Introduction
Most servers, CI runners, and cloud VMs run Linux. Developers and QA SSH into boxes to check logs, configs, and deployments.
Why This Topic Matters
Fear of the terminal slows onboarding. Basic comfort separates “I only use GUI” from “I can unblock myself.”
Real-Life Example
Check if an API service is running on a staging server after a deploy — SSH in, list processes, tail logs.
Syntax Breakdown
Distros you may see: Ubuntu, Amazon Linux, RHEL. Shell: bash is default. Terminal vs GUI: same machine, text interface.
Step-by-Step Code Explanation
1. Open terminal on your laptop (WSL, macOS Terminal, or Linux desktop).
2. Run uname -a and whoami.
3. Note your home directory path.
Expected Output
You know why Linux matters and have a shell open.
