Hello World Bash

Let's build your first script. Create shinobi.sh and add the essential shebang, followed by your Hello World message:

touch shinobi.sh

Now, open shinobi.sh and add this content:

#!/usr/bin/env bash

echo "Hello World!"

Save and close the file.

Next, make your script executable:

chmod +x shinobi.sh

Execute your script directly:

./shinobi.sh

You'll see "Hello World!" printed.

Alternatively, you can run the script by explicitly calling the bash interpreter:

bash shinobi.sh

For quick tests, echo works directly in your terminal:

echo "Hello Shinobi!"

Scripts become powerful when combining multiple commands for automated tasks. This is your first step.
