Hi, I have changed directory ownership permissions recursively such that it is owned by username:groupname , where groupname is not the default group, i.e., username. However, when a user creates a new file the default permissions are again username:username. How can I give ownership permissions on a particular directory so that any files created in that directory will always have specifc username:groupname permissions? Also is there any option that would allow only owner to delete files, even though group has rwx permissions? Thanks, CS.
