Best way to learn Unix and Linux?

For my next job I already have lined up, I need to learn Unix and Linux commands and tricks. I just need some online sites with command listings, tricks, how the OS actually works, anything would help me start. I would like to learn how the OS works, then the commands. I have been in IT for a long time, but never with Unix mainframes and Linux OS's. If you know of the best couple of books to start, that would be great too.





Any help would be appreciated, and I always pick a best answer. Thanks.
