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.

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 fan-
tastic features. Unlike the graphical world of Mac OS X, the keyboard plays
an integral role in 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 operat-
ing 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.
