hi

I need HELP to change this perl script.
Jarich is an excellent programmer and she helped me a lot before.
this script is looking for and opens this INFO text file:
...................................
FILE1 NN20000610
FILE2 ZZ20000610
...................................
renames the first file from FILE1 to NN20000610, sends it via ftp to the remote_directory_1,
waits 20 minutes,
renames the second filr from FILE2 to ZZ20000610 ans sends via ftp to the remote_directory_2

it works well,but my really problem is I cannot send a second file, if the first file was not processed.
that means, if the first file will be processed correctly,it should disappear on the remote server within 10-15 minutes.

I need to change this script, after the first file was sent:
- wait 20 minutes
- try to download via ftp the first file from the remote server (from remote_directory_1)
- if the first file is still there (not processed) don't send the second file and close the program
- but if the first file is not there (it was processed correctly), send the second file immediately.

#!/usr/bin/perl -w

my $server = "192.168.0.10";
my $user = "myuser";
my $password = "mypassword";

# ftp directories
my $remote_directory_1 = "/FTP/DATA1";
my $remote_directory_2 = "/FTP/DATA2";

chdir "/ftp/IN" or die "/ftp/IN: $!\n";
-f "/ftp/IN/INFO" or die "NO INFO FILE NO TRANSFER !\n";

my @ftp_locations = ($remote_directory_1, $remote_directory_2);

# open the file safely or complain it wouldn't open
open(FILE, "<", "INFO") or die "Failed to open info file: $!";

# read all the lines in from INFO file
my @files;
for(my $i = 1; $i <= @ftp_locations; $i++) {
        $_ = <FILE>;

        s/\W*$//;            # remove trailing whitespace
        next if (!$_);       # skip empty lines

              # check that we get our match.  If not,
              # complain and move on.  Want to see two
              # filenames.
       unless(/^([\w.-]+) \s+ ([\w.-]+)$/x) {
                print STDERR "$_ is not a valid line";
                next;
        }

        # rename the files as per rename in file
        my ($old, $new) = ($1, $2);

        unless( -e $old ) {
                print STDERR "$old does not exist!\n";
                next;
        }
        rename $old, $new;

        push @files, $new;
}

# check that we have the number of files that we expect
unless(@files == @ftp_locations) {
      die "Not enough specified ftp_locations for ".
          "given number of files!";
}

# FTP each file across, die on errors
foreach my $new (@files) {
       my $destination = shift @ftp_locations;

# ftp transfer
        my $ftp = Net::FTP->new ($server, Timeout => 9000, Debug => 3)
+;
        $ftp or die "$server: cannot connect: $@";
        # If you don't use ~/.netrc
        $ftp->login ($user,$password)
            or die "$_: cannot logon: " . $ftp->message;
        # change remote directory for the first file
        $ftp->cwd($destination);
        # Send file to ftp server
        $ftp->put($new) or
        die "$server: cannot put $new: " . $ftp->message;
        #Quit FTP When finished
        $ftp->quit;

        # Sleep for 20 minutes before processing next file.
          sleep (20 * 60)
}

if someone has time and can help me to solve this problem I'll be very happy.
greetings !
