A sample copy of this book arrived in my mailbox at the university (UofM-Dearborn) where I teach. I began reading it to brush up and enhance my understanding of Unix- and Linux- based systems.

I receive several "sample books" every year, and sometimes I give them a once over and shelve them until they may (or may not) be needed in the future. THIS book was an exception. It was written in a very professional, but often humorous fashion.

I have read a lot on Unix, and some on Linux, and I must say that without a doubt, this is the BEST book I've ever read on the subject(s), period. It has a lot of footnote "Computer Nerd" humor.

So whether you're well-versed in computer science and/or related topics, or you are new to the field(s), this book is a must-have. I strongly recommend it.
