I have a script in my lib/config/my_script.rb which make a synchronization from MAIN database to m开发者_StackOverflow社区y Database. How i can run it from command line? And it will be working?

 ruby my_script.rb

I also wanted to provide a Ruby quick reference guide that will give you additional information on command line arguments for the ruby command as well as a wealth of other information on Ruby.
