Coming Soon![[Category:SPO600]][https://www.gnu.org/software/screen/ GNU screen] is a utility which permits you to disconnect from a terminal session and reconnect from the same or a different location later. It also has a number of advanced features such as multiple sessions over a single connection and session sharing between multiple users. This tutorial covers the most basic and useful use-case. # Connect to a system, either by logging in locally or logging in remotely via [[SSH]].# Start screen: <code>screen -RaD</code>#* The <code>-RaD</code> options tell screen to start a session if none exists, or take over an existing session is one does exist, and to detach any existing remote connections to that session.# Perform whatever operations you desire.# Disconnect by pressing '''Ctrl-A''' then '''D'''.# You can now disconnect/close your local login or ssh connection.# To resume from the same or other location, issue the command from step 2. For additional details, see the manpage for screen. === Alternatives === An alternative to screen is [https://tmux.github.io/ tmux]. For a similar disconnect/reconnect capability for graphical applications, see VNC.
