.. recommend a good Unix book or site that would teach a new person to the Operating System
A simple web search with key words "UNIX for beginners" showed me 657,000 results. But since you didn't define the word great
anywhere in your posts, there is no way we can help you out in terms of web sites.
However the following books are definitely worth reading:
1. The UNIX Programming Environment, by Brian W. Kernighan & Rob Pike
2. Design of the UNIX Operating System, by Maurice J. Bach
.. I am more looking for a solaris 10/unix guide ..
is the right place to read all the documentation related to Solaris 10.
