Exploring Enterprise Linux🔗
Linux runs the infrastructure that matters — the servers, the pipelines, the containers, the cloud. This site takes you from first login to production confidence, at whatever level you need.
Where do you start?🔗
-
Day One
You write software and Linux is where it runs. You're not trying to become a sysadmin — you need to get connected, stay safe, and get back to building.
-
Essentials
You're a sysadmin, platform engineer, or SRE — or moving into one of those roles. You know IT. You need to know Linux specifically.
How It's Organized🔗
Four tracks past Day One, each with its own overview covering exactly what's inside.
-
The Linux commands and concepts every sysadmin and platform engineer must own — the command line, users & access, text & pipelines, system basics, and Bash scripting.
-
The kernel mechanisms underneath the commands — namespaces, cgroups, and capabilities (the primitives behind every container), plus swap and the OOM killer.
-
Mastery (coming soon)
Production-grade Linux for engineers who own infrastructure: storage and LVM, containers with Podman, system hardening, and performance tuning.
