ending with \s-2ESC\s0, for it. If there are a small number of characters which are wrong you can precede \fBs\fR with a count of the number of characters to be replaced. Counts are also useful with \fBx\fR to specify the number of characters to be deleted. .NH 2 More corrections: operators .PP You already know almost enough to make changes at a higher level. All you need to know now is that the .B d key acts as a delete operator. Try the command .B dw to delete a word. Try hitting \fB.\fR a few times. Notice that this repeats the effect of the \fBdw\fR. The command \fB.\fR repeats the last command which made a change. You can remember it by analogy with an ellipsis `\fB...\fR'. .PP Now try \fBdb\fR. This deletes a word backwards, namely the preceding word. Try \fBd\fR\s-2SPACE\s0. This deletes a single character, and is equivalent to the \fBx\fR command. .PP Another very useful operator is .B c or change. The command .B cw thus changes the text of a single word. You follow it by the replacement text ending with an \s-2ESC\s0. Find a word which you can change to another, and try this now. Notice that the end of the text to be changed was marked with the character `$' so that you can see this as you are typing in the new material. .sp .5 .NH 2 Operating on lines .PP It is often the case that you want to operate on lines. Find a line which you want to delete, and type \fBdd\fR, the .B d operator twice. This will delete the line. If you are on a dumb terminal, the editor may just erase the line on the screen, replacing it with a line with only an @ on it. This line does not correspond to any line in your file, but only acts as a place holder. It helps to avoid a lengthy redraw of the rest of the screen which would be necessary to close up the hole created by the deletion on a terminal without a delete line capability. .PP Try repeating the .B c operator twice; this will change a whole line, erasing its previous contents and replacing them with text you type up to an \s-2ESC\s0.\*(dg .FS \*(dg The command \fBS\fR is a convenient synonym for for \fBcc\fR, by analogy with \fBs\fR. Think of \fBS\fR as a substitute on lines, while \fBs\fR is a substitute on characters. .FE .PP You can delete or change more than one line by preceding the .B dd or .B cc with a count, i.e. \fB5dd\fR deletes 5 lines. You can also give a command like \fBdL\fR to delete all the lines up to and including the last line on the screen, or \fBd3L\fR to delete through the third from the bottom line. Try some commands like this now.* .FS * One subtle point here involves using the \fB/\fR search after a \fBd\fR. This will normally delete characters from the current position to the point of the match. If what is desired is to delete whole lines including the two points, give the pattern as \fB/pat/+0\fR, a line address. .FE Notice that the editor lets you know when you change a large number of lines so that you can see the extent of the change. The editor will also always tell you when a change you make affects text which you cannot see. .NH 2 Undoing .PP Now suppose that the last change which you made was incorrect; you could use the insert, delete and append commands to put the correct material back. However, since it is often the case that we regret a change or make a change incorrectly, the editor provides a .B u (undo) command to reverse the last change which you made. Try this a few times, and give it twice in a row to notice that an .B u also undoes a .B u. .PP The undo command lets you reverse only a single change. After you make a number of changes to a line, you may decide that you would rather have the original state of the line back. The .B U command restores the current line to the state before you started changing it. .PP You can recover text which you delete, even if undo will not bring it back; see the section on recovering lost text below. .NH 2 Summary .IP .TS lw(.50i)b a. \fR\s-2SPACE\s0\fP advance the cursor one position ^H backspace the cursor ^W erase a word during an insert \fRerase\fP your erase (usually ^H or #), erases a character during an insert \fRkill\fP your kill (usually @, ^X, or ^U), kills the insert on this line \&\fB.\fP repeats the changing command O opens and inputs new lines, above the current U undoes the changes you made to the current line a appends text after the cursor c changes the object you specify to the following text d deletes the object you specify i inserts text before the cursor o opens and inputs new lines, below the current u undoes the last change .TE .NH 1 Moving about; rearranging and duplicating text .NH 2 Low level character motions .PP Now move the cursor to a line where there is a punctuation or a bracketing character such as a parenthesis or a comma or period. Try the command \fBf\fR\fIx\fR where \fIx\fR is this character. This command finds the next \fIx\fR character to the right of the cursor in the current line. Try then hitting a \fB;\fR, which finds the next instance of the same character. By using the \fBf\fR command and then a sequence of \fB;\fR's you can often get to a particular place in a line much faster than with a sequence of word motions or \s-2SPACE\s0s. There is also a \fBF\fR command, which is like \fBf\fR, but searches backward. The \fB;\fR command repeats \fBF\fR also. .PP When you are operating on the text in a line it is often desirable to deal with the characters up to, but not including, the first instance of a character. Try \fBdf\fR\fIx\fR for some \fIx\fR now and notice that the \fIx\fR character is deleted. Undo this with \fBu\fR and then try \fBdt\fR\fIx\fR; the \fBt\fR here stands for to, i.e. delete up to the next \fIx\fR, but not the \fIx\fR. The command \fBT\fR is the reverse of \fBt\fR. .PP When working with the text of a single line, an \fB\(ua\fR moves the cursor to the first non-white position on the line, and a \fB$\fR moves it to the end of the line. Thus \fB$a\fR will append new text at the end of the current line. .PP Your file may have tab (\fB^I\fR) characters in it. These characters are represented as a number of spaces expanding to a tab stop, where tab stops are every 8 positions.* .FS * This is settable by a command of the form \fB:se ts=\fR\fIx\fR\s-2CR\s0, where \fIx\fR is 4 to set tabstops every four columns. This has effect on the screen representation within the editor. .FE When the cursor is at a tab, it sits on the last of the several spaces which represent that tab. Try moving the cursor back and forth over tabs so you understand how this works. .PP On rare occasions, your file may have nonprinting characters in it. These characters are displayed in the same way they are represented in this document, that is with a two character code, the first character of which is `^'. On the screen non-printing characters resemble a `^' character adjacent to another, but spacing or backspacing over the character will reveal that the two characters are, like the spaces representing a tab character, a single character. .PP The editor sometimes discards control characters, depending on the character and the setting of the .I beautify option, if you attempt to insert them in your file. You can get a control character in the file by beginning an insert and then typing a \fB^V\fR before the control character. The \fB^V\fR quotes the following character, causing it to be inserted directly into the file. .PP .NH 2 Higher level text objects .PP In working with a document it is often advantageous to work in terms of sentences, paragraphs, and sections. The operations \fB(\fR and \fB)\fR move to the beginning of the previous and next sentences respectively. Thus the command \fBd)\fR will delete the rest of the current sentence; likewise \fBd(\fR will delete the previous sentence if you are at the beginning of the current sentence, or the current sentence up to where you are if you are not at the beginning of the current sentence. .PP A sentence is defined to end at a `.', `!' or `?' which is followed by either the end of a line, or by two spaces. Any number of closing `)', `]', `"' and `\(aa' characters may appear after the `.', `!' or `?' before the spaces or end of line. .PP The operations \fB{\fR and \fB}\fR move over paragraphs and the operations \fB[[\fR and \fB]]\fR move over sections.\*(dg .FS \*(dg The \fB[[\fR and \fB]]\fR operations require the operation character to be doubled because they can move the cursor far from where it currently is. While it is easy to get back with the command \fB\(ga\(ga\fP, these commands would still be frustrating if they were easy to hit accidentally. .FE .PP A paragraph begins after each empty line, and also at each of a set of paragraph macros, specified by the pairs of characters in the definition of the string valued option \fIparagraphs\fR. The default setting for this option defines the paragraph macros of the \fI\-ms\fR and \fI\-mm\fR macro packages, i.e. the `.IP', `.LP', `.PP' and `.QP', `.P' and `.LI' macros.\*(dd .FS \*(dd You can easily change or extend this set of macros by assigning a different string to the \fIparagraphs\fR option in your EXINIT. See section 6.2 for details. The `.bp' directive is also considered to start a paragraph. .FE Each paragraph boundary is also a sentence boundary. The sentence and paragraph commands can be given counts to operate over groups of sentences and paragraphs. .PP Sections in the editor begin after each macro in the \fIsections\fR option, normally `.NH', `.SH', `.H' and `.HU', and each line with a formfeed \fB^L\fR in the first column. Section boundaries are always line and paragraph boundaries also. .PP Try experimenting with the sentence and paragraph commands until you are sure how they work. If you have a large document, try looking through it using the section commands. The section commands interpret a preceding count as a different window size in which to redraw the screen at the new location, and this window size is the base size for newly drawn windows until another size is specified. This is very useful if you are on a slow terminal and are looking for a particular section. You can give the first section command a small count to then see each successive section heading in a small window. .NH 2 Rearranging and duplicating text .PP The editor has a single unnamed buffer where the last deleted or changed away text is saved, and a set of named buffers \fBa\fR\-\fBz\fR which you can use to save copies of text and to move text around in your file and between files. .PP The operator .B y yanks a copy of the object which follows into the unnamed buffer. If preceded by a buffer name, \fB"\fR\fIx\fR\|\fBy\fR, where \fIx\fR here is replaced by a letter \fBa\-z\fR, it places the text in the named buffer. The text can then be put back in the file with the commands .B p and .B P; \fBp\fR puts the text after or below the cursor, while \fBP\fR puts the text before or above the cursor. .PP If the text which you yank forms a part of a line, or is an object such as a sentence which partially spans more than one line, then when you put the text back, it will be placed after the cursor (or before if you use \fBP\fR). If the yanked text forms whole lines, they will be put back as whole lines, without changing the current line. In this case, the put acts much like a \fBo\fR or \fBO\fR command. .PP Try the command \fBYP\fR. This makes a copy of the current line and leaves you on this copy, which is placed before the current line. The command \fBY\fR is a convenient abbreviation for \fByy\fR. The command \fBYp\fR will also make a copy of the current line, and place it after the current line. You can give \fBY\fR a count of lines to yank, and thus duplicate several lines; try \fB3YP\fR. .PP To move text within the buffer, you need to delete it in one place, and put it back in another. You can precede a delete operation by the name of a buffer in which the text is to be stored as in \fB"a5dd\fR deleting 5 lines into the named buffer \fIa\fR. You can then move the cursor to the eventual resting place of the these lines and do a \fB"ap\fR or \fB"aP\fR to put them back. In fact, you can switch and edit another file before you put the lines back, by giving a command of the form \fB:e \fR\fIname\fR\s-2CR\s0 where \fIname\fR is the name of the other file you want to edit. You will have to write back the contents of the current editor buffer (or discard them) if you have made changes before the editor will let you switch to the other file. An ordinary delete command saves the text in the unnamed buffer, so that an ordinary put can move it elsewhere. However, the unnamed buffer is lost when you change files, so to move text from one file to another you should use an unnamed buffer. .NH 2 Summary. .IP .TS lw(.50i)b a. \(ua first non-white on line $ end of line ) forward sentence } forward paragraph ]] forward section ( backward sentence { backward paragraph [[ backward section f\fIx\fR find \fIx\fR forward in line p put text back, after cursor or below current line y yank operator, for copies and moves t\fIx\fR up to \fIx\fR forward, for operators F\fIx\fR f backward in line P put text back, before cursor or above current line T\fIx\fR t backward in line .TE .ne 1i .NH 1 High level commands .NH 2 Writing, quitting, editing new files .PP So far we have seen how to enter .I vi and to write out our file using either \fBZZ\fR or \fB:w\fR\s-2CR\s0. The first exits from the editor, (writing if changes were made), the second writes and stays in the editor. .PP If you have changed the editor's copy of the file but do not wish to save your changes, either because you messed up the file or decided that the changes are not an improvement to the file, then you can give the command \fB:q!\fR\s-2CR\s0 to quit from the editor without writing the changes. You can also reedit the same file (starting over) by giving the command \fB:e!\fR\s-2CR\s0. These commands should be used only rarely, and with caution, as it is not possible to recover the changes you have made after you discard them in this manner. .PP You can edit a different file without leaving the editor by giving the command \fB:e\fR\ \fIname\fR\s-2CR\s0. If you have not written out your file before you try to do this, then the editor will tell you this, and delay editing the other file. You can then give the command \fB:w\fR\s-2CR\s0 to save your work and then the \fB:e\fR\ \fIname\fR\s-2CR\s0 command again, or carefully give the command \fB:e!\fR\ \fIname\fR\s-2CR\s0, which edits the other file discarding the changes you have made to the current file. To have the editor automatically save changes, include .I "set autowrite" in your EXINIT, and use \fB:n\fP instead of \fB:e\fP. .NH 2 Escaping to a shell .PP You can get to a shell to execute a single command by giving a .I vi command of the form \fB:!\fIcmd\fR\s-2CR\s0. The system will run the single command .I cmd and when the command finishes, the editor will ask you to hit a \s-2RETURN\s0 to continue. When you have finished looking at the output on the screen, you should hit \s-2RETURN\s0 and the editor will clear the screen and redraw it. You can then continue editing. You can also give another \fB:\fR command when it asks you for a \s-2RETURN\s0; in this case the screen will not be redrawn. .PP If you wish to execute more than one command in the shell, then you can give the command \fB:sh\fR\s-2CR\s0. This will give you a new shell, and when you finish with the shell, ending it by typing a \fB^D\fR, the editor will clear the screen and continue. .PP On systems which support it, \fB^Z\fP will suspend the editor and return to the (top level) shell. When the editor is resumed, the screen will be redrawn. .NH 2 Marking and returning .PP The command \fB\(ga\(ga\fR returned to the previous place after a motion of the cursor by a command such as \fB/\fR, \fB?\fR or \fBG\fR. You can also mark lines in the file with single letter tags and return to these marks later by naming the tags. Try marking the current line with the command \fBm\fR\fIx\fR, where you should pick some letter for \fIx\fR, say `a'. Then move the cursor to a different line (any way you like) and hit \fB\(gaa\fR. The cursor will return to the place which you marked. Marks last only until you edit another file. .PP When using operators such as .B d and referring to marked lines, it is often desirable to delete whole lines rather than deleting to the exact position in the line marked by \fBm\fR. In this case you can use the form \fB\(aa\fR\fIx\fR rather than \fB\(ga\fR\fIx\fR. Used without an operator, \fB\(aa\fR\fIx\fR will move to the first non-white character of the marked line; similarly \fB\(aa\(aa\fR moves to the first non-white character of the line containing the previous context mark \fB\(ga\(ga\fR. .NH 2 Adjusting the screen .PP If the screen image is messed up because of a transmission error to your terminal, or because some program other than the editor wrote output to your terminal, you can hit a \fB^L\fR, the \s-2ASCII\s0 form-feed character, to cause the screen to be refreshed. .PP On a dumb terminal, if there are @ lines in the middle of the screen as a result of line deletion, you may get rid of these lines by typing \fB^R\fR to cause the editor to retype the screen, closing up these holes. .PP Finally, if you wish to place a certain line on the screen at the top middle or bottom of the screen, you can position the cursor to that line, and then give a \fBz\fR command. You should follow the \fBz\fR command with a \s-2RETURN\s0 if you want the line to appear at the top of the window, a \fB.\fR if you want it at the center, or a \fB\-\fR if you want it at the bottom. .NH 1 Special topics .NH 2 Editing on slow terminals .PP When you are on a slow terminal, it is important to limit the amount of output which is generated to your screen so that you will not suffer long delays, waiting for the screen to be refreshed. We have already pointed out how the editor optimizes the updating of the screen during insertions on dumb terminals to limit the delays, and how the editor erases lines to @ when they are deleted on dumb terminals. .PP The use of the slow terminal insertion mode is controlled by the .I slowopen option. You can force the editor to use this mode even on faster terminals by giving the command \fB:se slow\fR\s-2CR\s0. If your system is sluggish this helps lessen the amount of output coming to your terminal. You can disable this option by \fB:se noslow\fR\s-2CR\s0. .PP The editor can simulate an intelligent terminal on a dumb one. Try giving the command \fB:se redraw\fR\s-2CR\s0. This simulation generates a great deal of output and is generally tolerable only on lightly loaded systems and fast terminals. You can disable this by giving the command \fB:se noredraw\fR\s-2CR\s0. .PP The editor also makes editing more pleasant at low speed by starting editing in a small window, and letting the window expand as you edit. This works particularly well on intelligent terminals. The editor can expand the window easily when you insert in the middle of the screen on these terminals. If possible, try the editor on an intelligent terminal to see how this works. .PP You can control the size of the window which is redrawn each time the screen is cleared by giving window sizes as argument to the commands which cause large screen motions: .DS .B ": / ? [[ ]] \(ga \(aa" .DE Thus if you are searching for a particular instance of a common string in a file you can precede the first search command by a small number, say 3, and the editor will draw three line windows around each instance of the string which it locates. .PP You can easily expand or contract the window, placing the current line as you choose, by giving a number on a \fBz\fR command, after the \fBz\fR and before the following \s-2RETURN\s0, \fB.\fR or \fB\-\fR. Thus the command \fBz5.\fR redraws the screen with the current line in the center of a five line window.\*(dg .FS \*(dg Note that the command \fB5z.\fR has an entirely different effect, placing line 5 in the center of a new window. .FE .PP If the editor is redrawing or otherwise updating large portions of the display, you can interrupt this updating by hitting a \s-2DEL\s0 or \s-2RUB\s0 as usual. If you do this you may partially confuse the editor about what is displayed on the screen. You can still edit the text on the screen if you wish; clear up the confusion by hitting a \fB^L\fR; or move or search again, ignoring the current state of the display. .PP See section 7.8 on \fIopen\fR mode for another way to use the .I vi command set on slow terminals. .NH 2 Options, set, and editor startup files .PP The editor has a set of options, some of which have been mentioned above. The most useful options are given in the following table. .PP The options are of three kinds: numeric options, string options, and toggle options. You can set numeric and string options by a statement of the form .DS \fBset\fR \fIopt\fR\fB=\fR\fIval\fR .DE and toggle options can be set or unset by statements of one of the forms .DS \fBset\fR \fIopt\fR \fBset\fR \fBno\fR\fIopt\fR .DE .KF .TS lb lb lb lb l l l a.

A list of all possible options and their values is generated by \fB:set all\fP\s-2CR\s0. Set can be abbreviated \fBse\fP. Multiple options can be placed on one line, e.g. \fB:se ai aw nu\fP\s-2CR\s0. .PP Options set by the \fBset\fP command only last while you stay in the editor. It is common to want to have certain options set whenever you use the editor. This can be accomplished by creating a list of \fIex\fP commands\*(dg .FS \*(dg All commands which start with .B : are \fIex\fP commands. .FE which are to be run every time you start up \fIex\fP, \fIedit\fP, or \fIvi\fP. A typical list includes a \fBset\fP command, and possibly a few \fBmap\fP commands. Since it is advisable to get these commands on one line, they can be separated with the | character, for example: .DS \fBset\fP ai aw terse|\fBmap\fP @ dd|\fBmap\fP # x .DE which sets the options \fIautoindent\fP, \fIautowrite\fP, \fIterse\fP, (the .B set command), makes @ delete a line, (the first .B map ), and makes # delete a character, (the second .B map ). (See section 6.9 for a description of the \fBmap\fP command) This string should be placed in the variable EXINIT in your environment. If you use the shell \fIcsh\fP, put this line in the file .I .login in your home directory: .DS setenv EXINIT \(aa\fBset\fP ai aw terse|\fBmap\fP @ dd|\fBmap\fP # x\(aa .DE If you use the standard shell \fIsh\fP, put these lines in the file .I .profile in your home directory: .DS EXINIT=\(aa\fBset\fP ai aw terse|\fBmap\fP @ dd|\fBmap\fP # x\(aa export EXINIT .DE Of course, the particulars of the line would depend on which options you wanted to set. .NH 2 Recovering lost lines .PP You might have a serious problem if you delete a number of lines and then regret that they were deleted. Despair not, the editor saves the last 9 deleted blocks of text in a set of numbered registers 1\-9. You can get the \fIn\fR'th previous deleted text back in your file by the command "\fR\fIn\fR\|\fBp\fR. The "\fR here says that a buffer name is to follow, \fIn\fR is the number of the buffer you wish to try (use the number 1 for now), and .B p is the put command, which puts text in the buffer after the cursor. If this doesn't bring back the text you wanted, hit .B u to undo this and then \fB\&.\fR (period) to repeat the put command. In general the \fB\&.\fR command will repeat the last change you made. As a special case, when the last command refers to a numbered text buffer, the \fB.\fR command increments the number of the buffer before repeating the command. Thus a sequence of the form .DS \fB"1pu.u.u.\fR .DE will, if repeated long enough, show you all the deleted text which has been saved for you. You can omit the .B u commands here to gather up all this text in the buffer, or stop after any \fB\&.\fR command to keep just the then recovered text. The command .B P can also be used rather than .B p to put the recovered text before rather than after the cursor. .NH 2 Recovering lost files .PP If the system crashes, you can recover the work you were doing to within a few changes. You will normally receive mail when you next login giving you the name of the file which has been saved for you. You should then change to the directory where you were when the system crashed and give a command of the form: .DS % \fBvi \-r\fR \fIname\fR .DE replacing \fIname\fR with the name of the file which you were editing. This will recover your work to a point near where you left off.\*(dg .FS \*(dg In rare cases, some of the lines of the file may be lost. The editor will give you the numbers of these lines and the text of the lines will be replaced by the string `LOST'. These lines will almost always be among the last few which you changed. You can either choose to discard the changes which you made (if they are easy to remake) or to replace the few lost lines by hand. .FE .PP You can get a listing of the files which are saved for you by giving the command: .DS % \fBvi \-r\fR .DE If there is more than one instance of a particular file saved, the editor gives you the newest instance each time you recover it. You can thus get an older saved copy back by first recovering the newer copies. .PP For this feature to work, .I vi must be correctly installed by a super user on your system, and the .I mail program must exist to receive mail. The invocation ``\fIvi -r\fP'' will not always list all saved files, but they can be recovered even if they are not listed. .NH 2 Continuous text input .PP When you are typing in large amounts of text it is convenient to have lines broken near the right margin automatically. You can cause this to happen by giving the command \fB:se wm=10\fR\s-2CR\s0. This causes all lines to be broken at a space at least 10 columns from the right hand edge of the screen. .PP If the editor breaks an input line and you wish to put it back together you can tell it to join the lines with \fBJ\fR. You can give \fBJ\fR a count of the number of lines to be joined as in \fB3J\fR to join 3 lines. The editor supplies white space, if appropriate, at the juncture of the joined lines, and leaves the cursor at this white space. You can kill the white space with \fBx\fR if you don't want it. .NH 2 Features for editing programs .PP The editor has a number of commands for editing programs. The thing that most distinguishes editing of programs from editing of text is the desirability of maintaining an indented structure to the body of the program. The editor has a .I autoindent facility for helping you generate correctly indented programs. .PP To enable this facility you can give the command \fB:se ai\fR\s-2CR\s0. Now try opening a new line with \fBo\fR and type some characters on the line after a few tabs. If you now start another line, notice that the editor supplies white space at the beginning of the line to line it up with the previous line. You cannot backspace over this indentation, but you can use \fB^D\fR key to backtab over the supplied indentation. .PP Each time you type \fB^D\fR you back up one position, normally to an 8 column boundary. This amount is settable; the editor has an option called .I shiftwidth which you can set to change this value. Try giving the command \fB:se sw=4\fR\s-2CR\s0 and then experimenting with autoindent again. .PP For shifting lines in the program left and right, there are operators .B < and .B >. These shift the lines you specify right or left by one .I shiftwidth. Try .B << and .B >> which shift one line left or right, and .B L shifting the rest of the display left and right. .PP If you have a complicated expression and wish to see how the parentheses match, put the cursor at a left or right parenthesis and hit \fB%\fR. This will show you the matching parenthesis. This works also for braces { and }, and brackets [ and ]. .PP If you are editing C programs, you can use the \fB[[\fR and \fB]]\fR keys to advance or retreat to a line starting with a \fB{\fR, i.e. a function declaration at a time. When \fB]]\fR is used with an operator it stops after a line which starts with \fB}\fR; this is sometimes useful with \fBy]]\fR. .NH 2 Filtering portions of the buffer .PP You can run system commands over portions of the buffer using the operator \fB!\fR. You can use this to sort lines in the buffer, or to reformat portions of the buffer with a pretty-printer. Try typing in a list of random words, one per line and ending them with a blank line. Back up to the beginning of the list, and then give the command \fB!}sort\fR\s-2CR\s0. This says to sort the next paragraph of material, and the blank line ends a paragraph. .NH 2 Commands for editing \s-2LISP\s0 .PP If you are editing a \s-2LISP\s0 program you should set the option .I lisp by doing \fB:se\ lisp\fR\s-2CR\s0. This changes the \fB(\fR and \fB)\fR commands to move backward and forward over s-expressions. The \fB{\fR and \fB}\fR commands are like \fB(\fR and \fB)\fR but don't stop at atoms. These can be used to skip to the next list, or through a comment quickly. .PP The .I autoindent option works differently for \s-2LISP\s0, supplying indent to align at the first argument to the last open list. If there is no such argument then the indent is two spaces more than the last level. .PP There is another option which is useful for typing in \s-2LISP\s0, the .I showmatch option. Try setting it with \fB:se sm\fR\s-2CR\s0 and then try typing a `(' some words and then a `)'. Notice that the cursor shows the position of the `(' which matches the `)' briefly. This happens only if the matching `(' is on the screen, and the cursor stays there for at most one second. .PP The editor also has an operator to realign existing lines as though they had been typed in with .I lisp and .I autoindent set. This is the \fB=\fR operator. Try the command \fB=%\fR at the beginning of a function. This will realign all the lines of the function declaration. .PP When you are editing \s-2LISP\s0,, the \fB[[\fR and \fR]]\fR advance and retreat to lines beginning with a \fB(\fR, and are useful for dealing with entire function definitions. .NH 2 Macros .PP .I Vi has a parameterless macro facility, which lets you set it up so that when you hit a single keystroke, the editor will act as though you had hit some longer sequence of keys. You can set this up if you find yourself typing the same sequence of commands repeatedly. .PP Briefly, there are two flavors of macros: .IP a) Ones where you put the macro body in a buffer register, say \fIx\fR. You can then type \fB@x\fR to invoke the macro. The \fB@\fR may be followed by another \fB@\fR to repeat the last macro. .IP b) You can use the .I map command from .I vi (typically in your .I EXINIT ) with a command of the form: .DS :map \fIlhs\fR \fIrhs\fR\s-2CR .DE mapping .I lhs into .I rhs. There are restrictions: .I lhs should be one keystroke (either 1 character or one function key) since it must be entered within one second (unless .I notimeout is set, in which case you can type it as slowly as you wish, and .I vi will wait for you to finish it before it echoes anything). The .I lhs can be no longer than 10 characters, the .I rhs no longer than 100. To get a space, tab or newline into .I lhs or .I rhs you should escape them with a \fB^V\fR. (It may be necessary to double the \fB^V\fR if the map command is given inside .I vi, rather than in .I ex.) Spaces and tabs inside the .I rhs need not be escaped. .PP Thus to make the \fBq\fR key write and exit the editor, you can give the command .DS :map q :wq\fB^V^V\fP\s-2CR CR\s0 .DE which means that whenever you type \fBq\fR, it will be as though you had typed the four characters \fB:wq\fR\s-2CR\s0. A \fB^V\fR's is needed because without it the \s-2CR\s0 would end the \fB:\fR command, rather than becoming part of the .I map definition. There are two .B ^V 's because from within .I vi , two .B ^V 's must be typed to get one. The first \s-2CR\s0 is part of the .I rhs , the second terminates the : command. .PP Macros can be deleted with .DS unmap lhs .DE .PP If the .I lhs of a macro is ``#0'' through ``#9'', this maps the particular function key instead of the 2 character ``#'' sequence. So that terminals without function keys can access such definitions, the form ``#x'' will mean function key .I x on all terminals (and need not be typed within one second.) The character ``#'' can be changed by using a macro in the usual way: .DS :map \fB^V^V^I\fP # .DE to use tab, for example. (This won't affect the .I map command, which still uses .B #, but just the invocation from visual mode. .PP The undo command reverses an entire macro call as a unit, if it made any changes. .PP Placing a `!' after the word .B map causes the mapping to apply to input mode, rather than command mode. Thus, to arrange for \fB^T\fP to be the same as 4 spaces in input mode, you can type: .DS :map \fB^T\fP \fB^V\fP\o'b/'\o'b/'\o'b/'\o'b/' .DE where .B \o'b/' is a blank. The \fB^V\fP is necessary to prevent the blanks from being taken as white space between the .I lhs and .I rhs . .NH Word Abbreviations .PP A feature similar to macros in input mode is word abbreviation. This allows you to type a short word and have it expanded into a longer word or words. The commands are .B :abbreviate and .B :unabbreviate (\fB:ab\fP and .B :una ) and have the same syntax as .B :map . For example: .DS :ab eecs Electrical Engineering and Computer Sciences .DE causes the word `eecs' to always be changed into the phrase `Electrical Engineering and Computer Sciences'. Word abbreviation is different from macros in that only whole words are affected. If `eecs' were typed as part of a larger word, it would be left alone. Also, the partial word is echoed as it is typed. There is no need for an abbreviation to be a single keystroke, as it should be with a macro. .NH 2 Abbreviations .PP The editor has a number of short commands which abbreviate longer commands which we have introduced here. You can find these commands easily on the quick reference card. They often save a bit of typing and you can learn them as convenient. .NH 1 Nitty-gritty details .NH 2 Line representation in the display .PP The editor folds long logical lines onto many physical lines in the display. Commands which advance lines advance logical lines and will skip over all the segments of a line in one motion. The command \fB|\fR moves the cursor to a specific column, and may be useful for getting near the middle of a long line to split it in half. Try \fB80|\fR on a line which is more than 80 columns long.\*(dg .FS \*(dg You can make long lines very easily by using \fBJ\fR to join together short lines. .FE .PP The editor only puts full lines on the display; if there is not enough room on the display to fit a logical line, the editor leaves the physical line empty, placing only an @ on the line as a place holder. When you delete lines on a dumb terminal, the editor will often just clear the lines to @ to save time (rather than rewriting the rest of the screen.) You can always maximize the information on the screen by giving the \fB^R\fR command. .PP If you wish, you can have the editor place line numbers before each line on the display. Give the command \fB:se nu\fR\s-2CR\s0 to enable this, and the command \fB:se nonu\fR\s-2CR\s0 to turn it off. You can have tabs represented as \fB^I\fR and the ends of lines indicated with `$' by giving the command \fB:se list\fR\s-2CR\s0; \fB:se nolist\fR\s-2CR\s0 turns this off. .PP Finally, lines consisting of only the character `~' are displayed when the last line in the file is in the middle of the screen. These represent physical lines which are past the logical end of file. .NH 2 Counts .PP Most .I vi commands will use a preceding count to affect their behavior in some way. The following table gives the common ways in which the counts are used: .DS .TS l lb. new window size : / ? [[ ]] \` \' scroll amount ^D ^U line/column number z G | repeat effect \fRmost of the rest\fP .TE .DE .PP The editor maintains a notion of the current default window size. On terminals which run at speeds greater than 1200 baud the editor uses the full terminal screen. On terminals which are slower than 1200 baud (most dialup lines are in this group) the editor uses 8 lines as the default window size. At 1200 baud the default is 16 lines. .PP This size is the size used when the editor clears and refills the screen after a search or other motion moves far from the edge of the current window. The commands which take a new window size as count all often cause the screen to be redrawn. If you anticipate this, but do not need as large a window as you are currently using, you may wish to change the screen size by specifying the new size before these commands. In any case, the number of lines used on the screen will expand if you move off the top with a \fB\-\fR or similar command or off the bottom with a command such as \s-2RETURN\s0 or \fB^D\fR. The window will revert to the last specified size the next time it is cleared and refilled.\*(dg .FS \*(dg But not by a \fB^L\fR which just redraws the screen as it is. .FE .PP The scroll commands \fB^D\fR and \fB^U\fR likewise remember the amount of scroll last specified, using half the basic window size initially. The simple insert commands use a count to specify a repetition of the inserted text. Thus \fB10a+\-\-\-\-\fR\s-2ESC\s0 will insert a grid-like string of text. A few commands also use a preceding count as a line or column number. .PP Except for a few commands which ignore any counts (such as \fB^R\fR), the rest of the editor commands use a count to indicate a simple repetition of their effect. Thus \fB5w\fR advances five words on the current line, while \fB5\fR\s-2RETURN\s0 advances five lines. A very useful instance of a count as a repetition is a count given to the \fB.\fR command, which repeats the last changing command. If you do \fBdw\fR and then \fB3.\fR, you will delete first one and then three words. You can then delete two more words with \fB2.\fR. .NH 2 More file manipulation commands .PP The following table lists the file manipulation commands which you can use when you are in .I vi. .KF .DS .TS lb l. :w write back changes :wq write and quit :x write (if necessary) and quit (same as ZZ). :e \fIname\fP edit file \fIname\fR :e! reedit, discarding changes :e + \fIname\fP edit, starting at end :e +\fIn\fP edit, starting at line \fIn\fP :e # edit alternate file :w \fIname\fP write file \fIname\fP :w! \fIname\fP overwrite file \fIname\fP :\fIx,y\fPw \fIname\fP write lines \fIx\fP through \fIy\fP to \fIname\fP :r \fIname\fP read file \fIname\fP into buffer :r !\fIcmd\fP read output of \fIcmd\fP into buffer :n edit next file in argument list :n! edit next file, discarding changes to current :n \fIargs\fP specify new argument list :ta \fItag\fP edit file containing tag \fItag\fP, at \fItag\fP .TE .DE .KE All of these commands are followed by a \s-2CR\s0 or \s-2ESC\s0. The most basic commands are \fB:w\fR and \fB:e\fR. A normal editing session on a single file will end with a \fBZZ\fR command. If you are editing for a long period of time you can give \fB:w\fR commands occasionally after major amounts of editing, and then finish with a \fBZZ\fR. When you edit more than one file, you can finish with one with a \fB:w\fR and start editing a new file by giving a \fB:e\fR command, or set .I autowrite and use \fB:n\fP . .PP If you make changes to the editor's copy of a file, but do not wish to write them back, then you must give an \fB!\fR after the command you would otherwise use; this forces the editor to discard any changes you have made. Use this carefully. .ne 1i .PP The \fB:e\fR command can be given a \fB+\fR argument to start at the end of the file, or a \fB+\fR\fIn\fR argument to start at line \fIn\fR\^. In actuality, \fIn\fR may be any editor command not containing a space, usefully a scan like \fB+/\fIpat\fR or \fB+?\fIpat\fR. In forming new names to the \fBe\fR command, you can use the character \fB%\fR which is replaced by the current file name, or the character \fB#\fR which is replaced by the alternate file name. The alternate file name is generally the last name you typed other than the current file. Thus if you try to do a \fB:e\fR and get a diagnostic that you haven't written the file, you can give a \fB:w\fR command and then a \fB:e #\fR command to redo the previous \fB:e\fR. .PP You can write part of the buffer to a file by finding out the lines that bound the range to be written using \fB^G\fR, and giving these numbers after the \fB:\fR and before the \fBw\fP, separated by \fB,\fR's. You can also mark these lines with \fBm\fR and then use an address of the form \fB\(aa\fR\fIx\fR\fB,\fB\(aa\fR\fIy\fR on the \fBw\fR command here. .PP You can read another file into the buffer after the current line by using the \fB:r\fR command. You can similarly read in the output from a command, just use \fB!\fR\fIcmd\fR instead of a file name. .PP If you wish to edit a set of files in succession, you can give all the names on the command line, and then edit each one in turn using the command \fB:n\fR. It is also possible to respecify the list of files to be edited by giving the \fB:n\fR command a list of file names, or a pattern to be expanded as you would have given it on the initial .I vi command. .PP If you are editing large programs, you will find the \fB:ta\fR command very useful. It utilizes a data base of function names and their locations, which can be created by programs such as .I ctags, to quickly find a function whose name you give. If the \fB:ta\fR command will require the editor to switch files, then you must \fB:w\fR or abandon any changes before switching. You can repeat the \fB:ta\fR command without any arguments to look for the same tag again. .NH 2 More about searching for strings .PP When you are searching for strings in the file with \fB/\fR and \fB?\fR, the editor normally places you at the next or previous occurrence of the string. If you are using an operator such as \fBd\fR, \fBc\fR or \fBy\fR, then you may well wish to affect lines up to the line before the line containing the pattern. You can give a search of the form \fB/\fR\fIpat\fR\fB/\-\fR\fIn\fR to refer to the \fIn\fR'th line before the next line containing \fIpat\fR, or you can use \fB+\fR instead of \fB\-\fR to refer to the lines after the one containing \fIpat\fR. If you don't give a line offset, then the editor will affect characters up to the match place, rather than whole lines; thus use ``+0'' to affect to the line which matches. .PP You can have the editor ignore the case of words in the searches it does by giving the command \fB:se ic\fR\s-2CR\s0. The command \fB:se noic\fR\s-2CR\s0 turns this off. .ne 1i .PP Strings given to searches may actually be regular expressions. If you do not want or need this facility, you should .DS set nomagic .DE in your EXINIT. In this case, only the characters \fB\(ua\fR and \fB$\fR are special in patterns. The character \fB\e\fR is also then special (as it is most everywhere in the system), and may be used to get at the an extended pattern matching facility. It is also necessary to use a \e before a \fB/\fR in a forward scan or a \fB?\fR in a backward scan, in any case. The following table gives the extended forms when \fBmagic\fR is set. .DS .TS lb l. \(ua at beginning of pattern, matches beginning of line $ at end of pattern, matches end of line \fB\&.\fR matches any character \e< matches the beginning of a word \e> matches the end of a word [\fIstr\fP] matches any single character in \fIstr\fP [\(ua\fIstr\fP] matches any single character not in \fIstr\fP [\fIx\fP\-\fIy\fP] matches any character between \fIx\fP and \fIy\fP * matches any number of the preceding pattern .TE .DE If you use \fBnomagic\fR mode, then the \fB. [\fR and \fB*\fR primitives are given with a preceding \e. .NH 2 More about input mode .PP There are a number of characters which you can use to make corrections during input mode. These are summarized in the following table. .sp .5 .DS .TS lb l. ^H deletes the last input character ^W deletes the last input word, defined as by \fBb\fR erase your erase character, same as \fB^H\fP kill your kill character, deletes the input on this line \e escapes a following \fB^H\fP and your erase and kill \s-2ESC\s0 ends an insertion \s-2DEL\s0 interrupts an insertion, terminating it abnormally \s-2CR\s0 starts a new line ^D backtabs over \fIautoindent\fP 0^D kills all the \fIautoindent\fP \(ua^D same as \fB0^D\fP, but restores indent next line ^V quotes the next non-printing character into the file .TE .DE .sp .5 .PP The most usual way of making corrections to input is by typing \fB^H\fR to correct a single character, or by typing one or more \fB^W\fR's to back over incorrect words. If you use \fB#\fR as your erase character in the normal system, it will work like \fB^H\fR. .PP Your system kill character, normally \fB@\fR, \fB^X\fP or \fB^U\fR, will erase all the input you have given on the current line. In general, you can neither erase input back around a line boundary nor can you erase characters which you did not insert with this insertion command. To make corrections on the previous line after a new line has been started you can hit \s-2ESC\s0 to end the insertion, move over and make the correction, and then return to where you were to continue. The command \fBA\fR which appends at the end of the current line is often useful for continuing. .PP If you wish to type in your erase or kill character (say # or @) then you must precede it with a \fB\e\fR, just as you would do at the normal system command level. A more general way of typing non-printing characters into the file is to precede them with a \fB^V\fR. The \fB^V\fR echoes as a \fB\(ua\fR character on which the cursor rests. This indicates that the editor expects you to type a control character. In fact you may type any character and it will be inserted into the file at that point.* .FS * This is not quite true. The implementation of the editor does not allow the \s-2NULL\s0 (\fB^@\fR) character to appear in files. Also the \s-2LF\s0 (linefeed or \fB^J\fR) character is used by the editor to separate lines in the file, so it cannot appear in the middle of a line. You can insert any other character, however, if you wait for the editor to echo the \fB\(ua\fR before you type the character. In fact, the editor will treat a following letter as a request for the corresponding control character. This is the only way to type \fB^S\fR or \fB^Q\fP, since the system normally uses them to suspend and resume output and never gives them to the editor to process. .FE .PP If you are using \fIautoindent\fR you can backtab over the indent which it supplies by typing a \fB^D\fR. This backs up to a \fIshiftwidth\fR boundary. This only works immediately after the supplied \fIautoindent\fR. .PP When you are using \fIautoindent\fR you may wish to place a label at the left margin of a line. The way to do this easily is to type \fB\(ua\fR and then \fB^D\fR. The editor will move the cursor to the left margin for one line, and restore the previous indent on the next. You can also type a \fB0\fR followed immediately by a \fB^D\fR if you wish to kill all the indent and not have it come back on the next line. .NH 2 Upper case only terminals .PP If your terminal has only upper case, you can still use .I vi by using the normal system convention for typing on such a terminal. Characters which you normally type are converted to lower case, and you can type upper case letters by preceding them with a \e. The characters { ~ } | \(ga are not available on such terminals, but you can escape them as \e( \e\(ua \e) \e! \e\(aa. These characters are represented on the display in the same way they are typed.\*(dd .FS \*(dd The \e character you give will not echo until you type another key. .FE .NH 2 Vi and ex .PP .I Vi is actually one mode of editing within the editor .I ex. When you are running .I vi you can escape to the line oriented editor of .I ex by giving the command \fBQ\fR. All of the .B : commands which were introduced above are available in .I ex. Likewise, most .I ex commands can be invoked from .I vi using :. Just give them without the \fB:\fR and follow them with a \s-2CR\s0. .PP In rare instances, an internal error may occur in .I vi. In this case you will get a diagnostic and be left in the command mode of .I ex. You can then save your work and quit if you wish by giving a command \fBx\fR after the \fB:\fR which \fIex\fR prompts you with, or you can reenter \fIvi\fR by giving .I ex a .I vi command. .PP There are a number of things which you can do more easily in .I ex than in .I vi. Systematic changes in line oriented material are particularly easy. You can read the advanced editing documents for the editor .I ed to find out a lot more about this style of editing. Experienced users often mix their use of .I ex command mode and .I vi command mode to speed the work they are doing. .NH 2 Open mode: vi on hardcopy terminals and ``glass tty's'' \(dd .PP If you are on a hardcopy terminal or a terminal which does not have a cursor which can move off the bottom line, you can still use the command set of .I vi, but in a different mode. When you give a .I vi command, the editor will tell you that it is using .I open mode. This name comes from the .I open command in .I ex, which is used to get into the same mode. .PP The only difference between .I visual mode and .I open mode is the way in which the text is displayed. .PP In .I open mode the editor uses a single line window into the file, and moving backward and forward in the file causes new lines to be displayed, always below the current line. Two commands of .I vi work differently in .I open: .B z and \fB^R\fR. The .B z command does not take parameters, but rather draws a window of context around the current line and then returns you to the current line. .PP If you are on a hardcopy terminal, the .B ^R command will retype the current line. On such terminals, the editor normally uses two lines to represent the current line. The first line is a copy of the line as you started to edit it, and you work on the line below this line. When you delete characters, the editor types a number of \e's to show you the characters which are deleted. The editor also reprints the current line soon after such changes so that you can see what the line looks like again. .PP It is sometimes useful to use this mode on very slow terminals which can support .I vi in the full screen mode. You can do this by entering .I ex and using an .I open command. .LP .SH Acknowledgements .PP Bruce Englar encouraged the early development of this display editor. Peter Kessler helped bring sanity to version 2's command layout. Bill Joy wrote versions 1 and 2.0 through 2.7, and created the framework that users see in the present editor. Mark Horton added macros and other features and made the editor work on a large number of terminals and Unix systems. nvi-1.81.6/docs/vitut/vi.summary0100644000076400001440000002344310720065506015620 0ustar skimousers.\" Copyright (c) 1980, 1993 .\" The Regents of the University of California.

Introduction

Text editing using a terminal connected to a computer allows you to create, modify, and print text easily. A text editor is a program that assists you as you create and modify text. The text editor you will learn here is named edit. Creating text using edit is as easy as typing it on an electric typewriter. Modifying text involves telling the text editor what you want to add, change, or delete. You can review your text by typing a command to print the file contents as they are currently. Another program (which we do not discuss in this document), a text formatter, rearranges your text for you into ``finished form.''

These lessons assume no prior familiarity with computers or with text editing. They consist of a series of text editing sessions which lead you through the fundamental steps of creating and revising text. After scanning each lesson and before beginning the next, you should try the examples at a terminal to get a feeling for the actual process of text editing. If you set aside some time for experimentation, you will soon become familiar with using the computer to write and modify text. In addition to the actual use of the text editor, other features of UNIX will be very important to your work. You can begin to learn about these other features by reading one of the other tutorials that provide a general introduction to the system. You will be ready to proceed with this lesson as soon as you are familiar with (1) your terminal and its special keys, (2) how to login, (3) and the ways of correcting typing errors. Let's first define some terms:

program A set of instructions, given to the computer, describing the sequence of steps the computer performs in order to accomplish a specific task. The task must be specific, such as balancing your checkbook or editing your text. A general task, such as working for world peace, is something we can all do, but not something we can currently write programs to do.
UNIX UNIX is a special type of program, called an operating system, that supervises the machinery and all other programs comprising the total computer system.
edit edit is the name of the UNIX text editor you will be learning to use, and is a program that aids you in writing or revising text. Edit was designed for beginning users, and is a simplified version of an editor named ex.
file Each UNIX account is allotted space for the permanent storage of information, such as programs, data or text. A file is a logical unit of data, for example, an essay, a program, or a chapter from a book, which is stored on a computer system. Once you create a file, it is kept until you instruct the system to remove it. You may create a file during one UNIX session, end the session, and return to use it at a later time. Files contain anything you choose to write and store in them. The sizes of files vary to suit your needs; one file might hold only a single number, yet another might contain a very long document or program. The only way to save information from one session to the next is to store it in a file, which you will learn in Session 1.
filename Filenames are used to distinguish one file from another, serving the same purpose as the labels of manila folders in a file cabinet. In order to write or access information in a file, you use the name of that file in a UNIX command, and the system will automatically locate the file.
disk Files are stored on an input/output device called a disk, which looks something like a stack of phonograph records. Each surface is coated with a material similar to that on magnetic recording tape, and information is recorded on it.
buffer A temporary work space, made available to the user for the duration of a session of text editing and used for creating and modifying the text file. We can think of the buffer as a blackboard that is erased after each class, where each session with the editor is a class.

Session 1

Making contact with UNIX

To use the editor you must first make contact with the computer by logging in to UNIX . We'll quickly review the standard UNIX login procedure for the two ways you can make contact: on a terminal that is directly linked to the computer, or over a telephone line where the computer answers your call.

Directly-linked terminals

Turn on your terminal and press the RETURN key. You are now ready to login.

Dial-up terminals

If your terminal connects with the computer over a telephone line, turn on the terminal, dial the system access number, and, when you hear a high-pitched tone, place the telephone handset in the acoustic coupler, if you are using one. You are now ready to login.

Logging in

The message inviting you to login is:

          login:

Type your login name, which identifies you to UNIX , on the same line as the login message, and press RETURN . If the terminal you are using has both upper and lower case, be sure you enter your login name in lower case; otherwise UNIX assumes your terminal has only upper case and will not recognize lower case letters you may type. UNIX types ``login:'' and you reply with your login name, for example ``susan'':

          login: susan (and press the RETURN key)

(In the examples, input you would type appears in bold face to distinguish it from the responses from UNIX .)

