Review title: A great reference
Product review: I got this book as someone who had used UNIX before, but this was many years ago, and I had forgotten a lot. This book is great for picking up the functionalities of various UNIX tools - the explanations are clear and concise. It also works very well as a quick reference. The bulk of the book is devoted to bringing you up from a potentially zero-experience user to someone who can work with ease with editors, shells, and more. Simple examples are included throughout. The back of the book has a 250-page command reference section for quickly looking up how to use a particular command. You could read the whole book and progressively work with UNIX as a self-taught course, or just reference the sections you need.
