Hello I am seeking a simple solution to running a list of “chown -R” <mydir>" 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.

    I don’t really understand your use case.

    It sounds like you have multiple users creating files in a directory, and some users are creating them with more-restrictive permissions than you want – like, you want to force them to make their stuff accessible by everyone else – and you’re trying to avoid that by regularly modifying all the permissions?

    If you set the sgid bit on the parent directory, then by default, things created in that directory will inherit the group of the parent directory.

    But a user can still change permissions so that that isn’t the case.

    It’s possible that you could use ACLs or something like that to address your problem, but I don’t know what it is that you’re trying to achieve.

      What you proposed with sgid sounds like it might be what i need. All of the users are controlled my me, it’s just when they connect to the smb share of the main system from other devices, i figured it was good security to use an account that is separate from my main account on the system, so they can’t access the entire system or execute sudo commands
