'uniq' seems more appropriate for this task than diff. With '-u' it will
list only those lines which are only listed once.

(find / ; cat /var/lib/dpkg/info/*.list) | sort | uniq -u


PS: Jason, start reading the man pages and info documents for shellutils,
textutils, and fileutils.  many of the really useful basic unix tools are
documented there.  see also /usr/doc/ directories for same.  enjoy!

If you haven't already installed it, install the dwww package. it allows
you to use a web browser like netscape or lynx to browse all system
documentation, including man pages, info pages, and the /usr/doc
subdirectories.  dwww really is the best thing since sliced bread (or
debian...whichever tastes better to you :-).  You will also need to
install a web server like apache, and the info2www and man2html packages.
