Introduction

iii

prompt

A prompt, which is a computer’s way of signifying that it is ready for you to input something, is

shown in this style. Examples:

[stephen@maturin stephen]$

leopard login:

user input

Text that the user has to type, either on the command line, or into a text box on a GUI screen, is

displayed in this style. In the following example,

text

is displayed in this style:

To boot your system into the text based installation program, you must type in the

text

com-

mand at the

boot:

prompt.

replaceable

Text used for examples which is meant to be replaced with data provided by the user is displayed

in this style. In the following example,

version-number

is displayed in this style:

The directory for the kernel source is

/usr/src/

version-number

, where

version-number

is the version of the kernel installed on this system.

Additionally, we use several different strategies to draw your attention to certain pieces of informa-

tion. In order of how critical the information is to your system, these items are marked as note, tip,

important, caution, or a warning. For example:

Note

Remember that Linux is case sensitive. In other words, a rose is not a ROSE is not a rOsE.

Tip

The directory

/usr/share/doc/

contains additional documentation for packages installed on your

system.

Important

If you modify the DHCP configuration file, the changes will not take effect until you restart the DHCP

daemon.
