What is the group ownership? An ownership group defines a subset of users and objects within the system. You can create ownership groups to further restrict access to specific resources that are defined in the ownership group. Only users with Security Administrator roles can configure and manage ownership groups.
What is file group owner? Initially, a file’s owner is identified by the user ID of the person who created the file. The owner of a file determines who may read, write (modify), or execute the file. Ownership can be changed with the chown command. Every user ID is assigned to a group with a unique group ID.
Can a directory have 2 owners? In the traditional Unix file permission system that’s not possible: a file has only a single owner. You could create a group containing just the two users that should have access and make that the owning group of the file (and give the desired permissions to that group).
