Overview of this book

Shell scripting is a quick method to prototype a complex application or a problem by automating tasks when working on Linux-based systems. Using both simple one-line commands and command sequences complex problems can be solved with ease, from text processing to backing up sysadmin tools. In this book, you’ll discover everything you need to know to master shell scripting and make informed choices about the elements you employ. Get to grips with the fundamentals of creating and running a script in normal mode, and in debug mode. Learn about various conditional statements' code snippets, and realize the power of repetition and loops in your shell script. Implement functions and edit files using the Stream Editor, script in Perl, program in Python – as well as complete coverage of other scripting languages to ensure you can choose the best tool for your project.

Feel proud that you have your "I can read" badge for shell scripting. We have developed our scripts to be interactive and prompting users for input during the script execution. These prompts can be used to simplify user operations on the command line. In this way, they do not need to remember the command line options or have passwords that end up stored in the command line history. When using passwords, we can silently store the value using the read -sp options.

In the next chapter, we will take our time to look at the conditional statements in bash.
