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 pos-
       sibly 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.
