We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. 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.

The file is not * writable on a read-only file system even if this test indicates true. * * Unfortunately IEEE POSIX 1003.1-2001, as quoted in SuSv3, says only: * * True shall indicate that permission to read from file will be granted, * as defined in "File Read, Write, and Creation". * * and that section says: * * When a file is to be read or written, the file shall be opened with an * access mode corresponding to the operation to be performed. If file * access permissions deny access, the requested operation shall fail. * * and of course access permissions are described as one might expect: * * * If a process has the appropriate privilege: * * * If read, write, or directory search permission is requested, * access shall be granted. * * * If execute permission is requested, access shall be granted if * execute permission is granted to at least one user by the file * permission bits or by an alternate access control mechanism; * otherwise, access shall be denied. * * * Otherwise: * * * The file permission bits of a file contain read, write, and * execute/search permissions for the file owner class, file group * class, and file other class. * * * Access shall be granted if an alternate access control mechanism * is not enabled and the requested access permission bit is set for * the class (file owner class, file group class, or file other class) * to which the process belongs, or if an alternate access control * mechanism is enabled and it allows the requested access; otherwise, * access shall be denied. * * and when I first read this I thought: surely we can't go about using * open(O_WRONLY) to try this test! However the POSIX 1003.1-2001 Rationale * section for test does in fact say: * * On historical BSD systems, test -w directory always returned false * because test tried to open the directory for writing, which always * fails. * * and indeed this is in fact true for Seventh Edition UNIX, UNIX 32V, and UNIX * System III, and thus presumably also for BSD up to and including 4.3. * * Secondly I remembered why using open() and/or access() are bogus. They * don't work right for detecting read and write permissions bits when called * by root. * * Interestingly the 'test' in 4.4BSD was closer to correct (as per * 1003.2-1992) and it was implemented efficiently with stat() instead of * open(). * * This was apparently broken in NetBSD around about 1994/06/30 when the old * 4.4BSD implementation was replaced with a (arguably much better coded) * implementation derived from pdksh. * * Note that modern pdksh is yet different again, but still not correct, at * least not w.r.t. 1003.2-1992. * * As I think more about it and read more of the related IEEE docs I don't like * that wording about 'test -r' and 'test -w' in 1003.1-2001 at all. I very * much prefer the original wording in 1003.2-1992. It is much more useful, * and so that's what I've implemented. * * (Note that a strictly conforming implementation of 1003.1-2001 is in fact * totally useless for the case in question since its 'test -w' and 'test -r' * can never fail for root for any existing files, i.e. files for which 'test * -e' succeeds.) * * The rationale for 1003.1-2001 suggests that the wording was "clarified" in * 1003.1-2001 to align with the 1003.2b draft. 1003.2b Draft 12 (July 1999), * which is the latest copy I have, does carry the same suggested wording as is * in 1003.1-2001, with its rationale saying: * * This change is a clarification and is the result of interpretation * request PASC 1003.2-92 #23 submitted for IEEE Std 1003.2-1992. * * That interpretation can be found here: * * http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-23.html * * Not terribly helpful, unfortunately. I wonder who that fence sitter was. * * Worse, IMVNSHO, I think the authors of 1003.2b-D12 have mis-interpreted the * PASC interpretation and appear to be gone against at least one widely used * implementation (namely 4.4BSD). The problem is that for file access by root * this means that if test '-r' and '-w' are to behave as if open() were called * then there's no way for a shell script running as root to check if a file * has certain access bits set other than by the grotty means of interpreting * the output of 'ls -l'. This was widely considered to be a bug in V7's * "test" and is, I believe, one of the reasons why direct use of access() was * avoided in some more recent implementations! * * I have always interpreted '-r' to match '-w' and '-x' as per the original * wording in 1003.2-1992, not the other way around. I think 1003.2b goes much * too far the wrong way without any valid rationale and that it's best if we * stick with 1003.2-1992 and test the flags, and not mimic the behaviour of * open() since we already know very well how it will work -- existance of the * file is all that matters to open() for root. * * Unfortunately the SVID is no help at all (which is, I guess, partly why * we're in this mess in the first place :-). * * The SysV implementation (at least in the 'test' builtin in /bin/sh) does use * access(name, 2) even though it also goes to much greater lengths for '-x' * matching the 1003.2-1992 definition (which is no doubt where that definition * came from). * * The ksh93 implementation uses access() for '-r' and '-w' if * (euid==uid&&egid==gid), but uses st_mode for '-x' iff running as root. * i.e. it does strictly conform to 1003.1-2001 (and presumably 1003.2b). */ static int test_access(const struct stat64 *sp, int stmode) { gid_t *groups; register int n; uid_t euid; int maxgroups; /* * I suppose we could use access() if not running as root and if we are * running with ((euid == uid) && (egid == gid)), but we've already * done the stat() so we might as well just test the permissions * directly instead of asking the kernel to do it.... */ euid = geteuid(); if (euid == 0) { if (stmode != X_OK) return 1; /* any bit is good enough */ stmode = (stmode << 6) | (stmode << 3) | stmode; } else if (sp->st_uid == euid) stmode <<= 6; else if (sp->st_gid == getegid()) stmode <<= 3; else { /* XXX stolen almost verbatim from ksh93.... */ /* on some systems you can be in several groups */ maxgroups = getgroups(0, NULL); groups = stalloc(maxgroups * sizeof(*groups)); n = getgroups(maxgroups, groups); while (--n >= 0) { if (groups[n] == sp->st_gid) { stmode <<= 3; break; } } } return sp->st_mode & stmode; } #endif /* HAVE_FACCESSAT */ dash-0.5.12/src/bltin/printf.c0000644000175000017500000002301713665575233013026 00000000000000/* * Copyright (c) 1989, 1993 * The Regents of the University of California.

The current version of .Nm is in the process of being changed to conform with the .Tn POSIX 1003.2 and 1003.2a specifications for the shell. This version has many features which make it appear similar in some respects to the Korn shell, but it is not a Korn shell clone (see .Xr ksh 1 ) . Only features designated by .Tn POSIX , plus a few Berkeley extensions, are being incorporated into this shell. This man page is not intended to be a tutorial or a complete specification of the shell. .Ss Overview The shell is a command that reads lines from either a file or the terminal, interprets them, and generally executes other commands. It is the program that is running when a user logs into the system (although a user can select a different shell with the .Xr chsh 1 command). The shell implements a language that has flow control constructs, a macro facility that provides a variety of features in addition to data storage, along with built in history and line editing capabilities. It incorporates many features to aid interactive use and has the advantage that the interpretative language is common to both interactive and non-interactive use (shell scripts). That is, commands can be typed directly to the running shell or can be put into a file and the file can be executed directly by the shell. .Ss Invocation If no args are present and if the standard input of the shell is connected to a terminal (or if the .Fl i flag is set), and the .Fl c option is not present, the shell is considered an interactive shell. An interactive shell generally prompts before each command and handles programming and command errors differently (as described below). When first starting, the shell inspects argument 0, and if it begins with a dash .Sq - , the shell is also considered a login shell. This is normally done automatically by the system when the user first logs in. A login shell first reads commands from the files .Pa /etc/profile and .Pa .profile if they exist. If the environment variable .Ev ENV is set on entry to an interactive shell, or is set in the .Pa .profile of a login shell, the shell next reads commands from the file named in .Ev ENV . Therefore, a user should place commands that are to be executed only at login time in the .Pa .profile file, and commands that are executed for every interactive shell inside the .Ev ENV file. To set the .Ev ENV variable to some file, place the following line in your .Pa .profile of your home directory .Pp .Dl ENV=$HOME/.shinit; export ENV .Pp substituting for .Dq .shinit any filename you wish. .Pp If command line arguments besides the options have been specified, then the shell treats the first argument as the name of a file from which to read commands (a shell script), and the remaining arguments are set as the positional parameters of the shell ($1, $2, etc). Otherwise, the shell reads commands from its standard input. .Ss Argument List Processing All of the single letter options that have a corresponding name can be used as an argument to the .Fl o option. The set .Fl o name is provided next to the single letter option in the description below. Specifying a dash .Dq - turns the option on, while using a plus .Dq + disables the option. The following options can be set from the command line or with the .Ic set builtin (described later). .Bl -tag -width aaaallexportfoo -offset indent .It Fl a Em allexport Export all variables assigned to. .It Fl c Read commands from the .Ar command_string operand instead of from the standard input. Special parameter 0 will be set from the .Ar command_name operand and the positional parameters ($1, $2, etc.) set from the remaining argument operands. .It Fl C Em noclobber Don't overwrite existing files with .Dq \*[Gt] . .It Fl e Em errexit If not interactive, exit immediately if any untested command fails. The exit status of a command is considered to be explicitly tested if the command is used to control an .Ic if , .Ic elif , .Ic while , or .Ic until ; or if the command is the left hand operand of an .Dq && or .Dq || operator. .It Fl f Em noglob Disable pathname expansion. .It Fl n Em noexec If not interactive, read commands but do not execute them. This is useful for checking the syntax of shell scripts. .It Fl u Em nounset Write a message to standard error when attempting to expand a variable that is not set, and if the shell is not interactive, exit immediately. .It Fl v Em verbose The shell writes its input to standard error as it is read. Useful for debugging. .It Fl x Em xtrace Write each command to standard error (preceded by a .Sq +\ ) before it is executed. Useful for debugging. .It Fl I Em ignoreeof Ignore EOF's from input when interactive. .It Fl i Em interactive Force the shell to behave interactively. .It Fl l Make dash act as if it had been invoked as a login shell. .It Fl m Em monitor Turn on job control (set automatically when interactive). .It Fl s Em stdin Read commands from standard input (set automatically if no file arguments are present). This option has no effect when set after the shell has already started running (i.e. with .Ic set ) . .It Fl V Em vi Enable the built-in .Xr vi 1 command line editor (disables .Fl E if it has been set). .It Fl E Em emacs Enable the built-in .Xr emacs 1 command line editor (disables .Fl V if it has been set). .It Fl b Em notify Enable asynchronous notification of background job completion. (UNIMPLEMENTED for 4.4alpha) .El .Ss Lexical Structure The shell reads input in terms of lines from a file and breaks it up into words at whitespace (blanks and tabs), and at certain sequences of characters that are special to the shell called .Dq operators . There are two types of operators: control operators and redirection operators (their meaning is discussed later). Following is a list of operators: .Bl -ohang -offset indent .It "Control operators:" .Dl & && \&( \&) \&; ;; | || \*[Lt]newline\*[Gt] .It "Redirection operators:" .Dl \*[Lt] \*[Gt] \*[Gt]| \*[Lt]\*[Lt] \*[Gt]\*[Gt] \*[Lt]& \*[Gt]& \*[Lt]\*[Lt]- \*[Lt]\*[Gt] .El .Ss Quoting Quoting is used to remove the special meaning of certain characters or words to the shell, such as operators, whitespace, or keywords. There are three types of quoting: matched single quotes, matched double quotes, and backslash. .Ss Backslash A backslash preserves the literal meaning of the following character, with the exception of .Aq newline . A backslash preceding a .Aq newline is treated as a line continuation. .Ss Single Quotes Enclosing characters in single quotes preserves the literal meaning of all the characters (except single quotes, making it impossible to put single-quotes in a single-quoted string). .Ss Double Quotes Enclosing characters within double quotes preserves the literal meaning of all characters except dollarsign .Pq $ , backquote .Pq ` , and backslash .Pq \e . The backslash inside double quotes is historically weird, and serves to quote only the following characters: .Dl $ ` \*q \e \*[Lt]newline\*[Gt] . Otherwise it remains literal. .Ss Reserved Words Reserved words are words that have special meaning to the shell and are recognized at the beginning of a line and after a control operator. The following are reserved words: .Bl -column while while while while while -offset indent .It ! Ta elif Ta fi Ta while Ta case .It else Ta for Ta then Ta { Ta } .It do Ta done Ta until Ta if Ta esac .El .Pp Their meaning is discussed later. .Ss Aliases An alias is a name and corresponding value set using the .Xr alias 1 builtin command. Whenever a reserved word may occur (see above), and after checking for reserved words, the shell checks the word to see if it matches an alias. If it does, it replaces it in the input stream with its value. For example, if there is an alias called .Dq lf with the value .Dq "ls -F" , then the input: .Pp .Dl lf foobar Aq return .Pp would become .Pp .Dl ls -F foobar Aq return .Pp Aliases provide a convenient way for naive users to create shorthands for commands without having to learn how to create functions with arguments. They can also be used to create lexically obscure code. This use is discouraged. .Ss Commands The shell interprets the words it reads according to a language, the specification of which is outside the scope of this man page (refer to the BNF in the .Tn POSIX 1003.2 document). Essentially though, a line is read and if the first word of the line (or after a control operator) is not a reserved word, then the shell has recognized a simple command. Otherwise, a complex command or some other special construct may have been recognized. .Ss Simple Commands If a simple command has been recognized, the shell performs the following actions: .Bl -enum -offset indent .It Leading words of the form .Dq name=value are stripped off and assigned to the environment of the simple command. Redirection operators and their arguments (as described below) are stripped off and saved for processing. .It The remaining words are expanded as described in the section called .Dq Expansions , and the first remaining word is considered the command name and the command is located. The remaining words are considered the arguments of the command. If no command name resulted, then the .Dq name=value variable assignments recognized in item 1 affect the current shell. .It Redirections are performed as described in the next section. .El .Ss Redirections Redirections are used to change where a command reads its input or sends its output. In general, redirections open, close, or duplicate an existing reference to a file. The overall format used for redirection is: .Pp .Dl [n] Va redir-op Ar file .Pp where .Va redir-op is one of the redirection operators mentioned previously. Following is a list of the possible redirections. The .Bq n is an optional number between 0 and 9, as in .Sq 3 (not .Sq Bq 3 ) , that refers to a file descriptor. .Bl -tag -width aaabsfiles -offset indent .It [n] Ns \*[Gt] file Redirect standard output (or n) to file. .It [n] Ns \*[Gt]| file Same, but override the .Fl C option. .It [n] Ns \*[Gt]\*[Gt] file Append standard output (or n) to file. .It [n] Ns \*[Lt] file Redirect standard input (or n) from file. .It [n1] Ns \*[Lt]& Ns n2 Copy file descriptor n2 as stdout (or fd n1). fd n2. .It [n] Ns \*[Lt]&- Close standard input (or n). .It [n1] Ns \*[Gt]& Ns n2 Copy file descriptor n2 as stdin (or fd n1). fd n2. .It [n] Ns \*[Gt]&- Close standard output (or n). .It [n] Ns \*[Lt]\*[Gt] file Open file for reading and writing on standard input (or n). .El .Pp The following redirection is often called a .Dq here-document . .Bl -item -offset indent .It .Li [n]\*[Lt]\*[Lt] delimiter .Dl here-doc-text ... .Li delimiter .El .Pp All the text on successive lines up to the delimiter is saved away and made available to the command on standard input, or file descriptor n if it is specified. If the delimiter as specified on the initial line is quoted, then the here-doc-text is treated literally, otherwise the text is subjected to parameter expansion, command substitution, and arithmetic expansion (as described in the section on .Dq Expansions ) . If the operator is .Dq \*[Lt]\*[Lt]- instead of .Dq \*[Lt]\*[Lt] , then leading