A simple Ruby script for downloading a certain jquery version from google CND. i.e. "ruby jget.rb 2.0.0" would download 2.0.0 to jquery.min.js

jget.rb

require('open-uri')

class JGet
     def self.GetVersion(ver)
         script = '';
        open('http://ajax.googleapis.com/ajax/libs/jquery/'+ver +'/jquery.min.js') do |f|
            f.each_line{|line| script << line}
        end
        return script
    end
end

begin
    ver = ARGV[0]
    File.open('jquery.min.js', 'w') do |f|
        f.write JGet.GetVersion(ver)
    end
    puts 'Successfully downloaded version ' + ver
rescue
    puts 'Version ' + ver + ' Not Found'
end
