As rbatte1 posted, you have to design the "done" part into the way you transmit the file.

Without that, there is no elegant way to do it.

As said before, fuser is appropriate here.
Much better than comparing times with ls -l (which is less overhead than comparing the contents with cksum).
Code:
file=filename
while :
do
  pid=`fuser "$file" 2>/dev/null`
  [ -z "$pid" ] && break
  echo "$file is in use by process"
  ps -p "$pid"
  sleep 60
done
echo "$file is completed."
