Password Echo

[Marc Soda]

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).

enjoy,

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.
