mymove() {
local origin=$1
local target=$2
while read path; do
# do the work for each file here
done
}
find $origin | mymove $origin $target
You can use compute the relative path names by stripping $origin from the
stard and you can do whatever checks you want with "test".

I would not override but it's interesting to compare the files
yes. That way we can avoid complaining about a conflict when in fact
both files are identical. And we can silently drop our copy.
