Summary
In this chapter, we provided an introduction to regex, followed by more advanced topics, including metacharacters and capture groups. Finally, we learned how to apply these techniques to real-world applications of Bash scripting that you will find useful for pentesting.
Regex doesn’t have to be intimidating. With a basic understanding of characters, metacharacters, and flags, you’re well on your way to harnessing their power. Whether you’re editing text, analyzing data, or validating user input, regex can be an invaluable tool in your toolkit. Remember, like any skill, proficiency comes with practice. So, dive in, start experimenting, and soon they will become easy with a bit of practice.
In the next chapter, we’ll combine the regex concepts we learned in this chapter with common text parsing tools so that we can focus on common cybersecurity and pentesting tasks.
