Hey, everyone, It seems like a number of switchers these days are Unix or Linux users, and I was wondering if anybody who's used (or uses) these OS'es could questions about Linux, Unix, and the Unix-ness of Mac OS X. Just to let you know where I'm coming from, I'm a former Windows (3.1/95/98/2k/NT/XP) user who was so sick of crashes, freezes, missing drivers, spyware, etc. that I started looking at Linux. Somehow, I ended up looking at Mac OS X, and was impressed enough to wait for a 15" Aluminum Powerbook. I love the UI, but I'm also curious about the Unix core and Unix/Linux in general. So, in no particular order: --I know Linux is based on Unix, but what differentiates the two? What can be done with one that can't be done with the other? (I'm sorry if this is a really idiotic question) --Are there any benefits in using a true Unix/Linux distro on PPC over using Jaguar (or Panther)? --Given the proprietary non-Unix layers on top of Darwin, is it really possible to do *everything* through the command line? --Are there any quirks in the tcsh Terminal in OS X that aren't in a regular Unix/Linux distro? I'm sure I'll think of more questions later, but I think I'll start here. Thanks in advance!
