emacs: kill a buffer and remove it from the buffer list

Question

In Emacs, when a buffer is killed, it is still displayed on the buffer list (though it's empty after opening it from the list). Is is possible to remove the buffer from the buffer list?

Answer 1

You can define a function to achieve it automatically:

(defun my-kill-buffer ()
  (interactive)
  (kill-buffer)
  (if (get-buffer "*Buffer List*")
      (save-excursion
        (set-buffer "*Buffer List*")
        (revert-buffer))
))

Answer 2

Just refresh the buffer list by pressing g.
