I have a downloader service running, and I'd like it to set the setgid bit of every directory it creates. Its already doing so, but I suspect that's because at the moment, the parent directory also has setgid. What do I set the umask to?
I'm also wondering how umask, particularly in a systemd script, works for the "4th" digit. I understand that its inverted, so that umask = 002 is like chmod 775. But what about umask = 2002. Is that chmod 5775? or chmod 2775?
Thanks!

I believe the octal numbers for:
- sticky bit is
1, - setgid on directories:
2, and - setuid on files:
4.
So for the case your asking it would be: umask 2002 ==> 2775 for folders.
