One of the things that makes the shell an invaluable tool is the amount of available text processing commands, and the ability to easily pipe them into each other to build complex text processing workflows. These commands can make it trivial to perform text and data analysis, convert data between different formats, filter lines, etc. This chapter will go over some of the most common and useful text processing commands the shell has to offer, and will demonstrate real-life workflows piping them together.
This chapter will help you take your first steps in the terminal, this almost mythical (The Matrix, anyone?) application we oftentimes imagine hackers type in really fast. We will see how it works and how it can empower you, increase your productivity and give you insights about how your computer works.
