I have a constantly running server that would be a perfect on which to run torrent downloads. The only catch is that the server is headless -- it has no monitor or keyboard. To overcome this obstacle, I use rTorrent as my torrent client, and GNU Screen so that I can disconnect my terminal session and leave rTorrent running.

In this article I will describe a very useful program: GNU Screen. Usually this program is used by people who have a shell account on a Unix server. But it can be also helpful to people who haven’t yet started to use a terminal or even Linux/Unix at all. Screen — simply — is a program which enables users to create more system shells without the need of logging in multiple times.
