Hi DV, Try like this,

#!/usr/bin/perl
use warnings;
use strict;
use Net::FTP;
use Cwd;

$|++;    # Autoflush

my $server    = "172.146.140.140";
my $username  = "test";
my $pass      = "test";
my $ftp;

print "Connecting to $server..";

# Set up connection
$ftp = Net::FTP->new( $server, Passive => 1, Debug => 0 ) or die $@;
print "..authenticating..";

# Log in...
$ftp->login( $username, $pass ) or die $ftp->message;
print "..done!\n";

my @transferFileList = glob "*.log";

print $ftp->pwd (), "\n";
$ftp->cwd('somefolder') or die $ftp->message;
print $ftp->pwd (), "\n";
$ftp->binary();

for (@transferFileList){
    print "$_\n";
    $ftp->put(cwd . "\\$_") or die $ftp->message;
}

print "Logging out..";
$ftp->quit or die $ftp->message;
print "..done!\n";

1. The glob function will listout the files name only(without path).

2. No need to connect ftp for each and every file.

3. Always use pragma (strict and warnings).
