In this tutorial we’ll be writing our first bash script for Raspberry Pi. We’ll create a directory to keep this and future scripts, write the actual script, and set it up as something that can be executed from the shell.

Scripts are an incredibly powerful tool to have in your toolbox. In essence, a script is just a sequence of commands that you could otherwise have entered into the shell. The power of scripts is that they can be used to make decisions, and execute certain commands based off that decision. Scripts can be scheduled to run at certain times, and can execute trigger other scripts.

In this tutorial we’re assuming you’re familiar with how to use the terminal to navigate the file system and create files and directories.
