Running Ruby Script/Program and interacting in command line

Question

I have seen it before but I cannot remember where. I have a Ruby program that I'd like to execute and interact with in command line and call the functions. Similar to irb but within that program. For example:

class Message
  @@messages_sent = 0
  def initialize (from, to)
    @from = from
    @to = to
    @@messages_sent +=1
  end   
end
class Email < Message
  def initialize (from,to)
   super
  end
end

and I want to run the script and call functions such as

my_message = Message.new('NYC','TDOT')

How? I did the ruby myprogram.rb and just runs it and closes it, I actually want to enter into the program

You need to first require IRB and then type IRB.start where you want to start it:

require 'irb'

IRB.start
