Howdy, welcome to lesson 7.
This lesson is all about managing text files.
I'll first tell you about some of the common text tools.
Then it's time to talk about GREP, one of the most important tools that you will work
with on Linux.
Next, you'll learn how to make GREP and other tools even more powerful, by using irregular
expressions.
After that, we'll have a look at the org and set utilities.
This lesson ends with the lab, and I'll also show you the lab solution.
