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'm relatively new to Linux, I bought Suse 9.0, and I am trying to learn as much as possible.
I would like to modify my PATH variable, i tried to write on the console PATH=$PATH:/:.
it was okay, but then I closed the console, then opened another one, and the PATH variable was still the old one. How can I change the default PATH variable?
There are several places that variables can be set. Globally (for all users) you could put the line
in the file /etc/profile or for each user you can put it in the file .bash_profile or .bashrc in the users home folder. The dot in front of the name makes the file a hidden file.
i went to this file you told, and I found the following commentary at the beginning:
# PLEASE DO NOT CHANGE /etc/profile. There are chances that your changes
# will be lost during system upgrades. Instead use /etc/profile.local for
# your local settings, favourite global aliases, VISUAL and EDITOR
# variables, etc ...
I then tried to look for /etc/profile.local, but that file doesn't exist. What must I do?
type, as root, "$EDITOR /etc/profile.local" (creating a new file), and add your commands.
Truthfully, though, this warning isn't a serious one. You can still edit the original files. They're just mentioning this because if you do any major upgrade your global files may be overwritten.
They say the same thing for other configuration files as well, but I think they assume most people are using their GUI tools and don't know how to edit a text file.
