Seems like deja vu. Compare the file lists of the two directories, and the file content, using something like this:
Code:
diff -U0 <(
  cd head1
  find * -type f | sort | xargs -r cksum ) <(
  cd head2
  find * -type f | sort | xargs -r cksum ) | while read  diff_ind  cksum  sz  path
do
 case "$diff_ind" in
 (-)
  echo "Deleted file '$path'."
  ;;
 (+)
  echo "New file '$path':"
  cat head2/$path
  ;;
 (*)
  echo "Changed file '$path':"
  sdiff head1/$path head2/$path
  ;;
 esac
done

For stricter delete/new checking, use 'comm' not 'diff -U0' but no '| xargs -r cksum' until later, when you know both are present (no tab prefix is delete, one tab is new, two tabs is both). You can report new/delete on stderr and pipe others to stdout to cksum to another while read to compare cksums before running an sdiff.
