Basic Linux System Administration (LINSYS-1)

Ready to get into DevOps/SRE? Start with Linux.

Every cloud server, every DevOps pipeline, every modern internet infrastructure runs on Linux. Yet most beginners struggle to learn it effectively. They get lost in complex documentation, overwhelmed by command-line interfaces, or stuck with outdated tutorials that don’t reflect real-world practices.

What if you could learn Linux from someone who’s been doing it for 30+ years?

I started using Linux in 1993. And since 2001, I’ve been teaching what I know about system administration. In this course, I’ll make sure that you have a great start into Linux system administration yourself.
