Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

im busy reading a book on RHEL and are using centos to follow along and hopefully learn about Red hat.
anyway...the book started on about printers and i was trying to follow and saw that there were things missing in my OS like
system - administration - printers was not in my menu...after googling i found that you need to run a yum command (is this to actually install this functionality?) so i opened a terminal and tried to run
yum install system-config-printer then it moaned at me about root access...so i googled that and went from a terminal
then entered the password and ran the yum command again.
it then loaded plug ins and mirror speeds (what ever they are)
then came up with an error No package system.config.printers available. followed by
nothing to do (if only that was true)
and then back to the command line...what am i missing? do i have to install a package of some sort...looked in install software but couldnt see anything relevant.
and while i have you...what is the difference with running a terminal from within the gui...and going into the shell (black screen with white writing) is there a difference regarding functionality...or is the command line from a proper shell faster as it doenst have gui in memory etc? just curious...
the book is the study guide for red hat enterprise linux exams.
i did see su in the text...but it didnt actually explain how you would use it ie...i did see what it did...but had to work out how to apply it.
i copied the text yum install system.config.printers from a web site...and im still having the same error
the one with the - - - i also copied but i have tried both
thanks for your help..also did you see my question about the terminal?
i will definitly look at getting the book you suggested,,,

Re Terminal; main difference is that you can start a GUI prog from a terminal-in-GUI, but I don't think you can do that from the standalone/console type terminal eg ctrl-alt-f1 etc (basically that would not be running the X-win code required).
As for your probs with yum etc, please post EXACTLY what you did and the EXACT results; even a single typo can cause major issues.
Also, to get the full root env, use
Note the '-' aka hyphen; without that you get logged in as root BUT you retain your original non-root environment.
The package is called system-config-printer not system.config.printers. You need to type it exactly correctly. In this case the typo was harmless, but in the future when you are executing powerful commands such as rm as the superuser, a single error in spelling/punctuation/syntax can break your system. When in doubt use the Copy and Paste features and only use commands from reputable sources that you trust.
