"Screen"
I've tried hard to get into Screen. The ability to detach sessions from one terminal and hop back in from another terminal would have come in handy many times in the past.
Basic usage is pretty simple and the man pages are done very well but what I need right now is a "How to start using screen in 5 minutes" type of deal. It is usually hard not to find a ton of information about these treasures due to the amount of console fanatics out there that tend to document every aspect of their configurations. Unfortunately, searching for "screen" is like searching for "computer". I wonder if this has deterred others from picking it up in the past?
I found a solution after toying with different searches for awhile—both "GNU/Screen" and "/usr/bin/screen" return decent results. Here's a good introductory article. The Screen FAQ is hardcore but I was able pull a few good tips anyway. And last but not least I found my fanatic: Making the Anti-Switch - an excellent get up and running quick guide with a sample ~/.screenrc file.
