Hi, I know a few books very cool:
Basic books: --> slackware book ( http://www.slackbook.org/html/book.html
--> redhat unleashed
--> red hat fedora for dummies
, all starting from zero.
Advanced books: --> linux bible 2008 Edition Boot Up to Ubuntu, Fedora, Knoppix, Debian, openSUSE and 11 other distributions
--> unix and linux system administration handbook
Advanced books is perfect to read after the basic books then this knowledge about linux become solid.
My website with examples of commands (I put a new command every day) starting from zero too.
