GNU Screen is a software application that can be used to multiplex several virtual consoles, allowing 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 a command line interface, and for separating programs from the Unix shell that started the program.
Released under the terms of version 3 or later of the GNU General Public License, GNU Screen is free software.

Features [edit]
GNU Screen can be thought of as a text version of graphical window managers, or as a way of putting virtual terminals into any login session. It is a wrapper that allows multiple text programs to run at the same time, and provides features that allow the user to use the programs within a single interface productively. This enables the following features: persistence, multiple windows, and session sharing.
Screen is often used when a network connection to the terminal is unreliable, as a dropped network connection typically terminates all programs the user was running.
History [edit]
Screen was originally designed by Oliver Laumann and Carsten Bormann and published in 1987.[1]
Design criteria included faithful VT100 emulation[dubious ] (including ANSI X3.64 (ISO 6429) and ISO 2022) and reasonable performance for heavy daily use when character-based terminals were still common. Later, the at-the-time novel feature of disconnection/reattachment was added.
Ca. 1990 Oliver Laumann handed over maintenance of the code to Jürgen Weigert and Michael Schroeder at the University of Erlangen-Nuremberg, who later moved the project to the GNU Project and added features such as split-screen, cut-and-paste, and screen-sharing.[2]
