Subject: Re: expecr error help!

I even tried the passwd command code copied from this site in someone 
else's post and I get a similar error:


# ruby -d cntrlM_recycle.rbx

__CODE__

#!/usr/bin/env ruby -w

require 'pty'
require 'expect'



        print 'Old password:'
        old_pwd = gets.chomp

        print "\nNew password:"
        new_pwd = gets.chomp

        PTY.spawn('/usr/bin/passwd katty') do |read,write,pid|


          write.sync = true
          $expect_verbose = false

          # You can use regular expressions instead of strings. The code 
block
          # will give you the regex matches.
          read.expect(/Changing password for katty\nNew password: /, 5) 
do |response, *matches|


            write.print new_pwd + "\n" if response
          end

          # The default value for the timeout is 9999999 seconds
          read.expect("Re-enter new password:") do |response|
    write.puts new_pwd + "\n" if response


          end
        end
