In FreeBSD exist suiddir(http://www.freebsd.org/cgi/man.cgi?query=mount&sektion=8). You may mount partitions with suiddir option and add 4000 permissions.

In linux GFS2 support suiddir. Also you may use cron or inotify, to change file owner.

And what about dir not being a mountpoint? – drAlberT Oct 15 '10 at 10:08

bindbn's answer is correct but terse. There is no easy way to implement what you want on Linux - the setuid bit does not act like the setgid bit any of the standard filesystems. FreeBSD (and Linux using only the GFS2 filesystem) support a suiddir mount option that makes the setuid bit act like the setgid bit on directories. – akramer Feb 22 '11 at 03:21

You can have "all files belong to a group", by chmod g+s dir

If this doesn`t fit your needs, you have to deal with ACL and a default mask.

Hai Linux always associates a file or directory with a user and a group. For example, assume I have a file named webmaster.txt in my home directory. If I run the command ls -l webmaster.txt, I get the following result: -rw-rw-r- 1 root root 1024 Feb 21 15:10 example.txt

Here I think your directory is /root/test file is example.txt user is user1 & group is user1

If you want to change permission, gust follow the instruction

chown -R user1.user1 /root/test/

Best wishes

Although all the documentation seems to say otherwise, the sticky bit seems to do it to an extent.

e.g. to preserve the parent directory group.

chmod g+s [directory name]

Now any files or directories created within this directory inherit the parent group.

Not sure if this will be enough. Usually it's the owner/group of the current user or process that sets these.
