screen (GNU Screen) is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Before using this tag, read the "Which site is more appropriate?" section of the tag wiki.
screen (GNU Screen) is used to create virtual terminals, which run by their own when not under direct user control. This is especially useful while working with a remote system, when a disconnect can occur at any moment. In this case, the screen session will continue to execute and you may reattach a running screen later.
Screen also allows you to execute multiple commands in a single terminal without losing control over them.
One additional trick is that a single virtual screen can be used by several users simultaneously, allowing them to guide and observe actions of each other.
