In this chapter, we got to know some of the basics of the bash shell. We covered man pages, a very important resource for everyone, from seasoned system administrators and kernel developers to newbie penetration testers and security engineers. We also use powerful and efficient ways to find certain files using very descriptive attributes and regular expressions. We covered another very important tool called grep, which allowed us to make effective use of regular expressions to find files based on their content and also pinpoint them in fine detail.

The next chapter will focus on customizing your bash terminal and enabling powerful features to make using your terminal a more information-rich and convenient experience.
