      echo string1 > file
      echo string2 >> file
      echo string3 >> file

      ought to work, _except_ when the string is (ignoring case) ON OFF or
      empty (in which case you will set, clear or display the echo on/off
      setting instead of writing / appending to the file). People were using
      it in batch files in Dos from time immemorial, with shells which didn't
      know about inline documents.

      Best regards,