UNIX will next respond with a request for a password as an additional precaution to prevent unauthorized people from using your account. The password will not appear when you type it, to prevent others from seeing it. The message is:

          Password:    (type your password and press RETURN)

If any of the information you gave during the login sequence was mistyped or incorrect, UNIX will respond with

          Login incorrect.

          login:

in which case you should start the login process anew. Assuming that you have successfully logged in, UNIX will print the message of the day and eventually will present you with a % at the beginning of a fresh line. The % is the UNIX prompt symbol which tells you that UNIX is ready to accept a command.

Asking for e ed di it t

You are ready to tell UNIX that you want to work with edit, the text editor. Now is a convenient time to choose a name for the file of text you are about to create. To begin your editing session, type edit followed by a space and then the filename you have selected; for example, ``text''. After that, press the RETURN key and wait for edit's response:

          % edit text    (followed by a RETURN)
          "text" No such file or directory
          :

If you typed the command correctly, you will now be in communication with edit. Edit has set aside a buffer for use as a temporary working space during your current editing session. Since ``text'' is a new file we are about to create the editor was unable to find that file, which it confirms by saying:

          "text" No such file or directory

On the next line appears edit's prompt ``:'', announcing that you are in command mode and edit expects a command from you. You may now begin to create the new file.

The ``Command not found'' message

If you misspelled edit by typing, say, ``editor'', this might appear:

          % editor
          editor: Command not found
          %

Your mistake in calling edit ``editor'' was treated by UNIX as a request for a program named ``editor''. Since there is no program named ``editor'', UNIX reported that the program was ``not found''. A new % indicates that UNIX is ready for another command, and you may then enter the correct command.

A summary

Your exchange with UNIX as you logged in and made contact with edit should look something like this:

          login: susan
          Password:
          ... A Message of General Interest ...
          % edit text
          "text" No such file or directory
          :

Entering text

You may now begin entering text into the buffer. This is done by appending (or adding) text to whatever is currently in the buffer. Since there is nothing in the buffer at the moment, you are appending text to nothing; in effect, since you are adding text to nothing you are creating text. Most edit commands have two equivalent forms: a word that suggests what the command does, and a shorter abbreviation of that word. Many beginners find the full command names easier to remember at first, but once you are familiar with editing you may prefer to type the shorter abbreviations. The command to input text is ``append''. (It may be abbreviated ``a''.) Type append and press the RETURN key.

          % edit text
          :append

Messages from e ed di it t

If you make a mistake in entering a command and type something that edit does not recognize, edit will respond with a message intended to help you diagnose your error. For example, if you misspell the command to input text by typing, perhaps, ``add'' instead of ``append'' or ``a'', you will receive this message:

          :add
          add: Not an editor command
          :

When you receive a diagnostic message, check what you typed in order to determine what part of your command confused edit. The message above means that edit was unable to recognize your mistyped command and, therefore, did not execute it. Instead, a new ``:'' appeared to let you know that edit is again ready to execute a command.

Text input mode

By giving the command ``append'' (or using the abbreviation ``a''), you entered text input mode, also known as append mode. When you enter text input mode, edit stops sending you a prompt. You will not receive any prompts or error messages while in text input mode. You can enter pretty much anything you want on the lines. The lines are transmitted one by one to the buffer and held there during the editing session. You may append as much text as you want, and when you wish to stop entering text lines you should type a period as the only character on the line and press the RETURN key. When you type the period and press RETURN , you signal that you want to stop appending text, and edit responds by allowing you to exit text input mode and reenter command mode. Edit will again prompt you for a command by printing ``:''.

Leaving append mode does not destroy the text in the buffer. You have to leave append mode to do any of the other kinds of editing, such as changing, adding, or printing text. If you type a period as the first character and type any other character on the same line, edit will believe you want to remain in append mode and will not let you out. As this can be very frustrating, be sure to type only the period and the RETURN key.

This is a good place to learn an important lesson about computers and text: a blank space is a character as far as a computer is concerned. If you so much as type a period followed by a blank (that is, type a period and then the space bar on the keyboard), you will remain in append mode with the last line of text being:


          .

Let's say that you enter the lines (try to type exactly what you see, including ``thiss''):

          This is some sample text.
          And thiss is some more text.
          Text editing is strange, but nice.
          .

The last line is the period followed by a RETURN that gets you out of append mode.

Making corrections

If you have read a general introduction to UNIX , you will recall that it is possible to erase individual letters that you have typed. This is done by typing the designated erase character as many times as there are characters you want to erase.

The usual erase character varies from place to place and user to user. Often it is the backspace (control-H), so you can correct typing errors in the line you are typing by holding down the CTRL key and typing the ``H'' key. (Sometimes it is the DEL key.) If you type the erase character you will notice that the terminal backspaces in the line you are on. You can backspace over your error, and then type what you want to be the rest of the line.

If you make a bad start in a line and would like to begin again, you can either backspace to the beginning of the line or you can use the at-sign ``@'' to erase everything on the line:

          Text edtiing is strange, but@
          Text editing is strange, but nice.

When you type the at-sign (@), you erase the entire line typed so far and are given a fresh line to type on. You may immediately begin to retype the line. This, unfortunately, does not work after you type the line and press RETURN . To make corrections in lines that have been completed, it is necessary to use the editing commands covered in the next sessions.

Writing text to disk

You are now ready to edit the text. One common operation is to write the text to disk as a file for safekeeping after the session is over. This is the only way to save information from one session to the next, since the editor's buffer is temporary and will last only until the end of the editing session. Learning how to write a file to disk is second in importance only to entering the text. To write the contents of the buffer to a disk file, use the command ``write'' (or its abbreviation ``w''):

          :write

Edit will copy the contents of the buffer to a disk file. If the file does not yet exist, a new file will be created automatically and the presence of a ``[New file]'' will be noted. The newly-created file will be given the name specified when you entered the editor, in this case ``text''. To confirm that the disk file has been successfully written, edit will repeat the filename and give the number of lines and the total number of characters in the file. The buffer remains unchanged by the ``write'' command. All of the lines that were written to disk will still be in the buffer, should you want to modify or add to them.

Edit must have a name for the file to be written. If you forgot to indicate the name of the file when you began to edit, edit will print in response to your write command:

          No current filename

If this happens, you can specify the filename in a new write command:

          :write text

After the ``write'' (or ``w''), type a space and then the name of the file.

Signing off

We have done enough for this first lesson on using the UNIX text editor, and are ready to quit the session with edit. To do this we type ``quit'' (or ``q'') and press RETURN :

          :write
          "text" [New file]  3 lines, 90 characters
          :quit
          %

The % is from UNIX to tell you that your session with edit is over and you may command UNIX further. Since we want to end the entire session at the terminal, we also need to exit from UNIX . In response to the UNIX prompt of ``%'' type the command

          %logout

This will end your session with UNIX , and will ready the terminal for the next user. It is always important to type logout at the end of a session to make absolutely sure no one could accidentally stumble into your abandoned session and thus gain access to your files, tempting even the most honest of souls.

This is the end of the first session on UNIX text editing.

Edit: A Tutorial USD:11-5

Session 2

Login with UNIX as in the first session:

          login: susan  (carriage return)
          Password:       (give password and carriage return)

          ... A Message of General Interest ...
          %

When you indicate you want to edit, you can specify the name of the file you worked on last time. This will start edit working, and it will fetch the contents of the file into the buffer, so that you can resume editing the same file. When edit has copied the file into the buffer, it will repeat its name and tell you the number of lines and characters it contains. Thus,

          % edit text
          "text" 3 lines, 90 characters
          :

means you asked edit to fetch the file named ``text'' for editing, causing it to copy the 90 characters of text into the buffer. Edit awaits your further instructions, and indicates this by its prompt character, the colon (:). In this session, we will append more text to our file, print the contents of the buffer, and learn to change the text of a line.

Adding more text to the file

If you want to add more to the end of your text you may do so by using the append command to enter text input mode. When ``append'' is the first command of your editing session, the lines you enter are placed at the end of the buffer. Here we'll use the abbreviation for the append command, ``a'':

          :a
          This is text added in Session 2.
          It doesn't mean much here, but
          it does illustrate the editor.
          .

You may recall that once you enter append mode using the ``a'' (or ``append'') command, you need to type a line containing only a period (.) to exit append mode.

Interrupt

Should you press the RUB key (sometimes labelled DELETE ) while working with edit, it will send this message to you:

          Interrupt
          :

Any command that edit might be executing is terminated by rub or delete, causing edit to prompt you for a new command. If you are appending text at the time, you will exit from append mode and be expected to give another command. The line of text you were typing when the append command was interrupted will not be entered into the buffer.

Making corrections

If while typing the line you hit an incorrect key, recall that you may delete the incorrect character or cancel the entire line of input by erasing in the usual way. Refer either to the last few pages of Session 1 if you need to review the procedures for making a correction. The most important idea to remember is that erasing a character or cancelling a line must be done before you press the RETURN key.

Listing what's in the buffer (p)

Having appended text to what you wrote in Session 1, you might want to see all the lines in the buffer. To print the contents of the buffer, type the command:

          :1,$p

The ``1''

stands for line 1 of the buffer, the ``$'' is a special symbol designating the last line of the buffer, and ``p'' (or print) is the command to print from line 1 to the end of the buffer. The command ``1,$p'' gives you:

          This is some sample text.
          And thiss is some more text.
          Text editing is strange, but nice.
          This is text added in Session 2.
          It doesn't mean much here, but
          it does illustrate the editor.

Occasionally, you may accidentally type a character that can't be printed, which can be done by striking a key while the CTRL key is pressed. In printing lines, edit uses a special notation to show the existence of non-printing characters. Suppose you had introduced the non-printing character ``control-A'' into the word ``illustrate'' by accidently pressing the CTRL key while typing ``a''. This can happen on many terminals because the CTRL key and the ``A'' key are beside each other. If your finger presses between the two keys, control-A results. When asked to print the contents of the buffer, edit would display

          it does illustr^Ate the editor.

To represent the control-A, edit shows ``^A''. The sequence ``^'' followed by a capital letter stands for the one character entered by holding down the CTRL key and typing the letter which appears after the ``^''. We'll soon discuss the commands that can be used to correct this typing error.

In looking over the text we see that ``this'' is typed as ``thiss'' in the second line, a deliberate error so we can learn to make corrections. Let's correct the spelling.

Finding things in the buffer

In order to change something in the buffer we first need to find it. We can find ``thiss'' in the text we have entered by looking at a listing of the lines. Physically speaking, we search the lines of text looking for ``thiss'' and stop searching when we have found it. The way to tell edit to search for something is to type it inside slash marks:

          :/thiss/

By typing /thiss/ and pressing RETURN , you instruct edit to search for ``thiss''. If you ask edit to look for a pattern of characters which it cannot find in the buffer, it will respond ``Pattern not found''. When edit finds the characters ``thiss'', it will print the line of text for your inspection:

          And thiss is some more text.

Edit is now positioned in the buffer at the line it just printed, ready to make a change in the line.

USD:11-6 Edit: A Tutorial

The current line

Edit keeps track of the line in the buffer where it is located at all times during an editing session. In general, the line that has been most recently printed, entered, or changed is the current location in the buffer. The editor is prepared to make changes at the current location in the buffer, unless you direct it to another location.

In particular, when you bring a file into the buffer, you will be located at the last line in the file, where the editor left off copying the lines from the file to the buffer. If your first editing command is ``append'', the lines you enter are added to the end of the file, after the current line -- the last line in the file.

You can refer to your current location in the buffer by the symbol period (.) usually known by the name ``dot''. If you type ``.'' and carriage return you will be instructing edit to print the current line:

          :.
          And thiss is some more text.

If you want to know the number of the current line, you can type .= and press RETURN , and edit will respond with the line number:

          :.=
          2

If you type the number of any line and press RETURN , edit will position you at that line and print its contents:

          :2
          And thiss is some more text.

You should experiment with these commands to gain experience in using them to make changes.

Numbering lines (nu)

The number (nu) command is similar to print, giving both the number and the text of each printed line. To see the number and the text of the current line type

          :nu
               2  And thiss is some more text.

Note that the shortest abbreviation for the number command is ``nu'' (and not ``n'', which is used for a different command). You may specify a range of lines to be listed by the number command in the same way that lines are specified for print. For example, 1,$nu lists all lines in the buffer with their corresponding line numbers.

Substitute command (s)

Now that you have found the misspelled word, you can change it from ``thiss'' to ``this''. As far as edit is concerned, changing things is a matter of substituting one thing for another. As a stood for append, so s stands for substitute. We will use the abbreviation ``s'' to reduce the chance of mistyping the substitute command. This command will instruct edit to make the change:

          2s/thiss/this/

We first indicate the line to be changed, line 2, and then type an ``s'' to indicate we want edit to make a substitution. Inside the first set of slashes are the characters that we want to change, followed by the characters to replace them, and then a closing slash mark. To summarize:

          2s/ what is to be changed / what to change it to /

If edit finds an exact match of the characters to be changed it will make the change only in the first occurrence of the characters. If it does not find the characters to be changed, it will respond:

          Substitute pattern match failed

indicating that your instructions could not be carried out. When edit does find the characters that you want to change, it will make the substitution and automatically print the changed line, so that you can check that the correct substitution was made. In the example,

          :2s/thiss/this/
          And this is some more text.

line 2 (and line 2 only) will be searched for the characters ``thiss'', and when the first exact match is found, ``thiss'' will be changed to ``this''. Strictly speaking, it was not necessary above to specify the number of the line to be changed. In

          :s/thiss/this/

edit will assume that we mean to change the line where we are currently located (``.''). In this case, the command without a line number would have produced the same result because we were already located at the line we wished to change.

For another illustration of the substitute command, let us choose the line:

          Text editing is strange, but nice.

You can make this line a bit more positive by taking out the characters ``strange, but '' so the line reads:

          Text editing is nice.

A command that will first position edit at the desired line and then make the substitution is:

          :/strange/s/strange, but //

What we have done here is combine our search with our substitution. Such combinations are perfectly legal, and speed up editing quite a bit once you get used to them. That is, you do not necessarily have to use line numbers to identify a line to edit. Instead, you may identify the line you want to change by asking edit to search for a specified pattern of letters that occurs in that line. The parts of the above command are:

You should note the space after ``but'' in ``/strange, but /''. If you do not indicate that the space is to be taken out, your line will read:

          Text editing is   nice.

which looks a little funny because of the extra space between ``is'' and ``nice''. Again, we realize from this that a blank space is a real character to a computer, and in editing text we need to be aware of spaces within a line just as we would be aware of an ``a'' or a ``4''.

Another way to list what's in the buffer (z)

Although the print command is useful for looking at specific lines in the buffer, other commands may be more convenient for viewing large sections of text. You can ask to see a screen full of text at a time by using the command z. If you type

          :1z

edit will start with line 1 and continue printing lines, stopping either when the screen of your terminal is full or when the last line in the buffer has been printed. If you want to read the next segment of text, type the command

          :z

If no starting line number is given for the z command, printing will start at the ``current'' line, in this case the last line printed. Viewing lines in the buffer one screen full at a time is known as paging. Paging can also be used to print a section of text on a hard-copy terminal.

Saving the modified text

This seems to be a good place to pause in our work, and so we should end the second session. If you (in haste) type ``q'' to quit the session your dialogue with edit will be:

          :q
          No write since last change (:quit! overrides)
          :

This is edit's warning that you have not written the modified contents of the buffer to disk. You run the risk of losing the work you did during the editing session since you typed the latest write command. Because in this lesson we have not written to disk at all, everything we have done would have been lost if edit had obeyed the q command. If you did not want to save the work done during this editing session, you would have to type ``q!'' or (``quit!'') to confirm that you indeed wanted to end the session immediately, leaving the file as it was after the most recent ``write'' command. However, since you want to save what you have edited, you need to type:

          :w
          "text" 6 lines, 171 characters

and then follow with the commands to quit and logout:

          :q
          % logout

and hang up the phone or turn off the terminal when UNIX asks for a name. Terminals connected to the port selector will stop after the logout command, and pressing keys on the keyboard will do nothing.

This is the end of the second session on UNIX text editing.

Edit: A Tutorial USD:11-7

Session 3

Bringing text into the buffer (e)

Login to UNIX and make contact with edit. You should try to login without looking at the notes, but if you must then by all means do.

Did you remember to give the name of the file you wanted to edit? That is, did you type

          % edit text

or simply

          % edit

Both ways get you in contact with edit, but the first way will bring a copy of the file named ``text'' into the buffer. If you did forget to tell edit the name of your file, you can get it into the buffer by typing:

          :e text
          "text" 6 lines, 171 characters

The command edit, which may be abbreviated e, tells edit that you want to erase anything that might already be in the buffer and bring a copy of the file ``text'' into the buffer for editing. You may also use the edit (e) command to change files in the middle of an editing session, or to give edit the name of a new file that you want to create. Because the edit command clears the buffer, you will receive a warning if you try to edit a new file without having saved a copy of the old file. This gives you a chance to write the contents of the buffer to disk before editing the next file.

Moving text in the buffer (m)

Edit allows you to move lines of text from one location in the buffer to another by means of the move (m) command. The first two examples are for illustration only, though after you have read this Session you are welcome to return to them for practice. The command

          :2,4m$

directs edit to move lines 2, 3, and 4 to the end of the buffer ($). The format for the move command is that you specify the first line to be moved, the last line to be moved, the move command ``m'', and the line after which the moved text is to be placed. So,

          :1,3m6

would instruct edit to move lines 1 through 3 (inclusive) to a location after line 6 in the buffer. To move only one line, say, line 4, to a location in the buffer after line 5, the command would be ``4m5''.

Let's move some text using the command:

          :5,$m1
          2 lines moved
          it does illustrate the editor.

After executing a command that moves more than one line of the buffer, edit tells how many lines were affected by the move and prints the last moved line for your inspection. If you want to see more than just the last line, you can then use the print (p), z, or number (nu) command to view more text. The buffer should now contain:

          This is some sample text.
          It doesn't mean much here, but
          it does illustrate the editor.
          And this is some more text.
          Text editing is nice.
          This is text added in Session 2.

You can restore the original order by typing:

          :4,$m1

or, combining context searching and the move command:

          :/And this is some/,/This is text/m/This is some sample/

(Do not type both examples here!) The problem with combining context searching with the move command is that your chance of making a typing error in such a long command is greater than if you type line numbers.

Copying lines (copy)

The copy command is used to make a second copy of specified lines, leaving the original lines where they were. Copy has the same format as the move command, for example:

          :2,5copy $

makes a copy of lines 2 through 5, placing the added lines after the buffer's end ($). Experiment with the copy command so that you can become familiar with how it works. Note that the shortest abbreviation for copy is co (and not the letter ``c'', which has another meaning).

Deleting lines (d)

Suppose you want to delete the line

          This is text added in Session 2.

from the buffer. If you know the number of the line to be deleted, you can type that number followed by delete or d. This example deletes line 4, which is ``This is text added in Session 2.'' if you typed the commands suggested so far.

          :4d
          It doesn't mean much here, but

Here ``4'' is the number of the line to be deleted, and ``delete'' or ``d'' is the command to delete the line. After executing the delete command, edit prints the line that has become the current line (``.'').

If you do not happen to know the line number you can search for the line and then delete it using this sequence of commands:

          :/added in Session 2./
          This is text added in Session 2.
          :d
          It doesn't mean much here, but

The ``/added in Session 2./'' asks edit to locate and print the line containing the indicated text, starting its search at the current line and moving line by line until it finds the text. Once you are sure that you have correctly specified the line you want to delete, you can enter the delete (d) command. In this case it is not necessary to specify a line number before the ``d''. If no line number is given, edit deletes the current line (``.''), that is, the line found by our search. After the deletion, your buffer should contain:

          This is some sample text.
          And this is some more text.
          Text editing is nice.
          It doesn't mean much here, but
          it does illustrate the editor.
          And this is some more text.
          Text editing is nice.
          This is text added in Session 2.
          It doesn't mean much here, but

To delete both lines 2 and 3:

          And this is some more text.
          Text editing is nice.

you type

          :2,3d
          2 lines deleted

which specifies the range of lines from 2 to 3, and the operation on those lines -- ``d'' for delete. If you delete more than one line you will receive a message telling you the number of lines deleted, as indicated in the example above.

The previous example assumes that you know the line numbers for the lines to be deleted. If you do not you might combine the search command with the delete command:

          :/And this is some/,/Text editing is nice./d

A word or two of caution

In using the search function to locate lines to be deleted you should be absolutely sure the characters you give as the basis for the search will take edit to the line you want deleted. Edit will search for the first occurrence of the characters starting from where you last edited - that is, from the line you see printed if you type dot (.).

A search based on too few characters may result in the wrong lines being deleted, which edit will do as easily as if you had meant it. For this reason, it is usually safer to specify the search and then delete in two separate steps, at least until you become familiar enough with using the editor that you understand how best to specify searches. For a beginner it is not a bad idea to double-check each command before pressing RETURN to send the command on its way.

Undo (u) to the rescue

The undo (u) command has the ability to reverse the effects of the last command that changed the buffer. To undo the previous command, type ``u'' or ``undo''. Undo can rescue the contents of the buffer from many an unfortunate mistake. However, its powers are not unlimited, so it is still wise to be reasonably careful about the commands you give.

It is possible to undo only commands which have the power to change the buffer -- for example, delete, append, move, copy, substitute, and even undo itself. The commands write (w) and edit (e), which interact with disk files, cannot be undone, nor can commands that do not change the buffer, such as print. Most importantly, the only command that can be reversed by undo is the last ``undo-able'' command you typed. You can use control-H and @ to change commands while you are typing them, and undo to reverse the effect of the commands after you have typed them and pressed RETURN .

To illustrate, let's issue an undo command. Recall that the last buffer-changing command we gave deleted the lines formerly numbered 2 and 3. Typing undo at this moment will reverse the effects of the deletion, causing those two lines to be replaced in the buffer.

          :u
          2 more lines in file after undo
          And this is some more text.

Here again, edit informs you if the command affects more than one line, and prints the text of the line which is now ``dot'' (the current line).

More about the dot (.) and buffer end ($)

The function assumed by the symbol dot depends on its context. It can be used:

1. to exit from append mode; we type dot (and only a dot) on a line and press RETURN ;
2. to refer to the line we are at in the buffer.

Dot can also be combined with the equal sign to get the number of the line currently being edited:

          :.=

If we type ``.='' we are asking for the number of the line, and if we type ``.'' we are asking for the text of the line.

In this editing session and the last, we used the dollar sign to indicate the end of the buffer in commands such as print, copy, and move. The dollar sign as a command asks edit to print the last line in the buffer. If the dollar sign is combined with the equal sign ($=) edit will print the line number corresponding to the last line in the buffer.

``.'' and ``$'', then, represent line numbers. Whenever appropriate, these symbols can be used in place of line numbers in commands. For example

          :.,$d

instructs edit to delete all lines from the current line (.) to the end of the buffer.

Moving around in the buffer (+ and -)

When you are editing you often want to go back and re-read a previous line. You could specify a context search for a line you want to read if you remember some of its text, but if you simply want to see what was written a few, say 3, lines ago, you can type

          -3p

This tells edit to move back to a position 3 lines before the current line (.) and print that line. You can move forward in the buffer similarly:

          +2p

instructs edit to print the line that is 2 ahead of your current position.

You may use ``+'' and ``-'' in any command where edit accepts line numbers. Line numbers specified with ``+'' or ``-'' can be combined to print a range of lines. The command

          :-1,+2copy$

makes a copy of 4 lines: the current line, the line before it, and the two after it. The copied lines will be placed after the last line in the buffer ($), and the original lines referred to by ``-1'' and ``+2'' remain where they are.

Try typing only ``-''; you will move back one line just as if you had typed ``-1p''. Typing the command ``+'' works similarly. You might also try typing a few plus or minus signs in a row (such as ``+++'') to see edit's response. Typing RETURN alone on a line is the equivalent of typing ``+1p''; it will move you one line ahead in the buffer and print that line.

If you are at the last line of the buffer and try to move further ahead, perhaps by typing a ``+'' or a carriage return alone on the line, edit will remind you that you are at the end of the buffer:

          At end-of-file

or

          Not that many lines in buffer

Similarly, if you try to move to a position before the first line, edit will print one of these messages:

          Nonzero address required on this command

or

          Negative address - first buffer line is 1

The number associated with a buffer line is the line's ``address'', in that it can be used to locate the line.

Changing lines (c)

You can also delete certain lines and insert new text in their place. This can be accomplished easily with the change (c) command. The change command instructs edit to delete specified lines and then switch to text input mode to accept the text that will replace them. Let's say you want to change the first two lines in the buffer:

          This is some sample text.
          And this is some more text.

to read

          This text was created with the UNIX text editor.

To do so, you type:

          :1,2c
          2 lines changed
          This text was created with the UNIX text editor.
          .
          :

In the command 1,2c we specify that we want to change the range of lines beginning with 1 and ending with 2 by giving line numbers as with the print command. These lines will be deleted. After you type RETURN to end the change command, edit notifies you if more than one line will be changed and places you in text input mode. Any text typed on the following lines will be inserted into the position where lines were deleted by the change command. You will remain in text input mode until you exit in the usual way, by typing a period alone on a line. Note that the number of lines added to the buffer need not be the same as the number of lines deleted.

This is the end of the third session on text editing with UNIX .

USD:11-8 Edit: A Tutorial

Session 4

This lesson covers several topics, starting with commands that apply throughout the buffer, characters with special meanings, and how to issue UNIX commands while in the editor. The next topics deal with files: more on reading and writing, and methods of recovering files lost in a crash. The final section suggests sources of further information.

Making commands global (g)

One disadvantage to the commands we have used for searching or substituting is that if you have a number of instances of a word to change it appears that you have to type the command repeatedly, once for each time the change needs to be made. Edit, however, provides a way to make commands apply to the entire contents of the buffer - the global (g) command.

To print all lines containing a certain sequence of characters (say, ``text'') the command is:

          :g/text/p

The ``g'' instructs edit to make a global search for all lines in the buffer containing the characters ``text''. The ``p'' prints the lines found.

To issue a global command, start by typing a ``g'' and then a search pattern identifying the lines to be affected. Then, on the same line, type the command to be executed for the identified lines. Global substitutions are frequently useful. For example, to change all instances of the word ``text'' to the word ``material'' the command would be a combination of the global search and the substitute command:

          :g/text/s/text/material/g

Note the ``g'' at the end of the global command, which instructs edit to change each and every instance of ``text'' to ``material''. If you do not type the ``g'' at the end of the command only the first instance of ``text'' in each line will be changed (the normal result of the substitute command). The ``g'' at the end of the command is independent of the ``g'' at the beginning. You may give a command such as:

          :5s/text/material/g

to change every instance of ``text'' in line 5 alone. Further, neither command will change ``text'' to ``material'' if ``Text'' begins with a capital rather than a lower-case t.

Edit does not automatically print the lines modified by a global command. If you want the lines to be printed, type a ``p'' at the end of the global command:

          :g/text/s/text/material/gp

You should be careful about using the global command in combination with any other - in essence, be sure of what you are telling edit to do to the entire buffer. For example,

          :g/ /d
          72 less lines in file after global

will delete every line containing a blank anywhere in it. This could adversely affect your document, since most lines have spaces between words and thus would be deleted. After executing the global command, edit will print a warning if the command added or deleted more than one line. Fortunately, the undo command can reverse the effects of a global command. You should experiment with the global command on a small file of text to see what it can do for you.

More about searching and substituting

In using slashes to identify a character string that we want to search for or change, we have always specified the exact characters. There is a less tedious way to repeat the same string of characters. To change ``text'' to ``texts'' we may type either

          :/text/s/text/texts/

as we have done in the past, or a somewhat abbreviated command:

          :/text/s//texts/

In this example, the characters to be changed are not specified - there are no characters, not even a space, between the two slash marks that indicate what is to be changed. This lack of characters between the slashes is taken by the editor to mean ``use the characters we last searched for as the characters to be changed.''

Similarly, the last context search may be repeated by typing a pair of slashes with nothing between them:

          :/does/
          It doesn't mean much here, but
          ://
          it does illustrate the editor.

(You should note that the search command found the characters ``does'' in the word ``doesn't'' in the first search request.) Because no characters are specified for the second search, the editor scans the buffer for the next occurrence of the characters ``does''.

Edit normally searches forward through the buffer, wrapping around from the end of the buffer to the beginning, until the specified character string is found. If you want to search in the reverse direction, use question marks (?) instead of slashes to surround the characters you are searching for.

It is also possible to repeat the last substitution without having to retype the entire command. An ampersand (&) used as a command repeats the most recent substitute command, using the same search and replacement patterns. After altering the current line by typing

          :s/text/texts/

you type

          :/text/&

or simply

          ://&

to make the same change on the next line in the buffer containing the characters ``text''.

Special characters

Two characters have special meanings when used in specifying searches: ``$'' and ``^''. ``$'' is taken by the editor to mean ``end of the line'' and is used to identify strings that occur at the end of a line.

          :g/text.$/s//material./p

tells the editor to search for all lines ending in ``text.'' (and nothing else, not even a blank space), to change each final ``text.'' to ``material.'', and print the changed lines.

The symbol ``^'' indicates the beginning of a line. Thus,

          :s/^/1. /

instructs the editor to insert ``1.'' and a space at the beginning of the current line.

The characters ``$'' and ``^'' have special meanings only in the context of searching. At other times, they are ordinary characters. If you ever need to search for a character that has a special meaning, you must indicate that the character is to lose temporarily its special significance by typing another special character, the backslash (), before it.

          :s/\$/dollar/

looks for the character ``$'' in the current line and replaces it by the word ``dollar''. Were it not for the backslash, the ``$'' would have represented ``the end of the line'' in your search rather than the character ``$''. The backslash retains its special significance unless it is preceded by another backslash.

Issuing UNIX commands from the editor

After creating several files with the editor, you may want to delete files no longer useful to you or ask for a list of your files. Removing and listing files are not functions of the editor, and so they require the use of UNIX system commands (also referred to as ``shell'' commands, as ``shell'' is the name of the program that processes UNIX commands). You do not need to quit the editor to execute a UNIX command as long as you indicate that it is to be sent to the shell for execution. To use the UNIX command rm to remove the file named ``junk'' type:

          :!rm junk
          !
          :

The exclamation mark (!) indicates that the rest of the line is to be processed as a shell command. If the buffer contents have not been written since the last change, a warning will be printed before the command is executed:

          [No write since last change]

The editor prints a ``!'' when the command is completed. Other tutorials describe useful features of the system, of which an editor is only one part.

Filenames and file manipulation

Throughout each editing session, edit keeps track of the name of the file being edited as the current filename. Edit remembers as the current filename the name given when you entered the editor. The current filename changes whenever the edit (e) command is used to specify a new file. Once edit has recorded a current filename, it inserts that name into any command where a filename has been omitted. If a write command does not specify a file, edit, as we have seen, supplies the current filename. If you are editing a file named ``draft3'' having 283 lines in it, you can have the editor write onto a different file by including its name in the write command:

          :w chapter3
          "chapter3" [new file] 283 lines, 8698 characters

The current filename remembered by the editor will not be changed as a result of the write command. Thus, if the next write command does not specify a name, edit will write onto the current file (``draft3'') and not onto the file ``chapter3''.

The file (f) command

To ask for the current filename, type file (or f). In response, the editor provides current information about the buffer, including the filename, your current position, the number of lines in the buffer, and the percent of the distance through the file your current location is.

          :f
          "text" [Modified] line 3 of 4 --75%--

If the contents of the buffer have changed since the last time the file was written, the editor will tell you that the file has been ``[Modified]''. After you save the changes by writing onto a disk file, the buffer will no longer be considered modified:

          :w
          "text" 4 lines, 88 characters
          :f
          "text" line 3 of 4 --75%--

Reading additional files (r)

The read (r) command allows you to add the contents of a file to the buffer at a specified location, essentially copying new lines between two existing lines. To use it, specify the line after which the new text will be placed, the read (r) command, and then the name of the file. If you have a file named ``example'', the command

          :$r example
          "example" 18 lines, 473 characters

reads the file ``example'' and adds it to the buffer after the last line. The current filename is not changed by the read command.

Writing parts of the buffer

The write (w) command can write all or part of the buffer to a file you specify. We are already familiar with writing the entire contents of the buffer to a disk file. To write only part of the buffer onto a file, indicate the beginning and ending lines before the write command, for example

          :45,$w ending

Here all lines from 45 through the end of the buffer are written onto the file named ending. The lines remain in the buffer as part of the document you are editing, and you may continue to edit the entire buffer. Your original file is unaffected by your command to write part of the buffer to another file. Edit still remembers whether you have saved changes to the buffer in your original file or not.

Recovering files

Although it does not happen very often, there are times UNIX stops working because of some malfunction. This situation is known as a crash. Under most circumstances, edit's crash recovery feature is able to save work to within a few lines of changes before a crash (or an accidental phone hang up). If you lose the contents of an editing buffer in a system crash, you will normally receive mail when you login that gives the name of the recovered file. To recover the file, enter the editor and type the command recover (rec), followed by the name of the lost file. For example, to recover the buffer for an edit session involving the file ``chap6'', the command is:

          :recover chap6

Recover is sometimes unable to save the entire buffer successfully, so always check the contents of the saved buffer carefully before writing it back onto the original file. For best results, write the buffer to a new file temporarily so you can examine it without risk to the original file. Unfortunately, you cannot use the recover command to retrieve a file you removed using the shell command rm.

Other recovery techniques

If something goes wrong when you are using the editor, it may be possible to save your work by using the command preserve (pre), which saves the buffer as if the system had crashed. If you are writing a file and you get the message ``Quota exceeded'', you have tried to use more disk storage than is allotted to your account. Proceed with caution because it is likely that only a part of the editor's buffer is now present in the file you tried to write. In this case you should use the shell escape from the editor (!) to remove some files you don't need and try to write the file again. If this is not possible and you cannot find someone to help you, enter the command

          :preserve

and wait for the reply,

          File preserved.

If you do not receive this reply, seek help immediately. Do not simply leave the editor. If you do, the buffer will be lost, and you may not be able to save your file. If the reply is ``File preserved.'' you can leave the editor (or logout) to remedy the situation. After a preserve, you can use the recover command once the problem has been corrected, or the -r option of the edit command if you leave the editor and want to return.

If you make an undesirable change to the buffer and type a write command before discovering your mistake, the modified version will replace any previous version of the file. Should you ever lose a good version of a document in this way, do not panic and leave the editor. As long as you stay in the editor, the contents of the buffer remain accessible. Depending on the nature of the problem, it may be possible to restore the buffer to a more complete state with the undo command. After fixing the damaged buffer, you can again write the file to disk.

Further reading and other information

Edit is an editor designed for beginning and casual users. It is actually a version of a more powerful editor called ex. These lessons are intended to introduce you to the editor and its more commonly-used commands. We have not covered all of the editor's commands, but a selection of commands that should be sufficient to accomplish most of your editing tasks. You can find out more about the editor in the Ex Reference Manual, which is applicable to both ex and edit. One way to become familiar with the manual is to begin by reading the description of commands that you already know.

Using e ex x

As you become more experienced with using the editor, you may still find that edit continues to meet your needs. However, should you become interested in using ex, it is easy to switch. To begin an editing session with ex, use the name ex in your command instead of edit.

Edit commands also work in ex, but the editing environment is somewhat different. You should be aware of a few differences between ex and edit. In edit, only the characters ``^'', ``$'', and ``'' have special meanings in searching the buffer or indicating characters to be changed by a substitute command. Several additional characters have special meanings in ex, as described in the Ex Reference Manual. Another feature of the edit environment prevents users from accidently entering two alternative modes of editing, open and visual, in which the editor behaves quite differently from normal command mode. If you are using ex and you encounter strange behavior, you may have accidently entered open mode by typing ``o''. Type the ESC key and then a ``Q'' to get out of open or visual mode and back into the regular editor command mode. The document An Introduction to Display Editing with Vi provide full details of visual mode.

Ex a line oriented text editor, which supports both command and display oriented editing. This reference manual describes the command oriented part of ex; the display editing features of ex are described in An Introduction to Display Editing with Vi. Other documents about the editor include the introduction Edit: A tutorial, the Ex/edit Command Summary, and a Vi Quick Reference card.

1. Starting ex

Each instance of the editor has a set of options, which can be set to tailor it to your liking. The command edit invokes a version of ex designed for more casual or beginning users by changing the default settings of some of these options. To simplify the description which follows we assume the default settings of the options.

When invoked, ex determines the terminal type from the TERM variable in the environment. It there is a TERMCAP variable in the environment, and the type of the terminal described there matches the TERM variable, then that description is used. Also if the TERMCAP variable contains a pathname (beginning with a /) then the editor will seek the description of the terminal in that file (rather than the default /etc/termcap). If there is a variable EXINIT in the environment, then the editor will execute the commands in that variable, otherwise if there is a file .exrc in your HOME directory ex reads commands from that file, simulating a source command. Option setting commands placed in EXINIT or .exrc will be executed before each editor session.

A command to enter ex has the following prototype:

     ex [ - ] [ -v ] [ -t tag ] [ -r ] [ -l ] [ -wn ] [ -x ] [ -R ] [ +command ] name ...

The most common case edits a single file with no options, i.e.:

     ex name

The - command line option option suppresses all interactive-user feedback and is useful in processing editor scripts in command files. The -v option is equivalent to using vi rather than ex. The -t option is equivalent to an initial tag command, editing the file containing the tag and positioning the editor at its definition. The -r option is used in recovering after an editor or system crash, retrieving the last saved version of the named file or, if no file is specified, typing a list of saved files. The -l option sets up for editing LISP , setting the showmatch and lisp options. The -w option sets the default window size to n, and is useful on dialups to start in small windows. The -x option causes ex to prompt for a key, which is used to encrypt and decrypt the contents of the file, which should already be encrypted using the same key, see crypt(1). The -R option sets the readonly option at the start. Name arguments indicate files to be edited. An argument of the form +command indicates that the editor should begin by executing the specified command. If command is omitted, then it defaults to ``$'', positioning the editor at the last line of the first file initially. Other useful commands here are scanning patterns of the form ``/pat'' or line numbers, e.g. ``+100'' starting at line 100.

2. File manipulation

2.1. Current file

Ex is normally editing the contents of a single file, whose name is recorded in the current file name. Ex performs all editing actions in a buffer (actually a temporary file) into which the text of the file is initially read. Changes made to the buffer have no effect on the file being edited unless and until the buffer contents are written out to the file with a write command. After the buffer contents are written, the previous contents of the written file are no longer accessible. When a file is edited, its name becomes the current file name, and its contents are read into the buffer.

The current file is almost always considered to be edited. This means that the contents of the buffer are logically connected with the current file name, so that writing the current buffer contents onto that file, even if it exists, is a reasonable action. If the current file is not edited then ex will not normally write on it if it already exists.*

2.2. Alternate file

Each time a new value is given to the current file name, the previous current file name is saved as the alternate file name. Similarly if a file is mentioned but does not become the current file, it is saved as the alternate file name.

2.3. Filename expansion

Filenames within the editor may be specified using the normal shell expansion conventions. In addition, the character `%' in filenames is replaced by the current file name and the character `#' by the alternate file name.

2.4. Multiple files and named buffers

If more than one file is given on the command line, then the first file is edited as described above. The remaining arguments are placed with the first file in the argument list. The current argument list may be displayed with the args command. The next file in the argument list may be edited with the next command. The argument list may also be respecified by specifying a list of names to the next command. These names are expanded, the resulting list of names becomes the new argument list, and ex edits the first file on the list.

For saving blocks of text while editing, and especially when editing more than one file, ex has a group of named buffers. These are similar to the normal buffer, except that only a limited number of operations are available on them. The buffers have names a through z.

2.5. Read only

It is possible to use ex in read only mode to look at files that you have no intention of modifying. This mode protects you from accidently overwriting the file. Read only mode is on when the readonly option is set. It can be turned on with the -R command line option, by the view command line invocation, or by setting the readonly option. It can be cleared by setting noreadonly. It is possible to write, even while in read only mode, by indicating that you really know what you are doing. You can write to a different file, or can use the ! form of write, even while in read only mode.

3. Exceptional Conditions

3.1. Errors and interrupts

When errors occur ex (optionally) rings the terminal bell and, in any case, prints an error diagnostic. If the primary input is from a file, editor processing will terminate. If an interrupt signal is received, ex prints ``Interrupt'' and returns to its command level. If the primary input is a file, then ex will exit when this occurs.

3.2. Recovering from hangups and crashes

If a hangup signal is received and the buffer has been modified since it was last written out, or if the system crashes, either the editor (in the first case) or the system (after it reboots in the second) will attempt to preserve the buffer. The next time you log in you should be able to recover the work you were doing, losing at most a few lines of changes from the last point before the hangup or editor crash. To recover a file you can use the -r option. If you were editing the file resume, then you should change to the directory where you were when the crash occurred, giving the command

     ex -r resume

After checking that the retrieved file is indeed ok, you can write it over the previous contents of that file.

You will normally get mail from the system telling you when a file has been saved after a crash. The command

     ex -r

will print a list of the files which have been saved for you. (In the case of a hangup, the file will not appear in the list, although it can be recovered.)

4. Editing modes

Ex has five distinct modes. The primary mode is command mode. Commands are entered in command mode when a `:' prompt is present, and are executed each time a complete line is sent. In text input mode ex gathers input lines and places them in the file. The append, insert, and change commands use text input mode. No prompt is printed when you are in text input mode. This mode is left by typing a `.' alone at the beginning of a line, and command mode resumes.

The last three modes are open and visual modes, entered by the commands of the same name, and, within open and visual modes text insertion mode. Open and visual modes allow local editing operations to be performed on the text in the file. The open command displays one line at a time on any terminal while visual works on CRT terminals with random positioning cursors, using the screen as a (single) window for file editing changes. These modes are described (only) in An Introduction to Display Editing with Vi.

5. Command structure

Most command names are English words, and initial prefixes of the words are acceptable abbreviations. The ambiguity of abbreviations is resolved in favor of the more commonly used commands.*

5.1. Command parameters

Most commands accept prefix addresses specifying the lines in the file upon which they are to have effect. The forms of these addresses will be discussed below. A number of commands also may take a trailing count specifying the number of lines to be involved in the command.

Thus the command ``10p'' will print the tenth line in the buffer while ``delete 5'' will delete five lines from the buffer, starting with the current line.

Some commands take other information or parameters, this information always being given after the command name.

5.2. Command variants

A number of commands have two distinct variants. The variant form of the command is invoked by placing an `!' immediately after the command name. Some of the default variants may be controlled by options; in this case, the `!' serves to toggle the default.

5.3. Flags after commands

The characters `#', `p' and `l' may be placed after many commands.**

In this case, the command abbreviated by these characters is executed after the command completes. Since ex normally prints the new current line after each change, `p' is rarely necessary. Any number of `+' or `-' characters may also be given with these flags. If they appear, the specified offset is applied to the current line value before the printing command is executed.

5.4. Comments

It is possible to give editor commands which are ignored. This is useful when making complex editor scripts for which comments are desired. The comment character is the double quote: ". Any command line beginning with " is ignored. Comments beginning with " may also be placed at the ends of commands, except in cases where they could be confused as part of text (shell escapes and the substitute and map commands).

5.5. Multiple commands per line

More than one command may be placed on a line by separating each pair of commands by a `|' character. However the global commands, comments, and the shell escape `!' must be the last command on a line, as they are not terminated by a `|'.

5.6. Reporting large changes

Most commands which change the contents of the editor buffer give feedback if the scope of the change exceeds a threshold given by the report option. This feedback helps to detect undesirably large changes so that they may be quickly and easily reversed with an undo. After commands with more global effect such as global or visual, you will be informed if the net change in the number of lines in the buffer during this command exceeds this threshold.

6. Command addressing

6.1. Addressing primitives

. The current line. Most commands leave the current line as the last line which they affect. The default address for most commands is the current line, thus `.' is rarely used alone as an address.
n The nth line in the editor's buffer, lines being numbered sequentially from 1.
$ The last line in the buffer.
% An abbreviation for ``1,$'', the entire buffer.
+n -n An offset relative to the current buffer line.

/ pat / ? pat ? Scan forward and backward respectively for a line containing pat, a regular expression (as defined below). The scans normally wrap around the end of the buffer. If all that is desired is to print the next line containing pat, then the trailing / or ? may be omitted. If pat is omitted or explicitly empty, then the last regular expression specified is located.

x Before each non-relative motion of the current line `.', the previous current line is marked with a tag, subsequently referred to as `'. This makes it easy to refer or return to this previous context. Marks may also be established by the mark command, using single lower case letters x and the marked lines referred to as `x'.

6.2. Combining addressing primitives

Addresses to commands consist of a series of addressing primitives, separated by `,' or `;'. Such address lists are evaluated left-to-right. When addresses are separated by `;' the current line `.' is set to the value of the previous addressing expression before the next address is interpreted. If more addresses are given than the command requires, then all but the last one or two are ignored. If the command takes two addresses, the first addressed line must precede the second in the buffer.

7. Command descriptions

The following form is a prototype for all ex commands:

     address command ! parameters count flags

All parts are optional; the degenerate case is the empty command which prints the next line in the file. For sanity with use from within visual mode, ex ignores a ``:'' preceding any command.

In the following command descriptions, the default addresses are shown in parentheses, which are not, however, part of the command.

abbreviate word rhs abbr: ab

Add the named abbreviation to the current list. When in input mode in visual, if word is typed as a complete word, it will be changed to rhs.

( . ) append abbr: a
text
.

Reads the input text and places it after the specified line. After the command, `.' addresses the last line input or the specified line if no lines were input. If address `0' is given, text is placed at the beginning of the buffer.

a!
text
.

The variant flag to append toggles the setting for the autoindent option during the input of text.

args

The members of the argument list are printed, with the current argument delimited by `[' and `]'.

( . , . ) change count abbr: c
text
.

Replaces the specified lines with the input text. The current line becomes the last line input; if no lines were input it is left as for a delete.

c!
text
.

The variant toggles autoindent during the change.

( . , . )copy addr flags abbr: co

A copy of the specified lines is placed after addr, which may be `0'. The current line `.' addresses the last line of the copy. The command t is a synonym for copy.

( . , . )delete buffer count flags abbr: d

Removes the specified lines from the buffer. The line after the last line deleted becomes the current line; if the lines deleted were originally at the end, the new last line becomes the current line. If a named buffer is specified by giving a letter, then the specified lines are saved in that buffer, or appended to it if an upper case letter is used.

edit file abbr: e
ex file

Used to begin an editing session on a new file. The editor first checks to see if the buffer has been modified since the last write command was issued. If it has been, a warning is issued and the command is aborted. The command otherwise deletes the entire contents of the editor buffer, makes the named file the current file and prints the new filename. After insuring that this file is sensible

the editor reads the file into its buffer.
If the read of the file completes without error, the number of lines and characters read is typed. If there were any non- ASCII characters in the file they are stripped of their non- ASCII high bits, and any null characters in the file are discarded. If none of these errors occurred, the file is considered edited. If the last line of the input file is missing the trailing newline character, it will be supplied and a complaint will be issued. This command leaves the current line `.' at the last line read.

e! file

The variant form suppresses the complaint about modifications having been made and not written from the editor buffer, thus discarding all changes which have been made before editing the new file.

e +n file

Causes the editor to begin at line n rather than at the last line; n may also be an editor command containing no spaces, e.g.: ``+/pat''.

file abbr: f

Prints the current file name, whether it has been `[Modified]' since the last write command, whether it is read only, the current line, the number of lines in the buffer, and the percentage of the way through the buffer of the current line.*

file file

The current file name is changed to file which is considered `[Not edited]'.

