Hi all,

I want to configure a directory that way, that all new created files/directories in it belong to one specific group.

Background:
I need a common directory for a subset of my users. They all belong to a unique group (say xyz), what is NOT their primary group.
The common directory permits access only to members of that group xyz.
Now, I want to secure, that all files, the groupmembers will create, will automatically belong to group xyz.

I tried the gid bit, what worked for the directory content. But any subdirectories fall out of that rule.
And other ways - I don't know. Something with a cron job, that chowns all the time does not seem very productive...

Does anyone know, how to realize this?
Thanks in advance,
Clemens

Have you tried something like

$ mkdir xyz
$ chgrp xyz xyz
$ chmod g+rwsX xyz

Anything created in that directory should take on the group xyz including new directories. If however you copy other directories into this directory with something like "cp -p FILE..." then the copied file will keep its uid and gid.
