Specifically removing the "use strict" will get rid of the problem but better people than I will tell you why it should remain there.

I've split on ';'

1. You've not set $destination anywhere
2. The $ftp assignment was erroneously using the $ftp in the error message. If the connectr fails, you don't have an $ftp set, and hence cannot use it's methods.

#!/usr/local/bin/perl
use strict;
use warnings;
use Net::FTP;
use Net::Netrc;
my $server="x.x.x.x";
my $file="/home/tapas/test.txt";
my $destination = "/pub/foo/bar/baz";
my $ftp = Net::FTP->new ($server, Timeout => 9000,Debug => 3);
$ftp die "$server: cannot connect: $@";
$ftp->login or die "login: " .$ftp->message;
$ftp->binary or die "binary: ".$ftp->message;
$ftp->cwd ($destination) or die "cd $destination: ".$ftp->message;
open my $fh, "<:utf8", $file or die "open $file: $!";
$ftp->put ($fh, $file); # must give remote name.
close $fh or die "Cannot close file\n";
$ftp-quit;

Mark, getting rid of 'use strict' is never ever going to solve the problem. It just hides the errors and will die on run-time.

_I_ am the one going to say: Never ever write scripts that should last without use strict and use warnings, and never remove these to get rid of (annoying) messages. It is far more likely that you made an error^Wtypo.

If you have an error of connection in this line :
my $ftp = Net::FTP->new ($server, Timeout => 9000,Debug => 3) or die "$server: cannot connect: " .$ftp->message;
You are trying to die with a message including $ftp->message, where $ftp is undefined...

This is the first thing I see, but it can be something else.

Fred

procura,

Indeed you were the person I was referring to and hoped that it would be you explaining the error of my ways :)

See you later should beepz ever return!

Hi Procura,

I am getting below error message while compiling. Line 17 is $ftp die "$server: cannot connect:$@";

syntax error at ftp.pl line 17, near "$ftp die"
Execution of ftp.pl aborted due to compilation errors.

Stupid cut-n-paste ...

$ftp or die "FTP: cannot connect";

or something like that. The or was dropped somehow.

Enjoy, Have FUN! H.Merijn
