Understand what Linux is, master the file system, and learn how permissions protect your work. After this phase you can navigate any Linux system with confidence.
Parts 4 - 5: Command Line Power & Automation
Learn daily Bash workflows, then level up to writing scripts that automate real tasks — backups, health checks, and log analysis. This is where you start saving hours every week.
Parts 6 - 8: Processes, Networking & Packages
Manage running services with systemctl, troubleshoot networks with curl and dig, and keep your system up to date with package managers. After this phase you are job-ready.
