Automating Package Removal in Debian

This is a quick way to remove packages matching a grep pattern. Use with caution!

This removes all the gimp packages:

apt-get remove --purge `dpkg -l | grep gimp | cut -d ' ' -f 3`


CVS Demystified

CVS stands for Concurrent Versioning System, it is most useful when there is a team of developers working on the project. cvs keeps track of all changes to the source tree and logs each operation, so at any point you can revert to an earlier version. It is also a useful backup tool if it is being used on a project that involves only one developer.

Introduction

This document will provide some of the basic commands of Unix. I
suggest you print this if you are a first time Unix user, or are about
to install Unix for the first time. It is always good to have a
reference, so that when you see your first prompt, you have an idea of
how to move around.
