Hi,

Do any system admins have a utility lying around to
compute some sort of weighted average summary of
file size and age?

Our cluster home space needs some cleaning and I suspect
some of the files folks are keeping on there are quite old
and would like to drive the point home with more than
just a `du -h /users/*` listing.

So something like,

  User   Usage  <Age>  Hog score

  kleb   102GB   195   19.9GB-Kdays
  frank   56GB    32    1.8GB-Kdays
  hamly  354GB   454  160.7GB-Kdays

where <Age> is the average age in days, something like,

  sum( file.size * file.age ) / ( total_size * total_age )

and Hog Score is Usage x <Age> in GB-kilodays.

Later,
