Abstract
dpkg-du is a quick little script (hack?) to produce a dump of the installed size of Debian packages in du format. For example, dpkg-du|sort -n|tail -10 will show the 10 biggest packages on your system.
Usage
There's no flags. Just dump it in /usr/local/bin or such a place, and run dpkg-du. Enjoy. It should work on any Debian box with awk installed, or any Debian derivative, such as Ubuntu.
License
Released under the BSD license. Honestly.. anyone who thinks there's commercialisable IP in a two line script - go for it.
Where is it?
