Hi, Its been about 3 years since I wrote Perl code and I have seem to forgot the little that I knew. I wrote something to search 2 directories and compare the files and copy any files that exist in the other. It works but not like how I want it to. For some reason it copies all the files every time when it is suppose to only copy the files directory 2 does not have. Im assuming it has something to do with the map function. I am using ActivePerl for my development. The code is below, any help would be greatly appreciated. Thanks in advance! 
use Class::Date qw(:errors date localdate gmdate now);


# Check system date for filename
$date = localdate(time); 
$date->monname;
$date->yr;
$month = substr($date->monname,0,3);
$file_name = $month . $date->yr . "BU";


# Opens log to write to
open (MYFILE, '>>c:\\Perl scripts\\TEST1.log');

# Opens source directory and compares all files to all the files  - If
+ new files, it copies it to 2nd location
opendir (DIR1, "C:\\TEST1") or die print MYFILE "Today is $date \n Cou
+ldn't open directory, C:\\TEST1";
while ($file1 = readdir DIR1)
{
  #print "$file1 \n";
  push(@files1, $file1);
}

#print "@files1 \n";

closedir DIR1;

#opendir (DIR2, "C:\\TEST2") or die print MYFILE "Today is $date \n Co
+uldn't open directory, C:\\TEST2";
while ($file2 = readdir DIR2)
{
  #print "$file2 \n";
  push(@files2, $file2);
}


#print "@files2 \n";

closedir DIR2;


#Compares the directories and copies the missing files to the other di
+rectory
%temp = map {$_,$_} @files2;
for(@files1) {
   next if exists $temp{$_};
   system("copy C:\\TEST1\\$_ C:\\TEST2\\");
   print MYFILE "$_ has been copied\n";
   
}

close(MYFILE);
