Exploring deep inside Mac OS X
A
s I mention in the first chapter of the book — at the beginning of our 
Snow Leopard odyssey — UNIX lurks deep beneath the shiny Aqua 
exterior of Mac OS X. UNIX is a tried-and-true operating system that’s been 
around for decades, since the days when mainframe computers were king. 
If you don’t believe that it’s a powerful (and popular) operating system, 
consider that over half of all Web servers on the Internet use some variety 
of UNIX as their operating system of choice.
Besides being battle-tested and having a long history, UNIX offers some 
fantastic features. Unlike the graphical world of Mac OS X, the keyboard 
plays an integral role while you’re using a UNIX-based operating system. 
Because UNIX is text-based, you’ll find that it’s evolved a large set of useful 
keyboard-driven commands that can perform powerful feats that a mouse 
user just can’t easily equal. This chapter examines the role of the keyboard 
in UNIX operating systems and describes how to execute standard file 
system commands. You also discover how to use Apple’s additional set of 
commands and install your own commands (and simple programs) from the 
Internet.
Why Use the Keyboard?
To begin benefiting from the UNIX underpinnings of Mac OS X, get used to 
doing things with the keyboard. Although mouse skills can be applied to 
UNIX, you’ll generally find performing UNIX functions faster and easier with 
the keyboard.
