4:45AM Annalee Newitz | If you’re sick of opening a new terminal window for every application, GNU Screen is here to save the day. It’s a simple little program that comes pre-installed in Linux, BSD, and Mac OS X, and it allows you to page through multiple console applications from the same terminal window. Imagine reading your mail, editing text, and running a sorting application—all from the same terminal on your desktop! To get started, just type “screen” at the command line prompt. You’ll get a welcome screen, and then you’ll hit return. It looks like you’ve been taken back to the prompt, but now you’re in GNU Screen. Start an application, like a text editor. Then hit ctrl-a, followed by letter c. This creates a new window (you’ll see a new command prompt). Start your next application, then hit ctrl-a, followed by p. Now you’ve paged back to your previous window, with the text editor. Presto, two terminals in one! But wait, there’s more.
