run shell-command in the background?

run shell-command in the background?

[Vektor]

if i use (shell-command "my-script"), the emacs will run the script
and freeze itself.
is it possible to run a shell command in the background?


ps: actually, this script is named "runmoz", it handle the "open
new-tab in an already running mozilla, otherwise start a mozilla"
stuff.

actually this is what i am doing.

the runmoz script is good so that  even i C-g when emacs freeze, the
mozilla will continue running without exit.

but "shell-command &" will do nothing good.



this is from my .emacs.el
---------------------------------------------------------------
;; browser url with mozilla
(when window-system
  (setq browse-url-browser-function 'browse-url-mozilla)
  (setq browse-url-mozilla-program "runmoz")
  (defun browse-url-mozilla (url &optional new-window)
    ;; new-window ignored
    "Open URL in a new tab in Mozilla."
    (interactive (browse-url-interactive-arg "URL: "))
    (message "Starting Mozilla...")
    (shell-command (concat browse-url-mozilla-program " " url))
    (message "Starting Mozilla...done"))
  )
---------------------------------------------------------------

runmoz
----------------------------------------------------------------
#!/bin/sh
#run new url in
LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
# my mozilla need some lib to be loaded

MOZ_PATH=/usr/local/tools/mozilla-1.7/bin

if [ $# = 0 ]; then

    $MOZ_PATH/mozilla -remote 'ping()' &> /dev/null
    if ! [ $? = 0 ]; then
        $MOZ_PATH/mozilla & > /dev/null &
    fi

else
    $MOZ_PATH/mozilla -remote "openURL($1,new-tab)" &> /dev/null
    if ! [ $? = 0 ]; then
        $MOZ_PATH/mozilla "$1" & > /dev/null &
    fi
fi
