Your problem might be caused by an alias for cp command created in your system by default (you can see al your aliases by typing "alias"). For example, my system has the following alis by default: alias cp='cp -i', where -i overrides -f option, i.e. cp will always prompt for overwriting confirmation.

What you need in such case (that'll actually work even if you don't have an alias) is to feed "yes" to that confirmation. To do that simply modify your cp command to look like this:

yes | cp /source/file /destination
