Chapter 1. What and Why of Scripting with Bash
Welcome to the what and why of bash scripting. My name is Andrew Mallett and I am a bash scripting junkie or perhaps more accurately: a scripting junkie. As an administrator, I fail to see the need to do repetitive tasks manually. We get time for more interesting things when we choose scripts to carry out the laborious tasks that we don't like. In this chapter, we will introduce you to the what and why of bash scripting. If you are new, it will help you become familiar with scripts and also provide some great insights for those with more experience and who want to improve their skills. As we make our way through the chapter, each element is designed to be added to your knowledge to help you achieve your goals. While doing so, we will be covering the following topics:
- Bash vulnerabilities
- The bash command hierarchy
- Preparing text editors for scripting
- Creating and executing scripts
- Debugging your scripts
