i am writing a script that does a number os usage and space checking routines. having trouble with one of them. the plan here is to recurse thru a directory, record each uniqe user and add the size of the directories per user and then spit out a total like this:
User   Total usage in /some/dir
foo   450MB
bar   550MB
here is some code:
use File::Find;
find (\&wanted_user, "$dir");

sub wanted_user
{
        %sum = ();
        next unless (-d $_);
        ($user,$size) = (stat($_))[4,7] or die "can't stat: $!\n";
        push ( @{$sum{$user}}, $size );
}


foreach $user (sort keys %sum) {
        print "$user: @{$sum{$user}}\n";
}

----------------
questions:
1. it prints nothing. it should at least print something like 11847: 44645, 45466....
2. after question 1 is solved, what is the best way to add the size into a total.
something like: push ( @{$sum{$user}}, ++$size ); ?
3. also I may have to get rid of the stat() way of getting the user and size because there are some dirs that have dirs and files that i do not have access too and will generate erros instead of stating. i know i can parse a `ls -ld` but is there a better way? Thanks for any help Jim
