I have C-x C-k bound to kill-this-buffer. But when I enter into a buffer which is running a process like Python or MySQL, if I do C-x C-k it asks

Buffer "*Python*" has a running process; kill it (y or n)?

How can I kill process buffers without confirmation?

Remove the corresponding function from the relevant variable :

(setq kill-buffer-query-functions (delq 'process-kill-buffer-query-function kill-buffer-query-functions))

How did I find this ?

kill-this-buffer uses kill-buffer internally, which references the variable kill-buffer-query-functions.

  • I put this line into my startup file and no errors are shown in the message buffer. When I have a scheme process running (started with run-scheme) when exiting still a dialog pops up and asks "Active processes exist; kill them and exit anyway?". – user905686 Aug 24 '16 at 10:32
  • @user905686 That's a question asked by save-buffers-kill-emacs and unrelated to killing the buffers. – YoungFrog Aug 24 '16 at 11:48
  • Now I see that it works for just killing a buffer. I thought exiting emacs would try to kill the buffers and that therefore the confirmation dialog has the same origin. I asked a new question: Exiting emacs without confirmation to kill running processes. – user905686 Aug 25 '16 at 9:43

Or the simpler one would be :

(setq kill-buffer-query-functions nil)

Inspired from abo-abo config
