Joe, have you found this site yet?

http://www.commandlinefu.com/commands/browse

A lot of good stuff there if you can figure out the context lol

The most recent cool trick (to me) that I started using was this:

cp file.txt{,.bak.`date +%Y%m%d.%H%M`}

For backing up a file before editing. Saves on specifying 2 files and 
includes a timestamp.
