Ok, but instead of looping I just once call grep on the current path. I would think it’s more efficient than looping, but I’m not sure …

I think our objective is very different, my function only intents to expand dots. The main challenge was to create it with one loop statement (I probably have to give that up), next was to only use builtins, external commands can be very resource demanding especially in a loop and adds unnecessary dependencies.