( 1 , $ ) global /pat/ cmds abbr: g

First marks each line among those specified which matches the given regular expression. Then the given command list is executed with `.' initially set to each marked line.
The command list consists of the remaining commands on the current input line and may continue to multiple lines by ending all but the last such line with a `'. If cmds (and possibly the trailing / delimiter) is omitted, each line matching pat is printed. Append, insert, and change commands and associated input are permitted; the `.' terminating input may be omitted if it would be on the last line of the command list. Open and visual commands are permitted in the command list and take input from the terminal.
The global command itself may not appear in cmds. The undo command is also not permitted there, as undo instead can be used to reverse the entire global command. The options autoprint and autoindent are inhibited during a global, (and possibly the trailing / delimiter) and the value of the report option is temporarily infinite, in deference to a report for the entire global. Finally, the context mark `' is set to the value of `.' before the global command begins and is not changed during a global command, except perhaps by an open or visual within the global.

g! /pat/ cmds abbr: v

The variant form of global runs cmds at each line not matching pat.

( . )insert abbr: i
text
.

Places the given text before the specified line. The current line is left at the last line input; if there were none input it is left at the line before the addressed line. This command differs from append only in the placement of text.

i!
text
.

The variant toggles autoindent during the insert.

( . , .+1 ) join count flags abbr: j

Places the text from a specified range of lines together on one line. White space is adjusted at each junction to provide at least one blank character, two if there was a `.' at the end of the line, or none if the first following character is a `)'. If there is already white space at the end of the line, then the white space at the start of the next line will be discarded.

j!

The variant causes a simpler join with no white space processing; the characters in the lines are simply concatenated.

( . ) k x

The k command is a synonym for mark. It does not require a blank or tab before the following letter.

( . , . ) list count flags

Prints the specified lines in a more unambiguous way: tabs are printed as `^I' and the end of each line is marked with a trailing `$'. The current line is left at the last line printed.

map lhs rhs

The map command is used to define macros for use in visual mode. Lhs should be a single character, or the sequence ``#n'', for n a digit, referring to function key n. When this character or function key is typed in visual mode, it will be as though the corresponding rhs had been typed. On terminals without function keys, you can type ``#n''. See section 6.9 of the ``Introduction to Display Editing with Vi'' for more details.

( . ) mark x

Gives the specified line mark x, a single lower case letter. The x must be preceded by a blank or a tab. The addressing form `x' then addresses this line. The current line is not affected by this command.

( . , . ) move addr abbr: m

The move command repositions the specified lines to be after addr. The first of the moved lines becomes the current line.

next abbr: n

The next file from the command line argument list is edited.

n!

The variant suppresses warnings about the modifications to the buffer not having been written out, discarding (irretrievably) any changes which may have been made.

n filelist
n +command filelist

The specified filelist is expanded and the resulting list replaces the current argument list; the first file in the new list is then edited. If command is given (it must contain no spaces), then it is executed after editing the first such file.

( . , . ) number count flags abbr: # or nu

Prints each specified line preceded by its buffer line number. The current line is left at the last line printed.

( . ) open flags abbr: o
( . ) open /pat/ flags

Enters intraline editing open mode at each addressed line. If pat is given, then the cursor will be placed initially at the beginning of the string matched by the pattern. To exit this mode use Q. See An Introduction to Display Editing with Vi for more details.

preserve

The current editor buffer is saved as though the system had just crashed. This command is for use only in emergencies when a write command has resulted in an error and you don't know how to save your work. After a preserve you should seek help.

( . , . )print count abbr: p or P

Prints the specified lines with non-printing characters printed as control characters `^x'; delete (octal 177) is represented as `^?'. The current line is left at the last line printed.

( . )put buffer abbr: pu

Puts back previously deleted or yanked lines. Normally used with delete to effect movement of lines, or with yank to effect duplication of lines. If no buffer is specified, then the last deleted or yanked text is restored.*

By using a named buffer, text may be restored that was saved there at any previous time.

quit abbr: q

Causes ex to terminate. No automatic write of the editor buffer to a file is performed. However, ex issues a warning message if the file has changed since the last write command was issued, and does not quit.

Normally, you will wish to save your changes, and you should give a write command; if you wish to discard them, use the q! command variant.

q!

Quits from the editor, discarding changes to the buffer without complaint.

( . ) read file abbr: r

Places a copy of the text of the given file in the editing buffer after the specified line. If no file is given the current file name is used. The current file name is not changed unless there is none in which case file becomes the current name. The sensibility restrictions for the edit command apply here also. If the file buffer is empty and there is no current name then ex treats this as an edit command.
Address `0' is legal for this command and causes the file to be read at the beginning of the buffer. Statistics are given as for the edit command when the read successfully terminates. After a read the current line is the last line read.

( . ) read !command

Reads the output of the command command into the buffer after the specified line. This is not a variant form of the command, rather a read specifying a command rather than a filename; a blank or tab before the ! is mandatory.

recover file

Recovers file from the system save area. Used after a accidental hangup of the phone**

or a system crash** or preserve command. Except when you use preserve you will be notified by mail when a file is saved.

rewind abbr: rew

The argument list is rewound, and the first file in the list is edited.

rew!

Rewinds the argument list discarding any changes made to the current buffer.

set parameter

With no arguments, prints those options whose values have been changed from their defaults; with parameter all it prints all of the option values.
Giving an option name followed by a `?' causes the current value of that option to be printed. The `?' is unnecessary unless the option is Boolean valued. Boolean options are given values either by the form `set option' to turn them on or `set nooption' to turn them off; string and numeric options are assigned via the form `set option=value'.
More than one parameter may be given to set; they are interpreted left-to-right.

shell abbr: sh

A new shell is created. When it terminates, editing resumes.

source file abbr: so

Reads and executes commands from the specified file. Source commands may be nested.

( . , . ) substitute /pat/repl/ options count flagsabbr: s

On each specified line, the first instance of pattern pat is replaced by replacement pattern repl. If the global indicator option character `g' appears, then all instances are substituted; if the confirm indication character `c' appears, then before each substitution the line to be substituted is typed with the string to be substituted marked with `' characters. By typing an `y' one can cause the substitution to be performed, any other input causes no change to take place. After a substitute the current line is the last line substituted.
Lines may be split by substituting new-line characters into them. The newline in repl must be escaped by preceding it with a `'. Other metacharacters available in pat and repl are described below.

stop

Suspends the editor, returning control to the top level shell. If autowrite is set and there are unsaved changes, a write is done first unless the form stop! is used. This commands is only available where supported by the teletype driver and operating system.

( . , . ) substitute options count flagsabbr: s

If pat and repl are omitted, then the last substitution is repeated. This is a synonym for the & command.

( . , . ) t addr flags

The t command is a synonym for copy.

ta tag

The focus of editing switches to the location of tag, switching to a different line in the current file where it is defined, or if necessary to another file.

The tags file is normally created by a program such as ctags, and consists of a number of lines with three fields separated by blanks or tabs. The first field gives the name of the tag, the second the name of the file where the tag resides, and the third gives an addressing form which can be used by the editor to find the tag; this field is usually a contextual scan using `/pat/' to be immune to minor changes in the file. Such scans are always performed as if nomagic was set.

The tag names in the tags file must be sorted alphabetically.

unabbreviate word abbr: una

Delete word from the list of abbreviations.

undo abbr: u

Reverses the changes made in the buffer by the last buffer editing command. Note that global commands are considered a single command for the purpose of undo (as are open and visual.) Also, the commands write and edit which interact with the file system cannot be undone. Undo is its own inverse.
Undo always marks the previous value of the current line `.' as `'. After an undo the current line is the first line restored or the line before the first line deleted if no lines were restored. For commands with more global effect such as global and visual the current line regains it's pre-command value after an undo.

unmap lhs

The macro expansion associated by map for lhs is removed.

( 1 , $ ) v /pat/ cmds

A synonym for the global command variant g!, running the specified cmds on each line which does not match pat.

version abbr: ve

Prints the current version number of the editor as well as the date the editor was last changed.

( . ) visual type count flags abbr: vi

Enters visual mode at the specified line. Type is optional and may be `-' , `' or `.' as in the z command to specify the placement of the specified line on the screen. By default, if type is omitted, the specified line is placed as the first on the screen. A count specifies an initial window size; the default is the value of the option window. See the document An Introduction to Display Editing with Vi for more details. To exit this mode, type Q.

visual file
visual +n file

From visual mode, this command is the same as edit.

( 1 , $ ) write file abbr: w

Writes changes made back to file, printing the number of lines and characters written. Normally file is omitted and the text goes back where it came from. If a file is specified, then text will be written to that file.*

If the file does not exist it is created. The current file name is changed only if there is no current file name; the current line is never changed.
If an error occurs while writing the current and edited file, the editor considers that there has been ``No write since last change'' even if the buffer had not previously been modified.

( 1 , $ ) write>> file abbr: w>>

Writes the buffer contents at the end of an existing file.

w! name

Overrides the checking of the normal write command, and will write to any file which the system permits.

( 1 , $ ) w !command

Writes the specified lines into command. Note the difference between w! which overrides checks and w ! which writes to a command.

wq name

Like a write and then a quit command.

wq! name

The variant overrides checking on the sensibility of the write command, as w! does.

xit name

If any changes have been made and not written, writes the buffer out. Then, in any case, quits.

( . , . )yank buffer count abbr: ya

Places the specified lines in the named buffer, for later retrieval via put. If no buffer name is specified, the lines go to a more volatile place; see the put command description.

( .+1 ) z count

Print the next count lines, default window.

( . ) z type count

Prints a window of text with the specified line at the top. If type is `-' the line is placed at the bottom; a `.' causes the line to be placed in the center.* A count gives the number of lines to be displayed rather than double the number specified by the scroll option. On a CRT the screen is cleared before display begins unless a count which is less than the screen size is given. The current line is left at the last line printed.

! command

The remainder of the line after the `!' character is sent to a shell to be executed. Within the text of command the characters `%' and `#' are expanded as in filenames and the character `!' is replaced with the text of the previous command. Thus, in particular, `!!' repeats the last such shell escape. If any such expansion is performed, the expanded line will be echoed. The current line is unchanged by this command.
If there has been ``[No write]'' of the buffer contents since the last change to the editing buffer, then a diagnostic will be printed before the command is executed as a warning. A single `!' is printed when the command completes.

( addr , addr ) ! command

Takes the specified address range and supplies it as standard input to command; the resulting output then replaces the input lines.

( $ ) =

Prints the line number of the addressed line. The current line is unchanged.

( . , . ) > count flags
( . , . ) < count flags

Perform intelligent shifting on the specified lines; < shifts left and > shift right. The quantity of shift is determined by the shiftwidth option and the repetition of the specification character. Only white space (blanks and tabs) is shifted; no non-white characters are discarded in a left-shift. The current line becomes the last line which changed due to the shifting.

^D

An end-of-file from a terminal input scrolls through the file. The scroll option specifies the size of the scroll, normally a half screen of text.

( .+1 , .+1 )
( .+1 , .+1 ) |

An address alone causes the addressed lines to be printed. A blank line prints the next line in the file.

( . , . ) & options count flags

Repeats the previous substitute command.

( . , . ) ~ options count flags

Replaces the previous regular expression with the previous replacement pattern from a substitution.

8. Regular expressions and substitute replacement patterns

8.1. Regular expressions

A regular expression specifies a set of strings of characters. A member of this set of strings is said to be matched by the regular expression. Ex remembers two previous regular expressions: the previous regular expression used in a substitute command and the previous regular expression used elsewhere (referred to as the previous scanning regular expression.) The previous regular expression can always be referred to by a null re, e.g. `//' or `??'.

8.2. Magic and nomagic

The regular expressions allowed by ex are constructed in one of two ways depending on the setting of the magic option. The ex and vi default setting of magic gives quick access to a powerful set of regular expression metacharacters. The disadvantage of magic is that the user must remember that these metacharacters are magic and precede them with the character `' to use them as ``ordinary'' characters. With nomagic, the default for edit, regular expressions are much simpler, there being only two metacharacters. The power of the other metacharacters is still available by preceding the (now) ordinary character with a `'. Note that `' is thus always a metacharacter.

The remainder of the discussion of regular expressions assumes that that the setting of this option is magic.

8.3. Basic regular expression summary

The following basic constructs are used to construct magic mode regular expressions.

char An ordinary character matches itself. The characters `' at the beginning of a line, `$' at the end of line, `*' as any character other than the first, `.', `', `[', and ` ~ ' are not ordinary characters and must be escaped (preceded) by `' to be treated as such.
At the beginning of a pattern forces the match to succeed only at the beginning of a line.
$ At the end of a regular expression forces the match to succeed only at the end of the line.
. Matches any single character except the new-line character.
< Forces the match to occur only at the beginning of a ``variable'' or ``word''; that is, either at the beginning of a line, or just before a letter, digit, or underline and after a character not one of these.
> Similar to `<', but matching the end of a ``variable'' or ``word'', i.e. either the end of the line or before character which is neither a letter, nor a digit, nor the underline character.
[ string ] Matches any (single) character in the class defined by string. Most characters in string define themselves. A pair of characters separated by `-' in string defines the set of characters collating between the specified lower and upper bounds, thus `[a-z]' as a regular expression matches any (single) lower-case letter. If the first character of string is an `' then the construct matches those characters which it otherwise would not; thus `[a-z]' matches anything but a lower-case letter (and of course a newline). To place any of the characters `', `[', or `-' in string you must escape them with a preceding `'.

8.4. Combining regular expression primitives

The concatenation of two regular expressions matches the leftmost and then longest string which can be divided with the first piece matching the first regular expression and the second piece matching the second. Any of the (single character matching) regular expressions mentioned above may be followed by the character `*' to form a regular expression which matches any number of adjacent occurrences (including 0) of characters matched by the regular expression it follows.

The character ` ~ ' may be used in a regular expression, and matches the text which defined the replacement part of the last substitute command. A regular expression may be enclosed between the sequences `' and `)' with side effects in the substitute replacement patterns.

8.5. Substitute replacement patterns

The basic metacharacters for the replacement pattern are `&' and `~'; these are given as `&' and `~' when nomagic is set. Each instance of `&' is replaced by the characters which the regular expression matched. The metacharacter `~' stands, in the replacement pattern, for the defining text of the previous replacement pattern.

Other metasequences possible in the replacement pattern are always introduced by the escaping character `'. The sequence `\n' is replaced by the text matched by the n-th regular subexpression enclosed between `' and `)'.

The sequences `u' and `l' cause the immediately following character in the replacement to be converted to upper- or lower-case respectively if this character is a letter. The sequences `U' and `L' turn such conversion on, either until `E' or `e' is encountered, or until the end of the replacement pattern.

9. Option descriptions

autoindent, ai default: noai

Can be used to ease the preparation of structured program text. At the beginning of each append, change or insert command or when a new line is opened or created by an append, change, insert, or substitute operation within open or visual mode, ex looks at the line being appended after, the first line changed or the line inserted before and calculates the amount of white space at the start of the line. It then aligns the cursor at the level of indentation so determined.
If the user then types lines of text in, they will continue to be justified at the displayed indenting level. If more white space is typed at the beginning of a line, the following line will start aligned with the first non-white character of the previous line. To back the cursor up to the preceding tab stop one can hit ^D. The tab stops going backwards are defined at multiples of the shiftwidth option. You cannot backspace over the indent, except by sending an end-of-file with a ^D.
Specially processed in this mode is a line with no characters added to it, which turns into a completely blank line (the white space provided for the autoindent is discarded.) Also specially processed in this mode are lines beginning with an `' and immediately followed by a ^D. This causes the input to be repositioned at the beginning of the line, but retaining the previous indent for the next line. Similarly, a `0' followed by a ^D repositions at the beginning but without retaining the previous indent.
Autoindent doesn't happen in global commands or when the input is not a terminal.

autoprint, ap default: ap

Causes the current line to be printed after each delete, copy, join, move, substitute, t, undo or shift command. This has the same effect as supplying a trailing `p' to each such command. Autoprint is suppressed in globals, and only applies to the last of many commands on a line.

autowrite, aw default: noaw

Causes the contents of the buffer to be written to the current file if you have modified it and give a next, rewind, stop, tag, or ! command, or a ^ (switch files) or ^] (tag goto) command in visual. Note, that the edit and ex commands do not autowrite. In each case, there is an equivalent way of switching when autowrite is set to avoid the autowrite (edit for next, rewind! for .I rewind , stop! for stop, tag! for tag, shell for !, and :e # and a :ta! command from within visual).

beautify, bf default: nobeautify

Causes all control characters except tab, newline and form-feed to be discarded from the input. A complaint is registered the first time a backspace character is discarded. Beautify does not apply to command input.

directory, dir default: dir=/tmp

Specifies the directory in which ex places its buffer file. If this directory in not writable, then the editor will exit abruptly when it fails to be able to create its buffer there.

edcompatible default: noedcompatible

Causes the presence of absence of g and c suffixes on substitute commands to be remembered, and to be toggled by repeating the suffices. The suffix r makes the substitution be as in the ~ command, instead of like &.

errorbells, eb default: noeb

Error messages are preceded by a bell.*

If possible the editor always places the error message in a standout mode of the terminal (such as inverse video) instead of ringing the bell.

hardtabs, ht default: ht=8

Gives the boundaries on which terminal hardware tabs are set (or on which the system expands tabs).

ignorecase, ic default: noic

All upper case characters in the text are mapped to lower case in regular expression matching. In addition, all upper case characters in regular expressions are mapped to lower case except in character class specifications.

lisp default: nolisp

Autoindent indents appropriately for lisp code, and the ( ) { } [[ and ]] commands in open and visual are modified to have meaning for lisp.

list default: nolist

All printed lines will be displayed (more) unambiguously, showing tabs and end-of-lines as in the list command.

magic default: magic for ex and vi

If nomagic is set, the number of regular expression metacharacters is greatly reduced, with only `' and `$' having special effects. In addition the metacharacters `~' and `&' of the replacement pattern are treated as normal characters. All the normal metacharacters may be made magic when nomagic is set by preceding them with a `'.

mesg default: mesg

Causes write permission to be turned off to the terminal while you are in visual mode, if nomesg is set.

modeline default: nomodeline

If modeline is set, then the first 5 lines and the last five lines of the file will be checked for ex command lines and the comands issued. To be recognized as a command line, the line must have the string ex: or vi: preceeded by a tab or a space. This string may be anywhere in the line and anything after the : is interpeted as editor commands. This option defaults to off because of unexpected behavior when editting files such as /etc/passwd.

number, nu default: nonumber

Causes all output lines to be printed with their line numbers. In addition each input line will be prompted for by supplying the line number it will have.

open default: open

If noopen, the commands open and visual are not permitted. This is set for edit to prevent confusion resulting from accidental entry to open or visual mode.

optimize, opt default: optimize

Throughput of text is expedited by setting the terminal to not do automatic carriage returns when printing more than one (logical) line of output, greatly speeding output on terminals without addressable cursors when text with leading white space is printed.

paragraphs, para default: para=IPLPPPQPP LIbp

Specifies the paragraphs for the { and } operations in open and visual. The pairs of characters in the option's value are the names of the macros which start paragraphs.

prompt default: prompt

Command mode input is prompted for with a `:'.

redraw default: noredraw

The editor simulates (using great amounts of output), an intelligent terminal on a dumb terminal (e.g. during insertions in visual the characters to the right of the cursor position are refreshed as each input character is typed.) Useful only at very high speed.

remap default: remap

If on, macros are repeatedly tried until they are unchanged. For example, if o is mapped to O, and O is mapped to I, then if remap is set, o will map to I, but if noremap is set, it will map to O.

report default: report=5

Specifies a threshold for feedback from commands. Any command which modifies more than the specified number of lines will provide feedback as to the scope of its changes. For commands such as global, open, undo, and visual which have potentially more far reaching scope, the net change in the number of lines in the buffer is presented at the end of the command, subject to this same threshold. Thus notification is suppressed during a global command on the individual commands performed.

scroll default: scroll= window

Determines the number of logical lines scrolled when an end-of-file is received from a terminal input in command mode, and the number of lines printed by a command mode z command (double the value of scroll).

sections default: sections=SHNHH HU

Specifies the section macros for the [[ and ]] operations in open and visual. The pairs of characters in the options's value are the names of the macros which start paragraphs.

shell, sh default: sh=/bin/sh

Gives the path name of the shell forked for the shell escape command `!', and by the shell command. The default is taken from SHELL in the environment, if present.

shiftwidth, sw default: sw=8

Gives the width a software tab stop, used in reverse tabbing with ^D when using autoindent to append text, and by the shift commands.

showmatch, sm default: nosm

In open and visual mode, when a ) or } is typed, move the cursor to the matching ( or { for one second if this matching character is on the screen. Extremely useful with lisp.

slowopen, slow terminal dependent

Affects the display algorithm used in visual mode, holding off display updating during input of new text to improve throughput when the terminal in use is both slow and unintelligent. See An Introduction to Display Editing with Vi for more details.

tabstop, ts default: ts=8

The editor expands tabs in the input file to be on tabstop boundaries for the purposes of display.

taglength, tl default: tl=0

Tags are not significant beyond this many characters. A value of zero (the default) means that all characters are significant.

tags default: tags=tags /usr/lib/tags

A path of files to be used as tag files for the tag command. A requested tag is searched for in the specified files, sequentially. By default, files called tags are searched for in the current directory and in /usr/lib (a master file for the entire system).

term from environment TERM

The terminal type of the output device.

terse default: noterse

Shorter error diagnostics are produced for the experienced user.

warn default: warn

Warn if there has been `[No write since last change]' before a `!' command escape.

window default: window=speed dependent

The number of lines in a text window in the visual command. The default is 8 at slow speeds (600 baud or less), 16 at medium speed (1200 baud), and the full screen (minus one line) at higher speeds.

w300, w1200 w9600

These are not true options but set window only if the speed is slow (300), medium (1200), or high (9600), respectively. They are suitable for an EXINIT and make it easy to change the 8/16/full screen rule.

wrapscan, ws default: ws

Searches using the regular expressions in addressing will wrap around past the end of the file.

wrapmargin, wm default: wm=0

Defines a margin for automatic wrapover of text during input in open and visual modes. See An Introduction to Text Editing with Vi for details.

writeany, wa default: nowa

Inhibit the checks normally made before write commands, allowing a write to any file which the system protection mechanism will allow.

Ex/Edit Command Summary (Version 2.0)

Ex and edit are text editors, used for creating and modifying files of text on the UNIX computer system. Edit is a variant of ex with features designed to make it less complicated to learn and use. In terms of command syntax and effect the editors are essentially identical, and this command summary applies to both.

The summary is meant as a quick reference for users already acquainted with edit or ex. Fuller explanations of the editors are available in the documents Edit: A Tutorial (a self-teaching introduction) and the Ex Reference Manual (the comprehensive reference source for both edit and ex). Both of these writeups are available in the Computing Services Library.

In the examples included with the summary, commands and text entered by the user are printed in boldface to distinguish them from responses printed by the computer.

The Editor Buffer

In order to perform its tasks the editor sets aside a temporary work space, called a buffer, separate from the user's permanent file. Before starting to work on an existing file the editor makes a copy of it in the buffer, leaving the original untouched. All editing changes are made to the buffer copy, which must then be written back to the permanent file in order to update the old version. The buffer disappears at the end of the editing session.

Editing: Command and Text Input Modes

During an editing session there are two usual modes of operation: command mode and text input mode. (This disregards, for the moment, open and visual modes, discussed below.) In command mode, the editor issues a colon prompt (:) to show that it is ready to accept and execute a command. In text input mode, on the other hand, there is no prompt and the editor merely accepts text to be added to the buffer. Text input mode is initiated by the commands append, insert, and change, and is terminated by typing a period as the first and only character on a line.

Line Numbers and Command Syntax

The editor keeps track of lines of text in the buffer by numbering them consecutively starting with 1 and renumbering as lines are added or deleted. At any given time the editor is positioned at one of these lines; this position is called the current line. Generally, commands that change the contents of the buffer print the new current line at the end of their execution.

Most commands can be preceded by one or two line-number addresses which indicate the lines to be affected. If one number is given the command operates on that line only; if two, on an inclusive range of lines. Commands that can take line-number prefixes also assume default prefixes if none are given. The default assumed by each command is designed to make it convenient to use in many instances without any line-number prefix. For the most part, a command used without a prefix operates on the current line, though exceptions to this rule should be noted. The print command by itself, for instance, causes one line, the current line, to be printed at the terminal.

The summary shows the number of line addresses that can be prefixed to each command as well as the defaults assumed if they are omitted. For example, (.,.) means that up to 2 line-numbers may be given, and that if none is given the command operates on the current line. (In the address prefix notation, ``.'' stands for the current line and ``$'' stands for the last line of the buffer.) If no such notation appears, no line-number prefix may be used.

Some commands take trailing information; only the more important instances of this are mentioned in the summary.

Open and Visual Modes

Besides command and text input modes, ex and edit provide on some CRT terminals other modes of editing, open and visual. In these modes the cursor can be moved to individual words or characters in a line. The commands then given are very different from the standard editor commands; most do not appear on the screen when typed. An Introduction to Display Editing with Vi provides a full discussion.

Special Characters

Some characters take on special meanings when used in context searches and in patterns given to the substitute command. For edit, these are ``^'' and ``$'', meaning the beginning and end of a line, respectively. Ex has the following additional special characters:

. & * [ ] ~

To use one of the special characters as its simple graphic representation rather than with its special meaning, precede it by a backslash (). The backslash always has a special meaning.

SYNOPSIS

ex [-eFRrSsv] [-c cmd] [-t tag] [-w size] [file ...]
vi [-eFlRrSv] [-c cmd] [-t tag] [-w size] [file ...]
view [-eFRrSv] [-c cmd] [-t tag] [-w size] [file ...]

LICENSE

The vi program is freely redistributable. You are welcome to copy, modify and share it with others under the conditions listed in the LICENSE file. If any company (not individual!) finds vi sufficiently useful that you would have purchased it, or if any company wishes to redistribute it, contributions to the authors would be appreciated.

DESCRIPTION

Vi is a screen oriented text editor. Ex is a line-oriented text editor. Ex and vi are different interfaces to the same program, and it is possible to switch back and forth during an edit session. View is the equivalent of using the -R (read-only) option of vi.
This manual page is the one provided with the nex/nvi versions of the ex/vi text editors. Nex/nvi are intended as bug-for-bug compatible replacements for the original Fourth Berkeley Software Distribution (4BSD) ex and vi programs. For the rest of this manual page, nex/nvi is used only when it's necessary to distinguish it from the historic implementations of ex/vi.
This manual page is intended for users already familiar with ex/vi. Anyone else should almost certainly read a good tutorial on the editor before this manual page. If you're in an unfamiliar environment, and you absolutely have to get work done immediately, read the section after the options description, entitled ``Fast Startup''. It's probably enough to get you going.
The following options are available:
-c
Execute cmd immediately after starting the edit session. Particularly useful for initial positioning in the file, however cmd is not limited to positioning commands. This is the POSIX 1003.2 interface for the historic ``+cmd'' syntax. Nex/nvi supports both the old and new syntax.
-e
Start editing in ex mode, as if the command name were ex.
-F
Don't copy the entire file when first starting to edit. (The default is to make a copy in case someone else modifies the file during your edit session.)
-l
Start editing with the lisp and showmatch options set.
-R
Start editing in read-only mode, as if the command name was view, or the readonly option was set.
-r
Recover the specified files, or, if no files are specified, list the files that could be recovered. If no recoverable files by the specified name exist, the file is edited as if the -r option had not been specified.
-S
Run with the secure edit option set, disallowing all access to external programs.
-s
Enter batch mode; applicable only to ex edit sessions. Batch mode is useful when running ex scripts. Prompts, informative messages and other user oriented message are turned off, and no startup files or environmental variables are read. This is the POSIX 1003.2 interface for the historic ``-'' argument. Nex/nvi supports both the old and new syntax.
-t
Start editing at the specified tag. (See ctags(1)).
-w
Set the initial window size to the specified number of lines.
-v
Start editing in vi mode, as if the command name was vi or view.
Command input for ex/vi is read from the standard input. In the vi interface, it is an error if standard input is not a terminal. In the ex interface, if standard input is not a terminal, ex will read commands from it regardless, however, the session will be a batch mode session, exactly as if the -s option had been specified.
Ex/vi exits 0 on success, and greater than 0 if an error occurs.

FAST STARTUP

This section will tell you the minimum amount that you need to do simple editing tasks using vi. If you've never used any screen editor before, you're likely to have problems even with this simple introduction. In that case you should find someone that already knows vi and have them walk you through this section.
Vi is a screen editor. This means that it takes up almost the entire screen, displaying part of the file on each screen line, except for the last line of the screen. The last line of the screen is used for you to give commands to vi, and for vi to give information to you.
The other fact that you need to understand is that vi is a modeful editor, i.e. you are either entering text or you are executing commands, and you have to be in the right mode to do one or the other. You will be in command mode when you first start editing a file. There are commands that switch you into input mode. There is only one key that takes you out of input mode, and that is the <escape> key. (Key names are written using less-than and greater-than signs, e.g. <escape> means the ``escape'' key, usually labeled ``esc'' on your terminal's keyboard.) If you're ever confused as to which mode you're in, keep entering the <escape> key until vi beeps at you. (Generally, vi will beep at you if you try and do something that's not allowed. It will also display error messages.)
To start editing a file, enter the command ``vi file_name<carriage-return>''. The command you should enter as soon as you start editing is ``:set verbose showmode<carriage-return>''. This will make the editor give you verbose error messages and display the current mode at the bottom of the screen.
The commands to move around the file are:
h
Move the cursor left one character.
j
Move the cursor down one line.
k
Move the cursor up one line.
l
Move the cursor right one character.
<cursor-arrows>
The cursor arrow keys should work, too.
/text<carriage-return>
Search for the string ``text'' in the file, and move the cursor to its first character.
The commands to enter new text are:
a
Append new text, after the cursor.
i
Insert new text, before the cursor.
o
Open a new line below the line the cursor is on, and start entering text.
O
Open a new line above the line the cursor is on, and start entering text.
<escape>
Once you've entered input mode using the one of the a, i, O or o commands, use <escape> to quit entering text and return to command mode.
The commands to copy text are:
yy
Copy the line the cursor is on.
p
Append the copied line after the line the cursor is on.
The commands to delete text are:
dd
Delete the line the cursor is on.
x
Delete the character the cursor is on.
The commands to write the file are:
:w<carriage-return>
Write the file back to the file with the name that you originally used as an argument on the vi command line.
:w file_name<carriage-return>
Write the file back to the file with the name ``file_name''.
The commands to quit editing and exit the editor are:
:q<carriage-return>
Quit editing and leave vi (if you've modified the file, but not saved your changes, vi will refuse to quit).
:q!<carriage-return>
Quit, discarding any modifications that you may have made.
One final caution. Unusual characters can take up more than one column on the screen, and long lines can take up more than a single screen line. The above commands work on ``physical'' characters and lines, i.e. they affect the entire line no matter how many screen lines it takes up and the entire character no matter how many screen columns it takes up.

ENVIRONMENT VARIABLES

COLUMNS
The number of columns on the screen. This value overrides any system or terminal specific values. If the COLUMNS environmental variable is not set when ex/vi runs, or the columns option is explicitly reset by the user, ex/vi enters the value into the environment.
EXINIT
A list of ex startup commands, read if the variable NEXINIT is not set.
HOME
The user's home directory, used as the initial directory path for the startup ``$HOME/.nexrc'' and ``$HOME/.exrc'' files. This value is also used as the default directory for the vi cd command.
LINES
The number of rows on the screen. This value overrides any system or terminal specific values. If the LINES environmental variable is not set when ex/vi runs, or the lines option is explicitly reset by the user, ex/vi enters the value into the environment.
NEXINIT
A list of ex startup commands.
SHELL
The user's shell of choice (see also the shell option).
TERM
The user's terminal type. The default is the type ``unknown''. If the TERM environmental variable is not set when ex/vi runs, or the term option is explicitly reset by the user, ex/vi enters the value into the environment.
TMPDIR
The location used to stored temporary files (see also the directory edit option).

ASYNCHRONOUS EVENTS

SIGALRM
Vi/ex uses this signal for periodic backups of file modifications and to display ``busy'' messages when operations are likely to take a long time.
SIGHUP
SIGTERM
If the current buffer has changed since it was last written in its entirety, the editor attempts to save the modified file so it can be later recovered. See the vi/ex Reference manual section entitled ``Recovery'' for more information.
SIGINT
When an interrupt occurs, the current operation is halted, and the editor returns to the command level. If interrupted during text input, the text already input is resolved into the file as if the text input had been normally terminated.
SIGWINCH
The screen is resized. See the vi/ex Reference manual section entitled ``Sizing the Screen'' for more information.
SIGCONT
SIGQUIT
SIGTSTP
Vi/ex ignores these signals.

FILES

/bin/sh
The default user shell.
/etc/vi.exrc
System-wide vi startup file.
/tmp
Temporary file directory.
/var/tmp/vi.recover
The default recovery file directory.
$HOME/.nexrc
1st choice for user's home directory startup file.
$HOME/.exrc
2nd choice for user's home directory startup file.

HISTORY

The nex/nvi replacements for the ex/vi editor first appeared in 4.4BSD.

STANDARDS

Nex/nvi is close to IEEE Std1003.2 (``POSIX''). That document differs from historical ex/vi practice in several places; there are changes to be made on both sides.

Table of Contents

1 Description

Vi is a screen oriented text editor. Ex is a line-oriented text editor. Ex and vi are different interfaces to the same program, and it is possible to switch back and forth during an edit session. View is the equivalent of using the -R (read-only) option of vi .

This reference manual is the one provided with the nex/nvi versions of the ex/vi text editors. Nex/nvi are intended as bug-for-bug compatible replacements for the original Fourth Berkeley Software Distribution (4BSD) ex/vi programs. This reference manual is accompanied by a traditional-style manual page. That manual page describes the functionality found in ex/vi in far less detail than the description here. In addition, it describes the system interface to ex/vi, e.g. command line options, session recovery, signals, environmental variables, and similar things.

This reference is intended for users already familiar with ex/vi. Anyone else should almost certainly read a good tutorial on the editor first. If you are in an unfamiliar environment, and you absolutely have to get work done immediately, see the section entitled “Fast Startup” in the manual page. It is probably enough to get you started.

There are a few features in nex/nvi that are not found in historic versions of ex/vi. Some of the more interesting of those features are briefly described in the next section, entitled “Additional Features” . For the rest of this document, nex/nvi is used only when it is necessary to distinguish it from the historic implementations of ex/vi.

Future versions of this software will be periodically made available by anonymous ftp, and can be retrieved from ftp.cs.berkeley.edu, in the directory ucb/4bsd.

2 Additional Features in Nex/Nvi

There are a few features in nex/nvi that are not found in historic versions of ex/vi. Some of the more interesting of these are as follows:

  • 8-bit clean data, large lines, files

    Nex/nvi will edit any format file. Line lengths are limited by available memory, and file sizes are limited by available disk space. The vi text input mode command <control-X> can insert any possible character value into the text.

  • Background and foreground screens

    The bg command backgrounds the current screen, and the fg command foregrounds backgrounded screens. The display command can be used to list the background screens.

  • Command Editing

    You can enter a normal editing window on the collected commands that you've entered on the vi colon command-line, and then modify and/or execute the commands. See the cedit edit option for more information.

  • Displays

    The display command can be used to display the current buffers, the backgrounded screens, and the tags stack.

  • Extended Regular Expressions

    The extended option causes Regular Expressions to be interpreted as as Extended Regular Expressions, (i.e. egrep(1) style Regular Expressions).

  • File Name Completion

    It is possible to do file name completion and file name displays when entering commands on the vi colon command-line. See the filec option for more information.

  • Infinite undo

    Changes made during an edit session may be rolled backward and forward. A . command immediately after a u command continues either forward or backward depending on whether the u command was an undo or a redo.

  • Left-right scrolling

    The leftright option causes nvi to do left-right screen scrolling, instead of the traditional vi line wrapping.

  • Message Catalogs

    It is possible to display informational and error messages in different languages by providing a catalog of messages. See the msgcat option and the file catalog/READMEfor more information.

  • Incrementing numbers

    The # command increments or decrements the number referenced by the cursor.

  • Previous file

    The previous command edits the previous file from the argument list.

  • Scripting languages

    The :pe[rl] cmd, :perld[o] cmd and :tc[l] cmd commands execute Perl and Tcl/Tk commands, respectively, on lines from the edit buffer. See the “Scripting Languages” section and the specific commands for more information.

  • Split screens

    The Edit , Ex , Next , Previous , Tag and Visual (in vi mode) commands divide the screen into multiple editing regions and then perform their normal function in a new screen area. The <control-W> command rotates between the foreground screens. The resize command can be used to grow or shrink a particular screen.

  • Tag stacks

    Tags are now maintained in a stack. The <control-T> command returns to the previous tag location. The tagpop command returns to the most recent tag location by default, or, optionally to a specific tag number in the tag stack, or the most recent tag from a specified file. The display command can be used to list the tags stack. The tagtop command returns to the top of the tag stack.

  • Usage information

    The exusage and viusage commands provide usage information for all of the ex and vi commands by default, or, optionally, for a specific command or key.

  • Word search

    The <control-A> command searches for the word referenced by the cursor.

3 Startup Information

Ex/vi interprets one of two possible environmental variables and reads up to three of five possible files during startup. The variables and files are expected to contain ex commands, not vi commands. In addition, they are interpreted before the file to be edited is read, and therefore many ex commands may not be used. Generally, any command that requires output to the screen or that needs a file upon which to operate, will cause an error if included in a startup file or environmental variable.

Because the ex command set supported by nex/nvi is a superset of the command set supported by historical implementations of ex , nex/nvi can use the startup files created for the historical implementations, but the converse may not be true.

If the -s (the historic - option) is specified, or if standard input is redirected from a file, all environmental variables and startup files are ignored.

Otherwise, startup files and environmental variables are handled in the following order:

  1. The file /etc/vi.exrcis read, as long as it is owned by root or the effective user ID of the user.
  2. The environmental variable NEXINIT(or the variable EXINIT, if NEXINITis not set) is interpreted.
  3. If neither NEXINITor EXINITwas set, and the HOMEenvironmental variable is set, the file $HOME/.nexrc(or the file $HOME/.exrc, if $HOME/.nexrcdoes not exist) is read, as long as the effective user ID of the user is root or is the same as the owner of the file.
    When the $HOME directory is being used for both nex/nvi and an historic implementation of ex/vi, a possible solution is to put nex/nvi specific commands in the .nexrcfile, along with a :source $HOME/.exrc command to read in the commands common to both implementations.
  4. If the exrc option was turned on by one of the previous startup information sources, the file .nexrc(or the file .exrc, if .nexrcdoes not exist) is read, as long as the effective user ID of the user is the same as the owner of the file.

No startup file is read if it is writable by anyone other than its owner.

It is not an error for any of the startup environmental variables or files not to exist.

Once all environmental variables are interpreted, and all startup files are read, the first file to be edited is read in (or a temporary file is created). Then, any commands specified using the -c option are executed, in the context of that file.

4 Recovery

There is no recovery program for nex/nvi, nor does nex/nvi run setuid. Recovery files are created readable and writable by the owner only. Users may recover any file which they can read, and the superuser may recover any edit session.

Edit sessions are backed by files in the directory named by the recdir option (the directory /var/tmp/vi.recoverby default), and are named “vi.XXXXXX”, where “XXXXXX” is a number related to the process ID. When a file is first modified, a second recovery file containing an email message for the user is created, and is named “recover.XXXXXX”, where, again, “XXXXXX” is associated with the process ID. Both files are removed at the end of a normal edit session, but will remain if the edit session is abnormally terminated or the user runs the ex preserve command.

The recdir option may be set in either the user's or system's startup information, changing the recovery directory. (Note, however, that if a memory based file system is used as the backup directory, each system reboot will delete all of the recovery files! The same caution applies to directories such as /tmpwhich are cleared of their contents by a system reboot, or /usr/tmpwhich is periodically cleared of old files on many systems.)

The recovery directory should be owned by root, or at least by a pseudo-user. In addition, if directory “sticky-bit” semantics are available, the directory should have the sticky-bit set so that files may only be removed by their owners. The recovery directory must be read, write, and executable by any user, i.e. mode 1777.

If the recovery directory does not exist, ex/vi will attempt to create it. This can result in the recovery directory being owned by a normal user, which means that that user will be able to remove other user's recovery and backup files. This is annoying, but is not a security issue as the user cannot otherwise access or modify the files.

The recovery file has all of the necessary information in it to enable the user to recover the edit session. In addition, it has all of the necessary email headers for sendmail(8). When the system is rebooted, all of the files in /var/tmp/vi.recovernamed “recover.XXXXXX” should be sent to their owners, by email, using the -t option of sendmail (or a similar mechanism in other mailers). If ex/vi receives a hangup (SIGHUP) signal, or the user executes the ex preserve command, ex/vi will automatically email the recovery information to the user.

If your system does not have the sendmail utility (or a mailer program which supports its interface) the source file nvi/common/recover.cwill have to be modified to use your local mail delivery programs. Note, if nex/nvi is changed to use another mailer, it is important to remember that the owner of the file given to the mailer is the nex/nvi user, so nothing in the file should be trusted as it may have been modified in an effort to compromise the system.

Finally, the owner execute bit is set on backup files when they are created, and unset when they are first modified, e.g. backup files that have no associated email recovery file will have this bit set. (There is also a small window where empty files can be created and not yet have this bit set. This is due to the method in which the files are created.) Such files should be deleted when the system reboots.

A simple way to do this cleanup is to run the Bourne shell script recover , from your /etc/rc.local(or other system startup) file. The script should work with the historic Bourne shell, a POSIX 1003.2 shell or the Korn shell. The recover script is installed as part of the nex/nvi installation process.

Consult the manual page for details on recovering preserved or aborted editing sessions.

5 Sizing the Screen

The size of the screen can be set in a number of ways. Ex/vi takes the following steps until values are obtained for both the number of rows and number of columns in the screen.

  1. If the environmental variable LINESexists, it is used to specify the number of rows in the screen.
  2. If the environmental variable COLUMNSexists, it is used to specify the number of columns in the screen.
  3. The TIOCGWINSZ ioctl(2) is attempted on the standard error file descriptor.
  4. The termcap entry (or terminfo entry on System V machines) is checked for the “li” entry (rows) and the “co” entry (columns).
  5. The number of rows is set to 24, and the number of columns is set to 80.

If a window change size signal (SIGWINCH) is received, the new window size is retrieved using the TIOCGWINSZ ioctl(2) call, and all other information is ignored.

6 Character Display

In both ex and vi printable characters as defined by isprint(3) are displayed using the local character set.

Non-printable characters, for which iscntrl(3) returns true, and which are less than octal \e040, are displayed as the string “^<character>”, where <character>is the character that is the original character's value offset from the “@” character. For example, the octal character \e001 is displayed as “^A”. If iscntrl(3) returns true for the octal character \e177, it is displayed as the string “^?”. All other characters are displayed as either hexadecimal values, in the form “0x<high-halfbyte> ... 0x<low-halfbyte>”, or as octal values, in the form “e<high-one-or-two-bits> ... e<low-three-bits>”. The display of unknown characters is based on the value of the octal option.

In vi command mode, the cursor is always positioned on the last column of characters which take up more than one column on the screen. In vi text input mode, the cursor is positioned on the first column of characters which take up more than one column on the screen.

7 Multiple Screens

Nvi supports multiple screens by dividing the window into regions. It also supports stacks of screens by permitting the user to change the set of screens that are currently displayed.

The Edit , Ex , Fg , Next , Previous , Tag and Visual (in vi mode) commands divide the current screen into two regions of approximately equal size and then perform their usual action in a new screen area. If the cursor is in the lower half of the screen, the screen will split up, i.e. the new screen will be above the old one. If the cursor is in the upper half of the screen, the new screen will be below the old one.

When more than one screen is editing a file, changes in any screen are reflected in all other screens editing the same file. Exiting a screen without saving any changes (or explicitly discarding them) is permitted until the last screen editing the file is exited, at which time the changes must be saved or discarded.

The resize command permits resizing of individual screens. Screens may be grown, shrunk or set to an absolute number of rows.

The ^W command is used to switch between screens. Each ^W moves to the next lower screen in the window, or to the first screen in the window if there are no lower screens.

The bg command “backgrounds” the current screen. The screen disappears from the window, and the rows it occupied are taken over by a neighboring screen. It is an error to attempt to background the only screen in the window.

The display screens command displays the names of the files associated with the current backgrounded screens in the window.

The fg [file] command moves the specified screen from the list of backgrounded screens to the foreground. If no file argument is specified, the first screen on the list is foregrounded. By default, foregrounding consists of backgrounding the current screen, and replacing its space in the window with the foregrounded screen.

Capitalizing the first letter of the command, i.e. Fg , will foreground the backgrounded screen in a new screen instead of swapping it with the current screen.

If the last foregrounded screen in the window is exited, and there are backgrounded screens, the first screen on the list of backgrounded screens takes over the window.

8 Tags, Tag Stacks, and Cscope

Nvi supports the historic vi tag command <control-]> , and the historic ex tag command tag . These commands change the current file context to a new location, based on information found in the tagsfiles. If you are unfamiliar with these commands, you should review their description in the ex and vi commands section of this manual. For additional information on tags files, see the discussion of the tags edit option and the system ctags(1) manual page.

In addition, nvi supports the notion of “tags stacks”, using the <control-T> command. The <control-T> command returns the user to the previous context, i.e., the last place from which a <control-]> or tag command was entered. These three commands provide the basic functionality which allows you to use vi to review source code in a structured manner.

Nvi also provides two other basic ex commands for tag support: tagpop and tagtop . The tagpop command is identical to the <control-T> command, with the additional functionality that you may specify that modifications to the current file are to be discarded. This cannot be done using the <control-T> command. The tagtop command discards all of the contexts that have been pushed onto the tag stack, returning to the context from which the first <control-]> or tag command was entered.

The historic ctags(1) tags file format supports only a single location per tag, normally the function declaration or structure or string definition. More sophisticated source code tools often provide multiple locations per tag, e.g., a list of the places from which a function is called or a string definition is used. An example of this functionality is the System V source code tool, cscope .
Cscope creates a database of information on source code files, and supports a query language for that information as described in the cscope(1) manual page. Nvi contains an interface to the cscope query language which permits you to query cscope and then sequentially step through the locations in the sources files which cscope returns. There are two nvi commands which support this ability to step through multiple locations. They are the ex commands tagnext and tagprev . The tagnext command moves to the next location for the current tag. The tagprev command moves to the previous location for the current tag. (See the tagnext and tagprev command discussion in the ex commands section of this manual for more information.) At any time during this sequential walk, you may use the <control-]> , tag or cscope commands to move to a new tag context, and then use the <control-T> or tagpop commands to return and continue stepping through the locations for this tag. This is similar to the previous model of a simple tag stack, except that each entry in the tag stack may have more than one file context that is of interest.

