# NAME

exit - terminate this program

# SYNOPSIS

exit EXPR

exit

# DESCRIPTION

Evaluates EXPR and exits immediately with that value. Example:

        $ans = <STDIN>;
        exit 0 if $ans =~ /^[Xx]/;

See also `die`. If EXPR is omitted, exits with `0` status. The only universally recognized values for EXPR are `0` for success and `1` for error; other values are subject to interpretation depending on the environment in which the Perl program is running. For example, exiting 69 (EX_UNAVAILABLE) from a sendmail incoming-mail filter will cause the mailer to return the item undelivered, but that's not true everywhere.

Don't use `exit` to abort a subroutine if there's any chance that someone might want to trap whatever error happened. Use `die` instead, which can be trapped by an `eval`.

The `exit()` function does not always exit immediately. It calls any defined `END` routines first, but these `END` routines may not themselves abort the exit. Likewise any object destructors that need to be called are called before the real exit. If this is a problem, you can call `POSIX:_exit($status)` to avoid END and destructor processing. See the perlmod manpage for details.
