ii
Updated Users and Groups Chapter
The Users and Groups chapter has been updated.
Before reading this guide, you should be familiar with the contents of the Red Hat Enterprise Linux
Installation Guide concerning installation issues, the Red Hat Enterprise Linux Introduction to System
Administration for basic administration concepts, the Red Hat Enterprise Linux System Administration
Guide for general customization instructions, and the Red Hat Enterprise Linux Security Guide for
security related instructions. The Red Hat Enterprise Linux Reference Guide contains information
about topics for advanced users.
HTML, PDF, and RPM versions of the manuals are available on the Red Hat Enterprise Linux Docu-
mentation CD and online at http://www.redhat.com/docs/.
Note
Although this manual reflects the most current information possible, read the Red Hat Enterprise
Linux Release Notes for information that may not have been available prior to our documenta-
tion being finalized. They can be found on the Red Hat Enterprise Linux CD #1 and online at
http://www.redhat.com/docs/.

2. Finding Appropriate Documentation

You need documentation that is appropriate to your level of Linux expertise. Otherwise, you might
feel overwhelmed or may not find the necessary information to answer any questions. The Red Hat
Enterprise Linux Reference Guide deals with the more technical aspects and options of a Red Hat
Enterprise Linux system. This section helps you decide whether to look in this manual for the infor-
mation you need or consider other Red Hat Enterprise Linux manuals, including online sources, in
your search.
Three different categories of people use Red Hat Enterprise Linux, and each of these categories require
different sets of documentation and informative sources. To help you figure out where you should start,
determine your own experience level:
New to Linux
This type of user has never used any Linux (or Linux-like) operating system before or has had
only limited exposure to Linux. They may or may not have experience using other operating
systems (such as Windows). Is this you? If so, skip ahead to Section 2.1 Documentation For
First-Time Linux Users.
Some Linux Experience
This type of user has installed and successfully used Linux (but not Red Hat Enterprise Linux)
before or may have equivalent experience with other Linux-like operating systems. Does this
describe you? If so, turn to Section 2.2 For the More Experienced.
Experienced User
This type of user has installed and successfully used Red Hat Enterprise Linux before. If this
describes you, turn to Section 2.3 Documentation for Linux Gurus.
