Please help me sort out the following problem: I have to compare (bitwise) files in two directories and if there is found atleast one single file not present in the other directory, then the comparison fails and program aborts. (The two directories names needs to be supplied as arguments at command line) I have the following solution:

    use strict;
    use warnings;
    use File::Find;
    use File::Compare;
    #use Data::Dumper;
    my $dir1 = '/home/khan/Desktop/dir2';
    my $dir2 = '/home/khan/Desktop/dir1';
    my %dir = ();
    my $file='';

    find(\&wanted, $dir1,$dir2);
     
    sub wanted {
       my $f = $File::Find::name;
      next if $File::Find::name =~ /^\.{1,2}$/;
       $f =~ s/^($dir1|$dir2)//o;
       $dir{$1}{$f}++; # create a hash for each parent
       $dir{$f}++; # count all files in both parents
    }
     foreach my $parent ($dir1, $dir2) {
       foreach my $file ( sort keys %{$dir{$parent} } ) 
    { print "Failed" if ($dir{$file} == 1); }
   }
