Here's how I did it using Term::Readkey

ReadMode ('noecho');
print "Enter Password: ";
chomp($pw = <STDIN>);
ReadMode ('restore');

    Another methood is this:
    system('stty -echo'); print "Enter Password: "; chomp($pw = <STDIN>); system('stty echo');

    The computer can't tell you the emotional story. It can give you the exact mathematical design, but what's missing is the eyebrows. - Frank Zappa

       This works but there are two caveats you should bear in mind:

      • If you're running the script as a priviledged process you might have just opened yourself to a local attack, if the user can modify their path and slip in a trojan 'stty' binary.
      • This fails utterly on Windows, amongst other systems.