tabs in the here-doc-text are stripped. .Ss Search and Execution There are three types of commands: shell functions, builtin commands, and normal programs \(en and the command is searched for (by name) in that order. They each are executed in a different way. .Pp When a shell function is executed, all of the shell positional parameters (except $0, which remains unchanged) are set to the arguments of the shell function. The variables which are explicitly placed in the environment of the command (by placing assignments to them before the function name) are made local to the function and are set to the values given. Then the command given in the function definition is executed. The positional parameters are restored to their original values when the command completes. This all occurs within the current shell. .Pp Shell builtins are executed internally to the shell, without spawning a new process. .Pp Otherwise, if the command name doesn't match a function or builtin, the command is searched for as a normal program in the file system (as described in the next section). When a normal program is executed, the shell runs the program, passing the arguments and the environment to the program. If the program is not a normal executable file (i.e., if it does not begin with the "magic number" whose .Tn ASCII representation is "#!", so .Xr execve 2 returns .Er ENOEXEC then) the shell will interpret the program in a subshell. The child shell will reinitialize itself in this case, so that the effect will be as if a new shell had been invoked to handle the ad-hoc shell script, except that the location of hashed commands located in the parent shell will be remembered by the child. .Pp Note that previous versions of this document and the source code itself misleadingly and sporadically refer to a shell script without a magic number as a "shell procedure". .Ss Path Search When locating a command, the shell first looks to see if it has a shell function by that name. Then it looks for a builtin command by that name. If a builtin command is not found, one of two things happen: .Bl -enum .It Command names containing a slash are simply executed without performing any searches. .It The shell searches each entry in .Ev PATH in turn for the command. The value of the .Ev PATH variable should be a series of entries separated by colons. Each entry consists of a directory name. The current directory may be indicated implicitly by an empty directory name, or explicitly by a single period. .El .Ss Command Exit Status Each command has an exit status that can influence the behaviour of other shell commands. The paradigm is that a command exits with zero for normal or success, and non-zero for failure, error, or a false indication. The man page for each command should indicate the various exit codes and what they mean. Additionally, the builtin commands return exit codes, as does an executed shell function. .Pp If a command consists entirely of variable assignments then the exit status of the command is that of the last command substitution if any, otherwise 0. .Ss Complex Commands Complex commands are combinations of simple commands with control operators or reserved words, together creating a larger complex command. More generally, a command is one of the following: .Bl -bullet .It simple command .It pipeline .It list or compound-list .It compound command .It function definition .El .Pp Unless otherwise stated, the exit status of a command is that of the last simple command executed by the command. .Ss Pipelines A pipeline is a sequence of one or more commands separated by the control operator |. The standard output of all but the last command is connected to the standard input of the next command. The standard output of the last command is inherited from the shell, as usual. .Pp The format for a pipeline is: .Pp .Dl [!] command1 [ | command2 ...] .Pp The standard output of command1 is connected to the standard input of command2. The standard input, standard output, or both of a command is considered to be assigned by the pipeline before any redirection specified by redirection operators that are part of the command. .Pp If the pipeline is not in the background (discussed later), the shell waits for all commands to complete. .Pp If the reserved word ! does not precede the pipeline, the exit status is the exit status of the last command specified in the pipeline. Otherwise, the exit status is the logical NOT of the exit status of the last command. That is, if the last command returns zero, the exit status is 1; if the last command returns greater than zero, the exit status is zero. .Pp Because pipeline assignment of standard input or standard output or both takes place before redirection, it can be modified by redirection. For example: .Pp .Dl $ command1 2\*[Gt]&1 | command2 .Pp sends both the standard output and standard error of command1 to the standard input of command2. .Pp A ; or .Aq newline terminator causes the preceding AND-OR-list (described next) to be executed sequentially; a & causes asynchronous execution of the preceding AND-OR-list. .Pp Note that unlike some other shells, each process in the pipeline is a child of the invoking shell (unless it is a shell builtin, in which case it executes in the current shell \(en but any effect it has on the environment is wiped). .Ss Background Commands \(en & If a command is terminated by the control operator ampersand (&), the shell executes the command asynchronously \(en that is, the shell does not wait for the command to finish before executing the next command. .Pp The format for running a command in background is: .Pp .Dl command1 & [command2 & ...] .Pp If the shell is not interactive, the standard input of an asynchronous command is set to .Pa /dev/null . .Ss Lists \(en Generally Speaking A list is a sequence of zero or more commands separated by newlines, semicolons, or ampersands, and optionally terminated by one of these three characters. The commands in a list are executed in the order they are written. If command is followed by an ampersand, the shell starts the command and immediately proceeds onto the next command; otherwise it waits for the command to terminate before proceeding to the next one. .Ss Short-Circuit List Operators .Dq && and .Dq || are AND-OR list operators. .Dq && executes the first command, and then executes the second command if and only if the exit status of the first command is zero. .Dq || is similar, but executes the second command if and only if the exit status of the first command is nonzero. .Dq && and .Dq || both have the same priority. .Ss Flow-Control Constructs \(en if, while, for, case The syntax of the if command is .Bd -literal -offset indent if list then list [ elif list then list ] ... [ else list ] fi .Ed .Pp The syntax of the while command is .Bd -literal -offset indent while list do list done .Ed .Pp The two lists are executed repeatedly while the exit status of the first list is zero. The until command is similar, but has the word until in place of while, which causes it to repeat until the exit status of the first list is zero. .Pp The syntax of the for command is .Bd -literal -offset indent for variable [ in [ word ... ] ] do list done .Ed .Pp The words following .Pa in are expanded, and then the list is executed repeatedly with the variable set to each word in turn. Omitting in word ... is equivalent to in "$@". .Pp The syntax of the break and continue command is .Bd -literal -offset indent break [ num ] continue [ num ] .Ed .Pp Break terminates the num innermost for or while loops. Continue continues with the next iteration of the innermost loop. These are implemented as builtin commands. .Pp The syntax of the case command is .Bd -literal -offset indent case word in [(]pattern) list ;; \&... esac .Ed .Pp The pattern can actually be one or more patterns (see .Sx Shell Patterns described later), separated by .Dq \*(Ba characters. The .Do ( .Dc character before the pattern is optional. .Ss Grouping Commands Together Commands may be grouped by writing either .Pp .Dl (list) .Pp or .Pp .Dl { list; } .Pp The first of these executes the commands in a subshell. Builtin commands grouped into a (list) will not affect the current shell. The second form does not fork another shell so is slightly more efficient. Grouping commands together this way allows you to redirect their output as though they were one program: .