This is not what you are looking for, but ...

Several years ago, I wrote a program which would take the output from
`ls -lR` of whatever, for each file or directory calculate the rolled-up
size (meaning for a directory the recursive total size of all its
contents), and sort the result by descending rolled-up size.  The
resulting list was enormous, but generally it was not hard to the
interesting bits:  you would ignore the first few lines (you already
know that / is going to be big, don't you?), and after some number of
further lines you are down to numbers small enough that you don't care
to read any further.

I have not tried to use this for a long time, as I have been able to buy
enough lotsabytes of disk to meet my needs.  If anybody cares, I shall
see what I can resurrect.

Cheers,
Terry.
