You might try something like:
find . -type d -exec du -s {} \;
That would give you much better output that would be more amenable to
arithmetic. du -ah gives fairly messy output in comparison. How, in
a script, do you add these up:
4.0k ./.saves-483-infidel.spots.ab.ca~
2.3M ./.jnewsrc-spots~
0 ./.saves-24502-infidel.spots.ab.ca~
4.0k ./.saves-7770-infidel.spots.ab.ca~
1.8M ./.jnewsrc-dfn~
Yes, it can be done, but not as easily.
