The product page describes the features of this shirt as:
“A Linux cheat sheet printed upside-down, so you can glance down at it while hacking. Aimed at the non-guru, it’s mainly an overview of useful programs and in some cases handy arguments, and includes a guide to regular expressions.”
All I can say is if you have a cheat sheet with all the answers and you still don’t understand it, that means it’s time to lie, then change the subject… quickly.
