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.

Haven't seen anyone mention https://overthewire.org/wargames/bandit/ yet. It's a Linux shell game where you need to solve problems using shell commands that only requires an ssh client on your machine: you ssh into the first server, solve a problem, and the solution points you to the next server. It starts easy (e.g. read out this file using
cat) but gets hard quickly. But you can always look up solutions when you're stuck. It gives a good idea what certain commands are used for and how they can be combined in powerful ways.This reminds me of a site called hackerslab back in the 2000s. I think you had to ssh in to some Korean server and try to get the password for the next level.