Although there is no widely distributed version of ctags(1) that creates tags files with multiple locations per tag, nvi has been written to understand the obvious extension to the historic tags file format, i.e., more than a single line in the tags file with the same initial tag name. If you wish to extend your ctags implementation or other tool with which you build tags files, this extension should be simple and will require no changes to nvi .

The nvi and cscope interface is based on the new ex command cscope , which has five subcommands: add , find , help , kill and reset . The subcommand find itself has eight subcommands: c , d , e , f , g , i , s and t .

  • cs[cope] a[dd] file

    The add command attaches to the specified cscope database. The file name is expanded using the standard filename expansions. If file is a directory, the file “cscope.out” in that directory is used as the database.

    After nvi attaches to a new database, all subsequent cscope queries will be asked of that database. The result of any single query is the collection of response to the query from all of the attached databases.
    If the “CSCOPE_DIRS” environmental variable is set when nvi is run, it is expected to be a <colon> or <blank>-separated list of cscope databases or directories containing cscope databases, to which the user wishes to attach.
  • :cs[cope] f[ind] c|d|e|f|g|i|s|t buffer|pattern

    The find command is the cscope query command for nvi . For this command, nvi queries all attached cscope databases for the pattern. If the pattern is a double-quote character followed by a valid buffer name (e.g., "<character>" ), then the contents of the named buffer are used as the pattern. Otherwise, the pattern is a Regular Expression.
    The find command pushes the current location onto the tags stack, and switches to the first location resulting from the query, if the query returned at least one result.
    File names returned by the cscope query, if not absolute paths, are searched for relative to the directory where the cscope database is located. In addition, if the file “cscope.tpath” appears in the same directory as the cscope database, it is expected to contain a colon-separated list of directory names where files referenced by its associated cscope database may be found.
    The find subcommand is one of the following:
    c
    Find callers of the name.
    d
    Find all function calls made from name.
    e
    Find pattern.
    f
    Find files with name as substring.
    g
    Find definition of name.
    i
    Find files #including name.
    s
    Find all uses of name.
    t
    Find assignments to name.
  • :cs[cope] h[elp] [command]

    List the cscope commands, or optionally list usage help for any single cscope command.

  • :display c[onnections]

    Display the list of cscope databases to which nvi is currently connected.

  • :cs[cope] k[ill] #

    Disconnect from a specific cscope database. The connection number is the one displayed by the ex display connections command.

  • :cs[cope] r[eset]

    Disconnect from all attached cscope databases.

Cscope is not freely redistributable software, but is fairly inexpensive and easily available. To purchase a copy of cscope , see http://www.att.com/ssg/products/toolchest.html.

9 Regular Expressions and Replacement Strings

Regular expressions are used in line addresses, as the first part of the ex substitute , global , and v commands, and in search patterns.

The regular expressions supported by ex/vi are, by default, the Basic Regular Expressions (BRE's) described in the IEEE POSIX Standard 1003.2. The extended option causes all regular expressions to be interpreted as the Extended Regular Expressions (ERE's) described by the same standard. (See re_format(7) for more information.) Generally speaking, BRE's are the Regular Expressions found in ed(1) and grep(1), and ERE's are the Regular Expressions found in egrep(1).

The following is not intended to provide a description of Regular Expressions. The information here only describes strings and characters which have special meanings in the ex/vi version of RE's, or options which change the meanings of characters that normally have special meanings in RE's.

  1. An empty RE (e.g. “//” or “??” is equivalent to the last RE used.
  2. The construct “e<” matches the beginning of a word.
  3. The construct “e>” matches the end of a word.
  4. The character “~” matches the replacement part of the last substitute command.

When the magic option is not set, the only characters with special meanings are a “^” character at the beginning of an RE, a “$” character at the end of an RE, and the escaping character “e”. The characters “.”, “*”, “[” and “~” are treated as ordinary characters unless preceded by a “e”; when preceded by a “e” they regain their special meaning.

Replacement strings are the second part of a substitute command.

The character “&” (or “e&” if the magic option is not set) in the replacement string stands for the text matched by the RE that is being replaced. The character “~” (or “e~” if the magic option is not set) stands for the replacement part of the previous substitute command. It is only valid after a substitute command has been performed.

The string “e#”, where “#” is an integer value from 1 to 9, stands for the text matched by the portion of the RE enclosed in the “#”'th set of escaped parentheses, e.g. “e(” and “e)”. For example, “s/abce(.*e)def/e1/” deletes the strings “abc” and “def” from the matched pattern.

The strings “el”, “eu”, “eL” and “eU” can be used to modify the case of elements in the replacement string. The string “el” causes the next character to be converted to lowercase; the string “eu” behaves similarly, but converts to uppercase (e.g. s/abc/eU&/replaces the string abcwith ABC). The string “eL” causes characters up to the end of the string or the next occurrence of the strings “ee” or “eE” to be converted to lowercase; the string “eU” behaves similarly, but converts to uppercase.

If the entire replacement pattern is “%”, then the last replacement pattern is used again.

In vi , inserting a <control-M>into the replacement string will cause the matched line to be split into two lines at that point. (The <control-M>will be discarded.)

10 Scripting Languages

The nvi editor currently supports two scripting languages, Tcl/Tk and Perl. (Note that Perl4 isn't sufficient, and that the Perl5 used must be version 5.002 or later. See the “Building Nvi” section for more information.

The scripting language interface is still being worked on, therefore the following information is probably incomplete, probably wrong in cases, and likely to change. See the perl_apiand tcl_apisource directories for more information. As a quick reference, the following function calls are provided for both the Perl and Tcl interfaces. The Perl interface uses a slightly different naming convention, e.g. “viFindScreen” is named “VI::FindScreen”.

  • viFindScreen file

    Return the screenIdassociated with file.

  • viAppendLine screenId lineNumber text

    Append textas a new line after line number lineNumber, in the screen screenId.

  • viDelLine screenId lineNum

    Delete the line lineNumberfrom the screen screenId.

  • viGetLine screenId lineNumber

    Return the line lineNumberfrom the screen screenId.

  • viInsertLine screenId lineNumber text

    Insert textas a new line before line number lineNumberin the screen screenId.

  • viLastLine screenId

    Return the line number of the last line in the screen screenId.

11 General Editor Description

When ex or vi are executed, the text of a file is read (or a temporary file is created), and then all editing changes happen within the context of the copy of the file. No changes affect the actual file until the file is written out, either using a write command or another command which is affected by the autowrite option.

All files are locked (using the flock(2) or fcntl(2) interfaces) during the edit session, to avoid inadvertently making modifications to multiple copies of the file. If a lock cannot be obtained for a file because it is locked by another process, the edit session is read-only (as if the readonly option or the -R flag had been specified). If a lock cannot be obtained for other reasons, the edit session will continue, but the file status information (see the <control-G> command) will reflect this fact.

Both ex and vi are modeful editors, i.e. they have two modes, “command” mode and “text input” mode. The former is intended to permit you to enter commands which modifies already existing text. The latter is intended to permit you to enter new text. When ex first starts running, it is in command mode, and usually displays a prompt (see the prompt option for more information). The prompt is a single colon “:” character. There are three commands that switch ex into text input mode: append , change and insert . Once in input mode, entering a line containing only a single period “.” ends text input mode and returns to command mode, where the prompt is redisplayed.

When vi first starts running, it is in command mode as well. There are eleven commands that switch vi into text input mode: A , a , C , c , I , i , O , o , R , S and s . Once in input mode, entering an <escape>character ends text input mode and returns to command mode.

Ex/vi present three different interfaces to editing a file. Ex presents a line oriented interface. Vi presents a full screen display oriented interface, also known as “visual mode”. In addition, there is a third mode, “open mode”, which is line oriented, but supports cursor movement and editing within the displayed line, similarly to visual mode. Open mode is not yet implemented in nvi .

The following words have special meanings in both the ex and vi command descriptions:

  • <interrupt>

    The interrupt character is used to interrupt the current operation. Normally <control-C>, whatever character is set for the current terminal is used.

  • <literal-next>

    The literal next character is used to escape the subsequent character from any special meaning. This character is always <control-V>. If the terminal is not set up to do XON/XOFF flow control, then <control-Q>is used to mean literal next as well.

  • current pathname

    The pathname of the file currently being edited by vi. When the percent character “%” appears in a file name entered as part of an ex command argument, it is replaced by the current pathname. (The “%” character can be escaped by preceding it with a backslash.)

  • alternate pathname

    The name of the last file name mentioned in an ex command, or, the previous current pathname if the last file mentioned becomes the current file. When the hash mark character “#” appears in a file name entered as part of an ex command argument, it is replaced by the alternate pathname. (The “#” character can be escaped by preceding it with a backslash.)

  • buffer

    One of a number of named areas for saving copies of text. Commands that change or delete text can save the changed or deleted text into a specific buffer, for later use, if the command allows it (i.e. the ex change command cannot save the changed text in a named buffer). Buffers are named with a single character, preceded by a double quote, e.g. "<character>" in vi and without the double quote, e.g. <character>, in ex . (The double quote isn't necessary for ex because buffers names are denoted by their position in the command line.) Historic implementations of ex/vi limited <character>to the alphanumeric characters; nex/nvi permits the use of any character without another meaning in the position where a buffer name is expected.
    Buffers named by uppercase characters are the same as buffers named by lowercase characters, e.g. the buffer named by the English character “A” is the same as the buffer named by the character “a”, with the exception that, if the buffer contents are being changed (as with a text deletion or vi change command), the text is appended to the buffer, instead of replacing the current contents.
    The buffers named by the numeric characters (in English, “1” through “9”), are special. If a region of text including characters from more than one line, or a single line of text specified by using a line-oriented motion, is changed or deleted in the file using the vi change or delete commands, a copy of the text is placed into the numeric buffer “1”, regardless of the user specifying another buffer in which to save it. In addition, there are a few commands which, when used as a motionwith the vi change and delete commands, always copy the specified region of text into the numeric buffers regardless of the region including characters from more than one line. These commands are:

    <control-A> % ( )
    `<character> / ? N
    n { }
    Before this copy is done, the previous contents of buffer “1” are moved into buffer “2”, “2” into buffer “3”, and so on. The contents of buffer “9” are discarded. In vi , text may be explicitly stored into the numeric buffers. In this case, the buffer rotation described above occurs before the replacement of the buffer's contents. The numeric buffers are only available in visualand openmodes, and are not accessible by ex in any way, although changed and deleted text is still stored there while in ex mode.
    When a vi command synopsis shows both a [buffer]and a [count], they may be presented in any order.
    Finally, all buffers are either “line” or “character” oriented. All ex commands which store text into buffers are line oriented. Some vi commands which store text into buffers are line oriented, and some are character oriented; the description for each applicable vi command notes whether text copied into buffers using the command is line or character oriented. In addition, the vi command display buffers displays the current orientation for each buffer. Generally, the only importance attached to this orientation is that if the buffer is subsequently inserted into the text, line oriented buffers create new lines for each of the lines they contain, and character oriented buffers create new lines for any lines other than the first and last lines they contain. The first and last lines are inserted into the text at the current cursor position, becoming part of the current line. If there is more than one line in the buffer, however, the current line itself will be split.
  • unnamed buffer

    The unnamed buffer is a text storage area which is used by commands that use or operate on a buffer when no buffer is specified by the user. If the command stores text into a buffer, the text is stored into the unnamed buffer even if a buffer is also specified by the user. It is not possible to append text to the unnamed buffer. If text is appended to a named buffer, the named buffer contains both the old and new text, while the unnamed buffer contains only the new text. There is no way to explicitly reference the unnamed buffer.
    Historically, the contents of the unnamed buffer were discarded by many different commands, even ones that didn't store text into it. Nex/nvi never discards the contents of the unnamed buffer until new text replaces them.
  • whitespace

    The characters <tab> and <space>.

  • <carriage-return>

    The character represented by an ASCII <control-M>. This character is almost always treated identically to a <newline>character, but differs in that it can be escaped into the file text or into a command.

  • <newline>

    The character represented by an ASCII <control-J>. This character is almost always treated identically to a <control-M>character, but differs in that it cannot be escaped into the file text or into a command.

12 Vi Description

Vi takes up the entire screen to display the edited file, except for the bottom line of the screen. The bottom line of the screen is used to enter exp commands, and for vi error and informational messages. If no other information is being displayed, the default display can show the current cursor row and cursor column, an indication of whether the file has been modified, and the current mode of the editor. See the ruler and showmode options for more information.

Empty lines do not have any special representation on the screen, but lines on the screen that would logically come after the end of the file are displayed as a single tilde “~” character. To differentiate between empty lines and lines consisting of only whitespace characters, use the list option. Historically, implementations of vi have also displayed some lines as single asterisk “@” characters. These were lines that were not correctly displayed, i.e. lines on the screen that did not correspond to lines in the file, or lines that did not fit on the current screen. Nvi never displays lines in this fashion.

Vi is a modeful editor, i.e. it has two modes, “command” mode and “text input” mode. When vi first starts, it is in command mode. There are several commands that change vi into text input mode. The <escape>character is used to resolve the text input into the file, and exit back into command mode. In vi command mode, the cursor is always positioned on the last column of characters which take up more than one column on the screen. In vi text insert mode, the cursor is positioned on the first column of characters which take up more than one column on the screen.

When positioning the cursor to a new line and column, the type of movement is defined by the distance to the new cursor position. If the new position is close, the screen is scrolled to the new location. If the new position is far away, the screen is repainted so that the new position is on the screen. If the screen is scrolled, it is moved a minimal amount, and the cursor line will usually appear at the top or bottom of the screen. If the screen is repainted, the cursor line will appear in the center of the screen, unless the cursor is sufficiently close to the beginning or end of the file that this isn't possible. If the leftright option is set, the screen may be scrolled or repainted in a horizontal direction as well as in a vertical one.

A major difference between the historical vi presentation and nvi is in the scrolling and screen oriented position commands, <control-B>, <control-D>, <control-E>, <control-F>, <control-U>, <control-Y>, H, L and M. In historical implementations of vi, these commands acted on physical (as opposed to logical, or screen) lines. For lines that were sufficiently long in relation to the size of the screen, this meant that single line scroll commands might repaint the entire screen, scrolling or screen positioning commands might not change the screen or move the cursor at all, and some lines simply could not be displayed, even though vi would edit the file that contained them. In nvi, these commands act on logical, i.e. screen lines. You are unlikely to notice any difference unless you are editing files with lines significantly longer than a screen width.

Vi keeps track of the currently “most attractive” cursor position. Each command description (for commands that alter the current cursor position), specifies if the cursor is set to a specific location in the line, or if it is moved to the “most attractive cursor position”. The latter means that the cursor is moved to the cursor position that is horizontally as close as possible to the current cursor position. If the current line is shorter than the cursor position vi would select, the cursor is positioned on the last character in the line. (If the line is empty, the cursor is positioned on the first column of the line.) If a command moves the cursor to the most attractive position, it does not alter the current cursor position, and a subsequent movement will again attempt to move the cursor to that position. Therefore, although a movement to a line shorter than the currently most attractive position will cause the cursor to move to the end of that line, a subsequent movement to a longer line will cause the cursor to move back to the most attractive position.

In addition, the $ command makes the end of each line the most attractive cursor position rather than a specific column.

Each vi command described below notes where the cursor ends up after it is executed. This position is described in terms of characters on the line, i.e. “the previous character”, or, “the last character in the line”. This is to avoid needing to continually refer to on what part of the character the cursor rests.

The following words have special meaning for vi commands.

  • previous context

    The position of the cursor before the command which caused the last absolute movement was executed. Each vi command described in the next section that is considered an absolute movement is so noted. In addition, specifying any address to an ex command is considered an absolute movement.

  • motion

    A second vi command can be used as an optional trailing argument to the vi <, >, !, c, d, y, and (depending on the tildeop option) ~ commands. This command indicates the end of the region of text that's affected by the command. The motion command may be either the command character repeated (in which case it means the current line) or a cursor movement command. In the latter case, the region affected by the command is from the starting or stopping cursor position which comes first in the file, to immediately before the starting or stopping cursor position which comes later in the file. Commands that operate on lines instead of using beginning and ending cursor positions operate on all of the lines that are wholly or partially in the region. In addition, some other commands become line oriented depending on where in the text they are used. The command descriptions below note these special cases.
    The following commands may all be used as motion components for vi commands:

    <control-A> <control-H> <control-J> <control-M>
    <control-N> <control-P> <space> $
    % '<character> ( )
    + , - /
    0 ; ? B
    E F G H
    L M N T
    W [[ ]] ^
    _ `<character> b e
    f h j k
    l n t w
    { | }
    The optional count prefix available for some of the vi commands that take motion commands, or the count prefix available for the vi commands that are used as motion components, may be included and is always considered part of the motion argument. For example, the commands “c2w” and “2cw” are equivalent, and the region affected by the c command is two words of text. In addition, if the optional count prefix is specified for both the vi command and its motion component, the effect is multiplicative and is considered part of the motion argument. For example, the commands “4cw” and “2c2w” are equivalent, and the region affected by the c command is four words of text.
  • count

    A positive number used as an optional argument to most commands, either to give a size or a position (for display or movement commands), or as a repeat count (for commands that modify text). The count argument is always optional and defaults to 1 unless otherwise noted in the command description.
    When a vi command synopsis shows both a [buffer]and [count], they may be presented in any order.
  • word

    Generally, in languages where it is applicable, vi recognizes two kinds of words. First, a sequence of letters, digits and underscores, delimited at both ends by: characters other than letters, digits, or underscores, the beginning or end of a line, and the beginning or end of the file. Second, a sequence of characters other than letters, digits, underscores, or whitespace characters, delimited at both ends by: a letter, digit, underscore, or whitespace character, the beginning or end of a line, and the beginning or end of the file. For example, the characters “!@#abc$%^ ” contain three words: “!@#”, “abc” and “$%^”.
    Groups of empty lines (or lines containing only whitespace characters) are treated as a single word.
  • bigword

    A set of non-whitespace characters preceded and followed by whitespace characters or the beginning or end of the file or line. For example, the characters “!@#abc$%^ ” contain one bigword: “!@#abc$%^”.
    Groups of empty lines (or lines containing only whitespace characters) are treated as a single bigword.
  • paragraph

    An area of text that begins with either the beginning of a file, an empty line, or a section boundary, and continues until either an empty line, section boundary, or the end of the file.
    Groups of empty lines (or lines containing only whitespace characters) are treated as a single paragraph.
    Additional paragraph boundaries can be defined using the paragraphs option.
  • section

    An area of text that starts with the beginning of the file or a line whose first character is an open brace “{” and continues until the next section or the end of the file.
    Additional section boundaries can be defined using the sections option.
  • sentence

    An area of text that begins with either the beginning of the file or the first nonblank character following the previous sentence, paragraph, or section boundary and continues until the end of the file or a period “.” exclamation point “!” or question mark “?” character, followed by either an end-of-line or two whitespace characters. Any number of closing parentheses “)”, brackets “]”, double-quote “"” or single quote “'” characters can appear between the period, exclamation point, or question mark and the whitespace characters or end-of-line.
    Groups of empty lines (or lines containing only whitespace characters) are treated as a single sentence.

    13 Vi Commands

The following section describes the commands available in the command mode of the vi editor. In each entry below, the tag line is a usage synopsis for the command character. In addition, the final line and column the cursor rests upon, and any options which affect the command are noted.

— Command: [count] <control-A>

Search forward counttimes for the current word. The current word begins at the first non-whitespace character on or after the current cursor position, and extends up to the next non-word character or the end of the line. The search is literal, i.e. no characters in the word have any special meaning in terms of Regular Expressions. It is an error if no matching pattern is found between the starting position and the end of the file.
The <control-A> command is an absolute movement. The <control-A> command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented.
Line:
Set to the line where the word is found.
Column:
Set to the first character of the word.
Options:
Affected by the ignorecase and wrapscan options.

— Command: [count] <control-B>

Page backward countscreens. Two lines of overlap are maintained, if possible, by displaying the window starting at line (top_line - count * window_size) + 2, where window_sizeis the value of the window option. (In the case of split screens, this size is corrected to the current screen size.) It is an error if the movement is past the beginning of the file.

Line:
Set to the last line of text displayed on the screen.
Column:
Set to the first nonblank character of the line.
Options:
Affected by the window option.

— Command: [count] <control-D>

Scroll forward countlines. If countis not specified, scroll forward the number of lines specified by the last <control-D> or <control-U> command. If this is the first <control-D> or <control-U> command, scroll forward half the number of lines in the screen. (In the case of split screens, the default scrolling distance is corrected to half the current screen size.) It is an error if the movement is past the end of the file.

Line:
Set to the current line plus the number of lines scrolled.
Column:
Set to the first nonblank character of the line.
Options:
None.

— Command: [count] <control-E>

Scroll forward countlines, leaving the cursor on the current line and column, if possible. It is an error if the movement is past the end of the file.

Line:
Unchanged unless the current line scrolls off the screen, in which case it is set to the first line on the screen.
Column:
Unchanged unless the current line scrolls off the screen, in which case it is set to the most attractive cursor position.
Options:
None.

— Command: [count] <control-F>

Page forward countscreens. Two lines of overlap are maintained, if possible, by displaying the window starting at line top_line + count * window_size - 2, where window_sizeis the value of the window option. (In the case of split screens, this size is corrected to the current screen size.) It is an error if the movement is past the end of the file.

Line:
Set to the first line on the screen.
Column:
Set to the first nonblank character of the current line.
Options:
Affected by the window option.

— Command: <control-G>

Display the file information. The information includes the current pathname, the current line, the number of total lines in the file, the current line as a percentage of the total lines in the file, if the file has been modified, was able to be locked, if the file's name has been changed, and if the edit session is read-only.

Line:
Unchanged.
Column:
Unchanged.
Options:
None.

— Command: [count] <control-H>
— Command: [count] h

Move the cursor back countcharacters in the current line. It is an error if the cursor is on the first character in the line.
The <control-H> and h commands may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented.
Line:
Unchanged.
Column:
Set to the current - countcharacter, or, the first character in the line if countis greater than or equal to the number of characters in the line before the cursor.
Options:
None.

— Command: [count] <control-J>

— Command: [count] <control-N>

— Command: [count] j

Move the cursor down countlines without changing the current column. It is an error if the movement is past the end of the file.
The <control-J>, <control-N> and j commands may be used as the motion component of other vi commands, in which case any text copied into a buffer is line oriented.
Line:
Set to the current line plus count.
Column:
The most attractive cursor position.
Options:
None.

— Command: <control-L>

— Command: <control-R>

Repaint the screen.

Line:
Unchanged.
Column:
Unchanged.
Options:
None.

— Command: [count] <control-M>

— Command: [count] +

Move the cursor down countlines to the first nonblank character of that line. It is an error if the movement is past the end of the file.
The <control-M> and + commands may be used as the motion component of other vi commands, in which case any text copied into a buffer is line oriented.
Line:
Set to the current line plus count.
Column:
Set to the first nonblank character in the line.
Options:
None.

— Command: [count] <control-P>

— Command: [count] k

Move the cursor up countlines, without changing the current column. It is an error if the movement is past the beginning of the file.
The <control-P> and k commands may be used as the motion component of other vi commands, in which case any text copied into a buffer is line oriented.
Line:
Set to the current line minus count.
Column:
The most attractive cursor position.
Options:
None.

— Command: <control-T>

Return to the most recent tag context. The <control-T> command is an absolute movement.

Line:
Set to the context of the previous tag command.
Column:
Set to the context of the previous tag command.
Options:
None.

— Command: [count] <control-U>

Scroll backward countlines. If countis not specified, scroll backward the number of lines specified by the last <control-D> or <control-U> command. If this is the first <control-D> or <control-U> command, scroll backward half the number of lines in the screen. (In the case of split screens, the default scrolling distance is corrected to half the current screen size.) It is an error if the movement is past the beginning of the file.

Line:
Set to the current line minus the amount scrolled.
Column:
Set to the first nonblank character in the line.
Options:
None.

— Command: <control-W>

Switch to the next lower screen in the window, or, to the first screen if there are no lower screens in the window.

Line:
Set to the previous cursor position in the window.
Column:
Set to the previous cursor position in the window.
Options:
None.

— Command: [count] <control-Y>

Scroll backward countlines, leaving the current line and column as is, if possible. It is an error if the movement is past the beginning of the file.

Line:
Unchanged unless the current line scrolls off the screen, in which case it is set to the last line of text displayed on the screen.
Column:
Unchanged unless the current line scrolls off the screen, in which case it is the most attractive cursor position.
Options:
None.

— Command: <control-Z>

Suspend the current editor session. If the file has been modified since it was last completely written, and the autowrite option is set, the file is written before the editor session is suspended. If this write fails, the editor session is not suspended.

Line:
Unchanged.
Column:
Unchanged.
Options:
Affected by the autowrite option.

— Command: <escape>

Execute ex commands or cancel partial commands. If an ex command is being entered (e.g. /, ?, : or !), the command is executed. If a partial command has been entered, e.g. “[0-9]*”, or “[0-9]*[!<>cdy]”, the command is cancelled. Otherwise, it is an error.

Line:
When an ex command is being executed, the current line is set as described for that command. Otherwise, unchanged.
Column:
When an ex command is being executed, the current column is set as described for that command. Otherwise, unchanged.
Options:
None.

— Command: <control-]>

Push a tag reference onto the tag stack. The tags files (see the tags option for more information) are searched for a tag matching the current word. The current word begins at the first non-whitespace character on or after the current cursor position, and extends up to the next non-word character or the end of the line. If a matching tag is found, the current file is discarded and the file containing the tag reference is edited.
If the current file has been modified since it was last completely written, the command will fail. The <control-]> command is an absolute movement.
Line:
Set to the line containing the matching tag string.
Column:
Set to the start of the matching tag string.
Options:
Affected by the tags and taglength options.

— Command: <control-^>

Switch to the most recently edited file.
If the file has been modified since it was last completely written, and the autowrite option is set, the file is written out. If this write fails, the command will fail. Otherwise, if the current file has been modified since it was last completely written, the command will fail.
Line:
Set to the line the cursor was on when the file was last edited.
Column:
Set to the column the cursor was on when the file was last edited.
Options:
Affected by the autowrite option.

— Command: [count] <space>

— Command: [count] l

Move the cursor forward countcharacters without changing the current line. It is an error if the cursor is on the last character in the line.
The <space> and l commands may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented. In addition, these commands may be used as the motion components of other commands when the cursor is on the last character in the line, without error.
Line:
Unchanged.
Column:
Set to the current character plus the next countcharacters, or to the last character on the line if countis greater than the number of characters in the line after the current character.
Options:
None.

— Command: [count] ! motion shell-argument(s)<carriage-return>

Replace text with results from a shell command. Pass the lines specified by the countand motionarguments as standard input to the program named by the shell option, and replace those lines with the output (both standard error and standard output) of that command.
After the motion is entered, vi prompts for arguments to the shell command.
Within those arguments, “%” and “#” characters are expanded to the current and alternate pathnames, respectively. The “!” character is expanded with the command text of the previous ! or :! commands. (Therefore, the command !<motion>! repeats the previous ! command.) The special meanings of “%”, “#” and “!” can be overridden by escaping them with a backslash. If no ! or :! command has yet been executed, it is an error to use an unescaped “!” character as a shell argument. The ! command does not do shell expansion on the strings provided as arguments. If any of the above expansions change the arguments the user entered, the command is redisplayed at the bottom of the screen.
Vi then executes the program named by the shell option, with a -c flag followed by the arguments (which are bundled into a single argument).
The ! command is permitted in an empty file.
If the file has been modified since it was last completely written, the ! command will warn you.
Line:
The first line of the replaced text.
Column:
The first column of the replaced text.
Options:
Affected by the shell option.

— Command: [count] # #|+|-

Increment or decrement the number referenced by the cursor. If the trailing character is a +or #, the number is incremented by count. If the trailing character is a -, the number is decremented by count.
A leading “0X” or “0x” causes the number to be interpreted as a hexadecimal number. Otherwise, a leading “0” causes the number to be interpreted as an octal number, unless a non-octal digit is found as part of the number. Otherwise, the number is interpreted as a decimal number, and may have a leading +or -sign. The current number begins at the first non-blank character at or after the current cursor position, and extends up to the end of the line or the first character that isn't a possible character for the numeric type. The format of the number (e.g. leading 0's, signs) is retained unless the new value cannot be represented in the previous format.
Octal and hexadecimal numbers, and the result of the operation, must fit into an “unsigned long”. Similarly, decimal numbers and their result must fit into a “signed long”. It is an error to use this command when the cursor is not positioned at a number.
Line:
Unchanged.
Column:
Set to the first character in the cursor number.
Options:
None.

— Command: [count] $

Move the cursor to the end of a line. If countis specified, the cursor moves down count - 1lines.
It is not an error to use the $ command when the cursor is on the last character in the line or when the line is empty.
The $ command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented, unless the cursor is at, or before the first nonblank character in the line, in which case it is line oriented. It is not an error to use the $ command as a motion component when the cursor is on the last character in the line, although it is an error when the line is empty.
Line:
Set to the current line plus countminus 1.
Column:
Set to the last character in the line.
Options:
None.

— Command: %

Move to the matching character. The cursor moves to the parenthesis or curly brace which matches the parenthesis or curly brace found at the current cursor position or which is the closest one to the right of the cursor on the line. It is an error to execute the % command on a line without a parenthesis or curly brace. Historically, any countspecified to the % command was ignored.
The % command is an absolute movement. The % command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented, unless the starting point of the region is at or before the first nonblank character on its line, and the ending point is at or after the last nonblank character on its line, in which case it is line oriented.
Line:
Set to the line containing the matching character.
Column:
Set to the matching character.
Options:
None.

— Command: &

Repeat the previous substitution command on the current line.
Historically, any countspecified to the & command was ignored.
Line:
Unchanged.
Column:
Unchanged if the cursor was on the last character in the line, otherwise, set to the first nonblank character in the line.
Options:
Affected by the edcompatible, extended, ignorecase and magic options.

— Command: '<character>

— Command: `<character>

Return to a context marked by the character <character>. If <character>is the “'” or “`” character, return to the previous context. If <character>is any other character, return to the context marked by that character (see the m command for more information). If the command is the ' command, only the line value is restored, and the cursor is placed on the first nonblank character of that line. If the command is the ` command, both the line and column values are restored.
It is an error if the context no longer exists because of line deletion. (Contexts follow lines that are moved, or which are deleted and then restored.)
The ' and ` commands are both absolute movements. They may be used as a motion component for other vi commands. For the ' command, any text copied into a buffer is line oriented. For the ` command, any text copied into a buffer is character oriented, unless it both starts and stops at the first character in the line, in which case it is line oriented. In addition, when using the ` command as a motion component, commands which move backward and started at the first character in the line, or move forward and ended at the first character in the line, are corrected to the last character of the line preceding the starting and ending lines, respectively.
Line:
Set to the line from the context.
Column:
Set to the first nonblank character in the line, for the ' command, and set to the context's column for the ` command.
Options:
None.

— Command: [count] (

Back up countsentences.
The ( command is an absolute movement. The ( command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented, unless the starting and stopping points of the region are the first character in the line, in which case it is line oriented. If it is line oriented, the starting point of the region is adjusted to be the end of the line immediately before the starting cursor position.
Line:
Set to the line containing the beginning of the sentence.
Column:
Set to the first nonblank character of the sentence.
Options:
Affected by the lisp option.

— Command: [count] )

Move forward countsentences.
The ) command is an absolute movement. The ) command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented, unless the starting point of the region is the first character in the line, in which case it is line oriented. In the latter case, if the stopping point of the region is also the first character in the line, it is adjusted to be the end of the line immediately before it.
Line:
Set to the line containing the beginning of the sentence.
Column:
Set to the first nonblank character of the sentence.
Options:
Affected by the lisp option.

— Command: [count] ,

Reverse find character counttimes. Reverse the last F, f, T or t command, searching the other way in the line, counttimes. It is an error if a F, f, T or t command has not been performed yet.
The , command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented.
Line:
Unchanged.
Column:
Set to the searched-for character for the F and f commands, before the character for the t command and after the character for the T command.
Options:
None.

— Command: [count] -

Move to the first nonblank of the previous line, counttimes.
It is an error if the movement is past the beginning of the file.
The - command may be used as the motion component of other vi commands, in which case any text copied into a buffer is line oriented.
Line:
Set to the current line minus count.
Column:
Set to the first nonblank character in the line.
Options:
None.

— Command: [count] .

Repeat the last vi command that modified text. The repeated command may be a command and motion component combination. If countis specified, it replaces both the count specified for the repeated command, and, if applicable, for the repeated motion component. If countis not specified, the counts originally specified to the command being repeated are used again.
As a special case, if the . command is executed immediately after the u command, the change log is rolled forward or backward, depending on the action of the u command.
Line:
Set as described for the repeated command.
Column:
Set as described for the repeated command.
Options:
None.

— Command: /RE<carriage-return>
— Command: /RE/ [

— Command: ?RE<carriage-return>
— Command: ?RE? [

— Command: N

— Command: n

Search forward or backward for a regular expression. The commands beginning with a slash “/” character are forward searches, the commands beginning with a question mark “?” are backward searches. Vi prompts with the leading character on the last line of the screen for a string. It then searches forward or backward in the file for the next occurrence of the string, which is interpreted as a Basic Regular Expression.
The / and ? commands are absolute movements. They may be used as the motion components of other vi commands, in which case any text copied into a buffer is character oriented, unless the search started and ended on the first column of a line, in which case it is line oriented. In addition, forward searches ending at the first character of a line, and backward searches beginning at the first character in the line, are corrected to begin or end at the last character of the previous line. (Note, forward and backward searches can occur for both / and ? commands, if the wrapscan option is set.)
If an offset from the matched line is specified (i.e. a trailing “/” or “?” character is followed by a signed offset), the buffer will always be line oriented (e.g. “/string/+0” will always guarantee a line orientation).
The N command repeats the previous search, but in the reverse direction. The n command repeats the previous search. If either the N or n commands are used as motion components for the ! command, you will not be prompted for the text of the bang command, instead the previous bang command will be executed.
Missing RE's (e.g. “//<carriage-return>”, “/<carriage-return>”, “??<carriage-return>”, or “?<carriage-return>” search for the last search RE, in the indicated direction.
Searches may be interrupted using the <interrupt>character.
Multiple search patterns may be grouped together by delimiting them with semicolons and zero or more whitespace characters, e.g. /foo/ ; ?bar?searches forward for fooand then, from that location, backwards for bar. When search patterns are grouped together in this manner, the search patterns are evaluated left to right with the final cursor position determined by the last search pattern.
It is also permissible to append a z command to the search strings, e.g. /foo/ z.searches forward for the next occurrence of foo, and then positions that line in the middle of screen.
Line:
Set to the line in which the match occurred.
Column:
Set to the first character of the matched string.
Options:
Affected by the edcompatible, extended, ignorecase, magic, and wrapscan options.

— Command: 0

Move to the first character in the current line. It is not an error to use the 0 command when the cursor is on the first character in the line,
The 0 command may be used as the motion component of other vi commands, in which case it is an error if the cursor is on the first character in the line, and any text copied into a buffer is character oriented.
Line:
Unchanged.
Column:
Set to the first character in the line.
Options:
None.

— Command: :

Execute an ex command. Vi prompts for an ex command on the last line of the screen, using a colon “:” character. The command is terminated by a <carriage-return>, <newline>or <escape>character; all of these characters may be escaped by using a <literal-next>character. The command is then executed.
If the ex command writes to the screen, vi will prompt the user for a <carriage-return>before continuing when the ex command finishes. Large amounts of output from the ex command will be paged for the user, and the user prompted for a <carriage-return>or <space>key to continue. In some cases, a quit (normally a “q” character) or <interrupt>may be entered to interrupt the ex command.
When the ex command finishes, and the user is prompted to resume visual mode, it is also possible to enter another “:” character followed by another ex command.
Line:
The current line is set as described for the ex command.
Column:
The current column is set as described for the ex command.
Options:
Affected as described for the ex command.

— Command: [count] ;

Repeat the last character find counttimes. The last character find is one of the F, f, T or t commands. It is an error if a F, f, T or t command has not been performed yet.
The ; command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented.
Line:
Unchanged.
Column:
Set to the searched-for character for the F and f commands, before the character for the t command and after the character for the T command.
Options:
None.

— Command: [count] < motion

— Command: [count] > motion

Shift lines left or right. Shift the number of lines in the region specified by the countand motionleft (for the < command) or right (for the > command) by the number of columns specified by the shiftwidth option. Only whitespace characters are deleted when shifting left. Once the first character in the line no longer contains a whitespace character, the command will succeed, but the line will not be modified.

Line:
Unchanged.
Column:
Set to the first nonblank character in the line.
Options:
Affected by the shiftwidth option.

— Command: @ buffer

Execute a named buffer. Execute the named buffer as vi commands. The buffer may include ex commands, too, but they must be expressed as a : command. If the buffer is line oriented, <newline>characters are logically appended to each line of the buffer. If the buffer is character oriented, <newline>characters are logically appended to all but the last line in the buffer.
If the buffer name is “@”, or “*”, then the last buffer executed shall be used. It is an error to specify “@@” or “@*” if there were no previous buffer executions. The text of a buffer may contain a @ command, and it is possible to create infinite loops in this manner. (The <interrupt>character may be used to interrupt the loop.)
Line:
The current line is set as described for the command(s).
Column:
The current column is set as described for the command(s).

If count1is specified, place the line count1at the top of the screen. Otherwise, display the screen after the current screen, similarly to the <control-F> command.
<carriage-return>
Place the line count1at the top of the screen.
.
Place the line count1in the center of the screen.
-
Place the line count1at the bottom of the screen.
^
If count1is specified, place the line that is at the top of the screen when count1is at the bottom of the screen, at the bottom of the screen, i.e. display the screen before the screen before count1. Otherwise, display the screen before the current screen, similarly to the <control-B> command.
Line:
Set to count1unless count1is not specified and the typecharacter was either “^” or “+”, in which case it is set to the line before the first line on the previous screen or the line after the last line on the previous screen, respectively.
Column:
Set to the first nonblank character in the line.
Options:
None.

— Command: [count] {

Move backward countparagraphs.
The { command is an absolute movement. The { command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented, unless the starting character is the first character on its line, in which case it is line oriented.
Line:
Set to the line containing the beginning of the previous paragraph.
Column:
Set to the first nonblank character in the line.
Options:
Affected by the paragraph option.

— Command: [count] |

Move to a specific column position on the current line.
The | command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented. It is an error to use the | command as a motion component and for the cursor not to move.
Line:
Unchanged.
Column:
Set to the character occupying the column position identified by count, if the position exists in the line. If the column length of the current line is less than count, the cursor is moved to the last character in the line.
Options:
None.

— Command: [count] }

Move forward countparagraphs.
The } command is an absolute movement. The } command may be used as the motion component of other vi commands, in which case any text copied into a buffer is character oriented, unless the starting character is at or before any nonblank characters in its line, in which case it is line oriented.
Line:
Set to the line containing the beginning of the next paragraph.
Column:
Set to the first nonblank character in the line.
Options:
Affected by the paragraph option.

— Command: [count] ~

Reverse the case of the next countcharacter(s). This is the historic semantic for the ~ command and it is only in effect if the tildeop option is not set.
Lowercase alphabetic characters are changed to uppercase, and uppercase characters are changed to lowercase. No other characters are affected.
Historically, the ~ command did not take an associated count, nor did it move past the end of the current line. As it had no associated motion it was difficult to change the case of large blocks of text. In nvi, if the cursor is on the last character of a line, and there are more lines in the file, the cursor moves to the next line.
It is not an error to specify a count larger than the number of characters between the cursor and the end of the file.
Line:
Set to the line of the character after countcharacters, or, end of file.
Column:
Set to the character after countcharacters, or, end-of-file.
Options:
Affected by the tildeop option.

— Command: [count] ~ motion

Reverse the case of the characters in a text region specified by the countand motion. Only in effect if the tildeop option is set.
Lowercase characters are changed to uppercase, and uppercase characters are changed to lowercase. No other characters are affected.
Line:
Set to the line of the character after the last character in the region.
Column:
Set to the character after the last character in the region.
Options:
Affected by the tildeop option.

— Command: <interrupt>

Interrupt the current operation. Many of the potentially long-running vi commands may be interrupted using the terminal interrupt character. These operations include searches, file reading and writing, filter operations and map character expansion. Interrupts are also enabled when running commands outside of vi.
If the <interrupt>character is used to interrupt while entering an ex command, the command is aborted, the cursor returns to its previous position, and vi remains in command mode.
Generally, if the <interrupt>character is used to interrupt any operation, any changes made before the interrupt are left in place.
Line:
Dependent on the operation being interrupted.
Column:
Dependent on the operation being interrupted.
Options:
None.

14 Vi Text Input Commands

The following section describes the commands available in the text input mode of the vi editor.

Historically, vi implementations only permitted the characters inserted on the current line to be erased. In addition, only the <control-D>erase character and the “0<control-D>” and “^<control-D>” erase strings could erase autoindent characters. (Autoindent characters include both the characters inserted automatically at the beginning of an input line as well as characters inserted using the <control-T>command.) This implementation permits erasure to continue past the beginning of the current line, and back to where text input mode was entered. In addition, autoindent characters may be erased using the standard erase characters. For the line and word erase characters, reaching the autoindent characters forms a “soft” boundary, denoting the end of the current word or line erase. Repeating the word or line erase key will erase the autoindent characters.

Historically, vi always used <control-H>and <control-W>as character and word erase characters, respectively, regardless of the current terminal settings. This implementation accepts, in addition to these two characters, the current terminal characters for those operations.

— Input: <nul>

If the first character of the input is a <nul>, the previous input is replayed, as if just entered.

— Input: <control-D>

If the previous character on the line was an autoindent character, erase characters to move the cursor back to the column immediately after the previous (1-based) column which is a multiple of the shiftwidth edit option. This may result in any number of <tab>and <space>characters preceding the cursor being changed.
Otherwise, if the autoindent option is set and the user is entering the first character in the line, <control-D>is ignored. Otherwise, a literal <control-D>character is entered.

— Input: ^<control-D>

If the previous character on the line was an autoindent character, erase all of the autoindent characters on the line. In addition, the autoindent level is reset to 0.

— Input: 0<control-D>

If the previous character on the line was an autoindent character, erase all of the autoindent characters on the line. The autoindent level is not altered.

— Input: <control-T>

Insert sufficient <tab>and <space>characters to move the cursor forward to the column immediately after the next (1-based) column which is a multiple of the shiftwidth edit option. This may result in any number of <tab>and <space>characters preceding the cursor being changed.
Historically, vi did not permit the <control-T>command to be used unless the cursor was at the first column of a new line or it was preceded only by autoindent characters. Nvi permits it to be used at any time during insert mode.

— Input: <erase>

— Input: <control-H>

Erase the last character.

— Input: <literal-next>

Quote the next character. The next character will not be mapped (see the map command for more information) or interpreted specially. A carat “^” character will be displayed immediately as a placeholder, but will be replaced by the next character.

— Input: <escape>

If on the colon command line, and the filec edit option is set, behave as described for that option. Otherwise, if on the colon command line, execute the command. Otherwise, if not on the colon command line, resolve all text input into the file, and return to command mode.

— Input: <line erase>

Erase the current line.

— Input: <control-W>

— Input: <word erase>

Erase the last word. The definition of word is dependent on the altwerase and ttywerase options.

— Input: <control-X>[0-9A-Fa-f]+

Insert a character with the specified hexadecimal value into the text. The value is delimited by any non-hexadecimal character or the input of the maximum number of characters that can be translated into a single character value.

— Input: <interrupt>

Interrupt text input mode, returning to command mode. If the <interrupt>character is used to interrupt inserting text into the file, it is as if the <escape>character was used; all text input up to the interruption is resolved into the file.

15 Ex Addressing

Addressing in ex (and when ex commands are executed from vi ) relates to the current line. In general, the current line is the last line affected by a command. The exact effect on the current line is discussed under the description of each command. When the file contains no lines, the current line is zero.

Addresses are constructed by one or more of the following methods:

  1. The address “.” refers to the current line.
  2. The address “$” refers to the last line of the file.
  3. The address “N”, where Nis a positive number, refers to the N-th line of the file.
  4. The address “'<character>” or “`<character>” refers to the line marked with the name <character>. (See the k or m commands for more information on how to mark lines.)
  5. A regular expression (RE) enclosed by slashes “/” is an address, and it refers to the first line found by searching forward from the line after the current line toward the end of the file, and stopping at the first line containing a string matching the RE. (The trailing slash can be omitted at the end of the command line.)
    If no RE is specified, i.e. the pattern is “//”, the last RE used in any command is used in the search.
    If the extended option is set, the RE is handled as an extended RE, not a basic RE. If the wrapscan option is set, the search wraps around to the beginning of the file and continues up to and including the current line, so that the entire file is searched.
    The form “e/” is accepted for historic reasons, and is identical to “//”.
  6. An RE enclosed in question marks “?” addresses the first line found by searching backward from the line preceding the current line, toward the beginning of the file and stopping at the first line containing a string matching the RE. (The trailing question mark can be omitted at the end of a command line.)
    If no RE is specified, i.e. the pattern is “??”, the last RE used in any command is used in the search.
    If the extended option is set, the RE is handled as an extended RE, not a basic RE. If the wrapscan option is set, the search wraps around from the beginning of the file to the end of the file and continues up to and including the current line, so that the entire file is searched.
    The form “e?” is accepted for historic reasons, and is identical to “??”.
  7. An address followed by a plus sign “+” or a minus sign “-” followed by a number is an offset address and refers to the address plus (or minus) the indicated number of lines. If the address is omitted, the addition or subtraction is done with respect to the current line.
  8. An address of “+” or “-” followed by a number is an offset from the current line. For example, “-5” is the same as “.-5”.
  9. An address ending with “+” or “-” has 1 added to or subtracted from the address, respectively. As a consequence of this rule and of the previous rule, the address “-” refers to the line preceding the current line. Moreover, trailing “+” and “-” characters have a cumulative effect. For example, “++-++” refers to the current line plus 3.
  10. A percent sign “%” is equivalent to the address range “1,$”.

Ex commands require zero, one, or two addresses. It is an error to specify an address to a command which requires zero addresses.

If the user provides more than the expected number of addresses to any ex command, the first addresses specified are discarded. For example, “1,2,3,5”print prints lines 3 through 5, because the print command only takes two addresses.

The addresses in a range are separated from each other by a comma “,” or a semicolon “;”. In the latter case, the current line “.” is set to the first address, and only then is the second address calculated. This feature can be used to determine the starting line for forward and backward searches (see rules (5) and (6) above). The second address of any two-address sequence corresponds to a line that follows, in the file, the line corresponding to the first address. The first address must be less than or equal to the second address. The first address must be greater than or equal to the first line of the file, and the last address must be less than or equal to the last line of the file.

16 Ex Description

The following words have special meanings for ex commands.

  • <end-of-file>

    The end-of-file character is used to scroll the screen in the ex editor. This character is normally <control-D>. However, whatever character is set for the current terminal is supported as well as <control-D>.

  • line

    A single-line address, given in any of the forms described in the section entitled “Ex Addressing” . The default for lineis the current line.

