A quick side note

You should know about the "man" command. The man command allows you to look up any command. Even the "man" command itself. to use it simpley type in "man command here". See example below

$ man ls

this will give you a complet document on the ls command and all of it's switches/attributes. Switches/attributes are what I covered earlier see below

$ ls -al

"-al" are switches or attributes. I say or because some call them switches some call them attributes. I am sure there is one that is right but I just don't care.

I said you could even do this on the man command. see below

$ man man

It is that simple.
