问题
When I use dired mode to browse around and find a file I want to open in Emacs, dired opens a new buffer for each directory I visit when looking for the file each time I select a directory with Enter, which means I can end up with a lot of buffers I don't want:
. * newer 0 Fundamental c:/work/stackoverflow/batch/mydir/newer
% mydir 302 Dired by name c:/work/stackoverflow/batch/mydir/
% batch 616 Dired by name c:/work/stackoverflow/batch/
% stackoverflow 1017 Dired by name c:/work/stackoverflow/
% work 2545 Dired by name c:/work/
* *scratch* 190 Lisp Interaction
% *Completions* 162 Completion List
* *Messages* 2163 Fundamental
Is there any way to make dired re-use a single buffer? I tried M-x customize-group for group dired but didn't see anything promising in there.
Alternatively, does anyone have a macro to close all open dired buffers?
回答1:
Use a (dired-find-alternate-file) instead of Enter

回答2:
When browsing in dired instead of hitting enter to see a directory use i then it adds that directory to the current buffer.

I've never managed to get toggle-dired-find-file-reuse-dir to work reliably - I still end up with a variety of dired buffers open, and I'm never quite sure how.
Recently I discovered dired-single (http://www.emacswiki.org/cgi-bin/wiki/dired-single.el) which seems to work better for me. If you want it guarantees a single dired buffer, and also has a nice command dired-single-magic-buffer which will take you to the open dired buffer if you have one, and opens one if you don't.
There are some other alternatives if it isn't the multiple dired buffers per se that annoy, so much as the way they pollute your buffer lists. For example, elscreen.el has a dired plugin that keeps the dired buffers in their own tab, and the excellent ibuffer mode allows you to group dired buffers together when you list buffers.
Hope that helps!

Dired+ lets you do this optionally, and it lets you toggle it on/off anytime.

;; Make dired open in the same window when using RET or ^
(put 'dired-find-alternate-file 'disabled nil) ; disables warning
(define-key dired-mode-map (kbd "RET") 'dired-find-alternate-file) ; was dired-advertised-find-file
(define-key dired-mode-map (kbd "^") (lambda () (interactive) (find-alternate-file ".."))) ; was dired-up-directory

dired-x allows this - do M-x customize-group dired-x and set 'Dired Find Subdir' to on
