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.

Hi, Linux noob here... I have just installed RedHat 9 and during installation process downloaded and installed all suggested updates. I believe this is when kernel was updated from 2.4.20-8 to 2.4.20-19.9
But now during during startup in OS select menu, I get 3 choices: Dos, Linux 2.4.20-8 and Linux 2.4.20-19.9... It might be confusing to other users. How do I fix it so that only latest version shows up in the menu and delete old stuff so it doesn't take up space?
how do I view Linux logical drives? For example total space, free space, etc
[serge@localhost serge]$ rpm -e kernel-2.4.20-8
error: cannot get exclusive lock on /var/lib/rpm/Packages
error: cannot open Packages index using db3 - Operation not permitted (1)
error: cannot open Packages database in /var/lib/rpm
[serge@localhost serge]$ rpm -e kernel-source-2.4.20-8
error: package kernel-source-2.4.20-8 is not installed
does serge not have enough priviliges? I made the user part of adm group.
also where do I find grub.conf ? I tried searching for this file from root directory, but it says I need to run updatedb, which it seems I also don't have enough privileges
[serge@localhost serge]$ updatedb
fatal error: updatedb: You are not authorized to create a default slocate database!
aahh.. I feel like fish out of water, bear with me peeps.. also is there any good documentation on this stuff? like what the heck is rpm and etc?
this will prompt you for the root password. Input that and then do the above 2 commands that I gave you. in linux there are permissions to every file and directory..so you have to be root to do maintainence on your system (ex installing programs and removing them....etc etc.)
ok well you have to be root to install/uninstall rpm packages so "su -" to root and then uninstall it, also you have to be root to run updatedb....and the grub.conf file is in the /etc folder, oh and once again you have to be root to edit it
so before tackling any of these three things you want to do
and then the root password and then go about your business
