Oh .. i thought that was right..now i tried with

class CheckController < ApplicationController
  def index
    time = Time.now
    @time = time
    @dr = ` dir `
  end
end

... but in vain still that " Application error (Rails)" is bugging me.

any lead?

btw .. what is the best way to  debug rails application

thanks
