Hi,
A file or a directory can be owned by only one user and one group, correct me if I am wrong. And what I would like to do is add more than one user and a group to it. Let's say there is a directory called "mydir" which belongs to the user and group jack:group_jill. Now, I would like to add (not chown) the user "john" and group "acme" to this directory "mydir". How can I do this?
Can a file have more than one owner and a group?
Thanks!
