What you need for this book

Any computer that has Linux OS installed on it will be sufficient for learning all the topics discussed in this book. I have personally tested all the commands and scripts in Ubuntu 12.10 distribution.

While learning, if you find that any utility has not installed alongside Ubuntu or any Debian-based distribution, then enter the following command to install this utility:

$ sudo apt-get update
$ sudo apt-get install package-name

The Internet should be available for the previous commands to run.

In Red Hat or any other rpm-based distribution, enter the following commands:

$ sudo yum update
$ sudo yum install package-name

If the Internet is connected, then using these commands, you can install any command or utility that is not already installed.
