exit ends the shell. If there is an expression, the value of the expression is the exit
status of the shell.
The value of expression should be between 0 and 255. For values outside this
range, the exit status will be the least significant 8 bits of the value of the
expression. The EXIT trap is raised by the exit command, unless exit is being
called from inside an EXIT trap.
If you have a shell background job running, you cannot exit from the shell until it
completes. However, you can switch to subcommand mode and exit.
exit in the tcsh shell
The shell exits either with the value of the specified expression or, without
expression, with the value of the status variable. The value of expression should be
between 0 and 255. See “tcsh — Invoke a C shell” on page 626.
exit is a special built-in shell command.
exit uses the following localization environment variables:
v LANG
v LC_ALL
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.
exit returns the value of the arithmetic expression specified by the expression
argument to the parent process as the exit status of the shell. If you omit
expression, exit returns the exit status of the last command run.
The exit() ANSI C function, the _exit callable service, and the _exit() POSIX C
function are unrelated to the exit shell command.
