I have this book and I've been reading it off and on for a couple months now.
I think it's fair to mention as a caveat that this is not an introductory book for those who do not have previous experience as a Unix/Linux user. You're told how to use man, but beyond that there's no introduction to common shell commands; if you didn't already know how to cd and ls and such, this book won't teach you. You're told to edit various config files and such, but not how to use vi/emacs/et al to do so!
On the other hand, if you're already a luser and ready to step up to being a l33t and/or sysadmin, this book will definitely help. That was pretty much my situation, so I'm learning a lot from this tome. But if I hadn't already been familiar with finding my way around a Unix shell, I'd be totally lost.
