If you are interested in implementing any other functionality or website, don’t hesitate to fork the project on github. Here is the code of the Download superclass.

# The Download superclass
class Download
 attr_accessor :url, :name

 # Initializes a download
 def initialize(url, opts)
 @url = url
 @opts = opts
 @file = nil
 end

 # Tests the url
 def test
 begin
 Net::HTTP.get_response(URI.parse(url)).value
 rescue
 return false
 end
 return true
 end

 # Executes the download
 def execute
 self.set_file
 self.download
 end

 # Sets the file for the download
 def set_file
 @file = @url
 end

 # Downloads the file
 def download
 cmd = "wget -c --user-agent="#{@opts[:header]['User-Agent']}""
 cmd += " -q" if !$verbose
 cmd += " --directory-prefix="#{@opts[:dir]}"" if @opts[:dir]

 IO.popen(cmd + " #{@file}"){|f|}
 end
end

My solution: RSDownloader. It is a small ruby script I wrote to easily download any number of files from RapidShare. The script graps all the wait times directly from the site, thus optimizing your time. It starts the downloads (approximately) as soon as the countdowns reach 0. It uses wget to get the files so it is for Linux and motivated MacOSX users only. You can get the script from my github or here.

Edit: Since I keep making change to the source code, I decided to take it off this post. The latest “stable” version should always be available on my github.
