On Ruby on Rails, where is "commands/server" which is required by script/server?

Question

Rails's script/server is just a few lines:

#!/usr/bin/env ruby
require File.expand_path('../../config/boot',  __FILE__)
require 'commands/server'

I wonder where the server file is? I tried a

find . -name 'server.*' 
find . -name 'server' 

but can't find it

Answer 1

You have to look for the files in your related gem repo. Your Ruby is located at

which ruby

Your Rails gem is

bundle show rails

You can go to the dir with

cd `bundle show rails`/lib/commands

Then, open server.rb

Answer 2

In linux they are more likely to be under

/usr/lib/ruby/gems/ruby_version/gems/rails_version/lib/commands

ruby_version and rails_version depends on which versions you are using. The directory structure will also depend on whether or not you are using rvm, but hopefully you can find your way once you get to the /usr/lib/ruby/ directory

Answer 3

thanks. in the case of a Mac, I found that they are on

/Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/commands/server.rb
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/commands/server.rb
/Users/peter/.gem/ruby/1.8/gems/rails-2.3.5/lib/commands/server.rb

the following are there but doesn't have my Rails 2.3.5 version:

/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-1.2.6/lib/commands/server.rb       
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/commands/server.rb

Update: Now the question is: which of the above 3 is the one? How can you tell easily?
