Screen

The screen command allows you to start a session on a remote computer and have it persist even if you log out. This is very useful if you’re running a long program so that you don’t have to stay logged in for that full duration.

To attach to an existing screen, do:

screen -r

This will return you to an existing session.

While you’re attached to a screen, all screen commands begin with:

Ctrl-a

To detach a session, type:

Ctrl-a d

To list the existing screens and whether you are attached to one, run:

screen -ls
