Runner runs Ruby code in the context of Rails non-interactively.

From rails runner command:

Usage: runner [options] ('Some.ruby(code)' or a filename)

    -e, --environment=name           Specifies the environment for the runner to operate under (test/development/production).
                                     Default: development

    -h, --help                       Show this help message.

You can also use runner as a shebang line for your scripts like this:

#!/usr/bin/env /Users/me/rails_project/script/rails runner

Product.all.each { |p| p.price *= 2 ; p.save! }
