Thanks almet for ftp idea. Same, I got inputs from the node http://www.perlmonks.org/?node_id=539261 for SFTP. I got the files what i need from the directory using $sftp->ls.

my %args = (user => encode("iso-8859-1", $ftp_user) , password => enco
+de("iso-8859-1", $ftp_passwd));
        $args{ssh_args}  = [ port => encode("iso-8859-1", $ftp_port) ]
+ if $ftp_port;
        $sftp = Net::SFTP->new($ftp_url, %args);
        return 0 if (!$sftp);
        $sftp->ls($ftp_additional_path, sub { my $ref = shift;
                                              if ($ref->{'filename'} =
+~ /_3rdParty_/) {
                                                  $files->{$ref->{'fil
+ename'}} = 1
                                            }
        });
        print (keys %{$files});
        
        $sftp->get(encode("iso-8859-1", $ftp_file), $local_file);
        my ($statuscode, $statustext) = $sftp->status;
        $log->error("\nFile not found") if($statustext ne "No error");
