cp -a

cp -p

(preserve mode, ownership and timestamps)

Isn't this exactly what is not intended? – maxelost May 26 '11 at 16:03
@maxelost Only if the target file exists. There's two ways to interpret the question. Copy changes permissions to the user doing the copying, and that is likely not what is intented. – Daniel Beck May 26 '11 at 16:23

There is a better answer at ServerFault:

cp --no-preserve=all source target
