exit

Exit shell with success status

$ exit

$ exit [1]

$ set -e; exit

exit [status]

exit is a shell builtin that terminates the current shell or script. An optional exit status is passed to the parent process; 0 conventionally indicates success.
In scripts, exit immediately stops execution. In interactive shells, it closes the session. The exit status is available to the parent process via $? in shell scripts.
Exit codes have conventional meanings: 0 for success, 1 for general errors, 2 for misuse, 126-127 for execution issues.

STATUS

Exit status code (0-255). 0 indicates success.

Non-zero exits may trigger set -e termination. Status limited to 0-255. Subshells have separate exit. Traps may run before actual exit.

exit is a fundamental POSIX shell builtin, present since the original Bourne shell. Its semantics are consistent across all Unix shells.
