This chapter covers how to create and control basic shell scripts on a Linux system. Shell scripts are text files that contain a variety of commands that can be used to automate tasks and process information. Scripts have features of many programming languages, including variables, operators, conditionals, looping, and more. Because these features are related to the Bash shell, details are found in the bash man page.
