Question

Setting default group ownership on new files in Linux

Asked by: jessc7

How do I force a group ownership assignment when a new file is created in a certain directory on a Linux server?

When a new file or directory is created today, the default ownership is "users". I want it to default to a different, custom group.

Hi,

you can have new files inherit the group ownership of their parent directory by setting the appropriate "s" flag for that directory -

chmod g+s /path/to/directory

wmp

Another way is to use ACL's
http://www.suse.de/~agruen/acl/linux-acls/online/

This is Suse's page, other distros support it too as it is part of the kernel for at least
ext*, xfs & reiserfs filesystems.

How do I apply this to sub-directories, so it cascades down? Once I get past the root directory and create a file, I lose the settings apparently.

I don't quite get the ACL stuff yet - and seems like it may be overkill for assigning the default group assignment? Not sure.
