In this chapter, we dived in to some more advanced concepts relating to shell commands, such as redirection, Bash history, command aliases, some command-line tricks, and more. Working with the shell is definitely something you'll continue to improve upon, so don't be worried if you have any trouble committing all of this knowledge to memory. After over 16 years working with Linux, I'm still learning new things myself. The main takeaway in this chapter is to serve as a starting point to broaden your command-line techniques, and also serve as the basis for future exploration into the subject.
In the next chapter, we'll take a look at virtualization, which is one of my favorite subjects. We'll set up our very own virtualization server, which will be a lot of fun. See you there!
