Question on chown in parallel (sh.itjust.works)

Hello I am seeking a simple solution to running a list of "chown -R" " commands in script.sh

It takes a long time to sequentially execute all of these chown commands recursively because the directories have so many files. I want to be able to tackle the root level directories in parallel to speed things up. I imagine there must be a simple way to do this while keeping the list of commands in a single file. xargs and some of the other things I saw online looked like bad fits or would be over engineering this problem.

Yeah since I learned on Windows servers for 20 years, I'm struggling on permissions and groups in Linux in general.

In Windows it's as easy as enabling 'children inherit parent' and then the users can go and create whatever and if they can write, they'll write it with inherited from the parent permissions. If you change a folder deeper, you can unlink inheritance from the parent and then it could also optionally be the new parent for all children permissions.

I tried a couple of times to do this in Linux and I've always struggled due to my own lack of knowledge and understanding. I feel reading it I keep coming to the wrong conclusion too perhaps based on my experience and bias in reading it.

Anyway I know it's not helpful but I feel the struggle.
