MPE/iX Shell and Utilities Reference Manual, Vol 1

exit(1) MPE/iX Shell and Utilities exit(1)

NAME

exit — exit from the shell

SYNOPSIS

exit [expression]

DESCRIPTION

exit terminates the shell.

On a POSIX-compliant system, the value of expression should be between 0 and 255. The

EXIT trap is raised by the exit command, unless exit is being invoked inside an EXIT

trap.

DIAGNOSTICS

exit returns the value of the arithmetic expression to the parent process as the exit status of

the shell. If you omit expression, it returns the exit status of the last command executed.

Messages

Because this utility is built into the

MPE/iX Shell, see the sh(1) man page for a complete list of

error messages that you may receive when using it.

PORTABILITY

POSIX.2. x/OPEN Portability Guide 4.0. All UNIX systems.

Allowing an expression rather than just a number is an extension found in the KornShell.

NOTE

This is a special built-in command of the shell.

MPE/iX NOTES

If you are using the

MPE/iX Shell under the MPE/iX CI, remember that using the exit command

at the shell’s root level does not log you off the system but merely returns you to the MPE/iX CI.
