Summing Up
In this chapter, we have looked at a few of the many command line tools that operate on text. In the next chapter, we will look at several more. Admittedly, it may not seem imme- diately obvious how or why you might use some of these tools on a day-to-day basis, though we have tried to show some semi-practical examples of their use. We will find in later chapters that these tools form the basis of a tool set that is used to solve a host of practical problems. This will be particularly true when we get into shell scripting, where these tools will really show their worth.
