Re: How to suppress/avoid *Async Shell Command* buffer?

[Hongxu Chen]

There is a tool called `openwith' that might meet your needs; you might
see this page for details:
http://www.emacswiki.org/emacs/OpenWith
It is available in elpa but I recommend that you customize the external
apps yourself.

Also Lee Xah has written a snippet for this issue, and you can just map
some key.

Hope these would be helpful.
