Code:
find . -type f -name "some*.fil" -exec cp -iv {} /destination/folder \;
# or less likely...
find . -type f -name "some*.fil" -print0 | xargs -J % cp -iv /destination %
The second might fail if cp does not handle the incoming data with the addtion of a parameter, in other words it might be missing an item in the line to not fail.
