Update: Updated the code to a compilable verison as suggested
I am trying to get the list of latest files in each dir(for each project) under a specific path ($output) , excluding a single dir OLD
How can I frame a rule to achieve this? 
 use strict;
use warnings;
use Data::Dump;
use File::Find::Rule;
my $output = "/abc/def/ghi";
my @exclude_dirs = qw(OLD);
my $rule = File::Find::Rule->new; $rule->or($rule->new
           ->file()
           ->name(@exclude_dirs)
           ->prune
           ->discard,
      $rule->new);
my @files = $rule->in("$output");
dd \@files;
