Linux Command: screen

Terminal multiplexer for persistent sessions

Terminal — Process Management

Command

$ screen -S deploy

Output

Creates a new screen session named "deploy".

screen is a terminal multiplexer that creates persistent terminal sessions you can detach from and reattach to later. It allows running multiple shell sessions within a single terminal and keeps them alive after SSH disconnection. screen is essential for remote server work where SSH connections may drop. Unlike nohup, screen lets you reattach to running sessions and see their output. It supports multiple windows, split views, copy/paste between windows, and session sharing. screen has been the standard terminal multiplexer for decades. tmux is the more modern alternative with better defaults, but screen remains ubiquitous and available on virtually every Linux system.

Syntax

screen [OPTION]... [COMMAND]
