5 {{{screen}}} is a handy tool. It lets you get more out of a terminal session, whether in a window, via ssh, or by some more esoteric means.
6 It's original reason for existence was allowing you to switch between subsessions on a [http://en.wikipedia.org/wiki/Video_terminal video-display terminal],
7 but grew to allow sessions that could be detached and reattached (if you went home for the day, or say you were connecting via a glitchy network) and eventually
8 to allow the same session to be simultaneously accessed from multiple places.
12 1. Pick a machine to run your screen session on. If you don't know of any options, linux.mit.edu (Linerva) is a good choice.
13 2. ssh to that machine.
17 To detach, type "C-a d". To reattach, type {{{screen -dr}}}
19 If you close your ssh connection without detaching, or lose your network connection.
21 1. run {{{screen -dr}}}
24 Once you're comfortable with this, hit "C-a C-c". This creates what screen calls a new "window"; it should give you a new shell prompt,
25 and you can do stuff at it. If you want to switch back to the old "window", hit "C-a C-a". You can create as many "windows" as you want; you can
26 switch to the first 10 of them with "C-a 0" through "C-a 9" and see a list of what's open with "C-a w".
