I've read several books on UNIX and the bash shell, and read the sections of several MacOSX books on UNIX. I started dabbling way way back, used Linux a bit on a rebuilt 486, installed some UNIX based stuff on pre-OS X Macs (there was Yellow Dog, and something else, whose name escapes me, I used on my 7100). Back then it was best to buy books. These days you can find anything you want to know along those lines on the internet. An excellent place to start:

Whenever I discover/see a useful command I add it to my "cheat sheet" along with an example and an explanation of it. I've organized my "cheat sheet" into categories that make sense to me, so that I can quickly find what I want.
A really handy helpful application for this sort of thing is Clix from Rixstep:

It has various lists of commands, categories and explanations. Truly great software, and it's free.
