Hi Toolic!
The code is part of a larger program that uses two subroutines
that allow me to copy files based on time and
then match them with the dir that have the same id at the beginning of the id string.

#!/usr/bin/perl
use strict;
use DateTime;
use File::Copy;
use File::Find;
use File::stat;
use Time::localtime;


my $now = DateTime->now(time_zone => 'floating');
my $yesterday = $now->subtract(days=>1);
my $year = $yesterday->year;
my $month = $yesterday->month;
my $month_abbr = uc($yesterday->month_abbr);# uppercase string chars
my $day = $yesterday->day;
my $year_abbr = substr "$year",2,2;
my $mdy = $now->strftime("%m-%d-%y");

print "$year\t$year_abbr\t$month\t$month_abbr\t$day\n";
# location of files to be processed.
my $root="/Users/mgavi.brathwaite/Desktop/BioinfDev/SequenceAssemblyPr
+oject/Sequencing_Results/RESULTS $year/New Version/Amanda Li/$month_a
+bbr "."$year";
print "$root\n";
# location of maid directories
my $komp_dir ="/Users/mgavi.brathwaite/Desktop/BioinfDev/SequenceAssem
+blyProject/KOMP";
my %files();
find(\&wanted, $root);

#check the arrays in the hash looking for maids with 4 files
foreach my $k (keys(%files)){
  #get the array from the array reference.
  #See how the reference gets in the has below.
  my @arr=@{$files{$k}};   
   #skip unless we have 4 files in the array                      
  next unless ( scalar my @array) == 4;  
  #look for KOMP maid directory we want to copy to
  #glob dirs with a regex something like /$k\D/ - lets call it $KOMP_d
+ir
  $komp_dir = maid_dirs($k);
  #Create the sequencing sub dir under $KOMP_dir
  #so now KOMP_dir=KOMP_dir+"/sequencing"
  mkdir $komp_dir."/sequencing",0755;
  $komp_dir=$komp_dir."/sequencing/";
  #now iterate through the array, copying the files.  You know the mai
+d number ($k)
 foreach my $f (@arr){ 
   copy("$f","$komp_dir/$f")  or die "Copy failed: $!";
 } 
    #do_phred_phrap($komp_dir);
}
=for
  sub do_phred_phrap{
    my $dir=shift;
