To get the most out of this book

It is assumed that some readers may have limited or no knowledge about Linux operating systems. It is also assumed that some readers are Linux users but may need a bit of a refresher on interfacing with a Linux environment. 

The key to reinforcing each chapter to memory is by grabbing copies of various Linux distributions; namely CentOS, Fedora, and Ubuntu. Then install the various Operating Systems in a virtual environment such as VMware or VirtualBox. Next, follow along each chapters (the chapters are independent of each other so you can choose any given chapter to study/practice) by practicing inside the various Linux distributions in order to better grasp each chapter. After practicing the various chapters, you will become more productive within a Linux environment; this will empower you to be better equipped in mixed environments where there are both Windows and Linux Operating Systems.

You can follow the along the tutorials presented in Chapter 5, Installing a Linux Distribution of this book for getting started with installation.
