dired: goto directory of a file

dired: goto directory of a file

[leo]

hi there

in a dired buffer (particu;ar in a dired-find buffer) it would be very
handy to be able to jump to the containing directory of a file:

eg. the dired buffer shows the line

  -rw-r--r--  1 leo  staff  618385 30 Nov 08:29 Audio/Apps/iCDc4.3.3.dmg.sit

then just jump to the directory Audio/Apps in a new dired window.

cheers, leo

I came up with the following function which works in most cases I
guess:

(defun dired-open-containing-directory ()
  "Opens the directory where the file at point is located"
  (interactive)
  (let ((file (dired-filename-at-point)))
    (string-match "\\(.*/\\)" file)
    (find-file (substring file 0 (match-end 1)))))

Enjoy!

If there is some shorter/better way to extract the path from the full
filename and path, the function could be even shorter, but I didn't
find any function that does that.

C-h f file-name-directory


It's described in detail in the File Name Components node of the Emacs
Lisp manual; you might also want to browse the other subnodes of the
File Names node.

thanks. i have tried this and it works in dired-find buffers but
unfortunatly not in dired subdirs:

dired-filename-at-point doesn't work correctly in subdirs. eg the buffer
shows something like

  c:/_home:
  total 17  free 6651216
  drwxrwxrwx        0 Jan 15 15:13 .
  drwxrwxrwx        0 Jan  1  1970 ..
  drwxrwxrwx        0 Jan  6 16:24 emacs
  [...]

  c:/_home/emacs:
  total 3
  drwxrwxrwx        0 Jan  6 16:24 .
  drwxrwxrwx        0 Jan 15 15:13 ..
  drwxrwxrwx        0 Jan 15 17:41 user-lisp
  [...]

  c:/_home/emacs/user-lisp:
  total 36
  drwxrwxrwx        0 Jan 16 09:23 .
  drwxrwxrwx        0 Jan  6 16:24 ..
  -rw-rw-rw-     4922 Jan 15 17:41 leo-frames.el

now i set the point to the line with leo-frames.el, then
`dired-filename-at-point' tells me c:/_home/leo-frames.el. that's obviously
wrong.

any idea?

Use the the dired-current-directory function (and you won't even have to strip
off "leo-frames.el" to get the directory name).

You can do RET on the file and then use dired-jump.  (dired-jump is
part of dired-x.  C-x j might be a good binding for it, as
jump-to-register is also available as C-x r j.)