  • range

    A line, or a pair of line addresses, separated by a comma or semicolon. (See the section entitled “Ex Addressing” for more information.) The default for range is the current line only, i.e. “.,.”. A percent sign “%” stands for the range “1,$”. The starting address must be less than, or equal to, the ending address.

  • count

    A positive integer, specifying the number of lines to be affected by the command; the default is 1. Generally, a count past the end-of-file may be specified, e.g. the command “p 3000” in a 10 line file is acceptable, and will print from the current line through the last line in the file.

  • flags

    One or more of the characters “#”, “p”, and “l”. When a command that accepts these flags completes, the addressed line(s) are written out as if by the corresponding #, l or p commands. In addition, any number of “+” or “-” characters can be specified before, after, or during the flags, in which case the line written is not necessarily the one affected by the command, but rather the line addressed by the offset address specified. The default for flagsis none.

  • file

    A pattern used to derive a pathname; the default is the current file. File names are subjected to normal sh(1) word expansions.

Anywhere a file name is specified, it is also possible to use the special string “/tmp”. This will be replaced with a temporary file name which can be used for temporary work, e.g. “:e /tmp” creates and edits a new file.

If both a count and a range are specified for commands that use either, the starting line for the command is the last line addressed by the range, and count- 1 subsequent lines are affected by the command, e.g. the command “2,3p4” prints out lines 3, 4, 5 and 6.

When only a line or range is specified, with no command, the implied command is either a list, number or print command. The command used is the most recent of the three commands to have been used (including any use as a flag). If none of these commands have been used before, the print command is the implied command. When no range or count is specified and the command line is a blank line, the current line is incremented by 1 and then the current line is displayed.

Zero or more whitespace characters may precede or follow the addresses, count, flags, or command name. Any object following a command name (such as buffer, file, etc.), that begins with an alphabetic character, should be separated from the command name by at least one whitespace character.

Any character, including <carriage-return>, “%” and “#” retain their literal value when preceded by a backslash.

17 Ex Commands

The following section describes the commands available in the ex editor. In each entry below, the tag line is a usage synopsis for the command.

Each command can be entered as the abbreviation (those characters in the synopsis command word preceding the “[” character), the full command (all characters shown for the command word, omitting the “[” and “]” characters), or any leading subset of the full command down to the abbreviation. For example, the args command (shown as “ar[gs]” in the synopsis) can be entered as “ar”, “arg” or “args”.

Each ex command described below notes the new current line after it is executed, as well as any options that affect the command.

— Command: "

A comment. Command lines beginning with the double-quote character “"” are ignored. This permits comments in editor scripts and startup files.

— Command: <control-D>
— Command: <end-of-file>

Scroll the screen. Write the next N lines, where N is the value of the scroll option. The command is the end-of-file terminal character, which may be different on different terminals. Traditionally, it is the <control-D>key.
Historically, the eof command ignored any preceding count, and the <end-of-file>character was ignored unless it was entered as the first character of the command. This implementation treats it as a command only if entered as the first character of the command line, and otherwise treats it as any other character.
Line:
Set to the last line written.
Options:
Affected by the scroll option.

— Command: ! argument(s)
— Command: [range]! argument(s)

Execute a shell command, or filter lines through a shell command. In the first synopsis, the remainder of the line after the “!” character is passed to the program named by the shell option, as a single argument.
Within the rest of the line, “%” and “#” are expanded into the current and alternate pathnames, respectively. The character “!” is expanded with the command text of the previous ! command. (Therefore, the command !! repeats the previous ! command.) The special meanings of “%”, “#”, and “!” can be overridden by escaping them with a backslash. If no ! or :! command has yet been executed, it is an error to use an unescaped “!” character. The ! command does not do shell expansion on the strings provided as arguments. If any of the above expansions change the command the user entered, the command is redisplayed at the bottom of the screen.
Ex then executes the program named by the shell option, with a -c flag followed by the arguments (which are bundled into a single argument).
The ! command is permitted in an empty file.
If the file has been modified since it was last completely written, the ! command will warn you.
A single “!” character is displayed when the command completes.
In the second form of the ! command, the remainder of the line after the “!” is passed to the program named by the shell option, as described above. The specified lines are passed to the program as standard input, and the standard and standard error output of the program replace the original lines.
Line:
Unchanged if no range was specified, otherwise set to the first line of the range.
Options:
Affected by the shell and warn options.

— Command: [range] # [

— Command: [range] nu[mber] [

Display the selected lines, each preceded with its line number.
The line number format is “%6d”, followed by two spaces.
Line:
Set to the last line displayed.
Options:
Affected by the list option.

— Command: @ buffer

— Command: * buffer

Execute a buffer. Each line in the named buffer is executed as an ex command. If no buffer is specified, or if the specified buffer is “@” or “*”, the last buffer executed is used.

— Command: [range] <[< ...] [

Shift lines left or right. The specified lines are shifted to the left (for the < command) or right (for the > command), by the number of columns specified by the shiftwidth option. Only leading whitespace characters are deleted when shifting left; once the first column of the line contains a nonblank character, the shift command will succeed, but the line will not be modified.
If the command character < or > is repeated more than once, the command is repeated once for each additional command character.
Line:
If the current line is set to one of the lines that are affected by the command, it is unchanged. Otherwise, it is set to the first nonblank character of the lowest numbered line shifted.
Options:
Affected by the shiftwidth option.

— Command: [line] = [

Display the line number of line(which defaults to the last line in the file).

Line:
Unchanged.
Options:
None.

— Command: [range] >[> ...] [

Shift right. The specified lines are shifted to the right by the number of columns specified by the shiftwidth option, by inserting tab and space characters. Empty lines are not changed.
If the command character “>” is repeated more than once, the command is repeated once for each additional command character.
Line:
Set to the last line modified by the command.
Options:
Affected by the shiftwidth option.

— Command: ab[brev] lhs rhs

Add an abbreviation to the current abbreviation list. When inserting text in vi, each time a non-word character is entered after a word character, a set of characters ending at the word character are checked for a match with lhs. If a match is found, they are replaced with rhs. The set of characters that are checked for a match are defined as follows, for inexplicable historical reasons. If only one or two characters were entered before the non-word character that triggered the check, and after the beginning of the insertion, or the beginning of the line or the file, or the last <blank>character that was entered, then the one or the both characters are checked for a match. Otherwise, the set includes both characters, as well as the characters that precede them that are the same word class (i.e. word or non-word) as the second to last character entered before the non-word character that triggered the check, back to the first <blank>character, the beginning of the insertion, or the beginning of the line or the file.
For example, the abbreviations:

:abbreviate abc ABC
:abbreviate #i #include
:abbreviate /*#i /*#include
will all work, while the abbreviations:

:abbreviate a#i A#include
:abbreviate /* /********************
will not work, and are not permitted by nvi.
To keep the abbreviation expansion from happening, the character immediately following the lhscharacters should be quoted with a <literal-next>character.
The replacement rhsis itself subject to both further abbreviation expansion and further map expansion.
Line:
Unchanged.
Options:
None.

— Command: [line] a[ppend][!]

The input text is appended to the specified line. If line 0 is specified, the text is inserted at the beginning of the file. Set to the last line input. If no lines are input, then set to line, or to the first line of the file if a lineof 0 was specified. Following the command name with a “!” character causes the autoindent option to be toggled for the duration of the command.

Line:
Unchanged.
Options:
Affected by the autoindent and number options.

— Command: ar[gs]

Display the argument list. The current argument is displayed inside of “[” and “]” characters. The argument list is the list of operands specified on startup, which can be replaced using the next command.

Line:
Unchanged.
Options:
None.

— Command: bg

Vi mode only. Background the current screen. The screen is unchanged, but is no longer accessible and disappears from the display. Use the fg command to bring the screen back to the display foreground.

Line:
Set to the current line when the screen was last edited.
Options:
None.

— Command: [range] c[hange][!] [

Replace the lines with input text. Following the command name with a “!” character causes the autoindent option to be toggled for the duration of the command.

Line:
Set to the last line input, or, if no lines were input, set to the line before the target line, or to the first line of the file if there are no lines preceding the target line.
Options:
Affected by the autoindent and number options.

— Command: chd[ir][!] [
— Command: cd[!] [

Change the current working directory. The directoryargument is subjected to sh(1) word expansions. When invoked with no directory argument and the HOMEenvironment variable is set, the directory named by the HOMEenvironment variable becomes the new current directory. Otherwise, the new current directory becomes the directory returned by the getpwent(3) routine.
The chdir command will fail if the file has been modified since the last complete write of the file. You can override this check by appending a “!” character to the command.
Line:
Unchanged.
Options:
Affected by the cdpath option.

— Command: [range] co[py] line [flags]
— Command: [range] t line [flags]

Copy the specified lines (range) after the destination line. Line 0 may be specified to insert the lines at the beginning of the file.

Line:
Unchanged.
Options:
None.

— Command: cs[cope] command [args]

Execute a cscope command. For more information, see the section of the reference manual entitled “Tags, Tag Stacks, and Cscope” .

— Command: [range] d[elete] [

Delete the lines from the file. The deleted text is saved in the specified buffer, or, if no buffer is specified, in the unnamed buffer. If the command name is followed by a letter that could be interpreted as either a buffer name or a flag value (because neither a countor flagsvalues were given), ex treats the letter as a flagsvalue if the letter immediately follows the command name, without any whitespace separation. If the letter is preceded by whitespace characters, it treats it as a buffer name.

Line:
Set to the line following the deleted lines, or to the last line if the deleted lines were at the end.
Options:
None.

— Command: di[splay] b[uffers] | c[onnections] | s[creens] | t[ags]

Display buffers, cscope connections, screens or tags. The display command takes one of three additional arguments, which are as follows:

b[uffers]
Display all buffers (including named, unnamed, and numeric) that contain text.
c[onnections]
Display the source directories for all attached cscope databases.
s[creens]
Display the file names of all background screens.
t[ags]
Display the tags stack.
Line:
Unchanged.
Options:
None.

— Command: e[dit][!] [
— Command: ex[!] [
— Command: vs[plit][!] [

Edit a different file. If the current buffer has been modified since the last complete write, the command will fail. You can override this by appending a “!” character to the command name.
If the “+cmd” option is specified, that ex command will be executed in the new file. Any ex command may be used, although the most common use of this feature is to specify a line number or search pattern to set the initial location in the new file.
Capitalizing the first letter of the command, i.e., Edit or Ex, while in vi mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored. vsplit is similar, but the screen will be split vertically to produce the new screen, rather than horizontally.
Line:
If you have previously edited the file, the current line will be set to your last position in the file. If that position does not exist, or you have not previously edited the file, the current line will be set to the first line of the file if you are in vi mode, and the last line of the file if you are in ex.
Options:
None.

— Command: exu[sage] [

Display usage for an ex command. If commandis specified, a usage statement for that command is displayed. Otherwise, usage statements for all ex commands are displayed.

Line:
Unchanged.
Options:
None.

— Command: f[ile] [

Display and optionally change the file name. If a file name is specified, the current pathname is changed to the specified name. The current pathname, the number of lines, and the current position in the file are displayed.

Line:
Unchanged.
Options:
None.

— Command: fg [

Vi mode only. Foreground the specified screen. If the argument name doesn't exactly match the name of a file displayed by a background screen, it is compared against the last component of each of the file names. If no background screen is specified, the first background screen is foregrounded.
By default, foregrounding causes the current screen to be swapped with the backgrounded screen. Capitalizing the first letter of the command, i.e. Fg, will foreground the backgrounded screen in a new screen instead of swapping it with the current screen.
Line:
Set to the current line when the screen was last edited.
Options:
None.

— Command: [range] g[lobal] /pattern/ [commands]

— Command: [range] v /pattern/ [commands]

Apply commands to lines matching (or not matching) a pattern. The lines within the given range that match “g[lobal]”, or do not match “v” the given pattern are selected. Then, the specified ex command(s) are executed with the current line “.” set to each selected line. If no range is specified, the entire file is searched for matching, or not matching, lines.
Multiple commands can be specified, one per line, by escaping each <newline>character with a backslash, or by separating commands with a “|” character. If no commands are specified, the command defaults to the print command.
For the append, change and insert commands, the input text must be part of the global command line. In this case, the terminating period can be omitted if it ends the commands.
The visual command may also be specified as one of the ex commands. In this mode, input is taken from the terminal. Entering a Q command in vi mode causes the next line matching the pattern to be selected and vi to be reentered, until the list is exhausted.
The global, v and undo commands cannot be used as part of these commands.
The editor options autoindent, autoprint and report are turned off for the duration of the global and v commands.
Line:
The last line modified.
Options:
Affected by the ignorecase and magic options. Turns off the autoindent, autoprint and report options.

— Command: he[lp]

Display a help message.

Line:
Unchanged.
Options:
None.

— Command: [line] i[nsert][!]

The input text is inserted before the specified line. Following the command name with a “!” character causes the autoindent option setting to be toggled for the duration of this command.

Line:
Set to the last line input; if no lines were input, set to the line before the target line, or to the first line of the file if there are no lines preceding the target line. Affected by the autoindent and number options.

— Command: [range] j[oin][!] [

Join lines of text together.
A countspecified to the join command specifies that the last line of the rangeplus countsubsequent lines will be joined. (Note, this differs by one from the general rule where only count- 1 subsequent lines are affected.)
If the current line ends with a whitespace character, all whitespace is stripped from the next line. Otherwise, if the next line starts with a open parenthesis “(”, do nothing. Otherwise, if the current line ends with a question mark “?”, period “.” or exclamation point “!”, insert two spaces. Otherwise, insert a single space.
Appending a “!” character to the command name causes a simpler join with no white-space processing.
Line:
Unchanged.
Options:
None.

— Command: [range] l[ist] [

Display the lines unambiguously. Tabs are displayed as “^I”, and the end of the line is marked with a “$” character.

Line:
Set to the last line displayed.
Options:
Affected by the number option.

— Command: map[!] [

Define or display maps (for vi only).
If “lhs” and “rhs” are not specified, the current set of command mode maps are displayed. If a “!” character is appended to to the command, the text input mode maps are displayed.
Otherwise, when the “lhs” character sequence is entered in vi, the action is as if the corresponding “rhs” had been entered. If a “!” character is appended to the command name, the mapping is effective during text input mode, otherwise, it is effective during command mode. This allows “lhs” to have two different macro definitions at the same time: one for command mode and one for input mode.
Whitespace characters require escaping with a <literal-next>character to be entered in the lhsstring in visual mode.
Normally, keys in the rhsstring are remapped (see the remap option), and it is possible to create infinite loops. However, keys which map to themselves are not further remapped, regardless of the setting of the remap option. For example, the command “:map n nz.” maps the “n” key to the n and z commands.
To exit an infinitely looping map, use the terminal <interrupt>character.
Line:
Unchanged.
Options:
Affected by the remap option.

— Command: [line] ma[rk] <character>
— Command: [line] k <character>

Mark the line with the mark <character>. The expressions “'<character>” and “`<character>” can then be used as an address in any command that uses one.

Line:
Unchanged.
Options:
None.

— Command: [range] m[ove] line

Move the specified lines after the target line. A target line of 0 places the lines at the beginning of the file.

Line:
Set to the first of the moved lines.
Options:
None.

— Command: mk[exrc][!] file

Write the abbreviations, editor options and maps to the specified file. Information is written in a form which can later be read back in using the ex source command. If filealready exists, the mkexrc command will fail. This check can be overridden by appending a “!” character to the command.

Line:
Unchanged.
Options:
None.

— Command: n[ext][!] [

Edit the next file from the argument list. The next command will fail if the file has been modified since the last complete write. This check can be overridden by appending the “!” character to the command name. The argument list can optionally be replaced by specifying a new one as arguments to this command. In this case, editing starts with the first file on the new list.
Capitalizing the first letter of the command, i.e. Next, while in vi mode, will set the argument list and edit the file in a new screen. In this case, any modifications to the current file are ignored.
Line:
Set as described for the edit command.
Options:
Affected by the options autowrite and writeany.

— Command: [line] o[pen] /pattern/ [flags]

Enter open mode. Open mode is the same as being in vi, but with a one-line window. All the standard vi commands are available. If a match is found for the optional RE argument, the cursor is set to the start of the matching pattern.
This command is not yet implemented.
Line:
Unchanged, unless the optional RE is specified, in which case it is set to the line where the matching pattern is found.
Options:
Affected by the open option.

— Command: pre[serve]

Save the file in a form that can later be recovered using the ex -r option. When the file is preserved, an email message is sent to the user.

Line:
Unchanged.
Options:
None.

— Command: prev[ious][!]

Edit the previous file from the argument list. The previous command will fail if the file has been modified since the last complete write. This check can be overridden by appending the “!” character to the command name.
Capitalizing the first letter of the command, i.e. Previous, while in vi mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored.
Line:
Set as described for the edit command.
Options:
Affected by the options autowrite and writeany. None.

— Command: [range] p[rint] [

Display the specified lines.

Line:
Set to the last line displayed.
Options:
Affected by the list and number option.

— Command: [line] pu[t] [

Append buffer contents to the current line. If a buffer is specified, its contents are appended to the line, otherwise, the contents of the unnamed buffer are used.

Line:
Set to the line after the current line.
Options:
None.

— Command: q[uit][!]

End the editing session. If the file has been modified since the last complete write, the quit command will fail. This check may be overridden by appending a “!” character to the command.
If there are more files to edit, the quit command will fail. Appending a “!” character to the command name or entering two quit commands (i.e. wq, quit, xit or ZZ) in a row) will override this check and the editor will exit.
Line:
Unchanged.
Options:
None.

— Command: [line] r[ead][!] [

Read a file. A copy of the specified file is appended to the line. If lineis 0, the copy is inserted at the beginning of the file. If no file is specified, the current file is read; if there is no current file, then filebecomes the current file. If there is no current file and no fileis specified, then the read command will fail.
If fileis preceded by a “!” character, fileis treated as if it were a shell command, and passed to the program named by the shell edit option. The standard and standard error outputs of that command are read into the file after the specified line. The special meaning of the “!” character can be overridden by escaping it with a backslash “e” character.
Line:
When executed from ex, the current line is set to the last line read. When executed from vi, the current line is set to the first line read.
Options:
None.

— Command: rec[over] file

Recover fileif it was previously saved. If no saved file by that name exists, the recover command behaves equivalently to the edit command.

Line:
Set as described for the edit command.
Options:
None.

— Command: res[ize] [

Vi mode only. Grow or shrink the current screen. If sizeis a positive, signed number, the current screen is grown by that many lines. If sizeis a negative, signed number, the current screen is shrunk by that many lines. If sizeis not signed, the current screen is set to the specified size. Applicable only to split screens.

Line:
Unchanged.
Options:
None.

— Command: rew[ind][!]

Rewind the argument list. If the current file has been modified since the last complete write, the rewind command will fail. This check may be overridden by appending the “!” character to the command.
Otherwise, the current file is set to the first file in the argument list.
Line:
Set as described for the edit command.
Options:
Affected by the autowrite and writeany options.

— Command: se[t] [

Display or set editor options. When no arguments are specified, the editor option term, and any editor options whose values have been changed from the default settings are displayed. If the argument allis specified, the values of all of editor options are displayed.
Specifying an option name followed by the character “?” causes the current value of that option to be displayed. The “?” can be separated from the option name by whitespace characters. The “?” is necessary only for Boolean valued options. Boolean options can be given values by the form “set option” to turn them on, or “set nooption” to turn them off. String and numeric options can be assigned by the form “set option=value”. Any whitespace characters in strings can be included literally by preceding each with a backslash. More than one option can be set or listed by a single set command, by specifying multiple arguments, each separated from the next by whitespace characters.
Line:
Unchanged.
Options:
None.

— Command: sh[ell]

Run the shell program. The program named by the shell option is run with a -i (for interactive) flag. Editing is resumed when that program exits.

Line:
Unchanged.
Options:
Affected by the shell option.

— Command: so[urce] file

Read and execute ex commands from a file. Source commands may be nested.

Line:
Unchanged.
Options:
None.

— Command: [range] s[ubstitute] [

— Command: [range] & [

— Command: [range] ~ [

Make substitutions. Replace the first instance of patternwith the string replaceon the specified line(s). If the “/pattern/repl/” argument is not specified, the “/pattern/repl/” from the previous substitute command is used. Any character other than an alphabetic, numeric, <blank> or backslash character may be used as the delimiter.
If optionsincludes the letter “c” (confirm), you will be prompted for confirmation before each replacement is done. An affirmative response (in English, a “y” character) causes the replacement to be made. A quit response (in English, a “q” character) causes the substitute command to be terminated. Any other response causes the replacement not to be made, and the substitute command continues. If optionsincludes the letter “g” (global), all nonoverlapping instances of patternin the line are replaced.
The & version of the command is the same as not specifying a pattern or replacement string to the substitute command, and the “&” is replaced by the pattern and replacement information from the previous substitute command.
The ~ version of the command is the same as & and s, except that the search pattern used is the last RE used in any command, not necessarily the one used in the last substitute command.
For example, in the sequence 
          s/red/blue/
          /green
          ~

the “~” is equivalent to “s/green/blue/”.
The substitute command may be interrupted, using the terminal interrupt character. All substitutions completed before the interrupt are retained.
Line:
Set to the last line upon which a substitution was made.
Options:
Affected by the ignorecase and magic option.

— Command: su[spend][!]

— Command: st[op][!]
— Comamnd: <control-Z>

Suspend the edit session. Appending a “!” character to these commands turns off the autowrite option for the command.

Line:
Unchanged.
Options:
Affected by the autowrite and writeany options.

— Command: ta[g][!] tagstring

Edit the file containing the specified tag. If the tag is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the tag command will fail. This check can be overridden by appending the “!” character to the command name.
The tag command searches for tagstringin the tags file(s) specified by the tags option. (See ctags(1) for more information on tags files.)
Capitalizing the first letter of the command, i.e. Tag, while in vi mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored.
Line:
Set to the line indicated by the tag.
Options:
Affected by the autowrite, taglength, tags and writeany options.

— Command: tagn[ext][!]

Edit the file containing the next context for the current tag. If the context is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the tagnext command will fail. This check can be overridden by appending the “!” character to the command name.
Capitalizing the first letter of the command, i.e. Tagnext, while in vi mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored.
Line:
Set to the line indicated by the tag.
Options:
Affected by the autowrite and writeany options.

— Command: tagp[op][!] [

Pop to the specified tag in the tags stack. If neither fileor numberis specified, the tagpop command pops to the most recent entry on the tags stack. If fileor numberis specified, the tagpop command pops to the most recent entry in the tags stack for that file, or numbered entry in the tags stack, respectively. (See the display command for information on displaying the tags stack.)
If the file has been modified since the last complete write, the tagpop command will fail. This check may be overridden by appending a “!” character to the command name.
Line:
Set to the line indicated by the tag.
Options:
Affected by the autowrite and writeany options.

— Command: tagp[rev][!]

Edit the file containing the previous context for the current tag. If the context is in a different file, then the new file is edited. If the current file has been modified since the last complete write, the tagprev command will fail. This check can be overridden by appending the “!” character to the command name.
Capitalizing the first letter of the command, i.e. Tagprev, while in vi mode, will edit the file in a new screen. In this case, any modifications to the current file are ignored.
Line:
Set to the line indicated by the tag.
Options:
Affected by the autowrite and writeany options.

— Command: tagt[op][!]

Pop to the least recent tag on the tags stack, clearing the tags stack.
If the file has been modified since the last complete write, the tagtop command will fail. This check may be overridden by appending a “!” character to the command name.
Line:
Set to the line indicated by the tag.
Options:
Affected by the autowrite and writeany options.

— Command: una[bbrev] lhs

Delete an abbreviation. Delete lhsfrom the current list of abbreviations.

Line:
Unchanged.
Options:
None.

— Command: u[ndo]

Undo the last change made to the file. Changes made by global, v, visual and map sequences are considered a single command. If repeated, the u command alternates between these two states, and is its own inverse.

Line:
Set to the last line modified by the command.
Options:
None.

— Command: unm[ap][!] lhs

Unmap a mapped string. Delete the command mode map definition for lhs. If a “!” character is appended to the command name, delete the text input mode map definition instead.

Line:
Unchanged.
Options:
None.

— Command: ve[rsion]

Display the version of the ex/vi editor.

— Command: [line] vi[sual] [

Ex mode only. Enter vi. The typeis optional, and can be “-”, “+” or “^”, as in the ex z command, to specify the position of the specified line in the screen window. (The default is to place the line at the top of the screen window.) A countspecifies the number of lines that will initially be displayed. (The default is the value of the window editor option.)

Line:
Unchanged unless lineis specified, in which case it is set to that line.
Options:
None.

— Command: vi[sual][!] [

Vi mode only. Edit a new file. Identical to the “edit[!] [+cmd] [file]” command.
Capitalizing the first letter of the command, i.e. Visual, will edit the file in a new screen. In this case, any modifications to the current file are ignored.

— Command: viu[sage] [

Display usage for a vi command. If commandis specified, a usage statement for that command is displayed. Otherwise, usage statements for all vi commands are displayed.

Line:
Unchanged.
Options:
None.

— Command: [range] w[rite][!] [
— Command: [range] w[rite] [

— Command: [range] wn[!] [

— Command: [range] wq[!] [

Write the file. The specified lines (the entire file, if no range is given) is written to file. If fileis not specified, the current pathname is used. If fileis specified, and it exists, or if the current pathname was set using the file command, and the file already exists, these commands will fail. Appending a “!” character to the command name will override this check and the write will be attempted, regardless.
Specifying the optional “>>” string will cause the write to be appended to the file, in which case no tests are made for the file already existing.
If the file is preceded by a “!” character, the program named by the shell edit option is invoked with file as its second argument, and the specified lines are passed as standard input to that command. The “!” in this usage must be separated from command name by at least one whitespace character. The special meaning of the “!” may be overridden by escaping it with a backslash “e” character.
The wq version of the write command will exit the editor after writing the file, if there are no further files to edit. Appending a “!” character to the command name or entering two “quit” commands (i.e. wq, quit, xit or ZZ) in a row) will override this check and the editor will exit, ignoring any files that have not yet been edited.
The wn version of the write command will move to the next file after writing the file, unless the write fails.
Line:
Unchanged.
Options:
Affected by the readonly and writeany options.

— Command: [range] x[it][!] [

Write the file if it has been modified. The specified lines are written to file, if the file has been modified since the last complete write to any file. If no rangeis specified, the entire file is written.
The xit command will exit the editor after writing the file, if there are no further files to edit. Appending a “!” character to the command name or entering two “quit” commands (i.e. wq, quit, xit or ZZ) in a row) will override this check and the editor will exit, ignoring any files that have not yet been edited.
Line:
Unchanged.
Options:
Affected by the readonly and writeany options.

— Command: [range] ya[nk] [

Copy the specified lines to a buffer. If no buffer is specified, the unnamed buffer is used.

Line:
Unchanged.
Options:
None.

— Command: [line] z [

Adjust the window. If no typeis specified, then countlines following the specified line are displayed. The default countis the value of the window option. The typeargument changes the position at which lineis displayed on the screen by changing the number of lines displayed before and after line. The following typecharacters may be used:

-
Place the line at the bottom of the screen.
+
Place the line at the top of the screen.
.
Place the line in the middle of the screen.
^
Write out count lines starting count * 2lines before line; the net effect of this is that a “z^” command following a z command writes the previous page.
=
Center lineon the screen with a line of hyphens displayed immediately before and after it. The number of preceding and following lines of text displayed are reduced to account for those lines.
Line:
Set to the last line displayed, with the exception of the “=” type, where the current line is set to the line specified by the command.
Options:
Affected by the scroll option.

18 Set Options

There are a large number of options that may be set (or unset) to change the editor's behavior. This section describes the options, their abbreviations and their default values.

In each entry below, the first part of the tag line is the full name of the option, followed by any equivalent abbreviations. (Regardless of the abbreviations, it is only necessary to use the minimum number of characters necessary to distinguish an abbreviation from all other commands for it to be accepted, in nex/nvi. Historically, only the full name and the official abbreviations were accepted by ex/vi. Using full names in your startup files and environmental variables will probably make them more portable.) The part in square brackets is the default value of the option. Most of the options are boolean, i.e. they are either on or off, and do not have an associated value.

Options apply to both ex and vi modes, unless otherwise specified.

With a few exceptions, all options are settable per screen, i.e. the tags option can be set differently in each screen. The exceptions are the columns, lines, secure and term options. Changing these options modifies the respective information for all screens.

For information on modifying the options or to display the options and their current values, see the “set” command in the section entitled “Ex Commands” .

  • altwerase [off]

    Vi only. Change how vi does word erase during text input. When this option is set, text is broken up into three classes: alphabetic, numeric and underscore characters, other nonblank characters, and blank characters. Changing from one class to another marks the end of a word. In addition, the class of the first character erased is ignored (which is exactly what you want when erasing pathname components).

  • autoindent, ai [off]

    If this option is set, whenever you create a new line (using the vi A, a, C, c, I, i, O, o, R, r, S, and s commands, or the ex append, change, and insert commands) the new line is automatically indented to align the cursor with the first nonblank character of the line from which you created it. Lines are indented using tab characters to the extent possible (based on the value of the tabstop option) and then using space characters as necessary. For commands inserting text into the middle of a line, any blank characters to the right of the cursor are discarded, and the first nonblank character to the right of the cursor is aligned as described above.
    The indent characters are themselves somewhat special. If you do not enter more characters on the new line before moving to another line, or entering <escape>, the indent character will be deleted and the line will be empty. For example, if you enter <carriage-return>twice in succession, the line created by the first <carriage-return>will not have any characters in it, regardless of the indentation of the previous or subsequent line.
    Indent characters also require that you enter additional erase characters to delete them. For example, if you have an indented line, containing only blanks, the first <word-erase>character you enter will erase up to end of the indent characters, and the second will erase back to the beginning of the line. (Historically, only the <control-D>key would erase the indent characters. Both the <control-D>key and the usual erase keys work in nvi.) In addition, if the cursor is positioned at the end of the indent characters, the keys “0<control-D>” will erase all of the indent characters for the current line, resetting the indentation level to 0. Similarly, the keys “^<control-D>” will erase all of the indent characters for the current line, leaving the indentation level for future created lines unaffected.
    Finally, if the autoindent option is set, the S and cc commands change from the first nonblank of the line to the end of the line, instead of from the beginning of the line to the end of the line.
  • autoprint, ap [off]

    Ex only. Cause the current line to be automatically displayed after the ex commands <, >, copy, delete, join, move, put, t, Undo, and undo. This automatic display is suppressed during global and v commands, and for any command where optional flags are used to explicitly display the line.

  • autowrite, aw [off]

    If this option is set, the vi !, ^^, ^] and <control-Z> commands, and the ex edit, next, rewind, stop, suspend, tag, tagpop, and tagtop commands automatically write the current file back to the current file name if it has been modified since it was last written. If the write fails, the command fails and goes no further.
    Appending the optional force flag character “!” to the ex commands next, rewind, stop, suspend, tag, tagpop, and tagtop stops the automatic write from being attempted.
    (Historically, the next command ignored the optional force flag.) Note, the ex commands edit, quit, shell, and xit are not affected by the autowrite option.
    The autowrite option is ignored if the file is considered read-only for any reason.
  • backup [""]

    If this option is set, it specifies a pathname used as a backup file, and, whenever a file is written, the file's current contents are copied to it. The pathname is “#”, “%” and “!” expanded.
    If the first character of the pathname is “N”, a version number is appended to the pathname (and the “N” character is then discarded). Version numbers are always incremented, and each backup file will have a version number one greater than the highest version number currently found in the directory.
    Backup files must be regular files, owned by the real user ID of the user running the editor, and not accessible by any other user.
  • beautify, bf [off]

    If this option is set, all control characters that are not currently being specially interpreted, other than <tab>, <newline>, and <form-feed>, are discarded from commands read in by ex from command files, and from input text entered to vi (either into the file or to the colon command line). Text files read by ex/vi are not affected by the beautify option.

  • cdpath [environment variable CDPATH, or current directory]

    This option is used to specify a colon separated list of directories which are used as path prefixes for any relative path names used as arguments for the cd command. The value of this option defaults to the value of the environmental variable CDPATHif it is set, otherwise to the current directory. For compatibility with the POSIX 1003.2 shell, the cd command does not check the current directory as a path prefix for relative path names unless it is explicitly specified. It may be so specified by entering an empty string or a “.” character into the CDPATHvariable or the option value.

  • cedit [no default]

    This option adds the ability to edit the colon command-line history. This option is set to a string. Whenever the first character of that string is entered on the colon command line, you will enter a normal editing window on the collected commands that you've entered on the vi colon command-line. You may then modify and/or execute the commands. All normal text editing is available, except that you cannot use <control-W> to switch to an alternate screen. Entering a <carriage-return> will execute the current line of the screen window as an ex command in the context of the screen from which you created the colon command-line screen, and you will then return to that screen.
    Because of vi's parsing rules, it can be difficult to set the colon command-line edit character to the <escape>character. To set it to <escape>, use “set cedit=<literal-next><escape>”.
    If the cedit edit option is set to the same character as the filec edit option, vi will perform colon command-line editing if the character is entered as the first character of the line, otherwise, vi will perform file name expansion.
  • columns, co [80]

    The number of columns in the screen. Setting this option causes ex/vi to set (or reset) the environmental variable COLUMNS. See the section entitled “Sizing the Screen” more information.

  • comment [off]

    Vi only. If the first non-empty line of the file begins with the string “#”, “/*” or “//”, this option causes vi to skip to the end of that shell, C or C++ comment (probably a terribly boring legal notice) before displaying the file.

  • directory, dir [environment variable TMPDIR, or /tmp]

    The directory where temporary files are created. The environmental variable TMPDIRis used as the default value if it exists, otherwise /tmpis used.

  • edcompatible, ed [off]

    Remember the values of the “c” and “g” suffixes to the substitute commands, instead of initializing them as unset for each new command. Specifying pattern and replacement strings to the substitute command unsets the “c” and “g” suffixes as well.

  • escapetime [1]

    The 10th's of a second ex/vi waits for a subsequent key to complete an <escape>key mapping.

  • errorbells, eb [off]

    Ex only. Ex error messages are normally presented in inverse video. If that is not possible for the terminal, setting this option causes error messages to be announced by ringing the terminal bell.

  • exrc, ex [off]

    If this option is turned on in the EXINIT environment variables, or the system or $HOME startup files, the local startup files are read, unless they are the same as the system or $HOME startup files or fail to pass the standard permission checks. See the section entitled “Startup Information” for more information.

  • extended [off]

    This option causes all regular expressions to be treated as POSIX 1003.2 Extended Regular Expressions (which are similar to historic egrep(1) style expressions).

  • filec [no default]

    This option adds the ability to do shell expansion when entering input on the colon command line. This option is set to a string. Whenever the first character of that string is entered on the colon command line, the <blank> delimited string immediately before the cursor is expanded as if it were followed by a *character, and file name expansion for the ex edit command was done. If no match is found, the screen is flashed and text input resumed. If a single match results, that match replaces the expanded text. In addition, if the single match is for a directory, a /character is appended and file completion is repeated. If more than a single match results, any unique prefix shared by the matches replaces the expanded text, the matches are displayed, and text input resumed.
    Because of vi's parsing rules, it can be difficult to set the path completion character to two command values, <escape>and <tab>. To set it to <escape>, use “set filec=<literal-next><escape>”. To set it to <tab>, use “set filec=e<tab>”.
    If the cedit edit option is set to the same character as the filec edit option, vi will perform colon command-line editing if the character is entered as the first character of the line, otherwise, vi will perform file name expansion.
  • flash [on]

    This option causes the screen to flash instead of beeping the keyboard, on error, if the terminal has the capability.

  • hardtabs, ht [8]

    This option defines the spacing between hardware tab settings, i.e. the tab expansion done by the operating system and/or the terminal itself. As nex/nvi never writes <tab>characters to the terminal, unlike historic versions of ex/vi, this option does not currently have any affect.

  • iclower [off]

    The iclower edit option makes all Regular Expressions case-insensitive, as long as an upper-case letter does not appear in the search string.

  • ignorecase, ic [off]

    This option causes regular expressions, both in ex commands and in searches, to be evaluated in a case-insensitive manner.

  • keytime [6]

    The 10th's of a second ex/vi waits for a subsequent key to complete a key mapping.

  • leftright [off]

    Vi only. This option causes the screen to be scrolled left-right to view lines longer than the screen, instead of the traditional vi screen interface which folds long lines at the right-hand margin of the terminal.

  • lines, li [24]

    Vi only. The number of lines in the screen. Setting this option causes ex/vi to set (or reset) the environmental variable LINES. See the section entitled “Sizing the Screen” for more information.

  • lisp [off]

    Vi only. This option changes the behavior of the vi (, ), {, }, [[ and ]] commands to match the Lisp language. Also, the autoindent option's behavior is changed to be appropriate for Lisp.
    This option is not yet implemented.
  • list [off]

    This option causes lines to be displayed in an unambiguous fashion. Specifically, tabs are displayed as control characters, i.e. “^I”, and the ends of lines are marked with a “$” character.

  • lock [on]

    This option causes the editor to attempt to get an exclusive lock on any file being edited, read or written. Reading or writing a file that cannot be locked produces a warning message, but no other effect. Editing a file that cannot be locked results in a read only edit session, as if the readonly edit option were set.

  • magic [on]

    This option is on by default. Turning the magic option off causes all regular expression characters except for “^” and “$”, to be treated as ordinary characters. To re-enable characters individually, when the magic option is off, precede them with a backslash “e” character. See the section entitled “Regular Expressions and Replacement Strings” for more information.

  • matchtime [7]

    Vi only. The 10th's of a second vi pauses on the matching character when the showmatch option is set.

  • mesg [on]

    This option allows other users to contact you using the talk(1) and write(1) utilities, while you are editing. Ex/vi does not turn message on, i.e. if messages were turned off when the editor was invoked, they will stay turned off. This option only permits you to disallow messages for the edit session. See the mesg(1) utility for more information.

  • msgcat [./]

    This option selects a message catalog to be used to display error and informational messages in a specified language. If the value of this option ends with a '/', it is treated as the name of a directory that contains a message catalog “vi_XXXX”, where “XXXX” is the value of the LANGenvironmental variable, if it's set, or the value of the LC_MESSAGESenvironmental variable if it's not. If neither of those environmental variables are set, or if the option doesn't end in a '/', the option is treated as the full path name of the message catalog to use.
    If any messages are missing from the catalog, the backup text (English) is used instead.
    See the distribution file catalog/READMEfor additional information on building and installing message catalogs.
  • modelines, modeline [off]

    If the modelines option is set, ex/vi has historically scanned the first and last five lines of each file as it is read for editing, looking for any ex commands that have been placed in those lines. After the startup information has been processed, and before the user starts editing the file, any commands embedded in the file are executed.
    Commands were recognized by the letters “e” or “v” followed by “x” or “i”, at the beginning of a line or following a tab or space character, and followed by a “:”, an ex command, and another “:”.
    This option is a security problem of immense proportions, and should not be used under any circumstances.
    This option will never be implemented.
  • noprint [""]

    Characters that are never handled as printable characters. By default, the C library function isprint(3) is used to determine if a character is printable or not. This edit option overrides that decision.

  • number, nu [off]

    Precede each line displayed with its current line number.

  • octal [off]

    Display unknown characters as octal numbers “"e###"”, instead of the default hexadecimal “"ex##"”.

  • open [on]

    Ex only. If this option is not set, the open and visual commands are disallowed.

  • optimize, opt [on]

    Vi only. Throughput of text is expedited by setting the terminal not to do automatic carriage returns when printing more than one (logical) line of output, greatly speeding output on terminals without addressable cursors when text with leading white space is printed.
    This option is not yet implemented.
  • paragraphs, para [IPLPPPQPP LIpplpipbp]

    Vi only. Define additional paragraph boundaries for the { and } commands. The value of this option must be a character string consisting of zero or more character pairs.
    In the text to be edited, the character string <newline>.<char-pair>, (where <char-pair>is one of the character pairs in the option's value) defines a paragraph boundary. For example, if the option were set to LaA<space>##, then all of the following additional paragraph boundaries would be recognized: 
         
     
              <newline>.La
          <newline>.A<space>
          <newline>.##

  • path []

    The path option can be used to specify a <colon>-separated list of paths, similar to the PATHenvironment variable in the shells. If this option is set, the name of the file to be edited is not an absolute pathname, the first component of the filename is not “.” or “..”, and the file to be edited doesn't exist in the current directory, the elements of the path option are sequentially searched for a file of the specified name. If such a file is found, it is edited.

  • print [""]

    Characters that are always handled as printable characters. By default, the C library function isprint(3) is used to determine if a character is printable or not. This edit option overrides that decision.

  • prompt [on]

    Ex only. This option causes ex to prompt for command input with a “:” character; when it is not set, no prompt is displayed.

  • readonly, ro [off]

    This option causes a force flag to be required to attempt to write the file. Setting this option is equivalent to using the -R command line option, or executing the vi program using the name view.
    The readonly edit option is not usually persistent, like other edit options. If the -R command line option is set, vi is executed as view, or the readonly edit option is explicitly set, all files edited in the screen will be marked readonly, and the force flag will be required to write them. However, if none of these conditions are true, or the readonly edit option is explicitly unset, then the readonly edit option will toggle based on the write permissions of the file currently being edited as of when it is loaded into the edit buffer. In other words, the readonly edit option will be set if the current file lacks write permissions, and will not be set if the user has write permissions for the file.
  • recdir [/var/tmp/vi.recover]

    The directory where recovery files are stored.
    If you change the value of recdir, be careful to choose a directory whose contents are not regularly deleted. Bad choices include directories in memory based filesystems, or /tmp, on most systems, as their contents are removed when the machine is rebooted.
    Public directories like /usr/tmpand /var/tmpare usually safe, although some sites periodically prune old files from them. There is no requirement that you use a public directory, e.g. a sub-directory of your home directory will work fine.
    Finally, if you change the value of recdir, you must modify the recovery script to operate in your chosen recovery area.
    See the section entitled “Recovery” for further information.
  • redraw, re [off]

    Vi only. The editor simulates (using great amounts of output), an intelligent terminal on a dumb terminal (e.g. during insertions in vi the characters to the right of the cursor are refreshed as each input character is typed).
    This option is not yet implemented.
  • remap [on]

    If this option is set, it is possible to define macros in terms of other macros. Otherwise, each key is only remapped up to one time. For example, if “A” is mapped to “B”, and “B” is mapped to “C”, The keystroke “A” will be mapped to “C” if the remap option is set, and to “B” if it is not set.

  • report [5]

    Set the threshold of the number of lines that need to be changed or yanked before a message will be displayed to the user. For everything but the yank command, the value is the largest value about which the editor is silent, i.e. by default, 6 lines must be deleted before the user is notified. However, if the number of lines yanked is greater than or equal to the set value, it is reported to the user.

  • ruler [off]

    Vi only. Display a row/column ruler on the colon command line.

  • scroll, scr [(environment variable LINES - 1) / 2]

    Set the number of lines scrolled by the ex <control-D> and <end-of-file> commands.
    Historically, the ex z command, when specified without a count, used two times the size of the scroll value; the POSIX 1003.2 standard specified the window size, which is a better choice.
  • searchincr [off]

    The searchincr edit option makes the search commands / and ? incremental, i.e. the screen is updated and the cursor moves to the matching text as the search pattern is entered. If the search pattern is not found, the screen is beeped and the cursor remains on the colon-command line. Erasing characters from the search pattern backs the cursor up to the previous matching text.

  • sections, sect [NHSHH HUnhsh]

    Vi only. Define additional section boundaries for the [[ and ]] commands. The sections option should be set to a character string consisting of zero or more character pairs. In the text to be edited, the character string <newline>.<char-pair>, (where <char-pair>is one of the character pairs in the option's value), defines a section boundary in the same manner that paragraphs option boundaries are defined.

  • secure [off]

    The secure edit option turns off all access to external programs. This means that the versions of the read and write commands that filter text through other programs, the vi ! and <control-Z> commands, the ex !, script, shell, stop and suspend commands and file name expansion will not be permitted. Once set, the secure edit option may not be unset.

  • shell, sh [environment variable SHELL, or /bin/sh]

    Select the shell used by the editor. The specified path is the pathname of the shell invoked by the vi ! shell escape command and by the ex shell command. This program is also used to resolve any shell meta-characters in ex commands.

  • shellmeta [~{[*?$`'"\]

    The set of characters that ex checks for when doing file name expansion. If any of the specified characters are found in the file name arguments to the ex commands, the arguments are expanded using the program defined by the shell option. The default set of characters is a union of meta characters from the Version 7 and the Berkeley C shell.

  • shiftwidth, sw [8]

    Set the autoindent and shift command indentation width. This width is used by the autoindent option and by the <, >, and shift commands.

  • showmatch, sm [off]

    Vi only. This option causes vi, when a “}” or “)” is entered, to briefly move the cursor the matching “{” or “(”. See the matchtime option for more information.

  • showmode, smd [off]

    Vi only. This option causes vi to display a string identifying the current editor mode on the colon command line. The string is preceded by an asterisk (“*”) if the file has been modified since it was last completely written,

  • sidescroll [16]

    Vi only. Sets the number of columns that are shifted to the left or right, when vi is doing left-right scrolling and the left or right margin is crossed. See the leftright option for more information.

  • slowopen, slow [off]

    This option affects the display algorithm used by vi, holding off display updating during input of new text to improve throughput when the terminal in use is slow and unintelligent.
    This option is not yet implemented.
  • sourceany [off]

    If this option is turned on, vi historically read startup files that were owned by someone other than the editor user. See the section entitled “Startup Information” for more information. This option is a security problem of immense proportions, and should not be used under any circumstances.
    This option will never be implemented.
  • tabstop, ts [8]

    This option sets tab widths for the editor display.

  • taglength, tl [0]

    This option sets the maximum number of characters that are considered significant in a tag name. Setting the value to 0 makes all of the characters in the tag name significant.

  • tags, tag [tags /var/db/libc.tags /sys/kern/tags]

    Sets the list of tags files, in search order, which are used when the editor searches for a tag.

  • term, ttytype, tty [environment variable TERM]

    Set the terminal type. Setting this option causes ex/vi to set (or reset) the environmental variable TERM.

  • terse [off]

    This option has historically made editor messages less verbose. It has no effect in this implementation. See the verbose option for more information.

  • tildeop [off]

    Modify the ~ command to take an associated motion.

  • timeout, to [on]

    If this option is set, ex/vi waits for a specific period for a subsequent key to complete a key mapping (see the keytime option). If the option is not set, the editor waits until enough keys are entered to resolve the ambiguity, regardless of how long it takes.

  • ttywerase [off]

    Vi only. This option changes how vi does word erase during text input. If this option is set, text is broken up into two classes, blank characters and nonblank characters. Changing from one class to another marks the end of a word.

  • verbose [off]

    Vi only. Vi historically bells the terminal for many obvious mistakes, e.g. trying to move past the left-hand margin, or past the end of the file. If this option is set, an error message is displayed for all errors.

  • w300 [no default]

    Vi only. Set the window size if the baud rate is less than 1200 baud. See the window option for more information.

  • w1200 [no default]

    Vi only. Set the window size if the baud rate is equal to 1200 baud. See the window option for more information.

  • w9600 [no default]

    Vi only. Set the window size if the baud rate is greater than 1200 baud. See the window option for more information.

