'''GNU Screen''' is an [[open-source software|open-source]] [[Computer terminal|terminal]] [[multiplex]]er developed by the [[GNU]] Project.  It allows a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session.  It is useful for dealing with multiple programs from the [[Command line interface|command line]], and for separating programs from the [[Unix shell|shell]] that started the program.

==Benefits==
GNU Screen is akin to the text version of graphical [[window manager]]s.

On [[Unix-like]] [[operating system]]s, [[Graphical user interface|GUI]] terminal emulators like [[Gnome Terminal]] and [[Konsole]] provide the ability to open multiple terminals. There are many reasons to use screen over these terminals.

#It is terminal agnostic, for terminals that were implemented correctly.
#The session can be detached and reattached, making migration between locations like work and home simple, without requiring bandwidth-hogging remote desktop protocols, like [[Virtual Network Computing|VNC]]. 
#It can notify the user of activity or inactivity in terminals, permitting notification of events like the end of a [[compilation]], or activity in an [[Internet Relay Chat|IRC]] application.
#It has scroll-back capabilities that are set independently from the terminal, ensuring that your preferences work regardless of the terminal you are using at each location.
#Multiple users can join into one screen session, with read-only or full access, permitting [[collaboration]] in many forms.
#It can split the screen, again regardless of the compliant terminal.
#It provides these features with or without the [[X Window System]] being available.
