Technical requirements

For this chapter, you will need a Linux system at hand where you can execute privileged commands, either using sudo or jumping straight to the root account (although we particularly recommend the first one). You’ll also need a Linux text editor of your choice that will produce pure text files. If you are going to edit on a Windows system, use a text editor that enables you to save Unix files. We recommend editing in the command line with one of your favorite command-line text editors: vim, emacs, joe, nano, or whatever suits you.