  • warn [on]

    Ex only. This option causes a warning message to the terminal if the file has been modified, since it was last written, before a ! command.

  • window, w, wi [environment variable LINES - 1]

    This option determines the default number of lines in a screenful, as displayed by the z command. It also determines the number of lines scrolled by the vi commands <control-B> and <control-F>, and the default number of lines scrolled by the vi commands <control-D> and <control-U>. The value of window can be unrelated to the real screen size, although it starts out as the number of lines on the screen. See the section entitled “Sizing the Screen” for more information. Setting the value of the window option is the same as using the -w command line option.
    If the value of the window option (as set by the window, w300, w1200 or w9600 options) is smaller than the actual size of the screen, large screen movements will result in displaying only that smaller number of lines on the screen. (Further movements in that same area will result in the screen being filled.) This can provide a performance improvement when viewing different places in one or more files over a slow link.
    Resetting the window size does not reset the default number of lines scrolled by the <control-D> and <control-U> commands.
  • windowname [off]

    Vi changes the name of the editor's icon/window to the current file name when it's possible and not destructive, i.e., when the editor can restore it to its original value on exit or when the icon/window will be discarded as the editor exits. If the windowname edit option is set, vi will change the icon/window name even when it's destructive and the icon/window name will remain after the editor exits. (This is the case for xterm(1)).

  • wraplen, wl [0]

    This option is identical to the wrapmargin option, with the exception that it specifies the number of columns from the left margin before the line splits, not the right margin.
    If both wraplen and wrapmargin are set, the wrapmargin value is used.
  • wrapmargin, wm [0]

    Vi only. If the value of the wrapmargin option is non-zero, vi will split lines so that they end at least that number of columns before the right-hand margin of the screen. (Note, the value of wrapmargin is not a text length. In a screen that is 80 columns wide, the command “:set wrapmargin=8” attempts to keep the lines less than or equal to 72 columns wide.)
    Lines are split at the previous whitespace character closest to the number. Any trailing whitespace characters before that character are deleted. If the line is split because of an inserted <space>or <tab>character, and you then enter another <space>character, it is discarded.
    If wrapmargin is set to 0, or if there is no blank character upon which to split the line, the line is not broken.
    If both wraplen and wrapmargin are set, the wrapmargin value is used.
  • wrapscan, ws [on]

    This option causes searches to wrap around the end or the beginning of the file, and back to the starting point. Otherwise, the end or beginning of the file terminates the search.

  • writeany, wa [off]

    If this option is set, file-overwriting checks that would usually be made before the write and xit commands, or before an automatic write (see the autowrite option), are not made. This allows a write to any file, provided the file permissions allow it.

Vi (visual) is a display oriented interactive
text editor. When using vi the screen of your
terminal acts as a window into the file which you are
editing. Changes which you make to the file are reflected in
what you see.



Using vi you can insert new text any place in the
file quite easily. Most of the commands to vi move
the cursor around in the file. There are commands to move
the cursor forward and backward in units of characters,
words, sentences and paragraphs. A small set of operators,
like d for delete and c for change, are
combined with the motion commands to form operations such as
delete word or change paragraph, in a simple and natural
way. This regularity and the mnemonic assignment of commands
to keys makes the editor command set easy to remember and to
use.



Vi will work on a large number of display
terminals, and new terminals are easily driven after editing
a terminal description file. While it is advantageous to
have an intelligent terminal which can locally insert and
delete lines and characters from the display, the editor
will function quite well on dumb terminals over slow phone
lines. The editor makes allowance for the low bandwidth in
these situations and uses smaller window sizes and different
display updating algorithms to make best use of the limited
speed available.



It is also possible to use the command set of vi
on hardcopy terminals, storage tubes and ``glass tty's''
using a one line editing window; thus vi's command
set is available on all terminals. The full command set of
the more traditional, line oriented editor ex is
available within vi; it is quite simple to switch
between the two modes of editing.



1. Getting started






This document provides a quick introduction to
vi. (Pronounced vee-eye.) You should be
running vi on a file you are familiar with while you
are reading this. The first part of this document (sections
1 through 5) describes the basics of using vi. Some
topics of special interest are presented in section 6, and
some nitty-gritty details of how the editor functions are
saved for section 7 to avoid cluttering the presentation
here.



There is also a short appendix here, which gives for
each character the special meanings which this character has
in vi. Attached to this document should be a quick
reference card. This card summarizes the commands of
vi in a very compact format. You should have the card
handy while you are learning vi.



1.1. Specifying terminal type



Before you can start vi you must tell the system
what kind of terminal you are using. Here is a (necessarily
incomplete) list of terminal type codes. If your terminal
does not appear here, you should consult with one of the
staff members on your system to find out the code for your
terminal. If your terminal does not have a code, one can be
assigned and a description for the terminal can be
created.






Suppose for example that you have a Hewlett-Packard
HP2621A terminal. The code used by the system for this
terminal is `2621'. In this case you can use one of the
following commands to tell the system the type of your
terminal:


     % setenv TERM 2621




This command works with the csh shell. If you are
using the standard Bourne shell sh then you should
give the commands


     $ TERM=2621
     $ export TERM




If you want to arrange to have your terminal type set up
automatically when you log in, you can use the tset
program. If you dial in on a mime, but often use
hardwired ports, a typical line for your .login file
(if you use csh) would be


     setenv TERM tset - -d mime




or for your .profile file (if you use sh)


     TERM=tset - -d mime




Tset knows which terminals are hardwired to each
port and needs only to be told that when you dial in you are
probably on a mime. Tset is usually used to
change the erase and kill characters, too.



1.2. Editing a file



After telling the system which kind of terminal you
have, you should make a copy of a file you are familiar
with, and run vi on this file, giving the command


     % vi name




replacing name with the name of the copy file you
just created. The screen should clear and the text of your
file should appear on the screen. If something else happens
refer to the footnote.






1.3. The editor's copy: the buffer



The editor does not directly modify the file which you
are editing. Rather, the editor makes a copy of this file,
in a place called the buffer, and remembers the
file's name. You do not affect the contents of the file
unless and until you write the changes you make back into
the original file.



1.4. Notational conventions



In our examples, input which must be typed as is will be
presented in bold face. Text which should be replaced
with appropriate input will be given in italics. We
will represent special characters in SMALL
CAPITALS .



1.5. Arrow keys



The editor command set is independent of the terminal
you are using. On most terminals with cursor positioning
keys, these keys will also work within the editor. If you
don't have cursor positioning keys, or even if you do, you
can use the h j k and l keys as cursor
positioning keys (these are labelled with arrows on an
adm3a).*



(Particular note for the HP2621: on this terminal the
function keys must be shifted (ick) to send to the
machine, otherwise they only act locally. Unshifted use will
leave the cursor positioned incorrectly.)






1.6. Special characters: ESC , CR and DEL



Several of these special characters are very important,
so be sure to find them right now. Look on your keyboard for
a key labelled ESC or ALT . It
should be near the upper left corner of your terminal. Try
hitting this key a few times. The editor will ring the bell
to indicate that it is in a quiescent state.






Partially formed commands are cancelled by
ESC , and when you insert text in the file
you end the text insertion with ESC . This
key is a fairly harmless one to hit, so you can just hit it
if you don't know what is going on until the editor rings
the bell.



The CR or RETURN key is
important because it is used to terminate certain commands.
It is usually at the right side of the keyboard, and is the
same command used at the end of each shell command.



Another very useful key is the DEL or
RUB key, which generates an interrupt,
telling the editor to stop what it is doing. It is a
forceful way of making the editor listen to you, or to
return it to the quiescent state if you don't know or don't
like what is going on. Try hitting the `/' key on your
terminal. This key is used when you want to specify a string
to be searched for. The cursor should now be positioned at
the bottom line of the terminal after a `/' printed as a
prompt. You can get the cursor back to the current position
by hitting the DEL or RUB key;
try this now.*






From now on we will simply refer to hitting the
DEL or RUB key as ``sending an
interrupt.''**






The editor often echoes your commands on the last line
of the terminal. If the cursor is on the first position of
this last line, then the editor is performing a computation,
such as computing a new position in the file after a search
or running a command to reformat part of the buffer. When
this is happening you can stop the editor by sending an
interrupt.



1.7. Getting out of the editor



After you have worked with this introduction for a
while, and you wish to do something else, you can give the
command ZZ to the editor. This will write the
contents of the editor's buffer back into the file you are
editing, if you made any changes, and then quit from the
editor. You can also end an editor session by giving the
command :q! CR ;






this is a dangerous but occasionally essential command
which ends the editor session and discards all your changes.
You need to know about this command in case you change the
editor's copy of a file you wish only to look at. Be very
careful not to give this command when you really want to
save the changes you have made.



2. Moving around in the file



2.1. Scrolling and paging



The editor has a number of commands for moving around in
the file. The most useful of these is generated by hitting
the control and D keys at the same time, a control-D or
`^D'. We will use this two character notation for referring
to these control keys from now on. You may have a key
labelled `^' on your terminal. This key will be represented
as `' in this document; `^' is exclusively used as part of
the `^x' notation for control characters.






As you know now if you tried hitting ^D, this
command scrolls down in the file. The D thus stands
for down. Many editor commands are mnemonic and this makes
them much easier to remember. For instance the command to
scroll up is ^U. Many dumb terminals can't scroll up
at all, in which case hitting ^U clears the screen
and refreshes it with a line which is farther back in the
file at the top.



If you want to see more of the file below where you are,
you can hit ^E to expose one more line at the bottom
of the screen, leaving the cursor where it is. The command
^Y (which is hopelessly non-mnemonic, but next to
^U on the keyboard) exposes one more line at the top
of the screen.



There are other ways to move around in the file; the
keys ^F and ^B move forward and backward a
page, keeping a couple of lines of continuity between
screens so that it is possible to read through a file using
these rather than ^D and ^U if you wish.



Notice the difference between scrolling and paging. If
you are trying to read the text in a file, hitting ^F
to move forward a page will leave you only a little context
to look back at. Scrolling on the other hand leaves more
context, and happens more smoothly. You can continue to read
the text as scrolling is taking place.



2.2. Searching, goto, and previous context



Another way to position yourself in the file is by
giving the editor a string to search for. Type the character
/ followed by a string of characters terminated by
CR . The editor will position the cursor at
the next occurrence of this string. Try hitting n to
then go to the next occurrence of this string. The character
? will search backwards from where you are, and is
otherwise like /.






If the search string you give the editor is not present
in the file the editor will print a diagnostic on the last
line of the screen, and the cursor will be returned to its
initial position.



If you wish the search to match only at the beginning of
a line, begin the search string with an . To match only at
the end of a line, end the search string with a $.
Thus /search CR will search for the
word `search' at the beginning of a line, and /last$
CR searches for the word `last' at the end of
a line.*






The command G, when preceded by a number will
position the cursor at that line in the file. Thus 1G
will move the cursor to the first line of the file. If you
give G no count, then it moves to the end of the
file.



If you are near the end of the file, and the last line
is not at the bottom of the screen, the editor will place
only the character `~' on each remaining line. This
indicates that the last line in the file is on the screen;
that is, the `~' lines are past the end of the file.



You can find out the state of the file you are editing
by typing a ^G. The editor will show you the name of
the file you are editing, the number of the current line,
the number of lines in the buffer, and the percentage of the
way through the buffer which you are. Try doing this now,
and remember the number of the line you are on. Give a
G command to get to the end and then another G
command to get back where you were.



You can also get back to a previous position by using
the command  (two back quotes). This is often more
convenient than G because it requires no advance
preparation. Try giving a G or a search with /
or ? and then a  to get back to where you
were. If you accidentally hit n or any command which
moves you far away from a context of interest, you can
quickly get back by hitting .



2.3. Moving around on the screen



Now try just moving the cursor around on the screen. If
your terminal has arrow keys (4 or 5 keys with arrows going
in each direction) try them and convince yourself that they
work. If you don't have working arrow keys, you can always
use h, j, k, and l. Experienced
users of vi prefer these keys to arrow keys, because
they are usually right underneath their fingers.



Hit the + key. Each time you do, notice that the
cursor advances to the next line in the file, at the first
non-white position on the line. The - key is like
+ but goes the other way.



These are very common keys for moving up and down lines
in the file. Notice that if you go off the bottom or top
with these keys then the screen will scroll down (and up if
possible) to bring a line at a time into view. The
RETURN key has the same effect as the
+ key.



Vi also has commands to take you to the top,
middle and bottom of the screen. H will take you to
the top (home) line on the screen. Try preceding it with a
number as in 3H. This will take you to the third line
on the screen. Many vi commands take preceding
numbers and do interesting things with them. Try M,
which takes you to the middle line on the screen, and
L, which takes you to the last line on the screen.
L also takes counts, thus 5L will take you to
the fifth line from the bottom.



2.4. Moving within a line



Now try picking a word on some line on the screen, not
the first word on the line. move the cursor using
RETURN and - to be on the line where
the word is. Try hitting the w key. This will advance
the cursor to the next word on the line. Try hitting the
b key to back up words in the line. Also try the
e key which advances you to the end of the current
word rather than to the beginning of the next word. Also try
SPACE (the space bar) which moves right one
character and the BS (backspace or ^H)
key which moves left one character. The key h works
as ^H does and is useful if you don't have a
BS key. (Also, as noted just above, l
will move to the right.)



If the line had punctuation in it you may have noticed
that that the w and b keys stopped at each
group of punctuation. You can also go back and forwards
words without stopping at punctuation by using W and
B rather than the lower case equivalents. Think of
these as bigger words. Try these on a few lines with
punctuation to see how they differ from the lower case
w and b.



The word keys wrap around the end of line, rather than
stopping at the end. Try moving to a word on a line below
where you are by repeatedly hitting w.



2.5. Summary






2.6. View



If you want to use the editor to look at a file, rather
than to make changes, invoke it as view instead of
vi. This will set the readonly option which
will prevent you from accidently overwriting the file.



3. Making simple changes



3.1. Inserting



One of the most useful commands is the i (insert)
command. After you type i, everything you type until
you hit ESC is inserted into the file. Try
this now; position yourself to some word in the file and try
inserting text before this word. If you are on an dumb
terminal it will seem, for a minute, that some of the
characters in your line have been overwritten, but they will
reappear when you hit ESC .



Now try finding a word which can, but does not, end in
an `s'. Position yourself at this word and type e
(move to end of word), then a for append and then `s
ESC ' to terminate the textual insert. This
sequence of commands can be used to easily pluralize a
word.



Try inserting and appending a few times to make sure you
understand how this works; i placing text to the left
of the cursor, a to the right.



It is often the case that you want to add new lines to
the file you are editing, before or after some specific line
in the file. Find a line where this makes sense and then
give the command o to create a new line after the
line you are on, or the command O to create a new
line before the line you are on. After you create a new line
in this way, text you type up to an ESC is
inserted on the new line.



Many related editor commands are invoked by the same
letter key and differ only in that one is given by a lower
case key and the other is given by an upper case key. In
these cases, the upper case key often differs from the lower
case key in its sense of direction, with the upper case key
working backward and/or up, while the lower case key moves
forward and/or down.



Whenever you are typing in text, you can give many lines
of input or just a few characters. To type in more than one
line of text, hit a RETURN at the middle of
your input. A new line will be created for text, and you can
continue to type. If you are on a slow and dumb terminal the
editor may choose to wait to redraw the tail of the screen,
and will let you type over the existing screen lines. This
avoids the lengthy delay which would occur if the editor
attempted to keep the tail of the screen always up to date.
The tail of the screen will be fixed up, and the missing
lines will reappear, when you hit ESC .



While you are inserting new text, you can use the
characters you normally use at the system command level
(usually ^H or #) to backspace over the last
character which you typed, and the character which you use
to kill input lines (usually @, ^X, or
^U) to erase the input you have typed on the current
line.






The character ^W will erase a whole word and
leave you after the space after the previous word; it is
useful for quickly backing up in an insert.



Notice that when you backspace during an insertion the
characters you backspace over are not erased; the cursor
moves backwards, and the characters remain on the display.
This is often useful if you are planning to type in
something similar. In any case the characters disappear when
when you hit ESC ; if you want to get rid of
them immediately, hit an ESC and then
a again.



Notice also that you can't erase characters which you
didn't insert, and that you can't backspace around the end
of a line. If you need to back up to the previous line to
make a correction, just hit ESC and move the
cursor back to the previous line. After making the
correction you can return to where you were and use the
insert or append command again.



3.2. Making small corrections



You can make small corrections in existing text quite
easily. Find a single character which is wrong or just pick
any character. Use the arrow keys to find the character, or
get near the character with the word motion keys and then
either backspace (hit the BS key or ^H
or even just h) or SPACE (using the
space bar) until the cursor is on the character which is
wrong. If the character is not needed then hit the x
key; this deletes the character from the file. It is
analogous to the way you x out characters when you
make mistakes on a typewriter (except it's not as
messy).



If the character is incorrect, you can replace it with
the correct character by giving the command
rc, where c is replaced by the correct
character. Finally if the character which is incorrect
should be replaced by more than one character, give the
command s which substitutes a string of characters,
ending with ESC , for it. If there are a
small number of characters which are wrong you can precede
s with a count of the number of characters to be
replaced. Counts are also useful with x to specify
the number of characters to be deleted.



3.3. More corrections: operators



You already know almost enough to make changes at a
higher level. All you need to know now is that the d
key acts as a delete operator. Try the command dw to
delete a word. Try hitting . a few times. Notice that
this repeats the effect of the dw. The command
. repeats the last command which made a change. You
can remember it by analogy with an ellipsis
`...'.



Now try db. This deletes a word backwards, namely
the preceding word. Try d SPACE . This
deletes a single character, and is equivalent to the
x command.



Another very useful operator is c or change. The
command cw thus changes the text of a single word.
You follow it by the replacement text ending with an
ESC . Find a word which you can change to
another, and try this now. Notice that the end of the text
to be changed was marked with the character `$' so that you
can see this as you are typing in the new material.



3.4. Operating on lines



It is often the case that you want to operate on lines.
Find a line which you want to delete, and type dd,
the d operator twice. This will delete the line. If
you are on a dumb terminal, the editor may just erase the
line on the screen, replacing it with a line with only an @
on it. This line does not correspond to any line in your
file, but only acts as a place holder. It helps to avoid a
lengthy redraw of the rest of the screen which would be
necessary to close up the hole created by the deletion on a
terminal without a delete line capability.



Try repeating the c operator twice; this will
change a whole line, erasing its previous contents and
replacing them with text you type up to an
ESC .






You can delete or change more than one line by preceding
the dd or cc with a count, i.e. 5dd
deletes 5 lines. You can also give a command like dL
to delete all the lines up to and including the last line on
the screen, or d3L to delete through the third from
the bottom line. Try some commands like this now.*






Notice that the editor lets you know when you change a
large number of lines so that you can see the extent of the
change. The editor will also always tell you when a change
you make affects text which you cannot see.



3.5. Undoing



Now suppose that the last change which you made was
incorrect; you could use the insert, delete and append
commands to put the correct material back. However, since it
is often the case that we regret a change or make a change
incorrectly, the editor provides a u (undo) command
to reverse the last change which you made. Try this a few
times, and give it twice in a row to notice that an u
also undoes a u.



The undo command lets you reverse only a single change.
After you make a number of changes to a line, you may decide
that you would rather have the original state of the line
back. The U command restores the current line to the
state before you started changing it.



You can recover text which you delete, even if undo will
not bring it back; see the section on recovering lost text
below.



3.6. Summary






4. Moving about; rearranging and duplicating text



4.1. Low level character motions



Now move the cursor to a line where there is a
punctuation or a bracketing character such as a parenthesis
or a comma or period. Try the command fx where
x is this character. This command finds the next
x character to the right of the cursor in the current
line. Try then hitting a ;, which finds the next
instance of the same character. By using the f
command and then a sequence of ;'s you can often get
to a particular place in a line much faster than with a
sequence of word motions or SPACE s. There is
also a F command, which is like f, but
searches backward. The ; command repeats F
also.



When you are operating on the text in a line it is often
desirable to deal with the characters up to, but not
including, the first instance of a character. Try
dfx for some x now and notice that the
x character is deleted. Undo this with u and
then try dtx; the t here stands for to,
i.e. delete up to the next x, but not the x.
The command T is the reverse of t.



When working with the text of a single line, an moves
the cursor to the first non-white position on the line, and
a $ moves it to the end of the line. Thus $a
will append new text at the end of the current line.



Your file may have tab (^I) characters in it.
These characters are represented as a number of spaces
expanding to a tab stop, where tab stops are every 8
positions.*






When the cursor is at a tab, it sits on the last of the
several spaces which represent that tab. Try moving the
cursor back and forth over tabs so you understand how this
works.



On rare occasions, your file may have nonprinting
characters in it. These characters are displayed in the same
way they are represented in this document, that is with a
two character code, the first character of which is `^'. On
the screen non-printing characters resemble a `^' character
adjacent to another, but spacing or backspacing over the
character will reveal that the two characters are, like the
spaces representing a tab character, a single character.



The editor sometimes discards control characters,
depending on the character and the setting of the
beautify option, if you attempt to insert them in
your file. You can get a control character in the file by
beginning an insert and then typing a ^V before the
control character. The ^V quotes the following
character, causing it to be inserted directly into the
file.



4.2. Higher level text objects



In working with a document it is often advantageous to
work in terms of sentences, paragraphs, and sections. The
operations ( and ) move to the beginning of
the previous and next sentences respectively. Thus the
command d) will delete the rest of the current
sentence; likewise d( will delete the previous
sentence if you are at the beginning of the current
sentence, or the current sentence up to where you are if you
are not at the beginning of the current sentence.



A sentence is defined to end at a `.', `!' or `?' which
is followed by either the end of a line, or by two spaces.
Any number of closing `)', `]', `"' and `' characters
may appear after the `.', `!' or `?' before the spaces or
end of line.



The operations { and } move over
paragraphs and the operations [[ and ]] move
over sections.






A paragraph begins after each empty line, and also at
each of a set of paragraph macros, specified by the pairs of
characters in the definition of the string valued option
paragraphs. The default setting for this option
defines the paragraph macros of the -ms and
-mm macro packages, i.e. the `.IP', `.LP', `.PP' and
`.QP', `.P' and `.LI' macros.






Each paragraph boundary is also a sentence boundary. The
sentence and paragraph commands can be given counts to
operate over groups of sentences and paragraphs.



Sections in the editor begin after each macro in the
sections option, normally `.NH', `.SH', `.H' and
`.HU', and each line with a formfeed ^L in the first
column. Section boundaries are always line and paragraph
boundaries also.



Try experimenting with the sentence and paragraph
commands until you are sure how they work. If you have a
large document, try looking through it using the section
commands. The section commands interpret a preceding count
as a different window size in which to redraw the screen at
the new location, and this window size is the base size for
newly drawn windows until another size is specified. This is
very useful if you are on a slow terminal and are looking
for a particular section. You can give the first section
command a small count to then see each successive section
heading in a small window.



4.3. Rearranging and duplicating text



The editor has a single unnamed buffer where the last
deleted or changed away text is saved, and a set of named
buffers a-z which you can use to save copies
of text and to move text around in your file and between
files.



The operator y yanks a copy of the object which
follows into the unnamed buffer. If preceded by a buffer
name, "xy, where x here is
replaced by a letter a-z, it places the text in the
named buffer. The text can then be put back in the file with
the commands p and P; p puts the text after or
below the cursor, while P puts the text before or
above the cursor.



If the text which you yank forms a part of a line, or is
an object such as a sentence which partially spans more than
one line, then when you put the text back, it will be placed
after the cursor (or before if you use P). If the
yanked text forms whole lines, they will be put back as
whole lines, without changing the current line. In this
case, the put acts much like a o or O
command.



Try the command YP. This makes a copy of the
current line and leaves you on this copy, which is placed
before the current line. The command Y is a
convenient abbreviation for yy. The command Yp
will also make a copy of the current line, and place it
after the current line. You can give Y a count of
lines to yank, and thus duplicate several lines; try
3YP.



To move text within the buffer, you need to delete it in
one place, and put it back in another. You can precede a
delete operation by the name of a buffer in which the text
is to be stored as in "a5dd deleting 5 lines
into the named buffer a. You can then move the cursor
to the eventual resting place of the these lines and do a
"ap or "aP to put them back. In
fact, you can switch and edit another file before you put
the lines back, by giving a command of the form :e
name CR where name is the name
of the other file you want to edit. You will have to write
back the contents of the current editor buffer (or discard
them) if you have made changes before the editor will let
you switch to the other file. An ordinary delete command
saves the text in the unnamed buffer, so that an ordinary
put can move it elsewhere. However, the unnamed buffer is
lost when you change files, so to move text from one file to
another you should use an unnamed buffer.



4.4. Summary.






5. High level commands



5.1. Writing, quitting, editing new files



So far we have seen how to enter vi and to write
out our file using either ZZ or :w
CR . The first exits from the editor,
(writing if changes were made), the second writes and stays
in the editor.



If you have changed the editor's copy of the file but do
not wish to save your changes, either because you messed up
the file or decided that the changes are not an improvement
to the file, then you can give the command :q!
CR to quit from the editor without writing
the changes. You can also reedit the same file (starting
over) by giving the command :e! CR .
These commands should be used only rarely, and with caution,
as it is not possible to recover the changes you have made
after you discard them in this manner.



You can edit a different file without leaving the editor
by giving the command :e name
CR . If you have not written out your file
before you try to do this, then the editor will tell you
this, and delay editing the other file. You can then give
the command :w CR to save your work
and then the :e name CR command
again, or carefully give the command :e! name
CR , which edits the other file discarding
the changes you have made to the current file. To have the
editor automatically save changes, include set
autowrite in your EXINIT, and use :n instead of
:e.



5.2. Escaping to a shell



You can get to a shell to execute a single command by
giving a vi command of the form :!cmd
CR . The system will run the single command
cmd and when the command finishes, the editor will
ask you to hit a RETURN to continue. When you
have finished looking at the output on the screen, you
should hit RETURN and the editor will clear
the screen and redraw it. You can then continue editing. You
can also give another : command when it asks you for
a RETURN ; in this case the screen will not
be redrawn.



If you wish to execute more than one command in the
shell, then you can give the command :sh
CR . This will give you a new shell, and when
you finish with the shell, ending it by typing a ^D,
the editor will clear the screen and continue.



On systems which support it, ^Z will suspend the
editor and return to the (top level) shell. When the editor
is resumed, the screen will be redrawn.



5.3. Marking and returning



The command  returned to the previous place after
a motion of the cursor by a command such as /,
? or G. You can also mark lines in the file
with single letter tags and return to these marks later by
naming the tags. Try marking the current line with the
command mx, where you should pick some letter
for x, say `a'. Then move the cursor to a different
line (any way you like) and hit a. The cursor will
return to the place which you marked. Marks last only until
you edit another file.



When using operators such as d and referring to
marked lines, it is often desirable to delete whole lines
rather than deleting to the exact position in the line
marked by m. In this case you can use the form
x rather than x. Used without an
operator, x will move to the first non-white
character of the marked line; similarly  moves to the
first non-white character of the line containing the
previous context mark .



5.4. Adjusting the screen



If the screen image is messed up because of a
transmission error to your terminal, or because some program
other than the editor wrote output to your terminal, you can
hit a ^L, the ASCII form-feed
character, to cause the screen to be refreshed.



On a dumb terminal, if there are @ lines in the middle
of the screen as a result of line deletion, you may get rid
of these lines by typing ^R to cause the editor to
retype the screen, closing up these holes.



Finally, if you wish to place a certain line on the
screen at the top middle or bottom of the screen, you can
position the cursor to that line, and then give a z
command. You should follow the z command with a
RETURN if you want the line to appear at the
top of the window, a . if you want it at the center,
or a - if you want it at the bottom.



6. Special topics



6.1. Editing on slow terminals



When you are on a slow terminal, it is important to
limit the amount of output which is generated to your screen
so that you will not suffer long delays, waiting for the
screen to be refreshed. We have already pointed out how the
editor optimizes the updating of the screen during
insertions on dumb terminals to limit the delays, and how
the editor erases lines to @ when they are deleted on dumb
terminals.



The use of the slow terminal insertion mode is
controlled by the slowopen option. You can force the
editor to use this mode even on faster terminals by giving
the command :se slow CR . If your
system is sluggish this helps lessen the amount of output
coming to your terminal. You can disable this option by
:se noslow CR .



The editor can simulate an intelligent terminal on a
dumb one. Try giving the command :se redraw
CR . This simulation generates a great deal
of output and is generally tolerable only on lightly loaded
systems and fast terminals. You can disable this by giving
the command :se noredraw CR .



The editor also makes editing more pleasant at low speed
by starting editing in a small window, and letting the
window expand as you edit. This works particularly well on
intelligent terminals. The editor can expand the window
easily when you insert in the middle of the screen on these
terminals. If possible, try the editor on an intelligent
terminal to see how this works.



You can control the size of the window which is redrawn
each time the screen is cleared by giving window sizes as
argument to the commands which cause large screen
motions:


     :  /  ?  [[  ]]    




Thus if you are searching for a particular instance of a
common string in a file you can precede the first search
command by a small number, say 3, and the editor will draw
three line windows around each instance of the string which
it locates.



You can easily expand or contract the window, placing
the current line as you choose, by giving a number on a
z command, after the z and before the
following RETURN , . or -. Thus
the command z5. redraws the screen with the current
line in the center of a five line window.






If the editor is redrawing or otherwise updating large
portions of the display, you can interrupt this updating by
hitting a DEL or RUB as usual.
If you do this you may partially confuse the editor about
what is displayed on the screen. You can still edit the text
on the screen if you wish; clear up the confusion by hitting
a ^L; or move or search again, ignoring the current
state of the display.



See section 7.8 on open mode for another way to
use the vi command set on slow terminals.



6.2. Options, set, and editor startup files



The editor has a set of options, some of which have been
mentioned above. The most useful options are given in the
following table.



The options are of three kinds: numeric options, string
options, and toggle options. You can set numeric and string
options by a statement of the form


     set opt=val




and toggle options can be set or unset by statements of
one of the forms


     set opt
     set noopt







These statements can be placed in your EXINIT in your
environment, or given while you are running vi by
preceding them with a : and following them with a
CR .



You can get a list of all options which you have changed
by the command :set CR , or the value
of a single option by the command :set
opt? CR . A list of all
possible options and their values is generated by :set
all CR . Set can be abbreviated
se. Multiple options can be placed on one line, e.g.
:se ai aw nu CR .



Options set by the set command only last while
you stay in the editor. It is common to want to have certain
options set whenever you use the editor. This can be
accomplished by creating a list of ex commands






which are to be run every time you start up ex,
edit, or vi. A typical list includes a
set command, and possibly a few map commands.
Since it is advisable to get these commands on one line,
they can be separated with the | character, for example:


     set ai aw terse|map @ dd|map # x




which sets the options autoindent,
autowrite, terse, (the set command),
makes @ delete a line, (the first map), and makes #
delete a character, (the second map). (See section
6.9 for a description of the map command) This string
should be placed in the variable EXINIT in your environment.
If you use the shell csh, put this line in the file
.login in your home directory:


     setenv EXINIT set ai aw terse|map @ dd|map # x




If you use the standard shell sh, put these lines
in the file .profile in your home directory:


     EXINIT=set ai aw terse|map @ dd|map # x
     export EXINIT




Of course, the particulars of the line would depend on
which options you wanted to set.



6.3. Recovering lost lines



You might have a serious problem if you delete a number
of lines and then regret that they were deleted. Despair
not, the editor saves the last 9 deleted blocks of text in a
set of numbered registers 1-9. You can get the n'th
previous deleted text back in your file by the command
"np. The " here says that a buffer
name is to follow, n is the number of the buffer you
wish to try (use the number 1 for now), and p is the
put command, which puts text in the buffer after the cursor.
If this doesn't bring back the text you wanted, hit u
to undo this and then . (period) to repeat the put
command. In general the . command will repeat the
last change you made. As a special case, when the last
command refers to a numbered text buffer, the .
command increments the number of the buffer before repeating
the command. Thus a sequence of the form


     "1pu.u.u.




will, if repeated long enough, show you all the deleted
text which has been saved for you. You can omit the u
commands here to gather up all this text in the buffer, or
stop after any . command to keep just the then
recovered text. The command P can also be used rather
than p to put the recovered text before rather than
after the cursor.



6.4. Recovering lost files



If the system crashes, you can recover the work you were
doing to within a few changes. You will normally receive
mail when you next login giving you the name of the file
which has been saved for you. You should then change to the
directory where you were when the system crashed and give a
command of the form:


     % vi -r name




replacing name with the name of the file which
you were editing. This will recover your work to a point
near where you left off.






You can get a listing of the files which are saved for
you by giving the command:


     % vi -r




If there is more than one instance of a particular file
saved, the editor gives you the newest instance each time
you recover it. You can thus get an older saved copy back by
first recovering the newer copies.



For this feature to work, vi must be correctly
installed by a super user on your system, and the
mail program must exist to receive mail. The
invocation ``vi -r'' will not always list all saved
files, but they can be recovered even if they are not
listed.



6.5. Continuous text input



When you are typing in large amounts of text it is
convenient to have lines broken near the right margin
automatically. You can cause this to happen by giving the
command :se wm=10 CR . This causes all
lines to be broken at a space at least 10 columns from the
right hand edge of the screen.



If the editor breaks an input line and you wish to put
it back together you can tell it to join the lines with
J. You can give J a count of the number of
lines to be joined as in 3J to join 3 lines. The
editor supplies white space, if appropriate, at the juncture
of the joined lines, and leaves the cursor at this white
space. You can kill the white space with x if you
don't want it.



6.6. Features for editing programs



The editor has a number of commands for editing
programs. The thing that most distinguishes editing of
programs from editing of text is the desirability of
maintaining an indented structure to the body of the
program. The editor has a autoindent facility for
helping you generate correctly indented programs.



To enable this facility you can give the command :se
ai CR . Now try opening a new line with
o and type some characters on the line after a few
tabs. If you now start another line, notice that the editor
supplies white space at the beginning of the line to line it
up with the previous line. You cannot backspace over this
indentation, but you can use ^D key to backtab over
the supplied indentation.



Each time you type ^D you back up one position,
normally to an 8 column boundary. This amount is settable;
the editor has an option called shiftwidth which you
can set to change this value. Try giving the command :se
sw=4 CR and then experimenting with
autoindent again.



For shifting lines in the program left and right, there
are operators < and >. These shift the
lines you specify right or left by one shiftwidth.
Try << and >> which shift one line
left or right, and <L and >L shifting
the rest of the display left and right.



If you have a complicated expression and wish to see how
the parentheses match, put the cursor at a left or right
parenthesis and hit %. This will show you the
matching parenthesis. This works also for braces { and },
and brackets [ and ].



If you are editing C programs, you can use the [[
and ]] keys to advance or retreat to a line starting
with a {, i.e. a function declaration at a time. When
]] is used with an operator it stops after a line
which starts with }; this is sometimes useful with
y]].



6.7. Filtering portions of the buffer



You can run system commands over portions of the buffer
using the operator !. You can use this to sort lines
in the buffer, or to reformat portions of the buffer with a
pretty-printer. Try typing in a list of random words, one
per line and ending them with a blank line. Back up to the
beginning of the list, and then give the command
!}sort CR . This says to sort the next
paragraph of material, and the blank line ends a
paragraph.



6.8. Commands for editing LISP



If you are editing a LISP program you
should set the option lisp by doing :se lisp
CR . This changes the ( and )
commands to move backward and forward over s-expressions.
The { and } commands are like ( and
) but don't stop at atoms. These can be used to skip
to the next list, or through a comment quickly.



The autoindent option works differently for
LISP , supplying indent to align at the first
argument to the last open list. If there is no such argument
then the indent is two spaces more than the last level.



There is another option which is useful for typing in
LISP , the showmatch option. Try
setting it with :se sm CR and then try
typing a `(' some words and then a `)'. Notice that the
cursor shows the position of the `(' which matches the `)'
briefly. This happens only if the matching `(' is on the
screen, and the cursor stays there for at most one
second.



The editor also has an operator to realign existing
lines as though they had been typed in with lisp and
autoindent set. This is the = operator. Try
the command =% at the beginning of a function. This
will realign all the lines of the function declaration.



When you are editing LISP ,, the
[[ and ]] advance and retreat to lines beginning with
a (, and are useful for dealing with entire function
definitions.



6.9. Macros



Vi has a parameterless macro facility, which lets
you set it up so that when you hit a single keystroke, the
editor will act as though you had hit some longer sequence
of keys. You can set this up if you find yourself typing the
same sequence of commands repeatedly.



Briefly, there are two flavors of macros:






a)
Ones where you put the macro body in a buffer register, say x. You can then type @x to invoke the macro. The @ may be followed by another @ to repeat the last macro.







b)
You can use the map command from vi (typically
in your EXINIT) with a command of the
form:








     :map lhs rhsCR

mapping lhs into rhs. There are restrictions: lhs should be one keystroke (either 1 character or one function key) since it must be entered within one second (unless notimeout is set, in which case you can type it as slowly as you wish, and vi will wait for you to finish it before it echoes anything). The lhs can be no longer than 10 characters, the rhs no longer than 100. To get a space, tab or newline into lhs or rhs you should escape them with a ^V. (It may be necessary to double the ^V if the map command is given inside vi, rather than in ex.) Spaces and tabs inside the rhs need not be escaped.



Thus to make the q key write and exit the editor,
you can give the command


     :map q :wq^V^VCR CR




which means that whenever you type q, it will be
as though you had typed the four characters :wq
CR . A ^V's is needed because without
it the CR would end the : command,
rather than becoming part of the map definition.
There are two ^V's because from within vi, two
^V's must be typed to get one. The first
CR is part of the rhs, the second
terminates the : command.



Macros can be deleted with


     unmap lhs




If the lhs of a macro is ``#0'' through ``#9'',
this maps the particular function key instead of the 2
character ``#'' sequence. So that terminals without function
keys can access such definitions, the form ``#x'' will mean
function key x on all terminals (and need not be
typed within one second.) The character ``#'' can be changed
by using a macro in the usual way:


     :map ^V^V^I #




to use tab, for example. (This won't affect the
map command, which still uses #, but just the
invocation from visual mode.



The undo command reverses an entire macro call as a
unit, if it made any changes.



Placing a `!' after the word map causes the
mapping to apply to input mode, rather than command mode.
Thus, to arrange for ^T to be the same as 4 spaces in
input mode, you can type:


     :map ^T ^Vb/b/b/b/




where b/ is a blank. The ^V is necessary
to prevent the blanks from being taken as white space
between the lhs and rhs.



7. Word Abbreviations



A feature similar to macros in input mode is word
abbreviation. This allows you to type a short word and have
it expanded into a longer word or words. The commands are
:abbreviate and :unabbreviate (:ab and
:una) and have the same syntax as :map. For
example:


     :ab eecs Electrical Engineering and Computer Sciences




causes the word `eecs' to always be changed into the
phrase `Electrical Engineering and Computer Sciences'. Word
abbreviation is different from macros in that only whole
words are affected. If `eecs' were typed as part of a larger
word, it would be left alone. Also, the partial word is
echoed as it is typed. There is no need for an abbreviation
to be a single keystroke, as it should be with a macro.



7.1. Abbreviations



The editor has a number of short commands which
abbreviate longer commands which we have introduced here.
You can find these commands easily on the quick reference
card. They often save a bit of typing and you can learn them
as convenient.



8. Nitty-gritty details



8.1. Line representation in the display



The editor folds long logical lines onto many physical
lines in the display. Commands which advance lines advance
logical lines and will skip over all the segments of a line
in one motion. The command | moves the cursor to a
specific column, and may be useful for getting near the
middle of a long line to split it in half. Try 80| on
a line which is more than 80 columns long.






The editor only puts full lines on the display; if there
is not enough room on the display to fit a logical line, the
editor leaves the physical line empty, placing only an @ on
the line as a place holder. When you delete lines on a dumb
terminal, the editor will often just clear the lines to @ to
save time (rather than rewriting the rest of the screen.)
You can always maximize the information on the screen by
giving the ^R command.



If you wish, you can have the editor place line numbers
before each line on the display. Give the command :se
nu CR to enable this, and the command
:se nonu CR to turn it off. You can
have tabs represented as ^I and the ends of lines
indicated with `$' by giving the command :se list
CR ; :se nolist CR
turns this off.



Finally, lines consisting of only the character `~' are
displayed when the last line in the file is in the middle of
the screen. These represent physical lines which are past
the logical end of file.



8.2. Counts



Most vi commands will use a preceding count to
affect their behavior in some way. The following table gives
the common ways in which the counts are used:










The editor maintains a notion of the current default
window size. On terminals which run at speeds greater than
1200 baud the editor uses the full terminal screen. On
terminals which are slower than 1200 baud (most dialup lines
are in this group) the editor uses 8 lines as the default
window size. At 1200 baud the default is 16 lines.



This size is the size used when the editor clears and
refills the screen after a search or other motion moves far
from the edge of the current window. The commands which take
a new window size as count all often cause the screen to be
redrawn. If you anticipate this, but do not need as large a
window as you are currently using, you may wish to change
the screen size by specifying the new size before these
commands. In any case, the number of lines used on the
screen will expand if you move off the top with a -
or similar command or off the bottom with a command such as
RETURN or ^D. The window will revert
to the last specified size the next time it is cleared and
refilled.






The scroll commands ^D and ^U likewise
remember the amount of scroll last specified, using half the
basic window size initially. The simple insert commands use
a count to specify a repetition of the inserted text. Thus
10a+---- ESC will insert a grid-like
string of text. A few commands also use a preceding count as
a line or column number.



Except for a few commands which ignore any counts (such
as ^R), the rest of the editor commands use a count
to indicate a simple repetition of their effect. Thus
5w advances five words on the current line, while
5 RETURN advances five lines. A very
useful instance of a count as a repetition is a count given
to the . command, which repeats the last changing
command. If you do dw and then 3., you will
delete first one and then three words. You can then delete
two more words with 2..



8.3. More file manipulation commands



The following table lists the file manipulation commands
which you can use when you are in vi.










All of these commands are followed by a
CR or ESC . The most basic
commands are :w and :e. A normal editing
session on a single file will end with a ZZ command.
If you are editing for a long period of time you can give
:w commands occasionally after major amounts of
editing, and then finish with a ZZ. When you edit
more than one file, you can finish with one with a :w
and start editing a new file by giving a :e command,
or set autowrite and use :n <file>.



If you make changes to the editor's copy of a file, but
do not wish to write them back, then you must give an
! after the command you would otherwise use; this
forces the editor to discard any changes you have made. Use
this carefully.



The :e command can be given a + argument
to start at the end of the file, or a +n
argument to start at line n. In actuality, n
may be any editor command not containing a space, usefully a
scan like +/pat or +?pat. In
forming new names to the e command, you can use the
character % which is replaced by the current file
name, or the character # which is replaced by the
alternate file name. The alternate file name is generally
the last name you typed other than the current file. Thus if
you try to do a :e and get a diagnostic that you
haven't written the file, you can give a :w command
and then a :e # command to redo the previous
:e.



You can write part of the buffer to a file by finding
out the lines that bound the range to be written using
^G, and giving these numbers after the : and
before the w, separated by ,'s. You can also
mark these lines with m and then use an address of
the form x,y on the w
command here.



You can read another file into the buffer after the
current line by using the :r command. You can
similarly read in the output from a command, just use
!cmd instead of a file name.



If you wish to edit a set of files in succession, you
can give all the names on the command line, and then edit
each one in turn using the command :n. It is also
possible to respecify the list of files to be edited by
giving the :n command a list of file names, or a
pattern to be expanded as you would have given it on the
initial vi command.



If you are editing large programs, you will find the
:ta command very useful. It utilizes a data base of
function names and their locations, which can be created by
programs such as ctags, to quickly find a function
whose name you give. If the :ta command will require
the editor to switch files, then you must :w or
abandon any changes before switching. You can repeat the
:ta command without any arguments to look for the
same tag again.



8.4. More about searching for strings



When you are searching for strings in the file with
/ and ?, the editor normally places you at the
next or previous occurrence of the string. If you are using
an operator such as d, c or y, then you
may well wish to affect lines up to the line before the line
containing the pattern. You can give a search of the form
/pat/-n to refer to the
n'th line before the next line containing pat,
or you can use + instead of - to refer to the
lines after the one containing pat. If you don't give
a line offset, then the editor will affect characters up to
the match place, rather than whole lines; thus use ``+0'' to
affect to the line which matches.



You can have the editor ignore the case of words in the
searches it does by giving the command :se ic
CR . The command :se noic
CR turns this off.



Strings given to searches may actually be regular
expressions. If you do not want or need this facility, you
should


     set nomagic




in your EXINIT. In this case, only the characters and
$ are special in patterns. The character \ is
also then special (as it is most everywhere in the system),
and may be used to get at the an extended pattern matching
facility. It is also necessary to use a \ before a /
in a forward scan or a ? in a backward scan, in any
case. The following table gives the extended forms when
magic is set.










If you use nomagic mode, then the . [ and
* primitives are given with a preceding .



8.5. More about input mode



There are a number of characters which you can use to
make corrections during input mode. These are summarized in
the following table.










The most usual way of making corrections to input is by
typing ^H to correct a single character, or by typing
one or more ^W's to back over incorrect words. If you
use # as your erase character in the normal system,
it will work like ^H.



Your system kill character, normally @, ^X
or ^U, will erase all the input you have given on the
current line. In general, you can neither erase input back
around a line boundary nor can you erase characters which
you did not insert with this insertion command. To make
corrections on the previous line after a new line has been
started you can hit ESC to end the insertion,
move over and make the correction, and then return to where
you were to continue. The command A which appends at
the end of the current line is often useful for
continuing.



If you wish to type in your erase or kill character (say
# or @) then you must precede it with a \, just as
you would do at the normal system command level. A more
general way of typing non-printing characters into the file
is to precede them with a ^V. The ^V echoes as
a character on which the cursor rests. This indicates that
the editor expects you to type a control character. In fact
you may type any character and it will be inserted into the
file at that point.*






If you are using autoindent you can backtab over
the indent which it supplies by typing a ^D. This
backs up to a shiftwidth boundary. This only works
immediately after the supplied autoindent.



When you are using autoindent you may wish to
place a label at the left margin of a line. The way to do
this easily is to type and then ^D. The editor will
move the cursor to the left margin for one line, and restore
the previous indent on the next. You can also type a
0 followed immediately by a ^D if you wish to
kill all the indent and not have it come back on the next
line.



8.6. Upper case only terminals



If your terminal has only upper case, you can still use
vi by using the normal system convention for typing
on such a terminal. Characters which you normally type are
converted to lower case, and you can type upper case letters
by preceding them with a . The characters { ~ } | are not
available on such terminals, but you can escape them as \ )
! \(&acute;). These characters are represented on the
display in the same way they are typed.






8.7. Vi and ex



Vi is actually one mode of editing within the
editor ex. When you are running vi you can
escape to the line oriented editor of ex by giving
the command Q. All of the : commands which
were introduced above are available in ex. Likewise,
most ex commands can be invoked from vi using
:. Just give them without the : and follow them with
a CR .



In rare instances, an internal error may occur in
vi. In this case you will get a diagnostic and be
left in the command mode of ex. You can then save
your work and quit if you wish by giving a command x
after the : which ex prompts you with, or you
can reenter vi by giving ex a vi
command.