\".Pp .Bd -literal -offset indent { printf \*q hello \*q ; printf \*q world\\n" ; } \*[Gt] greeting .Ed .Pp Note that .Dq } must follow a control operator (here, .Dq \&; ) so that it is recognized as a reserved word and not as another command argument. .Ss Functions The syntax of a function definition is .Pp .Dl name ( ) command .Pp A function definition is an executable statement; when executed it installs a function named name and returns an exit status of zero. The command is normally a list enclosed between .Dq { and .Dq } . .Pp Variables may be declared to be local to a function by using a local command. This should appear as the first statement of a function, and the syntax is .Pp .Dl local [ variable | - ] ... .Pp Local is implemented as a builtin command. .Pp When a variable is made local, it inherits the initial value and exported and readonly flags from the variable with the same name in the surrounding scope, if there is one. Otherwise, the variable is initially unset. The shell uses dynamic scoping, so that if you make the variable x local to function f, which then calls function g, references to the variable x made inside g will refer to the variable x declared inside f, not to the global variable named x. .Pp The only special parameter that can be made local is .Dq - . Making .Dq - local any shell options that are changed via the set command inside the function to be restored to their original values when the function returns. .Pp The syntax of the return command is .Pp .Dl return [ exitstatus ] .Pp It terminates the currently executing function. Return is implemented as a builtin command. .Ss Variables and Parameters The shell maintains a set of parameters. A parameter denoted by a name is called a variable. When starting up, the shell turns all the environment variables into shell variables. New variables can be set using the form .Pp .Dl name=value .Pp Variables set by the user must have a name consisting solely of alphabetics, numerics, and underscores - the first of which must not be numeric. A parameter can also be denoted by a number or a special character as explained below. .Ss Positional Parameters A positional parameter is a parameter denoted by a number (n \*[Gt] 0). The shell sets these initially to the values of its command line arguments that follow the name of the shell script. The .Ic set builtin can also be used to set or reset them. .Ss Special Parameters A special parameter is a parameter denoted by one of the following special characters. The value of the parameter is listed next to its character. .Bl -tag -width thinhyphena .It * Expands to the positional parameters, starting from one. When the expansion occurs within a double-quoted string it expands to a single field with the value of each parameter separated by the first character of the .Ev IFS variable, or by a .Aq space if .Ev IFS is unset. .It @ Expands to the positional parameters, starting from one. When the expansion occurs within double-quotes, each positional parameter expands as a separate argument. If there are no positional parameters, the expansion of @ generates zero arguments, even when @ is double-quoted. What this basically means, for example, is if $1 is .Dq abc and $2 is .Dq def ghi , then .Qq $@ expands to the two arguments: .Pp .Sm off .Dl \*q abc \*q \ \*q def\ ghi \*q .Sm on .It # Expands to the number of positional parameters. .It ? Expands to the exit status of the most recent pipeline. .It - (Hyphen.) Expands to the current option flags (the single-letter option names concatenated into a string) as specified on invocation, by the set builtin command, or implicitly by the shell. .It $ Expands to the process ID of the invoked shell. A subshell retains the same value of $ as its parent. .It ! Expands to the process ID of the most recent background command executed from the current shell. For a pipeline, the process ID is that of the last command in the pipeline. .It 0 (Zero.) Expands to the name of the shell or shell script. .El .Ss Word Expansions This clause describes the various expansions that are performed on words. Not all expansions are performed on every word, as explained later. .Pp Tilde expansions, parameter expansions, command substitutions, arithmetic expansions, and quote removals that occur within a single word expand to a single field. It is only field splitting or pathname expansion that can create multiple fields from a single word. The single exception to this rule is the expansion of the special parameter @ within double-quotes, as was described above. .Pp The order of word expansion is: .Bl -enum .It Tilde Expansion, Parameter Expansion, Command Substitution, Arithmetic Expansion (these all occur at the same time). .It Field Splitting is performed on fields generated by step (1) unless the .Ev IFS variable is null. .It Pathname Expansion (unless set .Fl f is in effect). .It Quote Removal. .El .Pp The $ character is used to introduce parameter expansion, command substitution, or arithmetic evaluation. .Ss Tilde Expansion (substituting a user's home directory) A word beginning with an unquoted tilde character (~) is subjected to tilde expansion. All the characters up to a slash (/) or the end of the word are treated as a username and are replaced with the user's home directory. If the username is missing (as in .Pa ~/foobar ) , the tilde is replaced with the value of the .Va HOME variable (the current user's home directory). .Ss Parameter Expansion The format for parameter expansion is as follows: .Pp .Dl ${expression} .Pp where expression consists of all characters until the matching .Dq } . Any .Dq } escaped by a backslash or within a quoted string, and characters in embedded arithmetic expansions, command substitutions, and variable expansions, are not examined in determining the matching .Dq } . .Pp The simplest form for parameter expansion is: .Pp .Dl ${parameter} .Pp The value, if any, of parameter is substituted. .Pp The parameter name or symbol can be enclosed in braces, which are optional except for positional parameters with more than one digit or when parameter is followed by a character that could be interpreted as part of the name. If a parameter expansion occurs inside double-quotes: .Bl -enum .It Pathname expansion is not performed on the results of the expansion. .It Field splitting is not performed on the results of the expansion, with the exception of @. .El .Pp In addition, a parameter expansion can be modified by using one of the following formats. .Bl -tag -width aaparameterwordaaaaa .It ${parameter:-word} Use Default Values. If parameter is unset or null, the expansion of word is substituted; otherwise, the value of parameter is substituted. .It ${parameter:=word} Assign Default Values. If parameter is unset or null, the expansion of word is assigned to parameter. In all cases, the final value of parameter is substituted. Only variables, not positional parameters or special parameters, can be assigned in this way. .It ${parameter:?[word]} Indicate Error if Null or Unset. If parameter is unset or null, the expansion of word (or a message indicating it is unset if word is omitted) is written to standard error and the shell exits with a nonzero exit status. Otherwise, the value of parameter is substituted. An interactive shell need not exit. .It ${parameter:+word} Use Alternative Value. If parameter is unset or null, null is substituted; otherwise, the expansion of word is substituted. .El .Pp In the parameter expansions shown previously, use of the colon in the format results in a test for a parameter that is unset or null; omission of the colon results in a test for a parameter that is only unset. .Bl -tag -width aaparameterwordaaaaa .It ${#parameter} String Length. The length in characters of the value of parameter. .El .Pp The following four varieties of parameter expansion provide for substring processing. In each case, pattern matching notation (see .Sx Shell Patterns ) , rather than regular expression notation, is used to evaluate the patterns. If parameter is * or @, the result of the expansion is unspecified. Enclosing the full parameter expansion string in double-quotes does not cause the following four varieties of pattern characters to be quoted, whereas quoting characters within the braces has this effect. .Bl -tag -width aaparameterwordaaaaa .It ${parameter%word} Remove Smallest Suffix Pattern. The word is expanded to produce a pattern. The parameter expansion then results in parameter, with the smallest portion of the suffix matched by the pattern deleted. .It ${parameter%%word} Remove Largest Suffix Pattern. The word is expanded to produce a pattern. The parameter expansion then results in parameter, with the largest portion of the suffix matched by the pattern deleted. .It ${parameter#word} Remove Smallest Prefix Pattern. The word is expanded to produce a pattern. The parameter expansion then results in parameter, with the smallest portion of the prefix matched by the pattern deleted. .It ${parameter##word} Remove Largest Prefix Pattern. The word is expanded to produce a pattern. The parameter expansion then results in parameter, with the largest portion of the prefix matched by the pattern deleted. .El .Ss Command Substitution Command substitution allows the output of a command to be substituted in place of the command name itself. Command substitution occurs when the command is enclosed as follows: .Pp .Dl $(command) .Pp or .Po .Dq backquoted version .Pc : .Pp .Dl `command` .Pp The shell expands the command substitution by executing command in a subshell environment and replacing the command substitution with the standard output of the command, removing sequences of one or more .Ao newline Ac Ns s at the end of the substitution. (Embedded .Ao newline Ac Ns s before the end of the output are not removed; however, during field splitting, they may be translated into .Ao space Ac Ns s , depending on the value of .Ev IFS and quoting that is in effect.) .Ss Arithmetic Expansion Arithmetic expansion provides a mechanism for evaluating an arithmetic expression and substituting its value. The format for arithmetic expansion is as follows: .Pp .Dl $((expression)) .Pp The expression is treated as if it were in double-quotes, except that a double-quote inside the expression is not treated specially. The shell expands all tokens in the expression for parameter expansion, command substitution, and quote removal. .Pp Next, the shell treats this as an arithmetic expression and substitutes the value of the expression. .Ss White Space Splitting (Field Splitting) After parameter expansion, command substitution, and arithmetic expansion the shell scans the results of expansions and substitutions that did not occur in double-quotes for field splitting and multiple fields can result. .Pp The shell treats each character of the .Ev IFS as a delimiter and uses the delimiters to split the results of parameter expansion and command substitution into fields. .Ss Pathname Expansion (File Name Generation) Unless the .Fl f flag is set, file name generation is performed after word splitting is complete. Each word is viewed as a series of patterns, separated by slashes. The process of expansion replaces the word with the names of all existing files whose names can be formed by replacing each pattern with a string that matches the specified pattern. There are two restrictions on this: first, a pattern cannot match a string containing a slash, and second, a pattern cannot match a string starting with a period unless the first character of the pattern is a period. The next section describes the patterns used for both Pathname Expansion and the .Ic case command. .Ss Shell Patterns A pattern consists of normal characters, which match themselves, and meta-characters. The meta-characters are .Dq \&! , .Dq * , .Dq \&? , and .Dq \&[ . These characters lose their special meanings if they are quoted. When command or variable substitution is performed and the dollar sign or back quotes are not double quoted, the value of the variable or the output of the command is scanned for these characters and they are turned into meta-characters. .Pp An asterisk .Pq Dq * matches any string of characters. A question mark matches any single character. A left bracket .Pq Dq \&[ introduces a character class. The end of the character class is indicated by a .Pq Dq \&] ; if the .Dq \&] is missing then the .Dq \&[ matches a .Dq \&[ rather than introducing a character class. A character class matches any of the characters between the square brackets. A range of characters may be specified using a minus sign. The character class may be complemented by making an exclamation point the first character of the character class. .Pp To include a .Dq \&] in a character class, make it the first character listed (after the .Dq \&! , if any). To include a minus sign, make it the first or last character listed. .Ss Builtins This section lists the builtin commands which are builtin because they need to perform some operation that can't be performed by a separate process. In addition to these, there are several other commands that may be builtin for efficiency (e.g. .Xr printf 1 , .Xr echo 1 , .Xr test 1 , etc). .Bl -tag -width 5n .It : .It true A null command that returns a 0 (true) exit value. .It \&. file The commands in the specified file are read and executed by the shell. .It alias Op Ar name Ns Op Ar "=string ..." If .Ar name=string is specified, the shell defines the alias .Ar name with value .Ar string . If just .Ar name is specified, the value of the alias .Ar name is printed. With no arguments, the .Ic alias builtin prints the names and values of all defined aliases (see .Ic unalias ) . .It bg [ Ar job ] ... Continue the specified jobs (or the current job if no jobs are given) in the background. .It Xo command .Op Fl p .Op Fl v .Op Fl V .Ar command .Op Ar arg ... .Xc Execute the specified command but ignore shell functions when searching for it. (This is useful when you have a shell function with the same name as a builtin command.) .Bl -tag -width 5n .It Fl p search for command using a .Ev PATH that guarantees to find all the standard utilities. .It Fl V Do not execute the command but search for the command and print the resolution of the command search. This is the same as the type builtin. .It Fl v Do not execute the command but search for the command and print the absolute pathname of utilities, the name for builtins or the expansion of aliases. .El .It cd Ar - .It Xo cd Op Fl LP .Op Ar directory .Xc Switch to the specified directory (default .Ev HOME ) . If an entry for .Ev CDPATH appears in the environment of the .Ic cd command or the shell variable .Ev CDPATH is set and the directory name does not begin with a slash, then the directories listed in .Ev CDPATH will be searched for the specified directory. The format of .Ev CDPATH is the same as that of .Ev PATH . If a single dash is specified as the argument, it will be replaced by the value of .Ev OLDPWD . The .Ic cd command will print out the name of the directory that it actually switched to if this is different from the name that the user gave. These may be different either because the .Ev CDPATH mechanism was used or because the argument is a single dash. The .Fl P option causes the physical directory structure to be used, that is, all symbolic links are resolved to their respective values. The .Fl L option turns off the effect of any preceding .Fl P options. .It Xo echo Op Fl n .Ar args... .Xc Print the arguments on the standard output, separated by spaces. Unless the .Fl n option is present, a newline is output following the arguments. .Pp If any of the following sequences of characters is encountered during output, the sequence is not output. Instead, the specified action is performed: .Bl -tag -width indent .It Li \eb A backspace character is output. .It Li \ec Subsequent output is suppressed. This is normally used at the end of the last argument to suppress the trailing newline that .Ic echo would otherwise output. .It Li \ef Output a form feed. .It Li \en Output a newline character. .It Li \er Output a carriage return. .It Li \et Output a (horizontal) tab character. .It Li \ev Output a vertical tab. .It Li \e0 Ns Ar digits Output the character whose value is given by zero to three octal digits. If there are zero digits, a nul character is output. .It Li \e\e Output a backslash. .El .Pp All other backslash sequences elicit undefined behaviour. .It eval Ar string ... Concatenate all the arguments with spaces. Then re-parse and execute the command. .It exec Op Ar command arg ... Unless command is omitted, the shell process is replaced with the specified program (which must be a real program, not a shell builtin or function). Any redirections on the .Ic exec command are marked as permanent, so that they are not undone when the .Ic exec command finishes. .It exit Op Ar exitstatus Terminate the shell process. If .Ar exitstatus is given it is used as the exit status of the shell; otherwise the exit status of the preceding command is used. .It export Ar name ... .It export Fl p The specified names are exported so that they will appear in the environment of subsequent commands. The only way to un-export a variable is to unset it. The shell allows the value of a variable to be set at the same time it is exported by writing .Pp .Dl export name=value .Pp With no arguments the export command lists the names of all exported variables. With the .Fl p option specified the output will be formatted suitably for non-interactive use. .It Xo fc Op Fl e Ar editor .Op Ar first Op Ar last .Xc .It Xo fc Fl l .Op Fl nr .Op Ar first Op Ar last .Xc .It Xo fc Fl s Op Ar old=new .Op Ar first .Xc The .Ic fc builtin lists, or edits and re-executes, commands previously entered to an interactive shell. .Bl -tag -width 5n .It Fl e No editor Use the editor named by editor to edit the commands. The editor string is a command name, subject to search via the .Ev PATH variable. The value in the .Ev FCEDIT variable is used as a default when .Fl e is not specified. If .Ev FCEDIT is null or unset, the value of the .Ev EDITOR variable is used. If .Ev EDITOR is null or unset, .Xr ed 1 is used as the editor. .It Fl l No (ell) List the commands rather than invoking an editor on them. The commands are written in