Changing the owner or group for a file

An interactive user might need to change the UID or GID for a file. To protect the data in a file from unauthorized users, the system controls who can change the file access:

To change the owner and, optionally, the group, the superuser can enter a chown command. The new owner can be identified with a user ID or a UID. The group, if specified, can be identified with a RACF® group name or a GID.
The CHOWN.UNRESTRICTED profile allows users to use the chown command to transfer ownership of their own files. SUPERUSER.FILESYS.CHOWN allows users to use chown to change ownership of any file.
To change the group owner to a specified GID, the superuser or the file owner can enter a chgrp command. The new group can be identified with a group ID.
