Screen command

What is screen?

screen is a terminal multiplexer that allows you to manage several terminal sessions from a single window. This is particularly useful when you want to:

• Run commands that take a long time to execute.
• Disconnect and reconnect without interrupting your running processes.
• Collaborate by sharing a terminal session with others.

With screen, you can detach from a session, log out, and reconnect later without losing your running applications. It’s like having multiple monitors in one terminal!

• screen: Start a new session.
