I recently helped a friend with a dead Dell recover his files with the help of Knoppix, a Linux distro that boots right off a CD. I shared this success story with some friends of mine, one of whom wittily commented:

thank you linux… thank you for booting our dead windows computers so we can reinstall windows. You’re a really great… friend.

I know.. i know.. don’t feel sad.. we’ll always be friends.. I just.. don’t like you that way. Ya know?

Linux is the nerd who did your homework for you in high school while you were dating the quarterback.

So true…

ss64.com hosts this awesome reference to every single command line program and option available in MacOS X, Linux (Bash), Windows and (ugh) Oracle.

Wonderful reference and a great companion to Apple’s shell scripting primer.
