Exit the shell.

Source: src/execution/builtins.f90:248-327

Synopsis

exit [n]

Description

Terminates the shell with exit status n. If n is omitted, the exit status is that of the last command executed. If n is not a valid integer, the exit status is 2.

Before exiting, fortsh executes any EXIT trap that has been registered with trap.

Arguments

Behavior

1. If an EXIT trap is set, it runs first (exactly once)
2. The shell's main loop terminates
3. The process exits with the given status code

exit          # Exit with last command's status
exit 0        # Exit successfully
exit 1        # Exit with failure
exit 42       # Exit with custom code

Exit Status

Examples

# Exit on error
if [[ ! -f config ]]; then
    echo "Config missing" >&2
    exit 1
fi

# Cleanup before exit using trap
cleanup() {
    rm -f "$tmpfile"
}
trap cleanup EXIT

tmpfile=$(mktemp)
# Work with tmpfile...
exit 0    # cleanup runs automatically
