Day 1: Introduction to Bash Scripting — What Is Bash & Why Use It?

Welcome to Day 1 of the Bash Scripting — Zero to Hero (Cybersecurity Edition) series! 🚀

In this lesson, we start from the very beginning and answer two simple but powerful questions:

👉 What is Bash?
👉 Why do professionals rely on it every day?

Bash isn’t just another terminal — it’s the tool that lets you control Linux, automate tasks, analyze logs, troubleshoot systems, and build real security workflows.

Today, you’ll learn the foundations in a simple, hands-on way — perfect for beginners.

🔥 What we cover in Day 1:

✔ What Bash actually is (and how it works)
✔ Difference between Terminal, Shell, and Bash
✔ Why Bash is essential for cybersecurity, DevOps, and Linux users
✔ Real examples of where Bash saves time
✔ What you’ll be able to build later in the series

You’ll walk away understanding why Bash matters — and feeling excited to start scripting.

💻 Who this is for:

• Beginners with zero coding experience
• Cybersecurity & ethical hacking learners
• Students curious about Linux automation
• Anyone tired of guessing terminal commands
