Well, for the first one, "du | sort -n" with a few options does the
trick.

For the latter, a simple report can be made by the arbitron program, or
for a more detailed report, the "arbit" program can be used.  The source
for arbit is part of the dynafeed package in uunet:~/ClariNet/dynafeed.tar.Z

Arbit will tell you counts of who is reading what, who is subscribing to
what, how long it's been since the group got a message, and how many
users & sites you feed are subscribing to a group.   Arbit also produces
arbitron style output, or output suitable for sending to your feed site
to control your subscription group-by-group.

You can mail comments and bug reports to me.  I will send the system
to comp.sources.misc soon.
