I've got it working, but in a very sloppy way.
I wondered if it was possible and reasonable to add a feature to du or
find, so that one can include only files with inode counter = 1.
'du' doesn't count twice:
$ mkdir d1 \
&& dd if=/dev/zero of=d1/x bs=1M count=20 status=none \
&& cp -al d1 d2
$ ls -lihog d1/x d2/x
805939 -rw-r--r-- 2 20M Oct 30 19:04 d1/x
805939 -rw-r--r-- 2 20M Oct 30 19:04 d2/x
$ du -shxc d1 d2
21M d1
4.0K d2
21M total
FWIW: find has a "-links N" option.
Does that answer your question?
Have a nice day,
Berny
