From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can you recommend websites, videos or challenges that help to learn Linux system administration? Something like the Linux Upskill Challenge or Bash challenges on hackerrank.com

Probably not exactly what you are looking for, but I'd recommend just starting to selfhost things. Have some old computer? Want to get a VPS?...

Something thats neat for selfhosting is pihole, if you feel up for it, go with docker as it makes things much easier in the long run.

Don't be too afraid to break your software. It will happen eventually. And always remember that stuff deleted with rm won't come back, thats what made me install a new OS on my VPS.

This! Selfhosting your own small apps is the best way to get practical, hands on experience with Linux administration.

It's also super fun and can be very helpful in some conditions.

On the other hand, the deeper you dive, the more at risk is your wallet, some day I will for sure have a server room somewhere.

Back in the day, we used to have "post2host" forums, where you could get VPS servers for free just by being active in the forum. That's where I cut my teeth on Linux!

Without that, 10 years ago, I would not have my career today. I am thankful.

That sounds awesome! For me personally, when we were still in highschool, I got a VPS on netcup with two friends together. That was about 2 years ago. We're phasing it out and all of us now have our own infrastructure.

Once it is no longer available, we plan to build a nextcloud federation.

The most important thing is to just start!
