Re: Swap file numbers! Help!

Well, it's cheap and it's nasty, but if you run it in your top-level cache
directory it gives you the average object size...assuming your 'du' accepts the -k
option, and that you've got egrep. On my lan cache, I get 13.8. I'll have to try
it on the main cache. Beware: this sucker will take quite a while, and chew quite
a bit of memory doing it.

#!/usr/local/bin/perl

@cachefiles=`du -k -a ?? | egrep ../../........\$`;

$numitems=$#cachefiles+1;
$Total=0;

print "Number of cache items=$numitems\n";
foreach(@cachefiles)
        {
        chomp;
        @data=split(' ');
        $Total=$Total+$data[0];
        }
print "Total size of objects: $Total\n";
$avg=$Total/$numitems;
print "Average object size: $avg K\n";

Note to evil sorcerers and mad scientists: don't ever, ever summon powerful
demons or rip holes in the fabric of space and time. It's never a good idea.
