I need to compare the contents of two HoH. Each hash represents files from a local cluster of machines and files in a remote cluster of machines. The code below correctly populates them both, but I don't know how to access each element for comparison.

What I mean by comparison is each hash must contain the same keys and key values.

 #!/usr/bin/perl -w

use strict;
use Digest::MD5;
use Data::Dumper;


my(%localDigest, %remoteDigest );
my ($file, $md5, $digest, $key, $clusterHost);
my @files = (@ARGV);
my @hosts = ("Maleah", "Austin");

foreach $clusterHost(@hosts) 
  {    
    foreach  $file(@files) 
      {
    open(FILE, $file) or die "Can't open '$file': $!";
    binmode(FILE);
    
    $md5 = Digest::MD5->new;
    while (<FILE>) 
      {
        $md5->add($_);
        $digest = $md5->hexdigest;
        
        $localDigest{$clusterHost}{$file} = $digest;
        $remoteDigest{$clusterHost}{$file} = $digest;
      }
    close(FILE);
    
      }
  }

print Dumper (%localDigest,%remoteDigest );

Specifically, what I need to compare is, ie:

%localDigest

$VAR1 = 'Austin';
$VAR2 = {
          './gen-checksum.pl' => 'ad65a01b783248a21fcea95979a265a0',
          '/etc/passwd' => 'c978c29a59ba0138e5ed0ca325f7ec1e'
        };
$VAR3 = 'Maleah';
$VAR4 = {
          './gen-checksum.pl' => 'ad65a01b783248a21fcea95979a265a0',
          '/etc/passwd' => 'c978c29a59ba0138e5ed0ca325f7ec1e'
        };

equals

%remoteDigest

$VAR5 = 'Austin';
$VAR6 = {
          './gen-checksum.pl' => 'ad65a01b783248a21fcea95979a265a0',
          '/etc/passwd' => 'c978c29a59ba0138e5ed0ca325f7ec1e'
        };
$VAR7 = 'Maleah';
$VAR8 = {
          './gen-checksum.pl' => 'ad65a01b783248a21fcea95979a265a0',
          '/etc/passwd' => 'c978c29a59ba0138e5ed0ca325f7ec1e'
        };

Thanks, once again,

If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
