                          newrest.rb 

require 'rubygems'

require 'rest_client'

require 'json'

$param = Hash.new

def retrieve

    url =  "http://localhost:3000/branches"

    resource = RestClient::Resource.new url +"/"+$param["id"]

    puts resource

    begin

        response = resource.get :content_type => :json, :accept => :json

        case response.code

        when 200

            puts response.to_s

        end

    rescue => e

  puts e

    end

end 

Here just i pass the ID  through command line  ie  ruby newrest.rb id="22". so what i need is , the above code have this

url =  "http://localhost:3000/branches"

    resource = RestClient::Resource.new url +"/"+$param["id"]

i  have to read that id value, which coming via the command line, and append that value with this URL "http://localhost:3000/branches/22"

So   resource = RestClient::Resource.new url +"/"+$param["id"]  this is the correct to get that value? or any way to get the value and append?

I don't see in the code where the method retrieve is called, so I
would not expect ruby newrest.rb to do anything.
Also I don't see how the command line value id is being loaded into
$param. Normally for ruby command line args I use ARGV or
OptionParser. Google for ruby command line parameters and you will
find how to do it.
