I used to run Linux prior to buying my Mac mini (Late 2014) and I'm seeing a lot of similarities between Linux and macOS. Many years ago I dumped Microsoft Windows and installed Debian GNU/Linux. During my time with Linux I did a lot of distro-hopping and learned how to build my own computers from parts. I also became intimately familiar with Linux software and learned to write my own apps in python. I seem to be missing xclock, though. I'm finding that many of the command line apps I used on Linux are also there in macOS. Is macOS based on Linux? I was able to replicate the macOS desktop in many Linux distros using apps like Cairo Dock and menubar add-ons because I really liked the look of OS X Mountain Lion back in the day. Is the macOS desktop based on gnome 2.x or something similar? Maybe I'm just crazy but I'm seeing a lot of similarities.
