Anyone know of a way, aside from Ruby/Password, of suppressing echo
for a password prompt on a terminal?  I'm interested in *nix
primarily.

Thanks,
Marc

curses comes to mind (Curses.noecho() would suppress the echoing of the
text)

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).

ruby-termios

It's trivial with HighLine.

Thanks all.  I was hoping that there was a way I overlooked that
didn't require any external dependencies.  However, I ended up using
ruby-termios.

Marc--I use:

     begin
       system "stty -echo"
       @password = gets.chomp
     ensure
       system "stty echo"
     end

It turns off terminal echoing, ensuring that the script can't end before 
turning echoing back on.
