I am trying to ftp into a server, once I'm there, I want to get a file, then put it back after sleeping for 5 minutes. I have that part correct, but i added to the code, two variables that will be inputted when the code is executed. The user will input the username they want to connect with. I am having trouble connecting though. When I input the username t14pb, it still goes to the the first if statement, as if I said t14pmds. here is the code:

#!/usr/bin/perl

use Net::FTP;

$host     = "fd00p02";
$username = "$ARGV[0]";
$ftpdir   = "/";
$file     = "$ARGV[1]";

print "$username\n";
print "$file\n";

if ($username == t14pmds) {

  $password = "test1";

  $ftp = Net::FTP->new($host) or die "Error connecting to $host: $!";
  $ftp->login($username, $password) or die "Login failed: $!";
  $ftp->cwd($ftpdir) or die "Can't go to $ftpdir: $!";
  $ftp->get($file) or die "Can't get $file: $!";

  sleep 5;

  $ftp->put($file) or die "Can't put $file: $!";
  $ftp->quit or die "Error closing ftp connection: $!";
}

if ($username == t14pb) {

  $password = "test2";

  $ftp = Net::FTP->new($host) or die "Error connecting to $host: $!";
  $ftp->login($username, $password) or die "Login failed: $!";
  $ftp->cwd($ftpdir) or die "Can't go to $ftpdir: $!";
  $ftp->get($file) or die "Can't get $file: $!";

  sleep 5;

  $ftp->put($file) or die "Can't put $file: $!";
  $ftp->quit or die "Error closing ftp connection: $!";
}

if ($username == t14pmds_out) {

  $password = "test3";

  $ftp = Net::FTP->new($host) or die "Error connecting to $host: $!";
  $ftp->login($username, $password) or die "Login failed: $!";
  $ftp->cwd($ftpdir) or die "Can't go to $ftpdir: $!";
  $ftp->get($file) or die "Can't get $file: $!";

  sleep 5;

  $ftp->put($file) or die "Can't put $file: $!";
  $ftp->quit or die "Error closing ftp connection: $!";
}

if ($username == t14fiserv) {

  $password = "test4";

  $ftp = Net::FTP->new($host) or die "Error connecting to $host: $!";
  $ftp->login($username, $password) or die "Login failed: $!";
  $ftp->cwd($ftpdir) or die "Can't go to $ftpdir: $!";
  $ftp->get($file) or die "Can't get $file: $!";

  sleep 5;

  $ftp->put($file) or die "Can't put $file: $!";
  $ftp->quit or die "Error closing ftp connection: $!";
}
