Most Linux resources teach one of two things: basic commands, or advanced sysadmin work. The middle—where you learn to automate, manage users, configure storage, and secure a system—is where people get stuck.
I found a path that covers the full arc. It's on KandZ Tuts, and it's organized around four Linux Foundation certification tracks.
Here's what's inside.
01. LFCA — Linux Foundation Certified IT Associate
Foundational IT concepts, basic system use, command-line operations, and cloud environment principles.
This is the starting point. If you've never used a Linux terminal, the LFCA material gives you the mental model—how Linux organizes processes, files, permissions, and users—before you start automating anything.
02. Bash Scripting
Command-line execution, variable management, control flow structures, and core automation logic.
This sits between LFCA and LFCS deliberately. Bash is not an advanced topic—it's the glue between knowing commands and administering a system. If you can't script user creation, log rotation, or backup verification, you're doing manually what should be automated.
03. LFCS — Linux Foundation Certified Sysadmin
User account management, local storage and file system configuration, process controls, and baseline system security.
This is the day-to-day sysadmin layer. Users, storage, processes, and the security baseline that every production system needs.
04. LFCE — Linux Foundation Certified Engineer
Advanced network services, system firewalls, kernel tuning, and enterprise security hardening.
This is the layer that separates a sysadmin from an engineer. Network services, firewalls, kernel parameters, and hardening—the topics that show up in enterprise environments but rarely in tutorials.
Why the Certification Alignment Matters
You can learn Linux without following a certification track. Plenty of people do.
But certifications provide a defined scope. The Linux Foundation publishes competency domains for each exam. By structuring the curriculum around those domains, the path guarantees you're not missing entire categories of knowledge—storage, networking, security, process management—because you happened to never encounter them.
Even if you never sit for the exam, the certification outline is a useful checklist. This curriculum uses it as a map.
Who This Is For
- Beginners: Start at LFCA. Don't skip to Bash—the foundations matter.
- Developers who deploy: Start at LFCS. The Bash module is still worth reading for automation patterns.
- Sysadmins filling gaps: Jump to LFCE for network services, firewalls, and kernel tuning.
The Link
Free, no signup, four tracks.
If you've been meaning to learn Linux properly—not just enough to get by, but enough to administer and secure a system—this is the most structured free path I've found.
