I have this function here, i'm not the author...

(defun kill-all-buffers ()
  "Kill literally all buffers. This keeps Emacs from bloating."
  (interactive)
  (if (fboundp 'gnus-group-exit) (gnus-group-exit))
  (loop for x being buffers
    do (kill-buffer x)))

Maybe something like this:?


(defun kill-major-mode-buffer (mode)
  "Kills current buffer when major mode is MODE."
  (if (eq (cdr (assoc 'major-mode (buffer-local-variables))) mode)
      (kill-buffer (current-buffer))))

(defun kill-all-major-mode-buffer (mode)
  "Kills all buffer when major mode is MODE."
  (interactive "SMode: ")
  (mapc (lambda (buffer)
            (progn
              (set-buffer buffer)
              (kill-major-mode-buffer mode))) (buffer-list)))

HTH

Another option:

C-x C-b                 ; to run "list-buffers"
kkkkkkkkkkkkkkkkk       ; to mark the buffers to be killed
x                       ; to actually kill them

Isn't here a C-x o needed?

And wouldn't C-u 99 d make more sense and by faster than the following?

This all would also kill the *scratch* buffer ...

Yes, it might be.

Probably :-)

Yup, but the OP indeed asked how to kill _all_ the buffers.

Sometimes folks don't make these fine distinctions between really all  
buffers and only all those with a major-mode ... although: doesn't it  
have Lisp Interaction-mode?

RE: how can i kill all the buffers

In Icicles:   C-x k TAB C-!

Of course, I agree with others who've said that you probably do not really
want to kill all buffers. If you don't, then use this, where <pattern> is a
regexp or a substring that matches all of the buffers you do want to kill:

C-x k <pattern> S-TAB C-!

You can see all of the matching buffer names in buffer *Completions*, and
you can modify the <pattern> if it didn't match exactly exactly what you
thought it would ;-) - the set of matches is updated on the fly. Hit `C-!'
when the matching names are those you really want.

Or use a <pattern> to match all of the buffers that you do _not_ want to
kill, and kill all the rest.  `C-~' complements the candidate set.

C-x k <pattern> S-TAB C-~ C-!

Or cycle among matching buffer candidates, killing only those you want when
you reach them. Or click `C-mouse-2' in *Completions* to selectively kill
buffers. These are all ways to manipulate the set of names that match your
input.

The same behavior applies to deleting files, using command
`icicle-delete-file'.

Your question is a generalization of "How do I kill one buffer", which is
what standard `C-x k' (`kill-buffer') does. In Icicles, commands that affect
one object can also affect many, and `C-x k' (`icicle-kill-buffer') is an
example of this.

And it is as easy to define such a multi-command as it is to define the
single-target version - the definitions are in fact the same.

I took kill-some-buffers and modified it a bit.

(defun kill-all-buffers (&optional list)
  "For each buffer in LIST, kill it. If it's been modified don't do
anything.
LIST defaults to all existing live buffers."
  (interactive)
  (if (null list)
      (setq list (buffer-list)))
  (while list
    (let* ((buffer (car list))
	   (name (buffer-name buffer)))
      (and (not (string-equal name ""))
	   (/= (aref name 0) ? )
	   (if (not (buffer-modified-p buffer)) t )
	   (kill-buffer buffer)))
    (setq list (cdr list))))

If you use ibuffer, then

bring up Ibuffer menu with      C-x C-b
mark your perl buffers with     % m perl RET
delete with                     D
confirm with                    y
