Yeah, I find that - even though it is a little old - it is invaluable for newbs. Just goes to show, looking at the LDP can help lots.
Just as a side note: When you get used to Linux commands, you'll find it a pain using DOS commands again. You can get around this by installing Cygwin in Windows and adding it to your path. You can use (all/some) bash commands (like ls) under Dos that way.
