のでメモ。

　　　：                      If the file or directory has extended
     attributes, the permissions field printed by the -l option is followed by
     a '@' character.  Otherwise, if the file or directory has extended secu-
     rity information (such as an access control list), the permissions field
     printed by the -l option is followed by a '+' character.
