subsequent assignment.
% return [ n ] Causes a shell function to return to the invoking script with the return status specified
by n.Ifn is omitted, the return status is that of the last command executed. Only the
low 8 bits of n are passed back to the caller. If
return is invoked while not in a func-
tion or executing a script by the
.
(dot) built-in command, it has the same effect as an
exit command.
set [ ±aefhkmnopstuvx | ±o option ] ... [ ±A name ][arg ... ]
The following options are used for this command:
-A Array assignment. Unset the variable name and assign values sequentially from
the list arg.If+A is used, the variable name is not unset first.
-a All subsequent defined parameters are automatically exported.
-e If the shell is non-interactive and if a command fails, execute the
ERR trap, if
set, and exit immediately. This mode is disabled while reading profiles.
-f Disables file name generation.
-h Each command whose name is an identifier becomes a tracked alias when first
encountered.
-k All parameter assignment arguments (not just those that precede the command
name) are placed in the environment for a command.
-m Background jobs are run in a separate process group and a line is printed upon
completion. The exit status of background jobs is reported in a completion mes-
sage. This option is turned on automatically for interactive shells.
-n Read commands and check them for syntax errors, but do not execute them. The
-n option is ignored for interactive shells.
-o The -o argument takes any of several option names, but only one option can be
specified with each -o option. If none is supplied, the current option settings
are printed. The -o argument option names follow:
allexport Same as -a.
bgnice All background jobs are run at a lower priority.
errexit Same as -e.
emacs Activates an emacs-style in-line editor for command entry.
gmacs Activates a gmacs-style in-line editor for command entry.
ignoreeof The shell does not exit on end-of-file. The command exit
must be used.
keyword Same as -k.
markdirs All directory names resulting from file name generation have
a trailing / appended.
monitor Same as -m.
noclobber Prevents redirection > from truncating existing regular files.
Requires >| to truncate a file when turned on.
noexec Same as -n.
noglob Same as -f.
nolog Do not save function definitions in history file.
nounset Same as -u.
privileged Same as -p.
verbose Same as -v.
trackall Same as -h.
vi Activates the insert mode of a vi-style in-line editor until
you press the ESC key which puts you in move mode. A
return sends the line.
viraw Each character is processed as it is typed in vi mode.
xtrace Same as -x.
-p Disables processing of the $HOME/.profile file and uses the file
/etc/suid_profile instead of the ENV file. This mode is on whenever the
effective uid (gid) is not equal to the real uid (gid). Turning this off causes the
effective uid and gid to be set to the real uid and gid.
-s Sort the positional parameters.
-t Exit after reading and executing one command.
-u Treat unset parameters as an error when substituting.
-v Print shell input lines as they are read.
