Hi everybody! (hi, doctor nick!)

I am taking a class on Linux+ (CompTIA certification) and my program's book is from 2001. I know that a lot is still relevent, but I know that Linux moves at the speed of... IEEE1394b, I dunno.

Anyhoo, what has changed since 2001 in the way of iptables, or traceroute, or userdel, or, well, anything in the way of common terminal commands?

I am not looking for a breakdown of individual options/switches available, but I would imagine a lot of progs have come and gone, as well as major/minor FS layouts, config locations, etc... Does anyone know of any off hand?

XOrg is obviously one...

Thnaks a lot for your responses.

well, linux is still based on the old UNIX from early seventies, so there isn't really any major changes. Weren't the 2.6 kernel after 2001, although that isn't much of an application. Things doesn't really evolve that much in the linux world. So its pretty amazing how it still manages to keep up with windows. But i guess somone would be able to point out one or two minor changes.
