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

Hi Andreas,

Thanks a lot for helping.

The purpose is simply for opening them (asynchronously), viewing the pdf
(continuing to work in Emacs), (maybe add annotations to the pdf and save
it).

I use 'dired-mode' as 'file manager' and often would like to open and view
pdfs in Okular. I also have other 'dired-guess-shell-alist-user' settings
like opening pngs in eog or mp3s in VLC. But everytime I open a file, I get
this annoying *Async Shell Command* buffer (either empty or with debug
output) and I have to manually close it via C-x 0 etc. to get rid of it. I
know that it might contain useful information sometimes and I wouldn't be
against it appearing hidden (in the buffer list). But being distracted by
this buffer in dired-mode is really unpleasant. If I only knew more emacs
lisp...

Cheers,

Marius
