Currently I'm using shell command - which makes a buffer, showing the output, sometimes locking emacs.

What is a good way to run a process that:

  • Doesn't make a buffer.
  • Doesn't lock emacs.
  • Ignores the stdout/stderr.
  • 2
    start-process with nil for the buffer argument: gnu.org/software/emacs/manual/html_node/elisp/… – lawlist Jul 27 '17 at 15:49
  • async-shell-command might be interesting as well. It should be trivial to write another interactive wrapper that doesn't create a buffer with output. – user12563 Jul 27 '17 at 16:27

call-process, despite normally being used for synchronous process calls:

call-process is a built-in function in `C source code'.

(call-process PROGRAM &optional INFILE DESTINATION DISPLAY &rest ARGS)

[...]
Insert output in DESTINATION before point[...]0 means discard and don't wait
[...]
If DESTINATION is 0, `call-process' returns immediately with value nil.

  • call-process requires commands to be split up. I ended up using: (call-process-shell-command my_command nil 0))))) – ideasman42 Aug 1 '17 at 5:02
