Mac OS X has the ability to run the 18,000 existing Mac programs and an unlimited supply of Unix and Open Source software. This text offers all audiences - both long time Mac users and converts - a complete guide to operating system from its BSD Unix foundation to Aqua, the new user interface. The book's "Unix Command Reference" is a complete and thorough coverage of Mac OS X Unix commands. Each command and option in this section has been painstakingly tested and checked against Jaguar - even the manpages that ship with the system can't compete in accuracy. The reference incorporates the new command-line tools that come with Apple's Developer tools. It familiarizes readers with the Finder and the Dock, file management, system configuration, network administration issues, and more. Later chapters include bonus material for the Unix user, including advanced use of the Terminal and how to configure a DAMP (Darwin, Apache, MySQL, Perl/PHP) Web publishing system. Other topics covered in the book include: filesystem overview; running Java applications; system and Network Administration; directory services and netinfo; scripting on Mac OS X; using CVS; Unix Command Reference; and installing and running X Windows and BSD Unix applications. The book follows the common-sense O'Reilly approach, aiming to cut through the hype and give readers practical details they can use every day. Serious users who want more from their system should find everything they need to know systematically documented in the book.
