It's been nearly 20 years since powershell came out.

It's 2026, you should not be using command prompt (or batch.) In powershell ls is a built in alias to get-childitem and has been for years, and in recent versions of windows you'd have to go out of your way to get a command prompt (you would have to open a powershell terminal and then run cmd.)

On one our linux machine filesystem became strange, probably because somebody mistyped `ls /bin` as `ln /bin`. I think docs say hardlinking folders is impossible or maybe /bin was a symlink.

Same! Closely followed by 'cat' lol. 'type' just doesn't register in my brain
