Question

Is there an Expect equivalent gem for Ruby?

I tried searching on code.google and rubygems.org, but sadly it did not show up.

FYI: Expect is a Unix automation

checkout this rubygem: https://github.com/abates/ruby_expect. It could handle some small task for you. from its official example, it's enough to 'enter password' and login and interactive with local script.

here is an example that update the git code (which is authenticated with password):

require 'rubygems'
require 'ruby_expect'

def update_code
  password = 'your password here'
  exp = RubyExpect::Expect.spawn('git pull', :debug => true)
  exp.procedure do
    each do
        expect /password: / do
            send password
        end
    end
  end
end

update_code

just run the code above, and your will see like this:

$ ruby update_code.rb 

shensiwei@gforge.1ver??.net's password:

remote: Compressing objects: 100% (84/84), done.
remote: Total 85 (delta 62), reused 0 (delta 0)
Unpacking objects: 100% (85/85), done.
