Okay, so as you indicate, this is complicated and difficult to explain -- worse to have to type it out. I empathize -- truly.

So naturally the first thing I need to do is get into your headspace -- easiest way is to take your data and code and run it to get a feel for what it is trying to do.

So I wrapped your code in a subroutine (mainly to isolate my code from yours) and called it.

Either you didn't give me everything, or something is seriously wrong with your code:

#!/usr/bin/perl -w

use strict;

foreach my $configFilename (@ARGV)
{
    if (open FH, '<', $configFilename)
    {
        &processConfigFile();
    }
}

exit;

__END__

So we'll need to get past this before I'm going to be of much use to you.

The full code I used is here so we can compare apples to apples as we work through this:

#!/usr/bin/perl -w

use strict;

foreach my $configFilename (@ARGV)
{
    if (open FH, '<', $configFilename)
    {
        &processConfigFile();
    }
}

exit;


sub processConfigFile
{

while( $line = <FH>)
        {
            next unless $line =~ m<\s+(\S+)\sHOLDS\s(.+)>x;
            $key = $1; #Obtains first_distribution, etc

            if ($line =~ /(\S+_Lower)\sHOLDS\s\S+/i)
            {
                $base_type = $1;  #obtains parent config ID (eg SWG_Lo
+wer )

                while ($line =~ m<\s(\S+):\s(completion).+>gx)  # obta
+ining attributes
                {
                    push(@{$base{$base_type}}, $1);}}  # push each att
+ribute associated with parent ID into an hash of arrays
                         # eg A dump from the hash looks like this whi
+ch is correct  SWG_Lower:: total_dist total_finish  total_cancel
                                                                 LOADE
+D_Lower:: total_finish, total_cancel
                              :                                 CONFIG
+_Lower: total_cancel

            next unless exists $results{$key}; # I do this incase ther
+e are distribution ids in the file which are not in my hash
}


__END__
