Mac OS X for Unix Geeks

@lt;DIV@gt;This book serves as a bridge for Unix developers and system administrators who've been lured to Mac OS X because of its Unix roots. When you first launch the Terminal application, you'll find yourself at home in a Unix shell, but like Apple's credo, Think Different, you'll soon find yourself doing things a little differently. Some of the standard Unix utilities you've grown accustomed to may not be there, /etc/passwd and /etc/group have been supplanted with something called Directory Services, and when it comes to developing applications, you'll find that things like library linking and compiling have a few new twists to them.@lt;/div@gt;
