Summary

In this chapter, we covered the breadth of bash's control structures and dived into input/output redirection. These features can be leveraged to enhance your command-line functions and enable small scripts that process data in loops without having to resort to a full-fledged programming language for some simple data processing.

We also looked at a lot of ways to slice and dice characters and strings. While many use cases may be covered using string manipulation alone, often we'll want to delve a little deeper into the data represented by these streams to extract useful information.

In the next chapter, we'll look at doing this by using the command line and data streams as a database.
