After the interesting little aside in one of the other threads, I figured it'd be better to discuss somewhere in a more appropriate thread than hijacking another So I picked up Unix for Dummies and decided to take the plunge into the world of Unix so I can become terminal savy. Right now I am purely a newbie, so all I know are the basic "uptime" and "who am i" commands for now. I know, it's pretty basic, but at least I am taking the first step. I've found that reading all this info about Unix can be quite overwhelming, but I just can't help but want to know all I can. I figured it'd be good to know how to use the terminal to get the most out of OS X when I upgrade with a new PowerBook soon, and incase I run across a need to use Unix in the future. So who else out there is learning/a die hard Unix fan/a poweruser/or just plain enjoy using the terminal? What kinds of commands have you found invalible for the OS X user? What kind of experiences, pluses with using Unix, etc have you come up with? If you have an opinion on Unix, then by all means, post!
