Running another ruby script from a ruby script

Question

In ruby, is it possible to specify to call another ruby script using the same ruby interpreter as the original script is being run by?

For example, if a.rb runs b.rb

Answer 1

This is what I have used

/myapp/script/main_script.rb

load rails env, only if you need to

ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'development'
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")

run other slave scripts from within main_script.rb

require File.expand_path(File.dirname(__FILE__) + "/../script/populate_wh_grape_varieties_table.rb")
