Bash Basics

To begin, create a new file with a .sh extension. We'll use shinobi.sh as our example.

You can create it instantly with touch:

touch shinobi.sh

Or, open it directly in your text editor:

nano shinobi.sh

For your script to execute, the very first line must specify the interpreter. This is called the Shebang. While #!/bin/bash instructs the operating system to use /bin/bash, its location can vary. For wider compatibility, use this:

#!/usr/bin/env bash

This tells the system to find bash within your PATH environment variable, ensuring your script runs consistently across different systems.
