Persistent Terminal Sessions

Have you ever had a remote terminal session running, only to have your connection drop out half way through a large task? Then, you reconnect, not knowing anything about its progress (if any) and current status.
Screen is the solution to this problem. Screen allows you to start terminal sessions that you can disconnect from and resume at any time.
I personally use screen a lot with Node.js web servers, so I can kick off the process, and resume my terminal session to check logs or errors, or restart the process if it died.
This article is an introduction to Screen for the average developer, including a few tips and tricks.

Installing

Screen is a Unix tool, so with Ubuntu, you can use apt-get to install it:

sudo apt-get install screen
