HighLine can take care of this for you.

    > cat password.rb 
    require "rubygems"
    require "highline/import"

    pass = ask("Enter your password:  ") { |q| q.echo = '*' }
    puts "Your password is `#{pass}'!"

    > ruby password.rb
    Enter your password:  ********************************************
    Your password is `This is how you do a password prompt in ruby'!

If you set q.echo = false then you will have nothing echoed on the
terminal.

If you want to roll your own on *nix boxes, you'll need to become
familiar with stty(1).

enjoy,
