Synopsis

.. synopsis::

exec COMMAND

Description

.. only:: builder_man

      NOTE: This page documents the fish builtin ``exec``.
      To see the documentation on any non-fish versions, use ``command man exec``.

exec replaces the currently running shell with a new command. On successful completion, exec never returns. exec cannot be used inside a pipeline.

The --help or -h option displays help about using this command.

Example

exec emacs starts up the emacs text editor, and exits fish. When emacs exits, the session will terminate.
