cgi bash skripting

#!/usr/bin/env ruby

require 'webrick'

class Call < WEBrick::HTTPServlet::AbstractServlet
  def do_GET(request, response)
    action = request.query['action']
    response.status = 200
    response['Content-Type'] = 'text/html'
    response.body = 'No command given'
    if action
      response.body = IO.popen(action.to_s).readlines.join("") #.join("<br/>")
    end
  end
  alias :do_POST :do_GET
end

if $0 == __FILE__ then
  server = WEBrick::HTTPServer.new(
    :BindAddress     => 'localhost',
    :Port            => 8080,
    :Logger          => WEBrick::Log.new('server.log', WEBrick::Log::DEBUG),
    :AccessLog       => [[File.open('access.log', 'w'), WEBrick::AccessLog::COMBINED_LOG_FORMAT]]
  )
  # Required for CGI on Windows; unnecessary on Unix/Linux
  server.config.store(:CGIInterpreter, WEBrick::HTTPServlet::CGIHandler::Ruby.to_s)
  server.mount("/call", Call)
  # Trap signals so as to shutdown cleanly
  ['TERM', 'INT'].each do |signal|
    trap(signal) { server.shutdown }
  end
  # Start the server and block on input
  server.start
end

Bash wäre mir wesentlich angenehmer da es auch portabler ist.
