In May 2015, on openSUSE Conference, Jürgen Weigert invited Alexander Naumov to help to develop and maintain GNU screen. Because there were some unofficial "Screen 4.1" releases floating around the Internet, he called this new release "Screen 4.2.0". ![]() Sławiński proceeded to put out the first new Screen release in half a decade. In response, Laumann granted him maintainership. Wanting to change this, Amadeusz Sławiński volunteered to help. īy 2014, development had slowed to a crawl. ![]() Later, the at-the-time novel feature of disconnection/reattachment was added.Īround 1990, 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 scrollback, split-screen, copy-and-paste, and screen sharing. ĭesign criteria included VT100 emulation (including ANSI X3.64 (ISO 6429) and ISO 2022) and reasonable performance for heavy daily use when character-based terminals were still common. Screen was originally designed by Oliver Laumann and Carsten Bormann at the Technical University of Berlin and published in 1987. Running the applications under screen means that the session does not terminate – only the now-defunct terminal gets detached – so applications don't even know the terminal has detached, and allows the user to reattach the session later and continue working from where they left off.Įxample of working with the GNU Screen History 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 (child processes of the login session), due to the session ending and sending a "hangup" signal ( SIGHUP) to all the child processes. This enables the following features: persistence, multiple windows, and session sharing. 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. 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. Further information: Terminal multiplexer ![]()
