In this chapter, we've seen how to quickly verify the syntax of a knife subcommand or to review at length the full wealth of the help system contents. We have looked at some of the most often used knife subcommands as well as a few that may be generally overlooked. We also took a deep dive into the knife search subcommand. Then, we shifted gears to explore some existing community knife plugins—one for Windows and and one for EC2. Finally, we cut our way through the exciting topic of creating our own knife plugins. Now, with our newly sharpened knife skills, let's begin to explore the management of your infrastructure code with the use of roles, environments, and the new and exciting feature that is policies, in the next chapter.
