The PERL Cookbook seems to have the answer.


You want to read input from the keyboard without the keystrokes being  
echoed on the screen. For instance, you want to read passwords as passwd  
does, i.e. without displaying the user's password.

Use the CPAN module Term::ReadKey, set the input mode to noecho, and then  
use ReadLine:

use Term::ReadKey;

$password = ReadLine(0);
