exit [ n ]
       Exit  the shell with the exit status specified by an arithmetic ex-
       pression 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.
