Linux for Support and Operations
Learn Linux the practical way: commands, services, logs, permissions, and production-minded checks for support and engineering work.
This subject turns Linux from an intimidating black box into a structured environment you can inspect, reason about, and troubleshoot calmly.

Work through the topics in order to build command-line fluency, service and log awareness, permission reasoning, and performance-oriented troubleshooting habits.
