Simple Console in RubyMine

I know that Rails Console and IRB can be run from Tools. But how can i run simple console in RubyMine? (command line for rails s; rails开发者_如何学JAVA g ... - it is more comfortable for me)

You can configure 'bash' as an external tool in Settings | External Tools - then you'll be able to run it in a RubyMine toolwindow.
