Screen is a great tool to separate your windows in a Linux environment. It enables you to switch between different screens effortlessly.

Basics

Start a new screen with the screen command. You will often use CTRL + A and then another key to do actions. For example, CTRL + A and ? will show you all commands.

To create a name to your Screen session, use the -S flag.

screen -S session_name

You can list all active screens with this command.
