This book is extremely readable. It gets a bit redundant in places, but I'm sure some of us need to be reminded of some key issues. About all that's missing is a list of good references on legal and accounting issues. This is the best book of its type I have seen. By the time you finish this book, you should be able to do pretty much everything you can do in any other OS at the command line level, and more besides.
Coverage is good.
Both the writing style and cartoons are entertaining. Yet Another Tools Book. Then as I skimmed it, I got excited. This looked like an excellent overview of tools for unix developers, beginning with the bundled tools, and going through the range of what's freely available over the net. It's a great idea.
