Simple du(1) wrapper that lists directory sizes. It will try to get the disk usage for all directories in the given directory ("." if not given), sort the result by size in bytes, and print it in a human readable way.
Example to get top ten directories in "Library":
> dusage Library | tail
868.00K Library/Keychains
2.89M Library/Preferences
4.39M Library/Logs
5.31M Library/Safari
7.62M Library/Saved Application State
26.24M Library/Calendars
55.94M Library/Containers
95.50M Library/Application Support
1.19G Library/Caches
