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.

i am a newbiew linux user. i have got redhat linux setup at home. whenever linux boots it takes me immediately to the gui. now, i am unable to edit some files because the files show up as read only. i assume that if i have admin priviledge then i can edit the files. how do i get into admin mode in gui without reboot? and how do i edit the files?
Don't log in to a GUI as root. Log in as a normal user, open a terminal and use "su" (or "su - ") to become root. You'll be prompted for your root password. You will then be able to edit the files (edit: assuming of course they have write permissions for root).
As an alternative to Nylex' solution:
there are usually some terminals available under <ctrl><alt><F1..F6>. Login as root. Please note that those terminals don't have graphical capabilities, they are plain text terminals.
Some people use vi(m), others use emacs to edit files. Both are text based. There are other text-based editors that are probably easier to use for a newbie but they might have limitations for advanced editing. I don't have any experience with them as I use vi(m).
Maybe mc is the tool for you. Allows directory browsing and file editing in a possibly newbie friendly way.
Depending on what you have to modify, you might need to restart services before the changes take effect.
You can do the su(super user) from GUI itself. Launch either using mouse or ALT+F1. Go to System Settings(or similar option). And click on terminal. This will open a terminal in your GUI. Do su and provide the root password and enjoy editing and rootly powers !!!!