There are a number of things which you can do more
easily in ex than in vi. Systematic changes in
line oriented material are particularly easy. You can read
the advanced editing documents for the editor ed to
find out a lot more about this style of editing. Experienced
users often mix their use of ex command mode and
vi command mode to speed the work they are doing.



8.8. Open mode: vi on hardcopy terminals and ``glass tty's''



If you are on a hardcopy terminal or a terminal which
does not have a cursor which can move off the bottom line,
you can still use the command set of vi, but in a
different mode. When you give a vi command, the
editor will tell you that it is using open mode. This
name comes from the open command in ex, which
is used to get into the same mode.



The only difference between visual mode and
open mode is the way in which the text is
displayed.



In open mode the editor uses a single line window
into the file, and moving backward and forward in the file
causes new lines to be displayed, always below the current
line. Two commands of vi work differently in
open: z and ^R. The z command
does not take parameters, but rather draws a window of
context around the current line and then returns you to the
current line.



If you are on a hardcopy terminal, the ^R command
will retype the current line. On such terminals, the editor
normally uses two lines to represent the current line. The
first line is a copy of the line as you started to edit it,
and you work on the line below this line. When you delete
characters, the editor types a number of 's to show you the
characters which are deleted. The editor also reprints the
current line soon after such changes so that you can see
what the line looks like again.



It is sometimes useful to use this mode on very slow
terminals which can support vi in the full screen
mode. You can do this by entering ex and using an
open command.



Acknowledgements



Bruce Englar encouraged the early development of this
display editor. Peter Kessler helped bring sanity to version
2's command layout. Bill Joy wrote versions 1 and 2.0
through 2.7, and created the framework that users see in the
present editor. Mark Horton added macros and other features
and made the editor work on a large number of terminals and
Unix systems.



Appendix: character functions



This appendix gives the uses the editor makes of each
character. The characters are presented in their order in
the ASCII character set: Control characters
come first, then most special characters, then the digits,
upper and then lower case characters.



For each character we tell a meaning it has as a command
and any meaning it has during an insert. If it has only
meaning as a command, then only this is discussed. Section
numbers in parentheses indicate where the character is
discussed; a `f' after the section number means that the
character is mentioned in a footnote.






^@
Not a command character. If typed as the first character of an insertion it is replaced with the last text inserted, and the insert terminates. Only 128 characters are saved from the last insert; if more characters were inserted the mechanism is not available. A ^@ cannot be part of the file due to the editor implementation (7.5f).







^A
Unused.







^B
Backward window. A count specifies repetition. Two lines of
continuity are kept if possible (2.1, 6.1,
7.2).







^C
Unused.







^D
As a command, scrolls down a half-window of text. A count
gives the number of (logical) lines to scroll, and is
remembered for future ^D and ^U commands (2.1,
7.2). During an insert, backtabs over autoindent
white space at the beginning of a line (6.6, 7.5); this
white space cannot be backspaced over.







^E
Exposes one more line below the current screen in the file,
leaving the cursor where it is if possible. (Version 3
only.)







^F
Forward window. A count specifies repetition. Two lines of
continuity are kept if possible (2.1, 6.1,
7.2).







^G
Equivalent to :f CR , printing the
current file, whether it has been modified, the current line
number and the number of lines in the file, and the
percentage of the way through the file that you
are.







^H ( BS )
Same as left arrow. (See h). During an insert,
eliminates the last input character, backing over it but not
erasing it; it remains so you can see what you typed if you
wish to type something only slightly different (3.1,
7.5).







^I ( TAB )
Not a command character. When inserted it prints as some
number of spaces. When the cursor is at a tab character it
rests at the last of the spaces which represent the tab. The
spacing of tabstops is controlled by the tabstop
option (4.1, 6.6).







^J ( LF )
Same as down arrow (see j).







^K
Unused.







^L
The ASCII formfeed character, this causes the
screen to be cleared and redrawn. This is useful after a
transmission error, if characters typed by a program other
than the editor scramble the screen, or after output is
stopped by an interrupt (5.4, 7.2f).







^M ( CR )
A carriage return advances to the next line, at the first
non-white position in the line. Given a count, it advances
that many lines (2.3). During an insert, a CR
causes the insert to continue onto another line
(3.1).







^N
Same as down arrow (see j).







^O
Unused.







^P
Same as up arrow (see k).







^Q
Not a command character. In input mode, ^Q quotes the
next character, the same as ^V, except that some
teletype drivers will eat the ^Q so that the editor
never sees it.







^R
Redraws the current screen, eliminating logical lines not
corresponding to physical lines (lines with only a single @
character on them). On hardcopy terminals in open
mode, retypes the current line (5.4, 7.2, 7.8).







^S
Unused. Some teletype drivers use ^S to suspend
output until pressed.^Qis







^T
Not a command character. During an insert, with
autoindent set and at the beginning of the line,
inserts shiftwidth white space.







^U
Scrolls the screen up, inverting ^D which scrolls
down. Counts work as they do for ^D, and the previous
scroll amount is common to both. On a dumb terminal,
^U will often necessitate clearing and redrawing the
screen further back in the file (2.1, 7.2).







^V
Not a command character. In input mode, quotes the next
character so that it is possible to insert non-printing and
special characters into the file (4.2, 7.5).







^W
Not a command character. During an insert, backs up as
b would in command mode; the deleted characters
remain on the display (see ^H) (7.5).







^X
Unused.







^Y
Exposes one more line above the current screen, leaving the
cursor where it is if possible. (No mnemonic value for this
key; however, it is next to ^U which scrolls up a
bunch.) (Version 3 only.)







^Z
If supported by the Unix system, stops the editor, exiting
to the top level shell. Same as :stop
CR . Otherwise, unused.







^[ ( ESC )
Cancels a partially formed command, such as a z when
no following character has yet been given; terminates inputs
on the last line (read by commands such as : / and
?); ends insertions of new text into the buffer. If
an ESC is given when quiescent in command
state, the editor rings the bell or flashes the screen. You
can thus hit ESC if you don't know what is
happening till the editor rings the bell. If you don't know
if you are in insert mode you can type ESC
a, and then material to be input; the material will
be inserted correctly whether or not you were in insert mode
when you started (1.5, 3.1, 7.5).







^\
Unused.







^]
Searches for the word which is after the cursor as a tag.
Equivalent to typing :ta, this word, and then a
CR . Mnemonically, this command is ``go right
to'' (7.3).







^
Equivalent to :e # CR , returning to
the previous position in the last edited file, or editing a
file which you specified if you got a `No write since last
change diagnostic' and do not want to have to type the file
name again (7.3). (You have to do a :w before
^ will work in this case. If you do not wish to write
the file you should do :e! # CR
instead.)







^_
Unused. Reserved as the command character for the Tektronix
4025 and 4027 terminal.







SPACE
Same as right arrow (see l).







!
An operator, which processes lines from the buffer with
reformatting commands. Follow ! with the object to be
processed, and then the command name terminated by
CR . Doubling ! and preceding it by a
count causes count lines to be filtered; otherwise the count
is passed on to the object after the !. Thus
2!}fmt CR reformats the next
two paragraphs by running them through the program
fmt. If you are working on LISP , the
command !%grind CR
,*









given at the beginning of a function, will run the text of the function through the LISP grinder (6.7, 7.3). To read a file or the output of a command into the buffer use :r (7.3). To simply execute a command use :! (7.3).







"
Precedes a named buffer specification. There are named
buffers 1-9 used for saving deleted text and named
buffers a-z into which you can place text (4.3,
6.3)







#
The macro character which, when followed by a number, will
substitute for a function key on terminals without function
keys (6.9). In input mode, if this is your erase character,
it will delete the last character you typed in input mode,
and must be preceded with a \ to insert it, since it
normally backs over the last input character you
gave.







$
Moves to the end of the current line. If you :se list
CR , then the end of each line will be shown
by printing a $ after the end of the displayed text
in the line. Given a count, advances to the count'th
following end of line; thus 2$ advances to the end of
the following line.







%
Moves to the parenthesis or brace { } which balances
the parenthesis or brace at the current cursor
position.







&
A synonym for :& CR , by analogy
with the ex & command.







When followed by a  returns to the previous context
at the beginning of a line. The previous context is set
whenever the current line is moved in a non-relative way.
When followed by a letter a-z, returns to the
line which was marked with this letter with a m
command, at the first non-white character in the line. (2.2,
5.3). When used with an operator such as d, the
operation takes place over complete lines; if you use
, the operation takes place from the exact marked
place to the current cursor position within the
line.







(
Retreats to the beginning of a sentence, or to the beginning
of a LISP s-expression if the lisp
option is set. A sentence ends at a . ! or ?
which is followed by either the end of a line or by two
spaces. Any number of closing ) ] " and 
characters may appear after the . ! or ?, and
before the spaces or end of line. Sentences also begin at
paragraph and section boundaries (see { and [[
below). A count advances that many sentences (4.2,
6.8).







)
Advances to the beginning of a sentence. A count repeats the
effect. See ( above for the definition of a sentence
(4.2, 6.8).







*
Unused.







+
Same as CR when used as a
command.







,
Reverse of the last f F t or T command,
looking the other way in the current line. Especially useful
after hitting too many ; characters. A count repeats
the search.







-
Retreats to the previous line at the first non-white
character. This is the inverse of + and
RETURN . If the line moved to is not on the
screen, the screen is scrolled, or cleared and redrawn if
this is not possible. If a large amount of scrolling would
be required the screen is also cleared and redrawn, with the
current line at the center (2.3).







.
Repeats the last command which changed the buffer.
Especially useful when deleting words or lines; you can
delete some words/lines and then hit . to delete more
and more words/lines. Given a count, it passes it on to the
command being repeated. Thus after a 2dw, 3.
deletes three words (3.3, 6.3, 7.2, 7.4).







/
Reads a string from the last line on the screen, and scans
forward for the next occurrence of this string. The normal
input editing sequences may be used during the input on the
bottom line; an returns to command state without ever
searching. The search begins when you hit CR
to terminate the pattern; the cursor moves to the beginning
of the last line to indicate that the search is in progress;
the search may then be terminated with a DEL
or RUB , or by backspacing when at the
beginning of the bottom line, returning the cursor to its
initial position. Searches normally wrap end-around to find
a string anywhere in the buffer.







When used with an operator the enclosed region is normally
affected. By mentioning an offset from the line matched by
the pattern you can force whole lines to be affected. To do
this give a pattern with a closing a closing / and
then an offset +n or
-n.







To include the character / in the search string, you
must escape it with a preceding \. A at the beginning
of the pattern forces the match to occur at the beginning of
a line only; this speeds the search. A $ at the end
of the pattern forces the match to occur at the end of a
line only. More extended pattern matching is available, see
section 7.4; unless you set nomagic in your
.exrc file you will have to preceed the characters
. [ * and ~ in the search pattern with a
\ to get them to work as you would naively expect
(1.5, 2,2, 6.1, 7.2, 7.4).







0
Moves to the first character on the current line. Also used,
in forming numbers, after an initial
1-9.







1-9
Used to form numeric arguments to commands (2.3,
7.2).







:
A prefix to a set of commands for file and option
manipulation and escapes to the system. Input is given on
the bottom line and terminated with an CR ,
and the command then executed. You can return to where you
were by hitting DEL or RUB if
you hit : accidentally (see primarily 6.2 and
7.3).







;
Repeats the last single character find which used f F
t or T. A count iterates the basic scan
(4.1).







<
An operator which shifts lines left one shiftwidth,
normally 8 spaces. Like all operators, affects lines when
repeated, as in <<. Counts are passed through
to the basic object, thus 3<< shifts three
lines (6.6, 7.2).







=
Reindents line for LISP , as though they were
typed in with lisp and autoindent set
(6.8).







>
An operator which shifts lines right one shiftwidth,
normally 8 spaces. Affects lines when repeated as in
>>. Counts repeat the basic object (6.6,
7.2).







?
Scans backwards, the opposite of /. See the /
description above for details on scanning (2.2, 6.1,
7.4).







@
A macro character (6.9). If this is your kill character, you
must escape it with a \ to type it in during input mode, as
it normally backs over the input you have given on the
current line (3.1, 3.4, 7.5).







A
Appends at the end of line, a synonym for $a
(7.2).







B
Backs up a word, where words are composed of non-blank
sequences, placing the cursor at the beginning of the word.
A count repeats the effect (2.4).







C
Changes the rest of the text on the current line; a synonym
for c$.







D
Deletes the rest of the text on the current line; a synonym
for d$.







E
Moves forward to the end of a word, defined as blanks and
non-blanks, like B and W. A count repeats the
effect.







F
Finds a single following character, backwards in the current
line. A count repeats this search that many times
(4.1).







G
Goes to the line number given as preceding argument, or the
end of the file if no preceding count is given. The screen
is redrawn with the new current line in the center if
necessary (7.2).







H
Home arrow. Homes the cursor to the top line on the
screen. If a count is given, then the cursor is moved to the
count'th line on the screen. In any case the cursor is moved
to the first non-white character on the line. If used as the
target of an operator, full lines are affected (2.3,
3.2).







I
Inserts at the beginning of a line; a synonym for
i.







J
Joins together lines, supplying appropriate white space: one
space between words, two spaces after a ., and no
spaces at all if the first character of the joined on line
is ). A count causes that many lines to be joined
rather than the default two (6.5, 7.1f).







K
Unused.







L
Moves the cursor to the first non-white character of the
last line on the screen. With a count, to the first
non-white of the count'th line from the bottom. Operators
affect whole lines when used with L
(2.3).







M
Moves the cursor to the middle line on the screen, at the
first non-white position on the line (2.3).







N
Scans for the next match of the last pattern given to
/ or ?, but in the reverse direction; this is
the reverse of n.







O
Opens a new line above the current line and inputs text
there up to an ESC . A count can be used on
dumb terminals to specify a number of lines to be opened;
this is generally obsolete, as the slowopen option
works better (3.1).







P
Puts the last deleted text back before/above the cursor. The
text goes back as whole lines above the cursor if it was
deleted as whole lines. Otherwise the text is inserted
between the characters before and at the cursor. May be
preceded by a named buffer specification
"x to retrieve the contents of the
buffer; buffers 1-9 contain deleted material,
buffers a-z are available for general use
(6.3).







Q
Quits from vi to ex command mode. In this
mode, whole lines form commands, ending with a
RETURN . You can give all the :
commands; the editor supplies the : as a prompt
(7.7).







R
Replaces characters on the screen with characters you type
(overlay fashion). Terminates with an ESC
.







S
Changes whole lines, a synonym for cc. A count
substitutes for that many lines. The lines are saved in the
numeric buffers, and erased on the screen before the
substitution begins.







T
Takes a single following character, locates the character
before the cursor in the current line, and places the cursor
just after that character. A count repeats the effect. Most
useful with operators such as d (4.1).







U
Restores the current line to its state before you started
changing it (3.5).







V
Unused.







W
Moves forward to the beginning of a word in the current
line, where words are defined as sequences of
blank/non-blank characters. A count repeats the effect
(2.4).







X
Deletes the character before the cursor. A count repeats the
effect, but only characters on the current line are
deleted.







Y
Yanks a copy of the current line into the unnamed buffer, to
be put back by a later p or P; a very useful
synonym for yy. A count yanks that many lines. May be
preceded by a buffer name to put lines in that buffer
(7.4).







ZZ
Exits the editor. (Same as :x CR .) If
any changes have been made, the buffer is written out to the
current file. Then the editor quits.







[[
Backs up to the previous section boundary. A section begins
at each macro in the sections option, normally a
`.NH' or `.SH' and also at lines which which start with a
formfeed ^L. Lines beginning with { also stop
[[; this makes it useful for looking backwards, a
function at a time, in C programs. If the option lisp
is set, stops at each ( at the beginning of a line,
and is thus useful for moving backwards at the top level
LISP objects. (4.2, 6.1, 6.6,
7.2).







\
Unused.







]]
Forward to a section boundary, see [[ for a
definition (4.2, 6.1, 6.6, 7.2).







Moves to the first non-white position on the current line
(4.4).







_
Unused.







When followed by a  returns to the previous context.
The previous context is set whenever the current line is
moved in a non-relative way. When followed by a letter
a-z, returns to the position which was marked
with this letter with a m command. When used with an
operator such as d, the operation takes place from
the exact marked place to the current position within the
line; if you use , the operation takes place over
complete lines (2.2, 5.3).







a
Appends arbitrary text after the current cursor position;
the insert can continue onto multiple lines by using
RETURN within the insert. A count causes the
inserted text to be replicated, but only if the inserted
text is all on one line. The insertion terminates with an
ESC (3.1, 7.2).







b
Backs up to the beginning of a word in the current line. A
word is a sequence of alphanumerics, or a sequence of
special characters. A count repeats the effect
(2.4).







c
An operator which changes the following object, replacing it
with the following input text up to an ESC .
If more than part of a single line is affected, the text
which is changed away is saved in the numeric named buffers.
If only part of the current line is affected, then the last
character to be changed away is marked with a $. A
count causes that many objects to be affected, thus both
3c) and c3) change the following three
sentences (7.4).







d
An operator which deletes the following object. If more than
part of a line is affected, the text is saved in the numeric
buffers. A count causes that many objects to be affected;
thus 3dw is the same as d3w (3.3, 3.4, 4.1,
7.4).







e
Advances to the end of the next word, defined as for
b and w. A count repeats the effect (2.4,
3.1).







f
Finds the first instance of the next character following the
cursor on the current line. A count repeats the find
(4.1).







g
Unused.







Arrow keys h, j, k, l, and
H.







h
Left arrow. Moves the cursor one character to the
left. Like the other arrow keys, either h, the
left arrow key, or one of the synonyms (^H)
has the same effect. On v2 editors, arrow keys on certain
kinds of terminals (those which send escape sequences, such
as vt52, c100, or hp) cannot be used. A count repeats the
effect (3.1, 7.5).







i
Inserts text before the cursor, otherwise like a
(7.2).







j
Down arrow. Moves the cursor one line down in the
same column. If the position does not exist, vi comes
as close as possible to the same column. Synonyms include
^J (linefeed) and ^N.







k
Up arrow. Moves the cursor one line up. ^P is
a synonym.







l
Right arrow. Moves the cursor one character to the
right. SPACE is a synonym.







m
Marks the current position of the cursor in the mark
register which is specified by the next character
a-z. Return to this position or use with an
operator using  or  (5.3).







n
Repeats the last / or ? scanning commands
(2.2).







o
Opens new lines below the current line; otherwise like
O (3.1).







p
Puts text after/below the cursor; otherwise like P
(6.3).







q
Unused.







r
Replaces the single character at the cursor with a single
character you type. The new character may be a
RETURN ; this is the easiest way to split
lines. A count replaces each of the following count
characters with the single character given; see R
above which is the more usually useful iteration of r
(3.2).







s
Changes the single character under the cursor to the text
which follows up to an ESC ; given a count,
that many characters from the current line are changed. The
last character to be changed is marked with $ as in
c (3.2).







t
Advances the cursor upto the character before the next
character typed. Most useful with operators such as d
and c to delete the characters up to a following
character. You can use . to delete more if this
doesn't delete enough the first time (4.1).







u
Undoes the last change made to the current buffer. If
repeated, will alternate between these two states, thus is
its own inverse. When used after an insert which inserted
text on more than one line, the lines are saved in the
numeric named buffers (3.5).







v
Unused.







w
Advances to the beginning of the next word, as defined by
b (2.4).







x
Deletes the single character under the cursor. With a count
deletes deletes that many characters forward from the cursor
position, but only on the current line (6.5).







y
An operator, yanks the following object into the unnamed
temporary buffer. If preceded by a named buffer
specification, "x, the text is placed in
that buffer also. Text can be recovered by a later p
or P (7.4).







z
Redraws the screen with the current line placed as specified
by the following character: RETURN specifies
the top of the screen, . the center of the screen,
and - at the bottom of the screen. A count may be
given after the z and before the following character
to specify the new screen size for the redraw. A count
before the z gives the number of the line to place in
the center of the screen instead of the default current
line. (5.4)







{
Retreats to the beginning of the beginning of the preceding
paragraph. A paragraph begins at each macro in the
paragraphs option, normally `.IP', `.LP', `.PP',
`.QP' and `.bp'. A paragraph also begins after a completely
empty line, and at each section boundary (see [[
above) (4.2, 6.8, 7.6).







|
Places the cursor on the character in the column specified
by the count (7.1, 7.2).







}
Advances to the beginning of the next paragraph. See
{ for the definition of paragraph (4.2, 6.8,
7.6).







~
Unused.







^? ( DEL )
Interrupts the editor, returning it to command accepting
state (1.5, 7.5)

1. Author's Disclaimer



This document does not claim to be 100% complete. There
are a few commands listed in the original document that I
was unable to test either because I do not speak
lisp, because they required programs we don't have,
or because I wasn't able to make them work. In these cases I
left the command out. The commands listed in this document
have been tried and are known to work. It is expected that
prospective users of this document will read it once to get
the flavor of everything that vi can do and then use
it as a reference document. Experimentation is recommended.
If you don't understand a command, try it and see what
happens.



[Note: In revising this document, I have attempted to
make it completely reflect version 2.12 of vi. It
does not attempt to document the VAX version (version 3),
but with one or two exceptions (wrapmargin, arrow keys)
everything said about 2.12 should apply to 3.1. Mark
Horton]



2. Notation



[option] is used to denote optional parts of a
command. Many vi commands have an optional count.
[cnt] means that an optional number may precede the
command to multiply or iterate the command. {variable
item} is used to denote parts of the command which must
appear, but can take a number of different values.
<character [-character]> means that the
character or one of the characters in the range described
between the two angle brackets is to be typed. For example
<esc> means the escape key is to be
typed. <a-z> means that a lower case letter is
to be typed. ^<character> means that the
character is to be typed as a control character, that
is, with the <cntl> key held down while
simultaneously typing the specified character. In this
document control characters will be denoted using the
upper case character, but ^<uppercase chr> and
^<lowercase chr> are equivalent. That is, for example,
<^D> is equal to <^d>. The most
common character abbreviations used in this list are as
follows:






<esc>
escape, octal 033







<cr>
carriage return, ^M, octal 015







<lf>
linefeed ^J, octal 012







<nl>
newline, ^J, octal 012 (same as linefeed)







<bs>
backspace, ^H, octal 010







<tab>
tab, ^I, octal 011







<bell>
bell, ^G, octal 07







<ff>
formfeed, ^L, octal 014







<sp>
space, octal 040







<del>
delete, octal 0177



3. Basics



To run vi the shell variable TERM must be
defined and exported to your environment. How you do this
depends on which shell you are using. You can tell which
shell you have by the character it prompts you for commands
with. The Bourne shell prompts with `$', and the C shell
prompts with `%'. For these examples, we will suppose that
you are using an HP 2621 terminal, whose termcap name is
``2621''.



3.1. Bourne Shell



To manually set your terminal type to 2621 you would
type:


     TERM=2621
     export TERM




There are various ways of having this automatically or
semi-automatically done when you log in. Suppose you usually
dial in on a 2621. You want to tell this to the machine, but
still have it work when you use a hardwired terminal. The
recommended way, if you have the tset program, is to
use the sequence


     tset -s -d 2621 > tset$$
     . tset$$
     rm tset$$




in your .login (for csh) or the same thing using `.'
instead of `source' in your .profile (for sh). The above
line says that if you are dialing in you are on a 2621, but
if you are on a hardwired terminal it figures out your
terminal type from an on-line list.



3.2. The C Shell



To manually set your terminal type to 2621 you would
type:


     setenv TERM 2621




There are various ways of having this automatically or
semi-automatically done when you log in. Suppose you usually
dial in on a 2621. You want to tell this to the machine, but
still have it work when you use a hardwired terminal. The
recommended way, if you have the tset program, is to
use the sequence


     tset -s -d 2621 > tset$$
     source tset$$
     rm tset$$




in your .login.*






The above line says that if you are dialing in you are
on a 2621, but if you are on a hardwired terminal it figures
out your terminal type from an on-line list.



4. Normal Commands



Vi is a visual editor with a window on the file.
What you see on the screen is vi's current notion of
what your file will contain, (at this point in the file),
when it is written out. Most commands do not cause any
change in the screen until the complete command is typed.
Should you get confused while typing a command, you can
abort the command by typing an <del> character. You
will know you are back to command level when you hear a
<bell>. Usually typing an <esc> will produce the
same result. When vi gets an improperly formatted
command it rings the <bell>. Following are the
vi commands broken down by function.



4.1. Entry and Exit



To enter vi on a particular file, type


     vi file




The file will be read in and the cursor will be placed
at the beginning of the first line. The first screenfull of
the file will be displayed on the terminal.



To get out of the editor, type


     ZZ




If you are in some special mode, such as input mode or
the middle of a multi-keystroke command, it may be necessary
to type <esc> first.



4.2. Cursor and Page Motion



NOTE: The arrow keys (see the next four commands)
on certain kinds of terminals will not work with the PDP-11
version of vi. The control versions or the hjkl versions
will work on any terminal. Experienced users prefer the hjkl
keys because they are always right under their fingers.
Beginners often prefer the arrow keys, since they do not
require memorization of which hjkl key is which. The
mnemonic value of hjkl is clear from looking at the keyboard
of an adm3a.



[cnt]<bs> or [cnt]h or
[cnt]




Move the cursor to the left one character. Cursor stops at
the left margin of the page. If cnt is given, these commands
move that many spaces.





[cnt]^N or [cnt]j or [cnt] or
[cnt]<lf>




Move down one line. Moving off the screen scrolls the window
to force a new line onto the screen. Mnemonic:
Next





[cnt]^P or [cnt]k or
[cnt]




Move up one line. Moving off the top of the screen forces
new text onto the screen. Mnemonic:
Previous





[cnt]<sp> or [cnt]l or
[cnt]




Move to the right one character. Cursor will not go beyond
the end of the line.








[cnt]-
Move the cursor up the screen to the beginning of the next line. Scroll if necessary.



[cnt]+ or [cnt]<cr>






Move the cursor down the screen to the beginning of the next line. Scroll up if necessary.







[cnt]$
Move the cursor to the end of the line. If there is a count,
move to the end of the line "cnt" lines forward in
the file.







^
Move the cursor to the beginning of the first word on the
line.







0
Move the cursor to the left margin of the current
line.







[cnt]|
Move the cursor to the column specified by the count. The
default is column zero.







[cnt]w
Move the cursor to the beginning of the next word. If there
is a count, then move forward that many words and position
the cursor at the beginning of the word. Mnemonic:
next-word







[cnt]W
Move the cursor to the beginning of the next word which
follows a "white space" (<sp>,<tab>,
or <nl>). Ignore other punctuation.







[cnt]b
Move the cursor to the preceding word. Mnemonic:
backup-word







[cnt]B
Move the cursor to the preceding word that is separated from
the current word by a "white space"
(<sp>,<tab>, or <nl>).







[cnt]e
Move the cursor to the end of the current word or the end of
the "cnt"'th word hence. Mnemonic:
end-of-word







[cnt]E
Move the cursor to the end of the current word which is
delimited by "white space"
(<sp>,<tab>, or <nl>).







[line number]G
Move the cursor to the line specified. Of particular use are
the sequences "1G" and "G", which move
the cursor to the beginning and the end of the file
respectively. Mnemonic: Go-to



NOTE: The next four commands (^D, ^U, ^F, ^B) are
not true motion commands, in that they cannot be used as the
object of commands such as delete or change.






[cnt]^D
Move the cursor down in the file by "cnt" lines (or the last "cnt" if a new count isn't given. The initial default is half a page.) The screen is simultaneously scrolled up. Mnemonic: Down







[cnt]^U
Move the cursor up in the file by "cnt" lines. The
screen is simultaneously scrolled down. Mnemonic:
Up







[cnt]^F
Move the cursor to the next page. A count moves that many
pages. Two lines of the previous page are kept on the screen
for continuity if possible. Mnemonic:
Forward-a-page







[cnt]^B
Move the cursor to the previous page. Two lines of the
current page are kept if possible. Mnemonic:
Backup-a-page







[cnt](
Move the cursor to the beginning of the next sentence. A
sentence is defined as ending with a ".",
"!", or "?" followed by two spaces or a
<nl>.







[cnt])
Move the cursor backwards to the beginning of a
sentence.







[cnt]}
Move the cursor to the beginning of the next paragraph. This
command works best inside nroff documents. It
understands two sets of nroff macros, -ms and
-mm, for which the commands ".IP",
".LP", ".PP", ".QP",
"P", as well as the nroff command ".bp"
are considered to be paragraph delimiters. A blank line also
delimits a paragraph. The nroff macros that it
accepts as paragraph delimiters is adjustable. See
paragraphs under the Set Commands
section.







[cnt]{
Move the cursor backwards to the beginning of a
paragraph.







]]
Move the cursor to the next "section", where a
section is defined by two sets of nroff macros,
-ms and -mm, in which ".NH",
".SH", and ".H" delimit a section. A
line beginning with a <ff><nl> sequence, or a
line beginning with a "{" are also considered to
be section delimiters. The last option makes it useful for
finding the beginnings of C functions. The nroff
macros that are used for section delimiters can be adjusted.
See sections under the Set Commands
section.







[[
Move the cursor backwards to the beginning of a
section.







%
Move the cursor to the matching parenthesis or brace. This
is very useful in C or lisp code. If the cursor is sitting
on a ( ) { or } the cursor is moved to the
matching character at the other end of the section. If the
cursor is not sitting on a brace or a parenthesis, vi
searches forward until it finds one and then jumps to the
match mate.







[cnt]H
If there is no count move the cursor to the top left
position on the screen. If there is a count, then move the
cursor to the beginning of the line "cnt" lines
from the top of the screen. Mnemonic:
Home







[cnt]L
If there is no count move the cursor to the beginning of the
last line on the screen. If there is a count, then move the
cursor to the beginning of the line "cnt" lines
from the bottom of the screen. Mnemonic:
Last







M
Move the cursor to the beginning of the middle line on the
screen. Mnemonic: Middle







m<a-z>
This command does not move the cursor, but it marks
the place in the file and the character
"<a-z>" becomes the label for referring to
this location in the file. See the next two commands.
Mnemonic: mark NOTE: The mark command is not a
motion, and cannot be used as the target of commands such as
delete.







<a-z>
Move the cursor to the beginning of the line that is marked
with the label "<a-z>".







<a-z>
Move the cursor to the exact position on the line that was
marked with with the label
"<a-z>".







Move the cursor back to the beginning of the line where it
was before the last "non-relative" move. A
"non-relative" move is something such as a search
or a jump to a specific line in the file, rather than moving
the cursor or scrolling the screen.







Move the cursor back to the exact spot on the line where it
was located before the last "non-relative"
move.



4.3. Searches



The following commands allow you to search for items in
a file.






[cnt]f{chr}
Search forward on the line for the next or "cnt"'th occurrence of the character "chr". The cursor is placed at the character of interest. Mnemonic: find character







[cnt]F{chr}
Search backwards on the line for the next or
"cnt"'th occurrence of the character
"chr". The cursor is placed at the
character of interest.







[cnt]t{chr}
Search forward on the line for the next or
"cnt"'th occurrence of the character
"chr". The cursor is placed just preceding
the character of interest. Mnemonic: move cursor up
to character







[cnt]T{chr}
Search backwards on the line for the next or
"cnt"'th occurrence of the character
"chr". The cursor is placed just preceding
the character of interest.







[cnt];
Repeat the last "f", "F", "t"
or "T" command.







[cnt],
Repeat the last "f", "F", "t"
or "T" command, but in the opposite search
direction. This is useful if you overshoot.




[cnt]/[string]/<nl>




Search forward for the next occurrence of
"string". Wrap around at the end of the file does
occur. The final </> is not
required.






[cnt]?[string]?<nl>




Search backwards for the next occurrence of
"string". If a count is specified, the count
becomes the new window size. Wrap around at the beginning of
the file does occur. The final <?> is not
required.








n
Repeat the last /[string]/ or ?[string]? search. Mnemonic: next occurrence.







N
Repeat the last /[string]/ or ?[string]? search, but in the
reverse direction.



:g/[string]/[editor command]<nl>






Using the : syntax it is possible to do global searches ala the standard UNIX "ed" editor.



4.4. Text Insertion



The following commands allow for the insertion of text.
All multicharacter text insertions are terminated with an
<esc> character. The last change can always be
undone by typing a u. The text insert in
insertion mode can contain newlines.






a{text}<esc>
Insert text immediately following the cursor position. Mnemonic: append







A{text}<esc>
Insert text at the end of the current line. Mnemonic:
Append







i{text}<esc>
Insert text immediately preceding the cursor position.
Mnemonic: insert







I{text}<esc>
Insert text at the beginning of the current
line.







o{text}<esc>
Insert a new line after the line on which the cursor appears
and insert text there. Mnemonic: open new
line







O{text}<esc>
Insert a new line preceding the line on which the cursor
appears and insert text there.



4.5. Text Deletion



The following commands allow the user to delete text in
various ways. All changes can always be undone by
typing the u command.






[cnt]x
Delete the character or characters starting at the cursor position.







[cnt]X
Delete the character or characters starting at the character
preceding the cursor position.







D
Deletes the remainder of the line starting at the cursor.
Mnemonic: Delete the rest of line







[cnt]d{motion}
Deletes one or more occurrences of the specified motion. Any
motion from sections 4.1 and 4.2 can be used here. The d can
be stuttered (e.g. [cnt]dd) to delete cnt
lines.



4.6. Text Replacement



The following commands allow the user to simultaneously
delete and insert new text. All such actions can be
undone by typing u following the command.






r<chr>
Replaces the character at the current cursor position with <chr>. This is a one character replacement. No <esc> is required for termination. Mnemonic: replace character







R{text}<esc>
Starts overlaying the characters on the screen with whatever
you type. It does not stop until an <esc> is
typed.




[cnt]s{text}<esc>




Substitute for "cnt" characters beginning at the
current cursor position. A "$" will appear at the
position in the text where the "cnt"'th character
appears so you will know how much you are erasing. Mnemonic:
substitute






[cnt]S{text}<esc>




Substitute for the entire current line (or lines). If no
count is given, a "$" appears at the end of the
current line. If a count of more than 1 is given, all the
lines to be replaced are deleted before the insertion
begins.






[cnt]c{motion}{text}<esc>




Change the specified "motion" by replacing it with
the insertion text. A "$" will appear at the end
of the last item that is being deleted unless the deletion
involves whole lines. Motion's can be any motion from
sections 4.1 or 4.2. Stuttering the c (e.g. [cnt]cc) changes
cnt lines.





4.7. Moving Text



Vi provides a number of ways of moving chunks of
text around. There are nine buffers into which each piece of
text which is deleted or "yanked" is put in
addition to the "undo" buffer. The most recent
deletion or yank is in the "undo" buffer and also
usually in buffer 1, the next most recent in buffer 2, and
so forth. Each new deletion pushes down all the older
deletions. Deletions older than 9 disappear. There is also a
set of named registers, a-z, into which text can optionally
be placed. If any delete or replacement type command is
preceded by "<a-z>, that named buffer will
contain the text deleted after the command is executed. For
example, "a3dd will delete three lines starting
at the current line and put them in buffer
"a.*






There are two more basic commands and some variations
useful in getting and putting text into a file.



["<a-z>][cnt]y{motion}






Yank the specified item or "cnt" items and put in the "undo" buffer or the specified buffer. The variety of "items" that can be yanked is the same as those that can be deleted with the "d" command or changed with the "c" command. In the same way that "dd" means delete the current line and "cc" means replace the current line, "yy" means yank the current line.







["<a-z>][cnt]Y
Yank the current line or the "cnt" lines starting
from the current line. If no buffer is specified, they will
go into the "undo" buffer, like any delete would.
It is equivalent to "yy". Mnemonic:
Yank







["<a-z>]p
Put "undo" buffer or the specified buffer down
after the cursor. If whole lines were yanked or
deleted into the buffer, then they will be put down on the
line following the line the cursor is on. If something else
was deleted, like a word or sentence, then it will be
inserted immediately following the cursor. Mnemonic:
put buffer







It should be noted that text in the named buffers remains
there when you start editing a new file with the :e
file<esc> command. Since this is so, it is
possible to copy or delete text from one file and carry it
over to another file in the buffers. However, the undo
buffer and the ability to undo are lost when changing
files.







["<a-z>]P
Put "undo" buffer or the specified buffer down
before the cursor. If whole lines where yanked or
deleted into the buffer, then they will be put down on the
line preceding the line the cursor is on. If something else
was deleted, like a word or sentence, then it will be
inserted immediately preceding the cursor.







[cnt]>{motion}
The shift operator will right shift all the text from the
line on which the cursor is located to the line where the
motion is located. The text is shifted by one
shiftwidth. (See section 6.) >> means
right shift the current line or lines.







[cnt]<{motion}
The shift operator will left shift all the text from the
line on which the cursor is located to the line where the
item is located. The text is shifted by one
shiftwidth. (See section 6.) << means
left shift the current line or lines. Once the line has
reached the left margin it is not further
affected.







[cnt]={motion}
Prettyprints the indicated area according to lisp
conventions. The area should be a lisp
s-expression.



4.8. Miscellaneous Commands



Vi has a number of miscellaneous commands that
are very useful. They are:






ZZ
This is the normal way to exit from vi. If any changes have been made, the file is written out. Then you are returned to the shell.







^L
Redraw the current screen. This is useful if someone
"write"s you while you are in "vi" or if
for any reason garbage gets onto the screen.







^R
On dumb terminals, those not having the "delete
line" function (the vt100 is such a terminal),
vi saves redrawing the screen when you delete a line
by just marking the line with an "@" at the
beginning and blanking the line. If you want to actually get
rid of the lines marked with "@" and see what the
page looks like, typing a ^R will do this.







.
"Dot" is a particularly useful command. It repeats
the last text modifying command. Therefore you can type a
command once and then to another place and repeat it by just
typing ".".







u
Perhaps the most important command in the editor, u undoes
the last command that changed the buffer. Mnemonic:
undo







U
Undo all the text modifying commands performed on the
current line since the last time you moved onto
it.







[cnt]J
Join the current line and the following line. The <nl>
is deleted and the two lines joined, usually with a space
between the end of the first line and the beginning of what
was the second line. If the first line ended with a
"period", then two spaces are inserted. A count
joins the next cnt lines. Mnemonic: Join
lines







Q
Switch to ex editing mode. In this mode vi
will behave very much like ed. The editor in this
mode will operate on single lines normally and will not
attempt to keep the "window" up to date. Once in
this mode it is also possible to switch to the open
mode of editing. By entering the command [line
number]open<nl> you enter this mode. It is similar
to the normal visual mode except the window is only
one line long. Mnemonic: Quit visual
mode







^]
An abbreviation for a tag command. The cursor should be
positioned at the beginning of a word. That word is taken as
a tag name, and the tag with that name is found as if it had
been typed in a :tag command.



[cnt]!{motion}{UNIX
cmd}<nl>




Any UNIX filter (e.g. command that reads the standard input
and outputs something to the standard output) can be sent a
section of the current file and have the output of the
command replace the original text. Useful examples are
programs like cb, sort, and nroff. For
instance, using sort it would be possible to sort a
section of the current file into a new list. Using !!
means take a line or lines starting at the line the cursor
is currently on and pass them to the UNIX command.
NOTE: To just escape to the shell for one command,
use :!{cmd}<nl>, see section 5.








z{cnt}<nl>
This resets the current window size to "cnt" lines and redraws the screen.



4.9. Special Insert Characters



There are some characters that have special meanings
during insert modes. They are:






^V
During inserts, typing a ^V allows you to quote control characters into the file. Any character typed after the ^V will be inserted into the file.







[^]^D or [0]^D
<^D> without any argument backs up one
shiftwidth. This is necessary to remove indentation
that was inserted by the autoindent feature.
^<^D> temporarily removes all the autoindentation,
thus placing the cursor at the left margin. On the next
line, the previous indent level will be restored. This is
useful for putting "labels" at the left margin.
0<^D> says remove all autoindents and stay that way.
Thus the cursor moves to the left margin and stays there on
successive lines until <tab>'s are typed. As with the
<tab>, the <^D> is only effective before any
other "non-autoindent" controlling characters are
typed. Mnemonic: Delete a shiftwidth







^W
If the cursor is sitting on a word, <^W> moves the
cursor back to the beginning of the word, thus erasing the
word from the insert. Mnemonic: erase
Word







<bs>
The backspace always serves as an erase during insert modes
in addition to your normal "erase" character. To
insert a <bs> into your file, use the <^V> to
quote it.



5. : Commands



Typing a ":" during command mode causes
vi to put the cursor at the bottom on the screen in
preparation for a command. In the ":" mode,
vi can be given most ed commands. It is also
from this mode that you exit from vi or switch to
different files. All commands of this variety are terminated
by a <nl>, <cr>, or <esc>.






:w[!] [file]
Causes vi to write out the current text to the disk. It is written to the file you are editing unless "file" is supplied. If "file" is supplied, the write is directed to that file instead. If that file already exists, vi will not perform the write unless the "!" is supplied indicating you really want to destroy the older copy of the file.







:q[!]
Causes vi to exit. If you have modified the file you
are looking at currently and haven't written it out,
vi will refuse to exit unless the "!" is
supplied.



:e[!] [+[cmd]] [file]






Start editing a new file called "file" or start editing the current file over again. The command ":e!" says "ignore the changes I've made to this file and start over from the beginning". It is useful if you really mess up the file. The optional "+" says instead of starting at the beginning, start at the "end", or, if "cmd" is supplied, execute "cmd" first. Useful cases of this are where cmd is "n" (any integer) which starts at line number n, and "/text", which searches for "text" and starts at the line where it is found.







^^
Switch back to the place you were before your last tag
command. If your last tag command stayed within the file, ^^
returns to that tag. If you have no recent tag command, it
will return to the same place in the previous file that it
was showing when you switched to the current
file.







:n[!]
Start editing the next file in the argument list. Since
vi can be called with multiple file names, the
":n" command tells it to stop work on the current
file and switch to the next file. If the current file was
modifies, it has to be written out before the ":n"
will work or else the "!" must be supplied, which
says discard the changes I made to the current
file.



:n[!] file [file file ...]






Replace the current argument list with a new list of files and start editing the first file in this new list.







:r file
Read in a copy of "file" on the line after the
cursor.







:r !cmd
Execute the "cmd" and take its output and put it
into the file after the current line.







:!cmd
Execute any UNIX shell command.







:ta[!] tag
Vi looks in the file named tags in the current
directory. Tags is a file of lines in the
format:







tag filename vi-search-command







If vi finds the tag you specified in the :ta
command, it stops editing the current file if necessary and
if the current file is up to date on the disk and switches
to the file specified and uses the search pattern specified
to find the "tagged" item of interest. This is
particularly useful when editing multi-file C programs such
as the operating system. There is a program called
ctags which will generate an appropriate tags
file for C and f77 programs so that by saying :ta
function<nl> you will be switched to that
function. It could also be useful when editing multi-file
documents, though the tags file would have to be
generated manually.



6. Special Arrangements for Startup



Vi takes the value of $TERM and looks up
the characteristics of that terminal in the file
/etc/termcap. If you don't know vi's name for
the terminal you are working on, look in
/etc/termcap.



When vi starts, it attempts to read the variable
EXINIT from your environment.* If that exists, it takes the
values in it as the default values for certain of its
internal constants. See the section on "Set
Values" for further details. If EXINIT doesn't exist
you will get all the normal defaults.






Should you inadvertently hang up the phone while inside
vi, or should the computer crash, all may not be
lost. Upon returning to the system, type:


     vi -r file




This will normally recover the file. If there is more
than one temporary file for a specific file name, vi
recovers the newest one. You can get an older version by
recovering the file more than once. The command "vi
-r" without a file name gives you the list of files
that were saved in the last system crash (but not the
file just saved when the phone was hung up).



7. Set Commands



Vi has a number of internal variables and
switches which can be set to achieve special affects. These
options come in three forms, those that are switches, which
toggle from off to on and back, those that require a numeric
value, and those that require an alphanumeric string value.
The toggle options are set by a command of the form:


     :set option<nl>




and turned off with the command:


     :set nooption<nl>




Commands requiring a value are set with a command of the
form:


     :set option=value<nl>




To display the value of a specific option type:


     :set option?<nl>




To display only those that you have changed type:


     :set<nl>




and to display the long table of all the settable
parameters and their current values type:


     :set all<nl>




Most of the options have a long form and an
abbreviation. Both are listed in the following table as well
as the normal default value.



To arrange to have values other than the default used
every time you enter vi, place the appropriate
set command in EXINIT in your environment, e.g.


