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 have installed Linux redhat enteprise WS 4.0 on a partition of a pc equipped with a dual-core cpu. Unfortunately, when I go to System Monitor I see only 1 cpu (CPU1). How can I tell to the OS that there are two processors?
The same happens when I install the same version of linux (unfortunately I cannot change kind of linux since I must use a programm running only on that version) as virtual machine on an iMac again possesing an intel dual-core....
There is a good chance that the OS already knows there are two cores but the System Monitor isn't showing both of them.One way to check this would be to open a terminal and type "top" without the quotes.Look for the part where top shows Cpu(s).Press 1 on your keyboard.You should now see the second core.The application htop will show both cores by default if you like that better.If there are not two cores or cpus showing you may not have a smp kernel installed by I'm thinking that the installer will have detected your hardware and installed the proper one.Another thing to try is entering "uname -a" into a terminal,the result of this will show if there is a smp kernel installed.Cheers.
