It looks like you re running this on Windows  given your H   log txt file path    Try using  r n instead of just  n   Honestly   n is fine  you re probably viewing the log file in notepad or something else that doesn t render non-Windows newlines  Try opening it in a different viewer editor  e g  Wordpad

Use the os EOL constant instead   var os   require  os     function processInput   text             fs open  H   log txt    a   666  function  e  id        fs write  id  text   os EOL  null   utf8   function        fs close id  function         console log  file is updated