the sequence indicated by the first and last operands, as affected by .Fl r , with each command preceded by the command number. .It Fl n Suppress command numbers when listing with -l. .It Fl r Reverse the order of the commands listed (with .Fl l ) or edited (with neither .Fl l nor .Fl s ) . .It Fl s Re-execute the command without invoking an editor. .It first .It last Select the commands to list or edit. The number of previous commands that can be accessed are determined by the value of the .Ev HISTSIZE variable. The value of first or last or both are one of the following: .Bl -tag -width 5n .It [+]number A positive number representing a command number; command numbers can be displayed with the .Fl l option. .It Fl number A negative decimal number representing the command that was executed number of commands previously. For example, \-1 is the immediately previous command. .El .It string A string indicating the most recently entered command that begins with that string. If the old=new operand is not also specified with .Fl s , the string form of the first operand cannot contain an embedded equal sign. .El .Pp The following environment variables affect the execution of fc: .Bl -tag -width HISTSIZE .It Ev FCEDIT Name of the editor to use. .It Ev HISTSIZE The number of previous commands that are accessible. .El .It fg Op Ar job Move the specified job or the current job to the foreground. .It getopts Ar optstring var The .Tn POSIX .Ic getopts command, not to be confused with the .Em Bell Labs -derived .Xr getopt 1 . .Pp The first argument should be a series of letters, each of which may be optionally followed by a colon to indicate that the option requires an argument. The variable specified is set to the parsed option. .Pp The .Ic getopts command deprecates the older .Xr getopt 1 utility due to its handling of arguments containing whitespace. .Pp The .Ic getopts builtin may be used to obtain options and their arguments from a list of parameters. When invoked, .Ic getopts places the value of the next option from the option string in the list in the shell variable specified by .Va var and its index in the shell variable .Ev OPTIND . When the shell is invoked, .Ev OPTIND is initialized to 1. For each option that requires an argument, the .Ic getopts builtin will place it in the shell variable .Ev OPTARG . If an option is not allowed for in the .Va optstring , then .Ev OPTARG will be unset. .Pp .Va optstring is a string of recognized option letters (see .Xr getopt 3 ) . If a letter is followed by a colon, the option is expected to have an argument which may or may not be separated from it by white space. If an option character is not found where expected, .Ic getopts will set the variable .Va var to a .Dq \&? ; .Ic getopts will then unset .Ev OPTARG and write output to standard error. By specifying a colon as the first character of .Va optstring all errors will be ignored. .Pp After the last option .Ic getopts will return a non-zero value and set .Va var to .Dq \&? . .Pp The following code fragment shows how one might process the arguments for a command that can take the options .Op a and .Op b , and the option .Op c , which requires an argument. .\".Pp .Bd -literal -offset indent while getopts abc: f do case $f in a | b) flag=$f;; c) carg=$OPTARG;; \\?) echo $USAGE; exit 1;; esac done shift `expr $OPTIND - 1` .Ed .Pp This code will accept any of the following as equivalent: .\".Pp .Bd -literal -offset indent cmd \-acarg file file cmd \-a \-c arg file file cmd \-carg -a file file cmd \-a \-carg \-\- file file .Ed .It hash Fl rv Ar command ... The shell maintains a hash table which remembers the locations of commands. With no arguments whatsoever, the .Ic hash command prints out the contents of this table. Entries which have not been looked at since the last .Ic cd command are marked with an asterisk; it is possible for these entries to be invalid. .Pp With arguments, the .Ic hash command removes the specified commands from the hash table (unless they are functions) and then locates them. With the .Fl v option, hash prints the locations of the commands as it finds them. The .Fl r option causes the hash command to delete all the entries in the hash table except for functions. .It pwd Op Fl LP builtin command remembers what the current directory is rather than recomputing it each time. This makes it faster. However, if the current directory is renamed, the builtin version of .Ic pwd will continue to print the old name for the directory. The .Fl P option causes the physical value of the current working directory to be shown, that is, all symbolic links are resolved to their respective values. The .Fl L option turns off the effect of any preceding .Fl P options. .It Xo read Op Fl p Ar prompt .Op Fl r .Ar variable .Op Ar ... .Xc The prompt is printed if the .Fl p option is specified and the standard input is a terminal. Then a line is read from the standard input. The trailing newline is deleted from the line and the line is split as described in the section on word splitting above, and the pieces are assigned to the variables in order. At least one variable must be specified. If there are more pieces than variables, the remaining pieces (along with the characters in .Ev IFS that separated them) are assigned to the last variable. If there are more variables than pieces, the remaining variables are assigned the null string. The .Ic read builtin will indicate success unless EOF is encountered on input, in which case failure is returned. .Pp By default, unless the .Fl r option is specified, the backslash .Dq \e acts as an escape character, causing the following character to be treated literally. If a backslash is followed by a newline, the backslash and the newline will be deleted. .It readonly Ar name ... .It readonly Fl p The specified names are marked as read only, so that they cannot be subsequently modified or unset. The shell allows the value of a variable to be set at the same time it is marked read only by writing .Pp .Dl readonly name=value .Pp With no arguments the readonly command lists the names of all read only variables. With the .Fl p option specified the output will be formatted suitably for non-interactive use. .\".Pp .It Xo printf Ar format .Op Ar arguments ... .Xc .Ic printf formats and prints its arguments, after the first, under control of the .Ar format . The .Ar format is a character string which contains three types of objects: plain characters, which are simply copied to standard output, character escape sequences which are converted and copied to the standard output, and format specifications, each of which causes printing of the next successive .Ar argument . .Pp The .Ar arguments after the first are treated as strings if the corresponding format is either .Cm b , .Cm c or .Cm s ; otherwise it is evaluated as a C constant, with the following extensions: .Pp .Bl -bullet -offset indent -compact .It A leading plus or minus sign is allowed. .It If the leading character is a single or double quote, the value is the .Tn ASCII code of the next character. .El .Pp The format string is reused as often as necessary to satisfy the .Ar arguments . Any extra format specifications are evaluated with zero or the null string. .Pp Character escape sequences are in backslash notation as defined in .St -ansiC . The characters and their meanings are as follows: .Bl -tag -width Ds -offset indent .It Cm \ea Write a \*[Lt]bell\*[Gt] character. .It Cm \eb Write a \*[Lt]backspace\*[Gt] character. .It Cm \ef Write a \*[Lt]form-feed\*[Gt] character. .It Cm \en Write a \*[Lt]new-line\*[Gt] character. .It Cm \er Write a \*[Lt]carriage return\*[Gt] character. .It Cm \et Write a \*[Lt]tab\*[Gt] character. .It Cm \ev Write a \*[Lt]vertical tab\*[Gt] character. .It Cm \e\e Write a backslash character. .It Cm \e Ns Ar num Write an 8\-bit character whose .Tn ASCII value is the 1\-, 2\-, or 3\-digit octal number .Ar num . .El .Pp Each format specification is introduced by the percent character (``%''). The remainder of the format specification includes, in the following order: .Bl -tag -width Ds .It "Zero or more of the following flags:" .Bl -tag -width Ds .It Cm # A `#' character specifying that the value should be printed in an ``alternative form''. For .Cm b , .Cm c , .Cm d , and .Cm s formats, this option has no effect. For the .Cm o format the precision of the number is increased to force the first character of the output string to a zero. For the .Cm x .Pq Cm X format, a non-zero result has the string .Li 0x .Pq Li 0X prepended to it. For .Cm e , .Cm E , .Cm f , .Cm g , and .Cm G formats, the result will always contain a decimal point, even if no digits follow the point (normally, a decimal point only appears in the results of those formats if a digit follows the decimal point). For .Cm g and .Cm G formats, trailing zeros are not removed from the result as they would otherwise be. .It Cm \&\- A minus sign `\-' which specifies .Em left adjustment of the output in the indicated field; .It Cm \&+ A `+' character specifying that there should always be a sign placed before the number when using signed formats. .It Sq \&\ \& A space specifying that a blank should be left before a positive number for a signed format. A `+' overrides a space if both are used; .It Cm \&0 A zero `0' character indicating that zero-padding should be used rather than blank-padding. A `\-' overrides a `0' if both are used; .El .It "Field Width:" An optional digit string specifying a .Em field width ; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width); .It Precision : An optional period, .Sq Cm \&.