exit [ n ]
       Exit  the  shell with the exit status specified by an arithmetic
       expression n; if none is specified, use the exit status from the
       last  command  executed.   An  EOF condition will also cause the
       shell to exit, unless the IGNORE_EOF option is set.

       See notes at the end of the section JOBS in zshmisc(1) for  some
       possibly unexpected interactions of the exit command with jobs.

bye    Same as exit.

logout [ n ]
       Same as exit, except that it only works in a login shell.
