Execute In Multiple Shells?

Execute In Multiple Shells?

[gamename]

Hi,

How can I send the same command to multiple shell buffers at the same
time?  That is, if I have 5 bash shells running, how can I send
"source ./.bash" to all of them at once?

Thanks,
-T

(require 'cl)

(defvar buffer-name-map   nil)
(defvar buffer-list-cache nil)

(defun buffer-named (name)
  "
RETURN: the buffer which has as name `name'.
"
  (let ((bl (buffer-list)))
    (unless (and buffer-list-cache buffer-name-map
                 (equal buffer-list-cache bl))
      (setf buffer-list-cache (copy-seq bl))
      (setf buffer-name-map (make-hash-table :test (function equal)))
      (dolist (buffer buffer-list-cache)
        (let ((name (buffer-name buffer)))
          (when name (setf (gethash name buffer-name-map) buffer)))
        (let ((name (buffer-file-name buffer)))
          (when name (setf (gethash name buffer-name-map) buffer))))))
  (or (gethash name buffer-name-map)
      (gethash (truename name) buffer-name-map)))



(defun mapshell (command shell-buffers)
   (dolist (shell shell-buffers)
     (with-current-buffer (etypecase shell
                            (string (buffer-named shell))
                            (buffer shell)
                            (process (process-buffer shell)))
        (if (char= (aref "\n" 0) (aref command (1- (length command))))
           (comint-send-string (current-buffer) command)
           (comint-send-string (current-buffer) (format "%s\n" command))))))


(mapshell "echo hello\n" (list  "0shell"  "1shell"))

How is this different from `get-buffer`?

It uses truename, which I forgot to adjoin:


(defun truename (filespec)
  "
RETURN:  The absolute path name corresponding to fielspec.
"
  (car (file-expand-wildcards (shell-quote-argument filespec) t)))

The latter can easily be put into ~/.emacs_bash...