\& , followed by an optional digit string giving a .Em precision which specifies the number of digits to appear after the decimal point, for .Cm e and .Cm f formats, or the maximum number of bytes to be printed from a string .Sm off .Pf ( Cm b .Sm on and .Cm s formats); if the digit string is missing, the precision is treated as zero; .It Format : A character which indicates the type of format to use (one of .Cm diouxXfwEgGbcs ) . .El .Pp A field width or precision may be .Sq Cm \&* instead of a digit string. In this case an .Ar argument supplies the field width or precision. .Pp The format characters and their meanings are: .Bl -tag -width Fl .It Cm diouXx The .Ar argument is printed as a signed decimal (d or i), unsigned octal, unsigned decimal, or unsigned hexadecimal (X or x), respectively. .It Cm f The .Ar argument is printed in the style .Sm off .Pf [\-]ddd Cm \&. No ddd .Sm on where the number of d's after the decimal point is equal to the precision specification for the argument. If the precision is missing, 6 digits are given; if the precision is explicitly 0, no digits and no decimal point are printed. .It Cm eE The .Ar argument is printed in the style .Sm off .Pf [\-]d Cm \&. No ddd Cm e No \*(Pmdd .Sm on where there is one digit before the decimal point and the number after is equal to the precision specification for the argument; when the precision is missing, 6 digits are produced. An upper-case E is used for an `E' format. .It Cm gG The .Ar argument is printed in style .Cm f or in style .Cm e .Pq Cm E whichever gives full precision in minimum space. .It Cm b Characters from the string .Ar argument are printed with backslash-escape sequences expanded. .br The following additional backslash-escape sequences are supported: .Bl -tag -width Ds .It Cm \ec Causes .Nm to ignore any remaining characters in the string operand containing it, any remaining string operands, and any additional characters in the format operand. .It Cm \e0 Ns Ar num Write an 8\-bit character whose .Tn ASCII value is the 1\-, 2\-, or 3\-digit octal number .Ar num . .El .It Cm c The first character of .Ar argument is printed. .It Cm s Characters from the string .Ar argument are printed until the end is reached or until the number of bytes indicated by the precision specification is reached; if the precision is omitted, all characters in the string are printed. .It Cm \&% Print a `%'; no argument is used. .El .Pp In no case does a non-existent or small field width cause truncation of a field; padding takes place only if the specified field width exceeds the actual width. .It Xo set .Oo { .Fl options | Cm +options | Cm -- } .Oc Ar arg ... .Xc The .Ic set command performs three different functions. .Pp With no arguments, it lists the values of all shell variables. .Pp If options are given, it sets the specified option flags, or clears them as described in the section called .Sx Argument List Processing . As a special case, if the option is -o or +o and no argument is supplied, the shell prints the settings of all its options. If the option is -o, the settings are printed in a human-readable format; if the option is +o, the settings are printed in a format suitable for reinput to the shell to affect the same option settings. .Pp The third use of the set command is to set the values of the shell's positional parameters to the specified args. To change the positional parameters without changing any options, use .Dq -- as the first argument to set. If no args are present, the set command will clear all the positional parameters (equivalent to executing .Dq shift $# . ) .It shift Op Ar n Shift the positional parameters n times. A .Ic shift sets the value of .Va $1 to the value of .Va $2 , the value of .Va $2 to the value of .Va $3 , and so on, decreasing the value of .Va $# by one. If n is greater than the number of positional parameters, .Ic shift will issue an error message, and exit with return status 2. .It test Ar expression .It \&[ Ar expression Cm \&] The .Ic test utility evaluates the expression and, if it evaluates to true, returns a zero (true) exit status; otherwise it returns 1 (false). If there is no expression, test also returns 1 (false). .Pp All operators and flags are separate arguments to the .Ic test utility. .Pp The following primaries are used to construct expression: .Bl -tag -width Ar .It Fl b Ar file True if .Ar file exists and is a block special file. .It Fl c Ar file True if .Ar file exists and is a character special file. .It Fl d Ar file True if .Ar file exists and is a directory. .It Fl e Ar file True if .Ar file exists (regardless of type). .It Fl f Ar file True if .Ar file exists and is a regular file. .It Fl g Ar file True if .Ar file exists and its set group ID flag is set. .It Fl h Ar file True if .Ar file exists and is a symbolic link. .It Fl k Ar file True if .Ar file exists and its sticky bit is set. .It Fl n Ar string True if the length of .Ar string is nonzero. .It Fl p Ar file True if .Ar file is a named pipe .Po Tn FIFO Pc . .It Fl r Ar file True if .Ar file exists and is readable. .It Fl s Ar file True if .Ar file exists and has a size greater than zero. .It Fl t Ar file_descriptor True if the file whose file descriptor number is .Ar file_descriptor is open and is associated with a terminal. .It Fl u Ar file True if .Ar file exists and its set user ID flag is set. .It Fl w Ar file True if .Ar file exists and is writable. True indicates only that the write flag is on. The file is not writable on a read-only file system even if this test indicates true. .It Fl x Ar file True if .Ar file exists and is executable. True indicates only that the execute flag is on. If .Ar file is a directory, true indicates that .Ar file can be searched. .It Fl z Ar string True if the length of .Ar string is zero. .It Fl L Ar file True if .Ar file exists and is a symbolic link. This operator is retained for compatibility with previous versions of this program. Do not rely on its existence; use .Fl h instead. .It Fl O Ar file True if .Ar file exists and its owner matches the effective user id of this process. .It Fl G Ar file True if .Ar file exists and its group matches the effective group id of this process. .It Fl S Ar file True if .Ar file exists and is a socket. .It Ar file1 Fl nt Ar file2 True if .Ar file1 and .Ar file2 exist and .Ar file1 is newer than .Ar file2 . .It Ar file1 Fl ot Ar file2 True if .Ar file1 and .Ar file2 exist and .Ar file1 is older than .Ar file2 . .It Ar file1 Fl ef Ar file2 True if .Ar file1 and .Ar file2 exist and refer to the same file. .It Ar string True if .Ar string is not the null string. .It Ar \&s\&1 Cm \&= Ar \&s\&2 True if the strings .Ar \&s\&1 and .Ar \&s\&2 are identical. .It Ar \&s\&1 Cm \&!= Ar \&s\&2 True if the strings .Ar \&s\&1 and .Ar \&s\&2 are not identical. .It Ar \&s\&1 Cm \&\*[Lt] Ar \&s\&2 True if string .Ar \&s\&1 comes before .Ar \&s\&2 based on the ASCII value of their characters. .It Ar \&s\&1 Cm \&\*[Gt] Ar \&s\&2 True if string .Ar \&s\&1 comes after .Ar \&s\&2 based on the ASCII value of their characters. .It Ar \&n\&1 Fl \&eq Ar \&n\&2 True if the integers .Ar \&n\&1 and .Ar \&n\&2 are algebraically equal. .It Ar \&n\&1 Fl \&ne Ar \&n\&2 True if the integers .Ar \&n\&1 and .Ar \&n\&2 are not algebraically equal. .It Ar \&n\&1 Fl \> Ar \&n\&2 True if the integer .Ar \&n\&1 is algebraically greater than the integer .Ar \&n\&2 . .It Ar \&n\&1 Fl \&ge Ar \&n\&2 True if the integer .Ar \&n\&1 is algebraically greater than or equal to the integer .Ar \&n\&2 . .It Ar \&n\&1 Fl \< Ar \&n\&2 True if the integer .Ar \&n\&1 is algebraically less than the integer .Ar \&n\&2 . .It Ar \&n\&1 Fl \&le Ar \&n\&2 True if the integer .Ar \&n\&1 is algebraically less than or equal to the integer .Ar \&n\&2 . .El .Pp These primaries can be combined with the following operators: .Bl -tag -width Ar .It Cm \&! Ar expression True if .Ar expression is false. .It Ar expression1 Fl a Ar expression2 True if both .Ar expression1 and .Ar expression2 are true. .It Ar expression1 Fl o Ar expression2 True if either .Ar expression1 or .Ar expression2 are true. .It Cm \&( Ns Ar expression Ns Cm \&) True if expression is true. .El .Pp The .Fl a operator has higher