Very impressive. Made me waste a lot of time trying to beat it!

I think I've got it just a little shorter. I don't know if the time I spent on this has brought me any closer to enlightenment, but it did make me fast (as in skip a meal)... 
perl -e'%h=map{/.\s/;7**(ord$&&30)-$`,$_}`du -h`;die @h{sort %h}'

66 characters.

The key is the 7 to the power of ord(char) bitwise 30 part. I had to write a little perl script that would find the magic values 7 and 30 which would work for a lexicographic (default) sort. That is, I take 7 to the power of those values, and subtract the value of $` ... to produce hash keys which sort properly.

Then I take a hash slice on the sorted result. The sort actually returns the entire flattened hash sorted, keys and values, but since the values in that hash don't map to anything, they are silent.

I think I need to go get something to eat.

In reply to Re^6: du -h, sorted by bellaire
