exec - execute command in current process
=========================================
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.
