Currently, I'm running each my Selenium Ruby Webdriver script (\*.rb) on Ruby command prompt window with the syntax, ex: ruby test.rb. It works well.

However, I also have some other scripts and now I want to run all scripts once instead of calling ruby test1.rb, then wait for this script done, then continue to run: ruby test2.rb.....then, ruby test3.rb.....

Anybody please guide me a way to run all scripts I created at a time? Thanks so much.
