Circle 1: Summoning Basics

Stop typing the same commands over and over. A Bash Script is a magical scroll where you write down a sequence of commands, and the machine executes them for you.

Tactical Intel: The Shebang (#!)

Every script needs a starting "Incantation" to tell the OS which language it's written in. For Bash, it is: #!/bin/bash

Directive: Scribe and Awaken

Scripts are just text files, but to make them "alive" (runnable), you must grant them Execute Permissions.

Tactical Objectives

1. Scribe the Scroll: Create a file named summon.sh.
   • Add #!/bin/bash on the first line.
   • Add echo "Rise, Automator!" on the second line.
2. Awaken the Code: Run chmod +x summon.sh to make it executable.
3. Perform the Summoning: Run ./summon.sh to see your code come to life.

Sorcerer's Insight

In the world of DevOps, we prefix local scripts with ./. This tells the shell to look for the file in the current directory rather than searching through the entire system.
