While at university I did a lot of work on the SPARCs and this lead to Unix development as an early career for me. I moved into the windows world after that and I missed Unix so I picked up Linux around 98. I installed it on my work laptop of all things and made everything I needed work. Never looked back since although I run Windows VM for office and testing stuff.
I use powershell by default on windows and I prefer it for scripting any day of the week vs. shell scripts. It’s not the fastest but you can always plug in .net to your scripts to dramatically improve performance. Sure, I could write the script in rust or whatever to make it even faster, but that’s way more work than I need for the lifespan of the script.
