Introduction

iii

prompt

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

will be 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 will need to type in the

text

command at the

boot:

prompt.

Additionally, we use several different strategies to draw your attention to certain pieces of information.

In order of how critical the information is to your system, these items will be 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.

Caution

Do not perform routine tasks as root — use a regular user account unless you need to use the root

account for system administration tasks.
