If you are a Unix geek, give Dr. su's quiz a try.
See if you can determine the meaning of each line of Unix commands below. As much as possible, these commands are valid to run on a typical Linux machine (though some of them would require setting up particular files or users).
I hope you enjoy solving Dr. su's quiz as much as I did composing it. Answers will follow in a later post.
