Take a look at File::Find::Rule. For example

#!/usr/bin/perl
use strict;
use File::Find::Rule;
use Data::Dump 'pp';

my $path = '/abc';

my $rule =  File::Find::Rule->new;
$rule->file->name( 'result.xls' );

my %source=();
for my $filename ( $rule->in($path) ){
  my @f = split '/',$filename;
  my $mode = $f[-2];
  $source{$mode} = $filename;
};

pp \%source;
