🔹 Career Advantage

Linux skills are essential for roles in:

DevOps
Cloud engineering
Cybersecurity
System administration
SRE

🖥️ First Steps: The Linux Command Line

The command line interface (CLI) is the heart of Linux. If you master CLI basics, you unlock full control over the system.

Below are the essential commands every beginner should start with:
