>From man cp:
--preserve[=ATTR_LIST]
preserve the specified attributes (default: mode,owner-
ship,timestamps), if possible additional attributes: links, all
--no-preserve=ATTR_LIST
don't preserve the specified attributes
Having set the ownership and permissions as above, as long as you
cp --no-preserve=ATTR_LIST
It should conform to the structure already established - I am no expert
and so I should test this 'theory' :)
