Shell Scripting: Expert Recipes for Linux, Bash, and More

What You Need to Use This Book

Chapter 2 addresses some of the options that are available for getting access to a shell environment of your own and getting it set up in a way that suits you. Experimenting on live systems is one option, but not a good one. Setting up a test account is better, and running a dedicated test machine, or a virtual machine, is even better. Virtualization software, such as VirtualBox or VMWare Player, is available at no cost and provides a risk-free way of testing even the most risky of root-owned scripts.
