====== GNU screen ======

==== Intro ====

Screen is a text-based program usually described as a window manager or terminal multiplexer.  While it does a great many things, its two biggest features are its detachability and its multiplexing.  The detachability means that you can run programs from within screen, detach and logout, then log in later, reattach, and the programs will still be there.  The multiplexing means that you can have multiple programs running within a single screen session, each within its own window.  You can display multiple windows at once, or just switch between them, even if you only have a single terminal window to use. 

For more info on what screen can do, see the [[detailed description]].

==== FAQ ====

First stop for any questions should be the [[FAQ]].

==== Where to Get It ====

The official GNU screen page is [[http://www.gnu.org/software/screen/]].  The canonical repository for the screen source is [[ftp://ftp.gnu.org/gnu/screen/]].  There are no official precompiled binaries, but your system vendor may have them available.

The current development sources may also be had from the [[https://savannah.gnu.org/git/?group=screen|git repository]]; or you may [[http://git.savannah.gnu.org/gitweb/?p=screen.git|browse them online]]. Note that building from the repository sources may require additional tools, such as GNU Autoconf.

==== Discussion ====

The user discussion mailing list can be found at [[http://lists.gnu.org/mailman/listinfo/screen-users]].  There is an IRC channel on [[https://libera.chat/|Libera]] (irc.libera.chat) named ''#screen''.

==== Bugs ====

See the [[bugtracker]] page for information on submitting or searching for bug reports regarding GNU Screen. If you're unsure whether something is a bug, feel free to ask about it on the mailing lists or in the IRC channel.

To that end, I'd like comments on which ones are useful (or not useful), either in comments left on this page or in [[phil_g+screen@pobox.com|email to me]].  <PMG>//]
