You are probably suffering from an alias installed by your distro (this
behavior sounds like what would happen if you do alias cp='cp -i').  This
surprising behavior is why I personally recommend setting alias names to
something different than the POSIX tool name.  Try '\cp -f' to see if the
behavior matches your expectations.

At any rate, POSIX specifies that cp -f does not override -i - we are
still required to ask for a prompt, even though you added -f:
