This book, as well as "The C Programming Language" by Kernighan and Ritchie are the bibles of Unix and C programming, in my opinion. These are from the command line days, but they are still timeless reading. Highly recommended. ( )

Still a great book even after all these years. Chapters 1-5 should be read by all UNIX and Linux users. The rest of the book is useful for UNIX developers.

Just don't expect it to explain how to use X/KDE/Gnome etc. ( )

This is one of the best technical books I've ever read. In a strange way it's still the best introduction to Linux, even though there are many outdated details. After all, _all_ technical are full of outdated details -- but it's the rare book indeed that can rise above implementation and express an entire philosophy of development concisely and readably.

Although an updated version would be even better, it's amazing how good of an introduction to UNIX this book remains more than twenty years after its publication. ( )
