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.

How do I become an admin, so I can edit all of the files. For example when I try to access the root file, it says "You do not have the permission necessary to view the contents of 'root'". Also I want to edit the rc.local file(/etc/rc.d), but it won't let me...why?
It's also good practice to get in the habit of typing a dash after su, as in:
Which makes it execute root's startup script (in a new shell) when you become root. This will set you up so that you have root's path, which is probably different from most user's paths. This solves some problems of people not having common commands (like ifconfig) in their path, even after they've become root - they didn't adopt root's settings.
This goes for su'ing to anything. From root, you can su to anyone's user account, and you'd still want to "su - username". You can, of course, su to anyone from anyone (on non-wheel systems), but if you're root, it doesn't ask for passwords - Yet another affirmation of what people above this post have said: beware if you're root, you *can* very easily screw something up.
okay...i logged in as root. I want to edit the rc.local file (/etc/rc.d). I was told that in this file you can add lines that will run during startup. I want to do this because eveytime I log in, my internet wont work, so I have to go to the terminal every time and type:
I have to do this for my drivers for my linksys wmp11 card. So by putting these files in the rc.local file, they will simply just run on startup....right?? But the thing is, I cant edit the file (or i'm just stupid, and not doing something right). Can someone please tell me how to edit this file. Thanks!
