Hi all,
   I am using dired to navigate through the files of my home. But the
   problem is the moment i move to a subdirectory dired creates a new
   buffer for it. So ultimetly it turns out i have just too many buffers
   open if i am locating a file buried deep my home directory sturcture.
   Is there some configuration variable which shall tell it not to create 
   all these buffers but to work only from one buffer. In short all i want
   is JUST ONE buffer for all my navigation.
Regards,
K.

You can hit `a' instead of `f' or RET to open the subdir/file.

You can also try `i' on a directory.  Maybe you will like it.

Some comments regarding dired...

Dired is good for what it is, a "directory editor". But it doesn't
feel optimal as a filesystem browser. I still bust out an xterm and
use ls/cd etc. I considered a list of things that I would want in a
filesystem browser:

        * The "-l" style output should be optional
        * Hidden files should not be shown by default
        * Do not create new buffers for each dir visited
        * Navigation commands bound to single keys
        * Modeline is menu showing available operations on file

I implemented these ideas:

        http://www.theworld.com/~proteus/ec.el

After loading, do "M-x ec" to start.

 l   - Toggle -l style listing
 a   - Toggle hidden files
 n/p - Next/Previous line
 u   - Up directory
 ret - Enter directory
 g   - Jump to a directory

There are no facilities for "editing" directories, but that's just
because I was experimenting with implementing the features mentioned
above.

I don't get it.  Dired has this and lots more.

Just use `i' on the subdirectorys.

How bout trying the following steps.

   Find any directory.
   On that directory line type C-u i R
   Now, do M-$
   Now, try M-$ again.

Does this seem useful?  I find it extremely useful.

Is there a command to remove the directory you inserted with i ?

Very useful indeed.  I wasn't aware of these commands... I should pay
closer attention to the mode help.

Thanks.

Dig further into dired-do-kill-lines from the mode help.

Try `dired-do-kill-lines' which is binded on `k'.

,----[ C-h f dired-do-kill-lines RET ]
| dired-do-kill-lines is an interactive compiled Lisp function in `dired-aux'.
| (dired-do-kill-lines &optional ARG FMT)
| 
| Kill all marked lines (not the files).
| With a prefix argument, kill that many lines starting with the current line.
| (A negative argument kills lines before the current line.)
| To kill an entire subdirectory, go to its directory header line
| and use this command with a prefix argument (the value does not matter).
`----

Bye.

Someone here posted this code some years? ago

;;;; dired improvements reuse existing buffer instead of generating every-time
;;;; a new one

(require 'dired)
(defun dired-follow-file ()
  "In dired, visit the file or directory on this line.
If a directory is on the current line, replace the current
dired buffer with one containing the contents of the directory.
Otherwise, invoke `dired-find-file' on the file."
  (interactive)
  (let ((filename (dired-get-filename)))
    ;; if the file is a directory, replace the buffer with the
    ;;  directories contents
    (if (file-directory-p filename)
        (find-alternate-file filename)
      ;; otherwise simply perform a normal `dired-find-file'
      (dired-find-file))))       


with this hooks.

;;;; dired improvement
(add-hook
 'dired-mode-hook
 (lambda ()
   (local-set-key [return] 'dired-follow-file)
   (local-set-key [ e ] 'dired-follow-file)
   (local-set-key [ v ] 'dired-follow-file)
   (local-set-key [ f ] 'dired-follow-file)))

Use it to your liking.

Consider the 'i' command in dired.
