.. _cmd-suspend:
suspend - suspend the current shell
===================================
Synopsis
--------
::
suspend [--force]
Description
-----------
``suspend`` suspends execution of the current shell by sending it a SIGTSTP signal, returning to the controlling process. It can be resumed later by sending it a SIGCONT. In order to prevent suspending a shell that doesn't have a controlling process, it will not suspend the shell if it is a login shell. This requirement is bypassed if the ``--force`` option is given or the shell is not interactive.