precedence than the .Fl o operator. .It times Print the accumulated user and system times for the shell and for processes run from the shell. The return status is 0. .It Xo trap .Op Ar action Ar signal ... .Xc Cause the shell to parse and execute action when any of the specified signals are received. The signals are specified by signal number or as the name of the signal. If .Ar signal is .Li 0 or .Li EXIT , the action is executed when the shell exits. .Ar action may be empty .Li ( "''" ) , which causes the specified signals to be ignored. With .Ar action omitted or set to `-' the specified signals are set to their default action. When the shell forks off a subshell, it resets trapped (but not ignored) signals to the default action. The .Ic trap command has no effect on signals that were ignored on entry to the shell. .Ic trap without any arguments cause it to write a list of signals and their associated action to the standard output in a format that is suitable as an input to the shell that achieves the same trapping results. .Pp Examples: .Pp .Dl trap .Pp List trapped signals and their corresponding action .Pp .Dl trap '' INT QUIT tstp 30 .Pp Ignore signals INT QUIT TSTP USR1 .Pp .Dl trap date INT .Pp Print date upon receiving signal INT .It type Op Ar name ... Interpret each name as a command and print the resolution of the command search. Possible resolutions are: shell keyword, alias, shell builtin, command, tracked alias and not found. For aliases the alias expansion is printed; for commands and tracked aliases the complete pathname of the command is printed. .It ulimit Xo .Op Fl H \*(Ba Fl S .Op Fl a \*(Ba Fl tfdscmlpnv Op Ar value .Xc Inquire about or set the hard or soft limits on processes or set new limits. The choice between hard limit (which no process is allowed to violate, and which may not be raised once it has been lowered) and soft limit (which causes processes to be signaled but not necessarily killed, and which may be raised) is made with these flags: .Bl -tag -width Fl .It Fl H set or inquire about hard limits .It Fl S set or inquire about soft limits. If neither .Fl H nor .Fl S is specified, the soft limit is displayed or both limits are set. If both are specified, the last one wins. .El .Pp The limit to be interrogated or set, then, is chosen by specifying any one of these flags: .Bl -tag -width Fl .It Fl a show all the current limits .It Fl t show or set the limit on CPU time (in seconds) .It Fl f show or set the limit on the largest file that can be created (in 512-byte blocks) .It Fl d show or set the limit on the data segment size of a process (in kilobytes) .It Fl s show or set the limit on the stack size of a process (in kilobytes) .It Fl c show or set the limit on the largest core dump size that can be produced (in 512-byte blocks) .It Fl m show or set the limit on the total physical memory that can be in use by a process (in kilobytes) .It Fl l show or set the limit on how much memory a process can lock with .Xr mlock 2 (in kilobytes) .It Fl p show or set the limit on the number of processes this user can have at one time .It Fl n show or set the limit on the number files a process can have open at once .It Fl v show or set the limit on the total virtual memory that can be in use by a process (in kilobytes) .It Fl r show or set the limit on the real-time scheduling priority of a process .El .Pp If none of these is specified, it is the limit on file size that is shown or set. If value is specified, the limit is set to that number; otherwise the current limit is displayed. .Pp Limits of an arbitrary process can be displayed or set using the .Xr sysctl 8 utility. .\".Pp .It umask Op Ar mask Set the value of umask (see .Xr umask 2 ) to the specified octal value. If the argument is omitted, the umask value is printed. .It unalias Xo .Op Fl a .Op Ar name .Xc If .Ar name is specified, the shell removes that alias. If .Fl a is specified, all aliases are removed. .It unset Xo .Op Fl fv .Ar name ... .Xc The specified variables and functions are unset and unexported. If .Fl f or .Fl v is specified, the corresponding function or variable is unset, respectively. If a given name corresponds to both a variable and a function, and no options are given, only the variable is unset. .It wait Op Ar job Wait for the specified job to complete and return the exit status of the last process in the job. If the argument is omitted, wait for all jobs to complete and return an exit status of zero. .El .Ss Command Line Editing When .Nm is being used interactively from a terminal, the current command and the command history (see .Ic fc in .Sx Builtins ) can be edited using vi-mode command-line editing. This mode uses commands, described below, similar to a subset of those described in the vi man page. The command .Ql set -o vi enables vi-mode editing and places sh into vi insert mode. With vi-mode enabled, sh can be switched between insert mode and command mode. It is similar to vi: typing .Aq ESC enters vi command mode. Hitting .Aq return while in command mode will pass the line to the shell. .Sh EXIT STATUS Errors that are detected by the shell, such as a syntax error, will cause the shell to exit with a non-zero exit status. If the shell is not an interactive shell, the execution of the shell file will be aborted. Otherwise the shell will return the exit status of the last command executed, or if the exit builtin is used with a numeric argument, it will return the argument. .Sh ENVIRONMENT .Bl -tag -width MAILCHECK .It Ev HOME Set automatically by .Xr login 1 from the user's login directory in the password file .Pq Xr passwd 4 . This environment variable also functions as the default argument for the cd builtin. .It Ev PATH The default search path for executables. See the above section .Sx Path Search . .It Ev CDPATH The search path used with the cd builtin. .It Ev MAIL The name of a mail file, that will be checked for the arrival of new mail. Overridden by .Ev MAILPATH . .It Ev MAILCHECK The frequency in seconds that the shell checks for the arrival of mail in the files specified by the .Ev MAILPATH or the .Ev MAIL file. If set to 0, the check will occur at each prompt. .It Ev MAILPATH A colon .Dq \&: separated list of file names, for the shell to check for incoming mail. This environment setting overrides the .Ev MAIL setting. There is a maximum of 10 mailboxes that can be monitored at once. .It Ev PS1 The primary prompt string, which defaults to .Dq $\ , unless you are the superuser, in which case it defaults to .Dq #\ . .It Ev PS2 The secondary prompt string, which defaults to .Dq \*[Gt]\ . .It Ev PS4 Output before each line when execution trace (set -x) is enabled, defaults to .Dq +\ . .It Ev IFS Input Field Separators. This is normally set to .Aq space , .Aq tab , and .Aq newline . See the .Sx White Space Splitting section for more details. .It Ev TERM The default terminal setting for the shell. This is inherited by children of the shell, and is used in the history editing modes. .It Ev HISTSIZE The number of lines in the history buffer for the shell. .It Ev PWD The logical value of the current working directory. This is set by the .Ic cd command. .It Ev OLDPWD The previous logical value of the current working directory.

This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. 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, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. 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 you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' 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. Running 'configure' might take a while. 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, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. 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. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. 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 can use 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 '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer 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. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' 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. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= 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'. 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. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS 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 machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. 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. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--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. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. '--no-create' '-n' Run the configure checks, but stop before creating any output files. 'configure' also accepts some other, not widely useful, options. Run 'configure --help' for more details.
