The messages may have been eliminated because stderr has been
redirected to /dev/null.

I think the portable shell way is to:

  # somewhere at the top, copy stdout into some unused FD
  # to be safe, assume shells cannot handle 2-digit FDs
  exec 9>&1

  # open output file
  exec 1> /foo/bar

  # ...

  # done with output file, close by restoring stdout
  exec 1>&9
