Try
www.tldp.org they have alot of stuff you can read. Also, if you bought a distro check out the user guide...and maybe the library....free books, and lots of em. I hear "Running Linux" by O'reily is pretty popular, once you get linux up and running try typing 'man <command>' where <command> might be (ls,mkdir,rmdir,less,cat,cp,mv,clear,date,cal...)
the list goes on and on...
I'm pretty new myself so that's all i can think of at the moment...had 10 hours of sleep in the last 2 days and probably won't get much tonight either...(this is more addictive than crack)
hope this helps a little
