Using Screen for Session Management in your terminal

Screen is a session management utility for the unix/linux terminal. It serves multiple functions. Say you’re on a linux box and not running X Windows but you have the need to run multiple applications at once, without a window manager like we’re accustomed to in a GUI environment this can be troublesome, enter Screen. Screen allows you to run multiple instances of your terminal and switch back and forth between those instances with a stroke of the keyboard.

But Screen also serves another function. Have you ever been working remotely via an SSH session while in the middle of a running an app or working on a file and all of a sudden the connection simply drops? Again, Screen is here to save the day.
