Linux Administration Learning Path
Four steps from your first terminal session to confidently managing production Linux servers. This path emphasizes hands-on skills—every concept links to resources with practical examples and real-world context.
Estimated time: 6–8 weeks at 5–10 hours per week
Command-Line Fundamentals
Navigate the filesystem, manage files, understand permissions, and work with pipes and redirects. The shell is your primary interface—master it early.
Shell Scripting
Automate repetitive tasks with bash scripts. Learn variables, loops, conditionals, and functions. Write scripts that are portable, readable, and maintainable.
Service and Process Management
Understand systemd, cron, log management, and process lifecycle. Learn to monitor, start, stop, and troubleshoot services on production systems.
Security and Hardening
Firewall configuration, SSH hardening, user management, and security auditing. Every Linux administrator needs to think about defense from day one.
