Using Net::FTP as my network transport component, I have a situation where I will have a file on my local machine. Call it 0613x86.exe. I go to an ftp site and want to figure out if there is a newer file (perhaps 0615x86.exe). While this sounds easy, I am having a hell of a time getting the mmdd (Filename) out of the arrays and files, then doing the comparison as far as which is the newer file. I have had some help getting this far and feel close but just need a little extra code. Thanks very much, I am trying hard to learn Perl on my own, but I am really struggling with files, arrays, regex, and how Perl wants those items expressed. 
#!/usr/local/bin/perl -w
use Net::FTP;
$host = 'www.ftp.com';
$user = 'anonymous';
$pass = 'updatepuller@ftp.com';
$remote_dir = '/path/to/remote/filesendinginmmddx86.exe';
$oldfilename = `ls current-sig`;
chomp $oldfilename;
$destination_dir= "current-sig";
$ftp = Net::FTP->new($host, Debug => 1);
$ftp->login($user,$pass);
my @listing = $ftp->ls("$remote_dir");
for (@listing) {
    if ( /x86\.exe/i )  {
  open(FH, ">> myfile.txt") || die "Can't open $file for write: $!";
print FH "$_\n"
               }
                        }
close FH;
#$ftp->get("$remote_dir/$filename","$destination_dir/$filename");
$ftp->pasv();
$ftp->quit;
open( OUT, "> myfile.new") or die "$!";
open( NFH, "myfile.txt") or die( "Cannot open file : $!" ) ;
while (<NFH>) {
#($month,$day) =~ /(\d\d)(\d\d)x86\.exe/
#    m/([0-9][0-9][0-9][0-9])/;
    print( OUT "$1\n" );
               }
#close NFH or die( "Cannot close file: $!" );
#close OUT or die( "Cannot close file: $!" );
#open( NEWTIMES, "<myfile.new") or die "$!";
#while ( <NEWTIMES> ) {
#      m/([0-9][0-9])/;
#    @month = ("$1\n") ;
#                     }
#while ( <NEWTIMES> ) {
#      s/([0-9][0-9])//;
#      @day = ("$1\n") ;
#                     }
#close NEWTIMES or die( "Cannot close file: $!" );
