I'm really eager to learn Linux system administration. I've tried looking for tutorials on YouTube but haven't found much that's helpful. There was one playlist I liked, but it didn't continue well. I've also studied networking and I'm currently learning Operating Systems and C programming. Is there anything else I should focus on or learn to become a good Linux sysadmin?

If you haven’t already, make sure to learn some bash scripting! It’s essential for Linux sysadmin work. You might find that you need some foundational bash skills to really excel in this area.
Since you already have some networking knowledge, I'd suggest diving deeper into the basics of protocols like TCP/UDP, DNS, DHCP, routing, SMTP, and the OSI model. Understanding these will really help you manage systems on any OS. That's a solid foundation for a sysadmin.
I have learnt networking basics. Now I want to focus on Linux sysadmin specifically.
Check out some great YouTube channels like Het_tanis, LearnlinuxTV, and the Red Hat playlists. Also, sites like Sadservers.com offer practical labs. There's even a Linux admin guide on GitHub that can be super helpful, along with a Linux hardening guide you might want to look into!
Thanks for these suggestions! I'll definitely check them out.
I haven't learned bash yet. Why would this not be the right sub for me?
