GNU Screen and byobu

GNU Screen is a terminal multiplexer which allows you to run multiple console based applications within a single terminal. With screen there isn't a need to have multiple terminal windows open and if you're running in console mode you won't need to worry about running out of console.

Screen is extremely helpful when administering a remote machine allowing you to have multiple consoles through a single SSH tunnel. It also allows you to detach from a console and exit you SSH session and reattach to the console either locally or another SSH tunnel.
