Default directory acls

Philippe Vervoort — Thu, 16 Feb 2006 11:09:33 GMT

I wonder if it's possible with default acls to arrange a situation that whatever group creates a file under a certain directory, the new file would have always the same group name.
The default directory acl then would look like this:
default:user::rwx
default:group:defaultgroupname:rw-
default:mask::rw-
default:other::rw-

Thanks for your input,
Philippe

Hi

In order to have the same ownership for every file under a directory do this:

chown -R user:group /dir

here specify the group you want to have the ownership on the dir and the files under it. (new and existing)

then do
chmod -R 755 /dir

Cheers

To do this:

"the new file would have always the same group name"

Enable the SGID bit on the directory:

chmod g+s /path/to/directory

Ivan,
Thanks, this is what I was looking for. I didn't know this trick !!

Vipulinux,
For your suggestion to work, it should have been chmod 2775 /dir , which is then essentially the same as Ivan's answer.
Thanks anyhow.

Philippe

chmod g+s
chmod 2775

is same. View the permission as,

ls -ld

see man chmod.
