Ruby - How to run rails console commands inside ruby file?

Question

Is it possible to create a ruby script that can execute rails commands?

Like:

rails_start.rb:

Class RailsStart
    #Start rails server
    rails server
end

Why would you want to do that? – Sergio Tulentsev Jan 28 '13 at 19:15 — Sergio Tulentsev, Jan 28 '13 at 19:15

You can always shell out.

system('rails server')

or

`rails server` # backticks

Is it possible to define path to rails? So you can fire up multiple rails servers for apps. And where did you find this documentation for system? – Rails beginner Jan 28 '13 at 19:22
It's [Kernel#system](http://www.ruby-doc.org/core-1.9.3/Kernel.html#method-i-system). No, you can't fire multiple servers this way. Unless you fork or multi-thread. See also [Dir#chdir](http://www.ruby-doc.org/core-1.9.3/Dir.html#method-c-chdir) – Sergio Tulentsev Jan 28 '13 at 19:25

The easiest way is to put backticks around the command:

`rails server`

But what are you trying to do?
