Review title: Excellent intro and reference.
Product review: This is a solid introduction and reference book for folks who are GUI-literate but not UNIX folks. (I learned UNIX back around 1982 and have desperately tried to ignore it since.) Much more useful than a general UNIX or Linux book, because it includes the specific aspects of OS X that you need to know about: where things are put, what special utilities are available, how the file system is laid out, OS X system management, etc.The only significant complaint I have is that the book devotes a LOT of space to vim, emacs, and other pure-text editors. The terminal is fine when you need it, but why would you edit text in a non-GUI environment? If you are a serious programmer, you'll want to work in an IDE (integrated development environment) with syntax coloring, hints, debug, etc. These chapters seem like a waste of time.
