Hey. I'm currently making a script to read a directory, store the file size and name, scan for any duplicates and delete one of the duplicate pair. I came up with this code, which is supposed to print out the sizes of duplicates (very rough code): 
#!/usr/bin/perl
use strict;
use warnings;

my $dir = shift();
my @images;

opendir(DIR, $dir) or die("Couldn't open dir $dir: $!");
foreach my $file_found (readdir(DIR))
    {
    my %image;
    $image{name} = $file_found;
    $image{size} = (stat("$dir/$file_found"))[7];
    push @images, \%image;
    }
closedir(DIR);

my $previous = 'bo mix';
my @duplicates = grep $_ eq $previous && ($_ = %{$_}) && ($_ = $_{size
+}) && ($previous = $_), @images;
print join ', ', @duplicates;

That produces no output on a dir which I know contains files of duplicate sizes. Not surprising, considering that that grep feels absolutely horrible. But is there a way to do that horrible grep in a better (and working) way? Because I think the code's okay up to there.
