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.

Apologies if this has been asked before in the past - I've done a couple of searches and I haven't turned up much.
Q) I would like to know if anyone can point me towards any tools, scripts or code that would allow me to compare and report on the differences between 2 dumped lists of RPMs installed on to 2 different Red Hat Enterprise Linux installs ???
The dumped files have been created using a simple "rpm -qa >filename.txt"
The dumped lists of RPM files do not necessarily contain the same number of RPMs in each. Let's say the first is around 950 RPMs and the second is around 800.
>>> What I want is a summary list of RPMs that are installed on server #2 that are not on server #1 and vice versa. <<<
Up until now I have been copying the dump lists off the servers, putting them into a spreadsheet, sorting them and then going through doing a comparison manually - which takes around an hour. I'd prefer to be doing something else with my time, so I'm now looking for another solution.
Currently my thoughts are basically - I'm either going to have a quick hunt around the www for some form of reporting tool or script or I'll create my own script using either VBscript (please forgive the MS reference) or AWK.
