Bash does seem like a better fit for this kind of script since it is a lot more portable.
I.e.: It comes by default for many Linux distributions. For windows, a Git bash install will get you most utilities needed for large reliable scripts (grep, scp, find, sort, uniq, cat, tr, ls, etc.).
With that said, you should write it on whatever language you want, especially if it is for learning purposes, that’s where the fun comes from :)
Mint is pretty good, but I found the update center GUI app to always fail to update things like Firefox with some mirror error (regardless of whether you told it to use it or not). It happened for my old desktop (now my dad’s main computer), my LG laptop or used HP elitedesk G4. Using “sudo apt update” + “sudo apt upgrade” + Y (to confirm) on the command line was 10x easier and just worked. I do feel better/safe now that they use Linux for internet browsing instead of windows too.
