How to (automatically) remove or prevent popping up *Async Shell Command* in emacs?

Question

As is asked in here. I could run vi or mate within emacs.

The problem is that after running (async-shell-command "vi"), I always have the *Async Shell Command" popped up as a window.

Can I prevent popping up this windows? Or, can I modify the emacs code to remove the window as soon as it pops up?

(defun runvi ()
  (interactive)
  (let (filename (file-truename buffer-file-name))
    (setq cmd (format "/Users/smcho/bin/mvim %s" (file-truename buffer-file-name)))
    (async-shell-command cmd)))

Answer 1

This will work (assuming cmd is bound to the command you want, like you have above):

(save-window-excursion
   (async-shell-command cmd))
