Review your 'ls -lh' output; what's 100Bananas + 10Kiwifruit + 1Melon?
$ find . -type f -exec ls -lh {} \; | awk '{j += $5} END {print j"M"}'

Took several minutes to come up with the wrong answer :)
$ /root/bin/dirsize .
6906276646
Took 2.75 seconds, giving actual total of the file sizes.
$ du -d0 .
6781976 .
Took 1.5 seconds, and comes to 69447434424, ie bytes allocated for those
files. All on a 300MHz Celeron.
