command copies a single object or a group of objects.

It does not create an exact duplicate of files. You can copy a group of related objects by specifying a generic object name and the library in which the newly created objects are stored.

Note: The public and private authorities for the duplicate object will be the same as the original object. The owner of the duplicate object is either the user profile of the user who issues either the user profile of the user who issues the command or the group profile if the user the command or the group profile if the user profile of the user who issues the command is a profile of the user who issues the command is a member user profile that has specified that the member user profile that has specified that the group should be the owner. group should be the owner.
