!!!''screen'' Terminal Multiplexer (ähnlich [tmux|pagename])

{{screen}} ermöglicht es, eine Terminal-Sitzung über {{ssh}} sehr flexibel zu nutzen.

"Screen" bietet sich für drei Szenarien an:

    * mehrere Nutzer.innen können eine Sitzung teilen
    * das Sitzungsterminal kann in mehrere Fensterbereiche ("panes") geteilt werden
    * im Sitzungsterminal können mehrere Sitzungen offengehalten werden ("buffer")
    
Es gelten ähnliche Erläuterungen wie für [tmux|pagename].


Beispiel für eine Konfigurationsdatei "~/.screenrc":

%%prettify 
{{{
#
# This is an example for the global screenrc file.
# You may want to install this file as /usr/local/etc/screenrc.
# Check config.h for the exact location.
