Not sure abt the answer but What made you think of this kind solution?
What is the reason don't you want single group ownership, You can add the user to whom you want to give access to this group.

Hi

Actually we have three groups with differnet users.

And we need to assign 3 groups as a owner of one single directory.

Also later we want to add more groupowner for this directory.

As Srikrishan stated, you want to use setacl. Here is a quick example:

setacl -m default:group:groupname:rw- some_dir

The above example will give a group rw access to a directory and the default keyword would give any files and folders created within the directory those default perms. One thing to note is that if you already have files under the folder that you are going to give the other groups access, you will need to change the perms on the files in the folder. Changing the perms with setacl does not propogate to the files and folders within the directory you made the permission changes to. In that case you can do something like this:

setacl -m group:groupname:rw- somefile

or

setacl -m group:groupname:rw- *

You could use the find command with -exec to make changes to all the files and folders underneath the directory.

Hope that helps.
