Question

WoW this is gonna sound dumb but...i am completely new to linux and i
was wondering if there was a website i could go to that has a list of
like basic commands and what you can do with them. Again i know this
sounds dumb but i have a computer and i cant do anything with it as of
yet because i cant get X up :( i think my distro cd's are bad...so i
wanna connect my box to the internet and download it from an ftp site
and build it myself. But i dont know how to do that yet :( so any help
would be great!
