dired shell command on background

dired shell command on background

[rodrigo lazo]

hi everybody,

how could I make dired to execute a shell command on a file on the
background. Until now I was doing it with

X (dired-do-shell-command)
xpdf * &

But there must be a better way. I've seen something called
dired-do-background-shell-command on some pages about tree-dired but I
have no idea what it is about

Best regards

How about this: you augment for GNU Emacs only the PATH environment  
variable by one extra directory on top, which can be done in .emacs,  
and in this extra directory you have little executable shell scripts  
for each background command you need. You type ! or X on that file or  
the marked files in the dired buffer and then enter one such script's  
name, RET. This way Emacs would find for example the xpdf shell  
script first, which has a contents à la:

	#!/bin/sh
	# some comments or description ...
	
	/usr/local/bin/xpdf "$*" &


In case of xpdf it only accepts one file name. So it might be more  
appropriate to write:

	#!/bin/sh
	# some comments or description ...
	
	while [ $# -gt 0 ]; do
	    /usr/local/bin/xpdf $1 &
	    shift
	done

I have a piece like this. Then for .pdf files, simply `X RET' will run
xpdf at the background.

(require 'dired-x)

(setq dired-guess-shell-alist-user
      '((".dvi" "xdvi")
	(".pdf" "xpdf")))

Here is what I use in my .emacs:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

(defun dired-do-shell-command-in-background (command)
  "In dired, do shell command in background on the file or directory named on this line."
  (interactive
   (list (dired-read-shell-command (concat "& on " "%s: ") nil (list (dired-get-filename)))))
  (call-process command nil 0 nil (dired-get-filename)))

(add-hook 'dired-load-hook
	  (function (lambda ()
		      (load "dired-x")
		      (define-key dired-mode-map "&" 'dired-do-shell-command-in-background))))

(setq dired-guess-shell-alist-user
      (list (list "\\.wav$" "snack") (list "\\.au$" "snack") (list "\\.pdf$" "acroread")
	    (list "\\.doc$" "OOo" ) (list "\\.xls$" "OOo")))

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Once in dired-mode over e.g. a PDF file press '&' and proceed.

Josef
