This is the eBook version of the printed book.

When Max OS X was introduced in 2001, it not only provided a visually attractive, intuitive interface that was easy for first-time users to learn and become productive on. It also provided a rock-solid Unix-based subsystem that opened up to power users, programmers and administrators new capabilities and a wealth of open-source technologies that could run on it. While most of the books published on Mac OS X in the years since 2001 have focused on using the graphical interface, only a handful of books have helped to understand how best to get the most productivity, power, and capabilities out of the operating system by tapping into command line and all the additional tools and techniques the BSD subsystem brought to the table. A few books have tried to teach Unix to Macophiles, and then others have tried to teach Mac to Unix geeks, but in the end no computer user really wants to have to "learn" an entire new system or language in order to be productive. What they want is a handy, portable quick cheat-sheet reference that provides them with the precise phrases they will need to use to achieve a desired effect or accomplish a desired goal.
