Define or display aliases. Without arguments, `alias' prints the list of aliases in the reusable form `alias NAME=VALUE' on standard output. Otherwise, an alias is defined for each NAME whose VALUE is given. A trailing space in VALUE causes the next word to be checked for alias substitution when the alias is expanded. Options: -p print all defined aliases in a reusable format Exit Status: alias returns true unless a NAME is supplied for which no alias has been defined.

Set Readline key bindings and variables. Bind a key sequence to a Readline function or a macro, or set a Readline variable. The non-option argument syntax is equivalent to that found in ~/.inputrc, but must be passed as a single argument: e.g., bind '"\C-x\C-r": re-read-init-file'. Options: -m keymap Use KEYMAP as the keymap for the duration of this command. Acceptable keymap names are emacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, vi-command, and vi-insert. -l List names of functions. -P List function names and bindings. -p List functions and bindings in a form that can be reused as input. -S List key sequences that invoke macros and their values -s List key sequences that invoke macros and their values in a form that can be reused as input. -V List variable names and values -v List variable names and values in a form that can be reused as input. -q function-name Query about which keys invoke the named function. -u function-name Unbind all keys which are bound to the named function. -r keyseq Remove the binding for KEYSEQ. -f filename Read key bindings from FILENAME. -x keyseq:shell-command Cause SHELL-COMMAND to be executed when KEYSEQ is entered. -X List key sequences bound with -x and associated commands in a form that can be reused as input. Exit Status: bind returns 0 unless an unrecognized option is given or an error occurs.

Change the shell working directory. Change the current directory to DIR. The default DIR is the value of the HOME shell variable. The variable CDPATH defines the search path for the directory containing DIR. Alternative directory names in CDPATH are separated by a colon (:). A null directory name is the same as the current directory. If DIR begins with a slash (/), then CDPATH is not used. If the directory is not found, and the shell option `cdable_vars' is set, the word is assumed to be a variable name. If that variable has a value, its value is used for DIR. Options: -L force symbolic links to be followed: resolve symbolic links in DIR after processing instances of `..' -P use the physical directory structure without following symbolic links: resolve symbolic links in DIR before processing instances of `..' -e if the -P option is supplied, and the current working directory cannot be determined successfully, exit with a non-zero status -@ on systems that support it, present a file with extended attributes as a directory containing the file attributes The default is to follow symbolic links, as if `-L' were specified. `..' is processed by removing the immediately previous pathname component back to a slash or the beginning of DIR. Exit Status: Returns 0 if the directory is changed, and if $PWD is set successfully when -P is used; non-zero otherwise.

Print the name of the current working directory. Options: -L print the value of $PWD if it names the current working directory -P print the physical directory, without any symbolic links By default, `pwd' behaves as if `-L' were specified. Exit Status: Returns 0 unless an invalid option is given or the current directory cannot be read.

Execute a simple command or display information about commands. Runs COMMAND with ARGS suppressing shell function lookup, or display information about the specified COMMANDs. Can be used to invoke commands on disk when a function with the same name exists. Options: -p use a default value for PATH that is guaranteed to find all of the standard utilities -v print a description of COMMAND similar to the `type' builtin -V print a more verbose description of each COMMAND Exit Status: Returns exit status of COMMAND, or failure if COMMAND is not found.

Set variable values and attributes. Declare variables and give them attributes. If no NAMEs are given, display the attributes and values of all variables. Options: -f restrict action or display to function names and definitions -F restrict display to function names only (plus line number and source file when debugging) -g create global variables when used in a shell function; otherwise ignored -p display the attributes and value of each NAME Options which set attributes: -a to make NAMEs indexed arrays (if supported) -A to make NAMEs associative arrays (if supported) -i to make NAMEs have the `integer' attribute -l to convert NAMEs to lower case on assignment -n make NAME a reference to the variable named by its value -r to make NAMEs readonly -t to make NAMEs have the `trace' attribute -u to convert NAMEs to upper case on assignment -x to make NAMEs export Using `+' instead of `-' turns off the given attribute. Variables with the integer attribute have arithmetic evaluation (see the `let' command) performed when the variable is assigned a value. When used in a function, `declare' makes NAMEs local, as with the `local' command. The `-g' option suppresses this behavior. Exit Status: Returns success unless an invalid option is supplied or a variable assignment error occurs.

Replace the shell with the given command. Execute COMMAND, replacing this shell with the specified program. ARGUMENTS become the arguments to COMMAND. If COMMAND is not specified, any redirections take effect in the current shell. Options: -a name pass NAME as the zeroth argument to COMMAND -c execute COMMAND with an empty environment -l place a dash in the zeroth argument to COMMAND If the command cannot be executed, a non-interactive shell exits, unless the shell option `execfail' is set.

Send a signal to a job. Send the processes identified by PID or JOBSPEC the signal named by SIGSPEC or SIGNUM. If neither SIGSPEC nor SIGNUM is present, then SIGTERM is assumed. Options: -s sig SIG is a signal name -n sig SIG is a signal number -l list the signal names; if arguments follow `-l' they are assumed to be signal numbers for which names should be listed -L synonym for -l Kill is a shell builtin for two reasons: it allows job IDs to be used instead of process IDs, and allows processes to be killed if the limit on processes that you can create is reached. Exit Status: Returns success unless an invalid option is given or an error occurs.

Read a line from the standard input and split it into fields. Reads a single line from the standard input, or from file descriptor FD if the -u option is supplied. The line is split into fields as with word splitting, and the first word is assigned to the first NAME, the second word to the second NAME, and so on, with any leftover words assigned to the last NAME. Only the characters found in $IFS are recognized as word delimiters. If no NAMEs are supplied, the line read is stored in the REPLY variable. Options: -a array assign the words read to sequential indices of the array variable ARRAY, starting at zero -d delim continue until the first character of DELIM is read, rather than newline -e use Readline to obtain the line in an interactive shell -i text use TEXT as the initial text for Readline -n nchars return after reading NCHARS characters rather than waiting for a newline, but honor a delimiter if fewer than NCHARS characters are read before the delimiter -N nchars return only after reading exactly NCHARS characters, unless EOF is encountered or read times out, ignoring any delimiter -p prompt output the string PROMPT without a trailing newline before attempting to read -r do not allow backslashes to escape any characters -s do not echo input coming from a terminal -t timeout time out and return failure if a complete line of input is not read within TIMEOUT seconds. The value of the TMOUT variable is the default timeout. TIMEOUT may be a fractional number. If TIMEOUT is 0, read returns immediately, without trying to read any data, returning success only if input is available on the specified file descriptor. The exit status is greater than 128 if the timeout is exceeded -u fd read from file descriptor FD instead of the standard input Exit Status: The return code is zero, unless end-of-file is encountered, read times out (in which case it's greater than 128), a variable assignment error occurs, or an invalid file descriptor is supplied as the argument to -u.
