Why to use screen? #
Screen is a terminal multiplexer that allows you to run multiple terminal sessions in the background. With Screen, you can detach from a session, leaving processes running in the background, and later reattach to the session without losing any work. This is particularly useful for remote administration over SSH, where maintaining session continuity is crucial.
Key features:
- Screens can be named, making them easier to manage and close later.
- It allows running applications in the background without the need to set up a systemd service.
- Your session remains active even with an unstable network connection.
Important: Screens are not preserved after restarting a server, so they should not be used for permanent workloads.