     EXINIT='set ai aw terse sh=/bin/csh'
     export EXINIT




or


     setenv EXINIT 'set ai aw terse sh=/bin/csh'




for sh and csh, respectively. These are
usually placed in your .profile or .login. If you are
running a system without environments (such as version 6)
you can place the set command in the file .exrc in your home
directory.






autoindent ai
Default: noai Type: toggle

When in autoindent mode, vi helps you indent code by starting each line in the same column as the preceding line. Tabbing to the right with <tab> or <^T> will move this boundary to the right, and it can be moved to the left with <^D>.







autoprint ap
Default: ap Type: toggle

Causes the current line to be printed after each ex text
modifying command. This is not of much interest in the
normal vi visual mode.







autowrite aw
Default: noaw type: toggle

Autowrite causes an automatic write to be done if there are
unsaved changes before certain commands which change files
or otherwise interact with the outside world. These commands
are :!, :tag, :next, :rewind, ^^, and ^].







beautify bf
Default: nobf Type: toggle

Causes all control characters except <tab>,
<nl>, and <ff> to be discarded.







directory dir
Default: dir=/tmp Type: string

This is the directory in which vi puts its temporary
file.







errorbells eb
Default: noeb Type: toggle

Error messages are preceded by a <bell>.







hardtabs ht
Default: hardtabs=8 Type: numeric

This option contains the value of hardware tabs in your
terminal, or of software tabs expanded by the Unix
system.







ignorecase ic
Default: noic Type: toggle

All upper case characters are mapped to lower case in
regular expression matching.







lisp
Default: nolisp Type: toggle

Autoindent for lisp code. The commands ( ) [[
and ]] are modified appropriately to affect
s-expressions and functions.







list
Default: nolist Type: toggle

All printed lines have the <tab> and <nl>
characters displayed visually.







magic
Default: magic Type: toggle

Enable the metacharacters for matching. These include . *
< > [string] [^string] and
[<chr>-<chr>].







number nu
Default: nonu Type: toggle

Each line is displayed with its line number.







open
Default: open Type: toggle

When set, prevents entering open or visual modes from ex or
edit. Not of interest from vi.







optimize opt
Default: opt Type: toggle

Basically of use only when using the ex capabilities.
This option prevents automatic <cr>s from taking
place, and speeds up output of indented lines, at the
expense of losing typeahead on some versions of
UNIX.







paragraphs para
Default: para=IPLPPPQPP bp Type: string

Each pair of characters in the string indicate nroff
macros which are to be treated as the beginning of a
paragraph for the { and } commands. The
default string is for the -ms and -mm macros.
To indicate one letter nroff macros, such as
.P or .H, quote a space in for the second
character position. For example:







:set paragraphs=P\ bp<nl>







would cause vi to consider .P and .bp
as paragraph delimiters.







prompt
Default: prompt Type: toggle

In ex command mode the prompt character : will
be printed when ex is waiting for a command. This is
not of interest from vi.







redraw
Default: noredraw Type: toggle

On dumb terminals, force the screen to always be up to date,
by sending great amounts of output. Useful only at high
speeds.







report
Default: report=5 Type: numeric

This sets the threshold for the number of lines modified.
When more than this number of lines are modified, removed,
or yanked, vi will report the number of lines changed
at the bottom of the screen.







scroll
Default: scroll={1/2 window} Type: numeric

This is the number of lines that the screen scrolls up or
down when using the <^U> and <^D>
commands.







sections
Default: sections=SHNHH HU Type: string

Each two character pair of this string specify nroff
macro names which are to be treated as the beginning of a
section by the ]] and [[ commands. The default
string is for the -ms and -mm macros. To enter
one letter nroff macros, use a quoted space as the
second character. See paragraphs for a fuller
explanation.







shell sh
Default: sh=from environment SHELL or /bin/sh Type:
string

This is the name of the sh to be used for
"escaped" commands.







shiftwidth sw
Default: sw=8 Type: numeric

This is the number of spaces that a <^T> or <^D>
will move over for indenting, and the amount < and >
shift by.







showmatch sm
Default: nosm Type: toggle

When a ) or } is typed, show the matching
( or { by moving the cursor to it for one
second if it is on the current screen.







slowopen slow
Default: terminal dependent Type: toggle

On terminals that are slow and unintelligent, this option
prevents the updating of the screen some of the time to
improve speed.







tabstop ts
Default: ts=8 Type: numeric

<tab>s are expanded to boundaries that are multiples
of this value.







taglength tl
Default: tl=0 Type: numeric

If nonzero, tag names are only significant to this many
characters.







term
Default: (from environment TERM, else dumb) Type:
string

This is the terminal and controls the visual displays. It
cannot be changed when in "visual" mode, you have
to Q to command mode, type a set term command, and do
``vi.'' to get back into visual. Or exit vi, fix $TERM, and
reenter. The definitions that drive a particular terminal
type are found in the file /etc/termcap.







terse
Default: terse Type: toggle

When set, the error diagnostics are short.







warn
Default: warn Type: toggle

The user is warned if she/he tries to escape to the shell
without writing out the current changes.







window
Default: window={8 at 600 baud or less, 16 at 1200 baud, and
screen size - 1 at 2400 baud or more} Type: numeric

This is the number of lines in the window whenever vi
must redraw an entire screen. It is useful to make this size
smaller if you are on a slow line.



w300, w1200,
w9600




These set window, but only within the corresponding speed
ranges. They are useful in an EXINIT to fine tune window
sizes. For example,









     set w300=4 w1200=12

causes a 4 lines window at speed up to 600 baud, a 12 line window at 1200 baud, and a full screen (the default) at over 1200 baud.







wrapscan ws
Default: ws Type: toggle

Searches will wrap around the end of the file when is option
is set. When it is off, the search will terminate when it
reaches the end or the beginning of the file.







wrapmargin wm
Default: wm=0 Type: numeric

Vi will automatically insert a <nl> when it finds
a natural break point (usually a <sp> between words)
that occurs within "wm" spaces of the right
margin. Therefore with "wm=0" the option is off.
Setting it to 10 would mean that any time you are within 10
spaces of the right margin vi would be looking for a
<sp> or <tab> which it could replace with a
<nl>. This is convenient for people who forget to look
at the screen while they type. (In version 3, wrapmargin
behaves more like nroff, in that the boundary specified by
the distance from the right edge of the screen is taken as
the rightmost edge of the area where a break is allowed,
instead of the leftmost edge.)







writeany wa
Default: nowa Type: toggle

Vi normally makes a number of checks before it writes
out a file. This prevents the user from inadvertently
destroying a file. When the "writeany" option is
enabled, vi no longer makes these
checks.

 * exrc_isok --

 * Historically, vi read the $HOME and local .exrc files if they were owned
 * by the user's real ID, or the "sourceany" option was set, regardless of
 * any other considerations.  We no longer support the sourceany option as
 * it's a security problem of mammoth proportions.  We require the system
 * .exrc file to be owned by root, the $HOME .exrc file to be owned by the
 * user's effective ID (or that the user's effective ID be root) and the
 * local .exrc files to be owned by the user's effective ID.  In all cases,
 * the file cannot be writeable by anyone other than its owner.
 *
 * In O'Reilly ("Learning the VI Editor", Fifth Ed., May 1992, page 106),
 * it notes that System V release 3.2 and later has an option "[no]exrc".
 * The behavior is that local .exrc files are read only if the exrc option
 * is set.  The default for the exrc option was off, so, by default, local
 * .exrc files were not read.  The problem this was intended to solve was
 * that System V permitted users to give away files, so there's no possible
 * ownership or writeability test to ensure that the file is safe.
 *
 * POSIX 1003.2-1992 standardized exrc as an option.  It required the exrc
 * option to be off by default, thus local .exrc files are not to be read
 * by default.  The Rationale noted (incorrectly) that this was a change
 * to historic practice, but correctly noted that a default of off improves
 * system security.  POSIX also required that vi check the effective user
 * ID instead of the real user ID, which is why we've switched from historic
 * practice.
 *
 * We initialize the exrc variable to off.  If it's turned on by the system
 * or $HOME .exrc files, and the local .exrc file passes the ownership and
 * writeability tests, then we read it.  This breaks historic 4BSD practice,
 * but it gives us a measure of security on systems where users can give away
 * files.

/*
 * This file defines three types of data structures: lists, tail queues,
 * and circular queues.
 *
 * A list is headed by a single forward pointer (or an array of forward
 * pointers for a hash table header). The elements are doubly linked
 * so that an arbitrary element can be removed without a need to
 * traverse the list. New elements can be added to the list before
 * or after an existing element or at the head of the list. A list
 * may only be traversed in the forward direction.
 *
 * A tail queue is headed by a pair of pointers, one to the head of the
 * list and the other to the tail of the list. The elements are doubly
 * linked so that an arbitrary element can be removed without a need to
 * traverse the list. New elements can be added to the list before or
 * after an existing element, at the head of the list, or at the end of
 * the list. A tail queue may only be traversed in the forward direction.
 *
 * A circle queue is headed by a pair of pointers, one to the head of the
 * list and the other to the tail of the list. The elements are doubly
 * linked so that an arbitrary element can be removed without a need to
 * traverse the list. New elements can be added to the list before or after
 * an existing element, at the head of the list, or at the end of the list.
 * A circle queue may be traversed in either direction, but has a more

 *			is due to the exposure events all showing up after
 *			the scrolling is completed (pipe_input_func does all
 *			of the scrolling and then we get back to XtMainLoop)
 *
 *	split		Ought to be able to put a title on each pane
 *			Need protocol messages to shift focus
 *
 *	bell		user settable visible bell
 *
 *	busy		don't understand the protocol
 *
 *	mouse		need to send IPO_MOVE_CARET( row, column )
 *			(note that screen code does not know about tabs or
 *			line wraps)
 *			Connect to window manager cut buffer
 *			need to send IPO_EXTEND_SELECT( r1, c1, r2, c1 )
 *			otherwise core and screen duplicate selection logic
 *			Need to determine correct screen for event.  Not
 *			needed until split is implemented.
 *
 *	arrow keys	need to define a protocol.  I can easily send
 *			the vt100 sequences (and currently do).
 *			In general, we need to define what special keys
 *			do (for example PageUp) and what happens when we
 *			are in Insert mode.
 *
 *			Suggestion: IPO_COMMAND( string ).  vi core can
 *			take it as a command even when in insert mode.
 *
 *	icon		Is currently B&W.  To get a color icon, would
 *			require a lot of work or that bostic pick up
 *			the xpm library.

   StringArray
   ===========
   The type |StringArray| represents an array of |String|s, with the
   proviso that by convention the last member of a |StringArray| is
   always a |NULL| pointer. There is a converter that can construct a
   |StringArray| from a single string.


   cvtStringToStringArray
   ======================
   The converter from |String| to |StringArray| makes a copy of the
   passed string and then replaces all occurences of the delimiter
   with a nul byte. The |StringArray| is filled with pointers to the
   parts of the string.

   The delimiter character is the first character in the string.


   newStringArray
   ==============
   The function |newStringArray| makes a copy of a |StringArray|. It
   allocates new space for the array itself and for the strings that
   it contains.


   freeStringArray
   ===============
   |freeStringArray| deallocates the array and all strings it
   contains. Note that this works for StringArrays produced with
   |newStringArray|, but not for those created by
   |cvtStringToStringArray|!

VI - VI module within perl embedded nvi

=head1 SYNOPSIS

    sub wc {
      my $words;
      $i = $VI::StartLine;
      while ($i <= $VI::StopLine) {
	$_ = $curscr->GetLine($i++);
        $words+=split;
      }
      $curscr->Msg("$words words");
    }

=head1 DESCRIPTION

This pseudo module is available to perl programs run from within nvi and
provides access to the files being edited and some internal data.

Beware that you should not use this module from within a C or
from within an C block or a C method.

=head2 Variables

These are set by nvi before starting each perl command.

=over 8

=item * $curscr

=item * SetLine

    VI::SetLine(screenId,lineNumber,text);

Set lineNumber to the text supplied.

=item * SetMark

    VI::SetMark(screenId,mark,line,column);

Set the mark to the line and column numbers supplied.

=item * SetOpt

    VI::SetOpt(screenId,command);

Set an option.

=item * SwitchScreen

    VI::SwitchScreen(screenId,screenId);

Change the current focus to screen.

=item * TagQ

    $screen->TagQ("tag identification string")

Creates a new tag queue object associated to $screen
to which "tags" can be added.
See further about methods you can use on tag queues.

=item * UnmapKey

    VI::UnmmapKey(screenId,key);

Unmap a key.

=item * Warn

This is the default warning handler.
It adds any warnings to the error string.

=item * Opt

    $screen->Opt;

Returns a tied hash representing the options of the screen.
Note that you can only retrieve and set hash elements.

=item * Map

    $screen->Map;

Returns a tied hash representing the mappings of the screen.
Note that you can only retrieve, set and delete hash elements.

=item * Mark

    $screen->Mark;

Returns a tied hash representing the marks of the screen.

=item * Line

    $screen->Line;

Returns a tied array representing the lines of the screen.

=back

=head2 Tag queue methods

=item * Add

    $tagq->Add($filename, $searchstring, $msg)

Adds a tag to the tag queue. 
The $searchstring argument is (line)number or
a string representing a regular expression.

=item * Push

    $tagq->Push()

Pushes the tag queue onto its associated screen.
The result of the operation is as if the user had enter the
tag command and nvi had found the locations that were added
using the Add method.

For an example, see the make.pl script.

=back

=head1 EXAMPLES

    sub showmarks {
      my ($mark, $all);
      for $mark ('a' .. 'z') {
        eval {VI::GetMark($VI::ScreenId, $mark)};
        $all .= $mark unless ($@);
      }
      VI::Msg($VI::ScreenId,"Set marks: $all");
    }

    sub forall {
      my ($code) = shift;
      my ($i) = $VI::StartLine-1;
      while (++$i <= $VI::StopLine) {
        $_ = VI::GetLine($VI::ScreenId, $i);
        VI::SetLine($VI::ScreenId, $i, $_) if(&$code);
      }
    }

Now you can do

    :perl forall sub{s/perlre/substitution/}

Although you'll probably use

    :perldo s/perlre/substitution/

instead.

See L for perl regular expressions.

nviperl - nvi with embedded perl

=head1 SYNOPSIS

    :perl require 'wc.pl'
    :perl wc
    :,$perldo $_=reverse($_)

=head1 DESCRIPTION

nvi with embedded perl allows you to run perl commands from within nvi.
Two additional commands are made available when you enable the perl
interpreter:

=over 8

=item * perl cmd

The perl command passes the specified commands to the perl interpreter.
The C<$VI::ScreenId>, C<$VI::StartLine> and C<$VI::StopLine> are set.
To find out how to maniplulate the nvi screens, see L.

=item * perldo cmd

The perldo command runs the specified commands on each line of the range
(every line of the file if no range specified).  Before running the
command the line is copied into $_.  If the command returns a true value
the line is replaced by the new value of $_.

The perldo commando does B set the C variables.  (If you think
this is a bad idea, tell me.)

New in alpha3.4:  The complex bug alluded to below has been fixed (in a
slightly kludgey temporary way that may hurt efficiency a bit; this is
another "get it out the door for 4.4" release).  The tests at the end of
the tests file have accordingly been uncommented.  The primary sign of
the bug was that something like a?b matching ab matched b rather than ab.
(The bug was essentially specific to this exact situation, else it would
have shown up earlier.)

New in alpha3.3:  The definition of word boundaries has been altered
slightly, to more closely match the usual programming notion that "_"
is an alphabetic.  Stuff used for pre-ANSI systems is now in a subdir,
and the makefile no longer alludes to it in mysterious ways.  The
makefile has generally been cleaned up some.  Fixes have been made
(again!) so that the regression test will run without -DREDEBUG, at
the cost of weaker checking.  A workaround for a bug in some folks'
 has been added.  And some more things have been added to
tests, including a couple right at the end which are commented out
because the code currently flunks them (complex bug; fix coming).
Plus the usual minor cleanup.

New in alpha3.2:  Assorted bits of cleanup and portability improvement
(the development base is now a BSDI system using GCC instead of an ancient
Sun system, and the newer compiler exposed some glitches).  Fix for a
serious bug that affected REs using many [] (including REG_ICASE REs
because of the way they are implemented), *sometimes*, depending on
memory-allocation patterns.  The header-file prototypes no longer name
the parameters, avoiding possible name conflicts.  The possibility that
some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
now handled gracefully.  "uchar" is no longer used as an internal type
name (too many people have the same idea).  Still the same old lousy
performance, alas.

New in alpha3.1:  Basically nothing, this release is just a bookkeeping
convenience.  Stay tuned.

New in alpha3.0:  Performance is no better, alas, but some fixes have been
made and some functionality has been added.  (This is basically the "get
it out the door in time for 4.4" release.)  One bug fix:  regfree() didn't
free the main internal structure (how embarrassing).  It is now possible
to put NULs in either the RE or the target string, using (resp.) a new
REG_PEND flag and the old REG_STARTEND flag.  The REG_NOSPEC flag to
regcomp() makes all characters ordinary, so you can match a literal
string easily (this will become more useful when performance improves!).
There are now primitives to match beginnings and ends of words, although
the syntax is disgusting and so is the implementation.  The REG_ATOI
debugging interface has changed a bit.  And there has been considerable
internal cleanup of various kinds.

New in alpha2.3:  Split change list out of README, and moved flags notes
into Makefile.  Macro-ized the name of regex(7) in regex(3), since it has
to change for 4.4BSD.  Cleanup work in engine.c, and some new regression
tests to catch tricky cases thereof.

New in alpha2.2:  Out-of-date manpages updated.  Regerror() acquires two
small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
in my own test program and might be useful to others for similar purposes.
The regression test will now compile (and run) without REDEBUG.  The
BRE \$ bug is fixed.  Most uses of "uchar" are gone; it's all chars now.
Char/uchar parameters are now written int/unsigned, to avoid possible
portability problems with unpromoted parameters.  Some unsigned casts have
been introduced to minimize portability problems with shifting into sign
bits.

New in alpha2.1:  Lots of little stuff, cleanup and fixes.  The one big
thing is that regex.h is now generated, using mkh, rather than being
supplied in the distribution; due to circularities in dependencies,
you have to build regex.h explicitly by "make h".  The two known bugs
have been fixed (and the regression test now checks for them), as has a
problem with assertions not being suppressed in the absence of REDEBUG.
No performance work yet.

New in alpha2:  Backslash-anything is an ordinary character, not an
error (except, of course, for the handful of backslashed metacharacters
in BREs), which should reduce script breakage.  The regression test
checks *where* null strings are supposed to match, and has generally
been tightened up somewhat.  Small bug fixes in parameter passing (not
harmful, but technically errors) and some other areas.  Debugging
invoked by defining REDEBUG rather than not defining NDEBUG.

New in alpha+3:  full prototyping for internal routines, using a little
helper program, mkh, which extracts prototypes given in stylized comments.
More minor cleanup.  Buglet fix:  it's CHAR_BIT, not CHAR_BITS.  Simple
pre-screening of input when a literal string is known to be part of the
RE; this does wonders for performance.

New in alpha+2:  minor bits of cleanup.  Notably, the number "32" for the
word width isn't hardwired into regexec.c any more, the public header
file prototypes the functions if __STDC__ is defined, and some small typos
in the manpages have been fixed.

New in alpha+1:  improvements to the manual pages, and an important
extension, the REG_STARTEND option to regexec().

.TH RE_FORMAT 7 "March 16, 1994"
.SH NAME
re_format \- POSIX 1003.2 regular expressions
.SH DESCRIPTION
Regular expressions (``RE''s),
as defined in POSIX 1003.2, come in two forms:
modern REs (roughly those of
.IR egrep ;
1003.2 calls these ``extended'' REs)
and obsolete REs (roughly those of
.IR ed ;
1003.2 ``basic'' REs).
Obsolete REs mostly exist for backward compatibility in some old programs;
they will be discussed at the end.
1003.2 leaves some aspects of RE syntax and semantics open;
`\(dg' marks decisions on these aspects that
may not be fully portable to other 1003.2 implementations.
.PP
A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR,
separated by `|'.
It matches anything that matches one of the branches.
.PP
A branch is one\(dg or more \fIpieces\fR, concatenated.
It matches a match for the first, followed by a match for the second, etc.
.PP
A piece is an \fIatom\fR possibly followed
by a single\(dg `*', `+', `?', or \fIbound\fR.
An atom followed by `*' matches a sequence of 0 or more matches of the atom.
An atom followed by `+' matches a sequence of 1 or more matches of the atom.
An atom followed by `?' matches a sequence of 0 or 1 matches of the atom.
.PP
A \fIbound\fR is `{' followed by an unsigned decimal integer,
possibly followed by `,'
possibly followed by another unsigned decimal integer,
always followed by `}'.
The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive,
and if there are two of them, the first may not exceed the second.
An atom followed by a bound containing one integer \fIi\fR
and no comma matches
a sequence of exactly \fIi\fR matches of the atom.
An atom followed by a bound
containing one integer \fIi\fR and a comma matches
a sequence of \fIi\fR or more matches of the atom.
An atom followed by a bound
containing two integers \fIi\fR and \fIj\fR matches
a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom.
.PP
An atom is a regular expression enclosed in `()' (matching a match for the
regular expression),
an empty set of `()' (matching the null string)\(dg,
a \fIbracket expression\fR (see below), `.'
(matching any single character), `^' (matching the null string at the
beginning of a line), `$' (matching the null string at the
end of a line), a `\e' followed by one of the characters
`^.[$()|*+?{\e'
(matching that character taken as an ordinary character),
a `\e' followed by any other character\(dg
(matching that character taken as an ordinary character,
as if the `\e' had not been present\(dg),
or a single character with no other significance (matching that character).
A `{' followed by a character other than a digit is an ordinary
character, not the beginning of a bound\(dg.
It is illegal to end an RE with `\e'.
.PP
A \fIbracket expression\fR is a list of characters enclosed in `[]'.
It normally matches any single character from the list (but see below).
If the list begins with `^',
it matches any single character
(but see below) \fInot\fR from the rest of the list.
If two characters in the list are separated by `\-', this is shorthand
for the full \fIrange\fR of characters between those two (inclusive) in the
collating sequence,
e.g. `[0-9]' in ASCII matches any decimal digit.
It is illegal\(dg for two ranges to share an
endpoint, e.g. `a-c-e'.
Ranges are very collating-sequence-dependent,
and portable programs should avoid relying on them.
.PP
To include a literal `]' in the list, make it the first character
(following a possible `^').
To include a literal `\-', make it the first or last character,
or the second endpoint of a range.
To use a literal `\-' as the first endpoint of a range,
enclose it in `[.' and `.]' to make it a collating element (see below).
With the exception of these and some combinations using `[' (see next
paragraphs), all other special characters, including `\e', lose their
special significance within a bracket expression.
.PP
Within a bracket expression, a collating element (a character,
a multi-character sequence that collates as if it were a single character,
or a collating-sequence name for either)
enclosed in `[.' and `.]' stands for the
sequence of characters of that collating element.
The sequence is a single element of the bracket expression's list.
A bracket expression containing a multi-character collating element 
can thus match more than one character,
e.g. if the collating sequence includes a `ch' collating element,
then the RE `[[.ch.]]*c' matches the first five characters
of `chchcc'.
.PP
Within a bracket expression, a collating element enclosed in `[=' and
`=]' is an equivalence class, standing for the sequences of characters
of all collating elements equivalent to that one, including itself.
(If there are no other equivalent collating elements,
the treatment is as if the enclosing delimiters were `[.' and `.]'.)
For example, if o and \o'o^' are the members of an equivalence class,
then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous.
An equivalence class may not\(dg be an endpoint
of a range.
.PP
Within a bracket expression, the name of a \fIcharacter class\fR enclosed
in `[:' and `:]' stands for the list of all characters belonging to that
class.
Standard character class names are:
.PP
.RS
.nf
.ta 3c 6c 9c
alnum	digit	punct
alpha	graph	space
blank	lower	upper
cntrl	print	xdigit
.fi
.RE
.PP
These stand for the character classes defined in
.IR ctype (3).
A locale may provide others.
A character class may not be used as an endpoint of a range.
.PP
There are two special cases\(dg of bracket expressions:
the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at
the beginning and end of a word respectively.
A word is defined as a sequence of
word characters
which is neither preceded nor followed by
word characters.
A word character is an
.I alnum
character (as defined by
.IR ctype (3))
or an underscore.
This is an extension,
compatible with but not specified by POSIX 1003.2,
and should be used with
caution in software intended to be portable to other systems.
.PP
In the event that an RE could match more than one substring of a given
string,
the RE matches the one starting earliest in the string.
If the RE could match more than one substring starting at that point,
it matches the longest.
Subexpressions also match the longest possible substrings, subject to
the constraint that the whole match be as long as possible,
with subexpressions starting earlier in the RE taking priority over
ones starting later.
Note that higher-level subexpressions thus take priority over
their lower-level component subexpressions.
.PP
Match lengths are measured in characters, not collating elements.
A null string is considered longer than no match at all.
For example,
`bb*' matches the three middle characters of `abbbc',
`(wee|week)(knights|nights)' matches all ten characters of `weeknights',
when `(.*).*' is matched against `abc' the parenthesized subexpression
matches all three characters, and
when `(a*)*' is matched against `bc' both the whole RE and the parenthesized
subexpression match the null string.
.PP
If case-independent matching is specified,
the effect is much as if all case distinctions had vanished from the
alphabet.
When an alphabetic that exists in multiple cases appears as an
ordinary character outside a bracket expression, it is effectively
transformed into a bracket expression containing both cases,
e.g. `x' becomes `[xX]'.
When it appears inside a bracket expression, all case counterparts
of it are added to the bracket expression, so that (e.g.) `[x]'
becomes `[xX]' and `[^x]' becomes `[^xX]'.
.PP
No particular limit is imposed on the length of REs\(dg.
Programs intended to be portable should not employ REs longer
than 256 bytes,
as an implementation can refuse to accept such REs and remain
POSIX-compliant.
.PP
Obsolete (``basic'') regular expressions differ in several respects.
`|', `+', and `?' are ordinary characters and there is no equivalent
for their functionality.
The delimiters for bounds are `\e{' and `\e}',
with `{' and `}' by themselves ordinary characters.
The parentheses for nested subexpressions are `\e(' and `\e)',
with `(' and `)' by themselves ordinary characters.
`^' is an ordinary character except at the beginning of the
RE or\(dg the beginning of a parenthesized subexpression,
`$' is an ordinary character except at the end of the
RE or\(dg the end of a parenthesized subexpression,
and `*' is an ordinary character if it appears at the beginning of the
RE or the beginning of a parenthesized subexpression
(after a possible leading `^').
Finally, there is one new type of atom, a \fIback reference\fR:
`\e' followed by a non-zero decimal digit \fId\fR
matches the same sequence of characters
matched by the \fId\fRth parenthesized subexpression
(numbering subexpressions by the positions of their opening parentheses,
left to right),
so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'.

POSIX 1003.2, section 2.8 (Regular Expression Notation).
.SH BUGS
Having two kinds of REs is a botch.
.PP
The current 1003.2 spec says that `)' is an ordinary character in
the absence of an unmatched `(';
this was an unintentional result of a wording error,
and change is likely.
Avoid relying on it.
.PP
Back references are a dreadful botch,
posing major problems for efficient implementations.
They are also somewhat vaguely defined
(does
`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?).
Avoid using them.
.PP
1003.2's specification of case-independent matching is vague.
The ``one case implies all cases'' definition given above
is current consensus among implementors as to the right interpretation.
.PP
The syntax for word boundaries is incredibly ugly.

.SH DESCRIPTION
These routines implement POSIX 1003.2 regular expressions (``RE''s);
see
.ZR .
.I Regcomp
compiles an RE written as a string into an internal form,
.I regexec
matches that internal form against a string and reports results,
.I regerror
transforms error codes from either into human-readable messages,
and
.I regfree
frees any dynamically-allocated storage used by the internal form
of an RE.
.PP
The header
.I 
declares two structure types,
.I regex_t
and
.IR regmatch_t ,
the former for compiled internal forms and the latter for match reporting.
It also declares the four functions,
a type
.IR regoff_t ,
and a number of constants with names starting with ``REG_''.
.PP
.I Regcomp
compiles the regular expression contained in the
.I pattern
string,
subject to the flags in
.IR cflags ,
and places the results in the
.I regex_t
structure pointed to by
.IR preg .
.I Cflags
is the bitwise OR of zero or more of the following flags:
.IP REG_EXTENDED \w'REG_EXTENDED'u+2n
Compile modern (``extended'') REs,
rather than the obsolete (``basic'') REs that
are the default.
.IP REG_BASIC
This is a synonym for 0,
provided as a counterpart to REG_EXTENDED to improve readability.
.IP REG_NOSPEC
Compile with recognition of all special characters turned off.
All characters are thus considered ordinary,
so the ``RE'' is a literal string.
This is an extension,
compatible with but not specified by POSIX 1003.2,
and should be used with
caution in software intended to be portable to other systems.
REG_EXTENDED and REG_NOSPEC may not be used
in the same call to
.IR regcomp .
.IP REG_ICASE
Compile for matching that ignores upper/lower case distinctions.
See
.ZR .
.IP REG_NOSUB
Compile for matching that need only report success or failure,
not what was matched.
.IP REG_NEWLINE
Compile for newline-sensitive matching.
By default, newline is a completely ordinary character with no special
meaning in either REs or strings.
With this flag,
`[^' bracket expressions and `.' never match newline,
a `^' anchor matches the null string after any newline in the string
in addition to its normal function,
and the `$' anchor matches the null string before any newline in the
string in addition to its normal function.
.IP REG_PEND
The regular expression ends,
not at the first NUL,
but just before the character pointed to by the
.I re_endp
member of the structure pointed to by
.IR preg .
The
.I re_endp
member is of type
.IR const\ char\ * .
This flag permits inclusion of NULs in the RE;
they are considered ordinary characters.
This is an extension,
compatible with but not specified by POSIX 1003.2,
and should be used with
caution in software intended to be portable to other systems.
.PP
When successful,
.I regcomp
returns 0 and fills in the structure pointed to by
.IR preg .
One member of that structure
(other than
.IR re_endp )
is publicized:
.IR re_nsub ,
of type
.IR size_t ,
contains the number of parenthesized subexpressions within the RE
(except that the value of this member is undefined if the
REG_NOSUB flag was used).
If
.I regcomp
fails, it returns a non-zero error code;
see DIAGNOSTICS.
.PP
.I Regexec
matches the compiled RE pointed to by
.I preg
against the
.IR string ,
subject to the flags in
.IR eflags ,
and reports results using
.IR nmatch ,
.IR pmatch ,
and the returned value.
The RE must have been compiled by a previous invocation of
.IR regcomp .
The compiled form is not altered during execution of
.IR regexec ,
so a single compiled RE can be used simultaneously by multiple threads.
.PP
By default,
the NUL-terminated string pointed to by
.I string
is considered to be the text of an entire line, minus any terminating
newline.
The
.I eflags
argument is the bitwise OR of zero or more of the following flags:
.IP REG_NOTBOL \w'REG_STARTEND'u+2n
The first character of
the string
is not the beginning of a line, so the `^' anchor should not match before it.
This does not affect the behavior of newlines under REG_NEWLINE.
.IP REG_NOTEOL
The NUL terminating
the string
does not end a line, so the `$' anchor should not match before it.
This does not affect the behavior of newlines under REG_NEWLINE.
.IP REG_STARTEND
The string is considered to start at
\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_so\fR
and to have a terminating NUL located at
\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_eo\fR
(there need not actually be a NUL at that location),
regardless of the value of
.IR nmatch .
See below for the definition of
.IR pmatch
and
.IR nmatch .
This is an extension,
compatible with but not specified by POSIX 1003.2,
and should be used with
caution in software intended to be portable to other systems.
Note that a non-zero \fIrm_so\fR does not imply REG_NOTBOL;
REG_STARTEND affects only the location of the string,
not how it is matched.
.PP
See
.ZR
for a discussion of what is matched in situations where an RE or a
portion thereof could match any of several substrings of
.IR string .
.PP
Normally,
.I regexec
returns 0 for success and the non-zero code REG_NOMATCH for failure.
Other non-zero error codes may be returned in exceptional situations;
see DIAGNOSTICS.
.PP
If REG_NOSUB was specified in the compilation of the RE,
or if
.I nmatch
is 0,
.I regexec
ignores the
.I pmatch
argument (but see below for the case where REG_STARTEND is specified).
Otherwise,
.I pmatch
points to an array of
.I nmatch
structures of type
.IR regmatch_t .
Such a structure has at least the members
.I rm_so
and
.IR rm_eo ,
both of type
.I regoff_t
(a signed arithmetic type at least as large as an
.I off_t
and a
.IR ssize_t ),
containing respectively the offset of the first character of a substring
and the offset of the first character after the end of the substring.
Offsets are measured from the beginning of the
.I string
argument given to
.IR regexec .
An empty substring is denoted by equal offsets,
both indicating the character following the empty substring.
.PP
The 0th member of the
.I pmatch
array is filled in to indicate what substring of
.I string
was matched by the entire RE.
Remaining members report what substring was matched by parenthesized
subexpressions within the RE;
member
.I i
reports subexpression
.IR i ,
with subexpressions counted (starting at 1) by the order of their opening
parentheses in the RE, left to right.
Unused entries in the array\(emcorresponding either to subexpressions that
did not participate in the match at all, or to subexpressions that do not
exist in the RE (that is, \fIi\fR\ > \fIpreg\fR\->\fIre_nsub\fR)\(emhave both
.I rm_so
and
.I rm_eo
set to \-1.
If a subexpression participated in the match several times,
the reported substring is the last one it matched.
(Note, as an example in particular, that when the RE `(b*)+' matches `bbb',
the parenthesized subexpression matches each of the three `b's and then
an infinite number of empty strings following the last `b',
so the reported substring is one of the empties.)
.PP
If REG_STARTEND is specified,
.I pmatch
must point to at least one
.I regmatch_t
(even if
.I nmatch
is 0 or REG_NOSUB was specified),
to hold the input offsets for REG_STARTEND.
Use for output is still entirely controlled by
.IR nmatch ;
if
.I nmatch
is 0 or REG_NOSUB was specified,
the value of
.IR pmatch [0]
will not be changed by a successful
.IR regexec .
.PP
.I Regerror
maps a non-zero
.I errcode
from either
.I regcomp
or
.I regexec
to a human-readable, printable message.
If
.I preg
is non-NULL,
the error code should have arisen from use of
the
.I regex_t
pointed to by
.IR preg ,
and if the error code came from
.IR regcomp ,
it should have been the result from the most recent
.I regcomp
using that
.IR regex_t .
.RI ( Regerror
may be able to supply a more detailed message using information
from the
.IR regex_t .)
.I Regerror
places the NUL-terminated message into the buffer pointed to by
.IR errbuf ,
limiting the length (including the NUL) to at most
.I errbuf_size
bytes.
If the whole message won't fit,
as much of it as will fit before the terminating NUL is supplied.
In any case,
the returned value is the size of buffer needed to hold the whole
message (including terminating NUL).
If
.I errbuf_size
is 0,
.I errbuf
is ignored but the return value is still correct.
.PP
If the
.I errcode
given to
.I regerror
is first ORed with REG_ITOA,
the ``message'' that results is the printable name of the error code,
e.g. ``REG_NOMATCH'',
rather than an explanation thereof.
If
.I errcode
is REG_ATOI,
then
.I preg
shall be non-NULL and the
.I re_endp
member of the structure it points to
must point to the printable name of an error code;
in this case, the result in
.I errbuf
is the decimal digits of
the numeric value of the error code
(0 if the name is not recognized).
REG_ITOA and REG_ATOI are intended primarily as debugging facilities;
they are extensions,
compatible with but not specified by POSIX 1003.2,
and should be used with
caution in software intended to be portable to other systems.
Be warned also that they are considered experimental and changes are possible.
.PP
.I Regfree
frees any dynamically-allocated storage associated with the compiled RE
pointed to by
.IR preg .
The remaining
.I regex_t
is no longer a valid compiled RE
and the effect of supplying it to
.I regexec
or
.I regerror
is undefined.
.PP
None of these functions references global variables except for tables
of constants;
all are safe for use from multiple threads if the arguments are safe.
.SH IMPLEMENTATION CHOICES
There are a number of decisions that 1003.2 leaves up to the implementor,
either by explicitly saying ``undefined'' or by virtue of them being
forbidden by the RE grammar.
This implementation treats them as follows.
.PP
See
.ZR
for a discussion of the definition of case-independent matching.
.PP
There is no particular limit on the length of REs,
except insofar as memory is limited.
Memory usage is approximately linear in RE size, and largely insensitive
to RE complexity, except for bounded repetitions.
See BUGS for one short RE using them
that will run almost any system out of memory.
.PP
A backslashed character other than one specifically given a magic meaning
by 1003.2 (such magic meanings occur only in obsolete [``basic''] REs)
is taken as an ordinary character.
.PP
Any unmatched [ is a REG_EBRACK error.
.PP
Equivalence classes cannot begin or end bracket-expression ranges.
The endpoint of one range cannot begin another.
.PP
RE_DUP_MAX, the limit on repetition counts in bounded repetitions, is 255.
.PP
A repetition operator (?, *, +, or bounds) cannot follow another
repetition operator.
A repetition operator cannot begin an expression or subexpression
or follow `^' or `|'.
.PP
`|' cannot appear first or last in a (sub)expression or after another `|',
i.e. an operand of `|' cannot be an empty subexpression.
An empty parenthesized subexpression, `()', is legal and matches an
empty (sub)string.
An empty string is not a legal RE.
.PP
A `{' followed by a digit is considered the beginning of bounds for a
bounded repetition, which must then follow the syntax for bounds.
A `{' \fInot\fR followed by a digit is considered an ordinary character.
.PP
`^' and `$' beginning and ending subexpressions in obsolete (``basic'')
REs are anchors, not ordinary characters.

Originally written by Henry Spencer at University of Toronto.
Altered for inclusion in the 4.4BSD distribution.
.SH BUGS
This is an alpha release with known defects.
Please report problems.
.PP
There is one known functionality bug.
The implementation of internationalization is incomplete:
the locale is always assumed to be the default one of 1003.2,
and only the collating elements etc. of that locale are available.
.PP
The back-reference code is subtle and doubts linger about its correctness
in complex cases.
.PP
.I Regexec
performance is poor.
This will improve with later releases.
.I Nmatch
exceeding 0 is expensive;
.I nmatch
exceeding 1 is worse.
.I Regexec
is largely insensitive to RE complexity \fIexcept\fR that back
references are massively expensive.
RE length does matter; in particular, there is a strong speed bonus
for keeping RE length under about 30 characters,
with most special characters counting roughly double.
.PP
.I Regcomp
implements bounded repetitions by macro expansion,
which is costly in time and space if counts are large
or bounded repetitions are nested.
An RE like, say,
`((((a{1,100}){1,100}){1,100}){1,100}){1,100}'
will (eventually) run almost any existing machine out of swap space.
.PP
There are suspected problems with response to obscure error conditions.
Notably,
certain kinds of internal overflow,
produced only by truly enormous REs or by multiply nested bounded repetitions,
are probably not handled well.
.PP
Due to a mistake in 1003.2, things like `a)b' are legal REs because `)' is
a special character only in the presence of a previous unmatched `('.
This can't be fixed until the spec is fixed.
.PP
The standard's definition of back references is vague.
For example, does
`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?
Until the standard is clarified,
behavior in such cases should not be relied on.
.PP
The implementation of word-boundary matching is a bit of a kludge,
and bugs may lurk in combinations of word-boundary matching and anchoring.

 * Repeated input in the historic vi is mostly wrong and this isn't very
 * backward compatible.  For example, if the user entered "3Aab\ncd" in
 * the historic vi, the "ab" was repeated 3 times, and the "\ncd" was then
 * appended to the result.  There was also a hack which I don't remember
 * right now, where "3o" would open 3 lines and then let the user fill them
 * in, to make screen movements on 300 baud modems more tolerable.  I don't
 * think it's going to be missed.
 *
 * !!!
 * There's a problem with the way that we do logging for change commands with
 * implied motions (e.g. A, I, O, cc, etc.).  Since the main vi loop logs the
 * starting cursor position before the change command "moves" the cursor, the
 * cursor position to which we return on undo will be where the user entered
 * the change command, not the start of the change.  Several of the following
 * routines re-log the cursor to make this work correctly.  Historic vi tried
 * to do the same thing, and mostly got it right.  (The only spectacular way
 * it fails is if the user entered 'o' from anywhere but the last character of
 * the line, the undo returned the cursor to the start of the line.  If the
 * user was on the last character of the line, the cursor returned to that
 * position.)  We also check for mapped keys waiting, i.e. if we're in the
 * middle of a map, don't bother logging the cursor.

 * The historic vi had a problem in that all movements were by physical
 * lines, not by logical, or screen lines.  Arguments can be made that this
 * is the right thing to do.  For example, single line movements, such as
 * 'j' or 'k', should probably work on physical lines.  Commands like "dj",
 * or "j.", where '.' is a change command, make more sense for physical lines
 * than they do for logical lines.
 *
 * These arguments, however, don't apply to scrolling commands like ^D and
 * ^F -- if the window is fairly small, using physical lines can result in
 * a half-page scroll repainting the entire screen, which is not what the
 * user wanted.  Second, if the line is larger than the screen, using physical
 * lines can make it impossible to display parts of the line -- there aren't
 * any commands that don't display the beginning of the line in historic vi,
 * and if both the beginning and end of the line can't be on the screen at
 * the same time, you lose.  This is even worse in the case of the H, L, and
 * M commands -- for large lines, they may all refer to the same line and
 * will result in no movement at all.
 *
 * Another issue is that page and half-page scrolling commands historically
 * moved to the first non-blank character in the new line.  If the line is
 * approximately the same size as the screen, this loses because the cursor
 * before and after a ^D, may refer to the same location on the screen.  In
 * this implementation, scrolling commands set the cursor to the first non-
 * blank character if the line changes because of the scroll.  Otherwise,
 * the cursor is left alone.
 *
 * This implementation does the scrolling (^B, ^D, ^F, ^U, ^Y, ^E), and the
 * cursor positioning commands (H, L, M) commands using logical lines, not
 * physical.

	 * Cleverly, it checked the replacement string for its unabbreviation

 * input, and permits the standard erase characters to erase the characters it
 * inserts.

	 * the user can undo multiple operations, we leave the old semantic
	 * unchanged, but make '.' after a 'u' do another undo/redo operation.
	 * This has two problems.
	 *
	 * The first is that 'u' didn't set '.' in historic vi.  So, if a
	 * user made a change, realized it was in the wrong place, does a
	 * 'u' to undo it, moves to the right place and then does '.', the
	 * change was reapplied.  To make this work, we only apply the '.'
	 * to the undo command if it's the command immediately following an
	 * undo command.  See vi/vi.c:getcmd() for the details.
	 *
	 * The second is that the traditional way to view the numbered cut
	 * buffers in vi was to enter the commands "1pu.u.u.u. which will
	 * no longer work because the '.' immediately follows the 'u' command.
	 * Since we provide a much better method of viewing buffers, and
	 * nobody can think of a better way of adding in multiple undo, this
	 * remains broken.
	 *
	 * !!!
	 * There is change to historic practice for the final cursor position
	 * in this implementation.  In historic vi, if an undo was isolated to
	 * a single line, the cursor moved to the start of the change, and
	 * then, subsequent 'u' commands would not move it again. (It has been
	 * pointed out that users used multiple undo commands to get the cursor
	 * to the start of the changed text.)  Nvi toggles between the cursor
	 * position before and after the change was made.  One final issue is
	 * that historic vi only did this if the user had not moved off of the
	 * line before entering the undo command; otherwise, vi would move the
	 * cursor to the most attractive position on the changed line.
	 *
	 * It would be difficult to match historic practice in this area. You
	 * not only have to know that the changes were isolated to one line,
	 * but whether it was the first or second undo command as well.  And,
	 * to completely match historic practice, we'd have to track users line
	 * changes, too.  This isn't worth the effort.

/*
 * There are two types of "words".  Bigwords are easy -- groups of anything
 * delimited by whitespace.  Normal words are trickier.  They are either a
 * group of characters, numbers and underscores, or a group of anything but,
 * delimited by whitespace.  When for a word, if you're in whitespace, it's
 * easy, just remove the whitespace and go to the beginning or end of the
 * word.  Otherwise, figure out if the next character is in a different group.
 * If it is, go to the beginning or end of that group, otherwise, go to the
 * beginning or end of the current group.  The historic version of vi didn't
 * get this right, so, for example, there were cases where "4e" was not the
 * same as "eeee" -- in particular, single character words, and commands that
 * began in whitespace were almost always handled incorrectly.  To get it right
 * you have to resolve the cursor after each search so that the look-ahead to
 * figure out what type of "word" the cursor is in will be correct.
 *
 * Empty lines, and lines that consist of only white-space characters count
 * as a single word, and the beginning and end of the file counts as an
 * infinite number of words.
 *
 * Movements associated with commands are different than movement commands.
 * For example, in "abc  def", with the cursor on the 'a', "cw" is from
 * 'a' to 'c', while "w" is from 'a' to 'd'.  In general, trailing white
 * space is discarded from the change movement.  Another example is that,
 * in the same string, a "cw" on any white space character replaces that
 * single character, and nothing else.  Ain't nothin' in here that's easy.
 *
 * One historic note -- in the original vi, the 'w', 'W' and 'B' commands
 * would treat groups of empty lines as individual words, i.e. the command
 * would move the cursor to each new empty line.  The 'e' and 'E' commands
 * would treat groups of empty lines as a single word, i.e. the first use
 * would move past the group of lines.  The 'b' command would just beep at
 * you, or, if you did it from the start of the line as part of a motion
 * command, go absolutely nuts.  If the lines contained only white-space
 * characters, the 'w' and 'W' commands would just beep at you, and the 'B',
 * 'b', 'E' and 'e' commands would treat the group as a single word, and
 * the 'B' and 'b' commands will treat the lines as individual words.  This
 * implementation treats all of these cases as a single white-space word.

	 * everything up to the next 'b' character.  While this implementation

	 * There are four cursor locations that we worry about: the initial
	 * cursor position, the start of the range, the end of the range,
	 * and the final cursor position.  The initial cursor position and
	 * the start of the range are both m_start, and are always the same.
	 * All locations are initialized to the starting cursor position by
	 * the main vi routines, and the underlying functions depend on this.
	 *
	 * Commands that can be motion components set the end of the range
	 * cursor position, m_stop.  All commands must set the ending cursor
	 * position, m_final.  The reason that m_stop isn't the same as m_final
	 * is that there are situations where the final position of the cursor
	 * is outside of the cut/delete range (e.g. 'd[[' from the first column
	 * of a line).  The final cursor position often varies based on the
	 * direction of the movement, as well as the command.  The only special
	 * case that the delete code handles is that it will make adjustments
	 * if the final cursor position is deleted.
	 *
	 * The reason for all of this is that the historic vi semantics were
	 * defined command-by-command.  Every function has to roll its own
	 * starting and stopping positions, and adjust them if it's being used
	 * as a motion component.  The general rules are as follows:
	 *
	 *	1: If not a motion component, the final cursor is at the end
	 *	   of the range.
	 *	2: If moving backward in the file, delete and yank move the
	 *	   final cursor to the end of the range.
	 *	3: If moving forward in the file, delete and yank leave the
	 *	   final cursor at the start of the range.
	 *
	 * Usually, if moving backward in the file and it's a motion component,
	 * the starting cursor is decremented by a single character (or, in a
	 * few cases, to the end of the previous line) so that the starting
	 * cursor character isn't cut or deleted.  No cursor adjustment is
	 * needed for moving forward, because the cut/delete routines handle
	 * m_stop inclusively, i.e. the last character in the range is cut or
	 * deleted.  This makes cutting to the EOF/EOL reasonable.
	 *
	 * The 'c', '<', '>', and '!' commands are special cases.  We ignore
	 * the final cursor position for all of them: for 'c', the text input
	 * routines set the cursor to the last character inserted; for '<',
	 * '>' and '!', the underlying ex commands that do the operation will
	 * set the cursor for us, usually to something related to the first
	 * .

 * We use a single "window" for each set of vi screens.  The model would be
 * simpler with two windows (one for the text, and one for the modeline)
 * because scrolling the text window down would work correctly then, not
 * affecting the mode line.  As it is we have to play games to make it look
 * right.  The reason for this choice is that it would be difficult for
 * curses to optimize the movement, i.e. detect that the downward scroll
 * isn't going to change the modeline, set the scrolling region on the
 * terminal and only scroll the first part of the text window.
 *
 * Structure for mapping lines to the screen.  An SMAP is an array, with one
 * structure element per screen line, which holds information describing the
 * physical line which is displayed in the screen line.  The first two fields
 * (lno and off) are all that are necessary to describe a line.  The rest of
 * the information is useful to keep information from being re-calculated.
 *
 * The SMAP always has an entry for each line of the physical screen, plus a
 * slot for the colon command line, so there is room to add any screen into
 * another one at screen exit.
 *
 * Lno is the line number.  If doing the historic vi long line folding, soff
 * is the screen offset into the line.  For example, the pair 2:1 would be
 * the first screen of line 2, and 2:2 would be the second.  In the case of
 * long lines, the screen map will tend to be staggered, e.g., 1:1, 1:2, 1:3,
 * 2:1, 3:1, etc.  If doing left-right scrolling, the coff field is the screen
 * column offset into the lines, and can take on any value, as it's adjusted
 * by the user set value O_SIDESCROLL.

	 *	2: The screen would scroll, showing the line
	 *	3: The screen would compress to its smallest size and
	 *		repaint.
	 * In general, scrolling didn't cause compression (200^D was handled
	 * the same as ^D), movement to a specific line would (:N where N
	 * was 1 line below the screen caused a screen compress), and cursor
	 * movement would scroll if it was 11 lines or less, and compress if

	 * What we do is try and figure out if the line is less than half of

	 * room, and then scroll as necessary.  The alternative is to compress
	 * and repaint.
