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 woke up this morning and linux came out of its sleepy thingy and then i noticed that the CPU was on 100% ALL the time. So i took a look in the processes list and gnome was at around 30-60% all the time and using around 200MB of my ram!! so was another program but can't remember what it was called and also control center was using around 10-20% CPU time, whilst using around 70MB. I couldn't understand this because it's as if they were working whilst I was asleep......on what? Also, i looked at the more info bit and it said that these prgrams were 'sleeping'....were they sleep processing or something b/c i thought they would just be cached and on 0% time? I did take a screenshot but it was tooo dog slow that I just rebooted.
Well there's a daemon(service) named 'cron' (or vcron or crond...) which executes tasks on a schedule(everyday or everymonth or at 6am of 24/12/03).
Well, 'slocate' is one of it's entries by default, and it executes 'updatedb' which updates your 'locate' database.
And this takes up alot of ressources(executing 'updatedb' I mean).
No, it isn't a backup because it doesn't contain the data of the files, it's a list(sort of) of the files(name with location, ex: /bin/bash), not the files themselves:
searching the list is faster than searching through the entire system.
