GNU Screen is one of the most useful utilities you can have at your disposal if you spend any time at all working at the command line. Screen allows you to manage multiple shell sessions from one terminal window or console, view multiple shell sessions at the same time, and even log into the same session from more than one location at a time.
The screen utility is a “window manager” that allows you to organize and work with multiple shell sessions in a very powerful way. Utilizing screen, you can manage shell sessions in all kinds of useful ways. This tutorial will show you how to display two or more sessions simultaneously in the same window, “detach” from a session and log in later, and even log into the same session from more than one system.
I would love to see OpenSuse (and Fedora) take up byobu, which makes GNU screen usable.
Byobu does make Screen easier to configure, but if you take the time it is fairly easy to set up Screen exactly as you like. I like Byobu, but there are some settings I would like to have a bit more control over.
