I loaded windows 7 on a new hard disk and caddy to just get use to it because XP will soon not be supported. Windows 7 is really awful (I wont go into the details) but I need windows for the programmes that wont run in Linux. What I need now is a book for a Linux beginner of terminal commands or a way of building or understanding the system of commands. I run Ubuntu on an interrnal caddy. 12:05. I don't want to pay PC World prices for books. If I know what to look for I would try other sources.
