EXIT(P) POSIX Programmer's Manual EXIT(P)
NAME
exit - cause the shell to exit
SYNOPSIS
exit [n]
DESCRIPTION
The exit utility shall cause the shell to exit with the exit status specified by the unsigned decimal integer n. If n is specified, but
its value is not between 0 and 255 inclusively, the exit status is undefined.
A trap on EXIT shall be executed before the shell terminates, except when the exit utility is invoked in that trap itself, in which case
the shell shall exit immediately.
OPTIONS
None.
OPERANDS
See the DESCRIPTION.
STDIN
Not used.
INPUT FILES
None.
ENVIRONMENT VARIABLES
None.
ASYNCHRONOUS EVENTS
Default.
STDOUT
Not used.
STDERR
The standard error shall be used only for diagnostic messages.
OUTPUT FILES
None.
EXTENDED DESCRIPTION
None.
EXIT STATUS
The exit status shall be n, if specified. Otherwise, the value shall be the exit value of the last command executed, or zero if no command
was executed. When exit is executed in a trap action, the last command is considered to be the command that executed immediately preceding
the trap action.
CONSEQUENCES OF ERRORS
Default.
The following sections are informative.
APPLICATION USAGE
None.
EXAMPLES
Exit with a true value:
exit 0
Exit with a false value:
exit 1
RATIONALE
As explained in other sections, certain exit status values have been reserved for special uses and should be used by applications only for
those purposes:
126 A file to be executed was found, but it was not an executable utility.
127 A utility to be executed was not found.
>128 A command was interrupted by a signal.
FUTURE DIRECTIONS
None.
