Chapter 11. Shell Scripting

For the majority of this book, we've looked at the various elements that make up bash and how you can use them in writing shell scripts. If you've used other programming languages you will know that there is a difference between writing a piece of code that gets a job done and writing a piece of code that does the job but is also maintainable and conforms to what we could call "good practice."

This chapter will give a brief introduction to some aspects of good practice and writing maintainable shell scripts along with helpful tips and tricks that you can use to make writing scripts easier.
