------------------------------------------------------------------ IO#<<
      ios << obj     => ios
------------------------------------------------------------------------
      String Output---Writes obj to ios. obj will be converted to a
      string using to_s.

         $stdout << "Hello " << "world!\n"

      produces:

         Hello world!

As you can see, << is more like write or print than puts, while echo  
will append a new line

try file.puts "Test" and see if your file sizes match up then
