you probably want something like

   fortytwo :~ > cat a.rb
   require 'rbconfig'
   require 'tempfile'

   def console command
     arch = Config::CONFIG['arch']

     unless arch =~ %r/win/i
       tmp = Tempfile.new Process.pid.to_s
       tmp << command
       tmp << "\n"
       tmp << "bash"
       tmp << "\n"
       tmp.close
       begin
         system "xterm -e 'bash -l -i #{ tmp.path }'"
       ensure
         tmp.close!
       end
     else
       raise 'windoze'
     end
   end

   console 'date'


i'll leave the windoze bit to you ;-)
