(I am noob in guile atm) If you want to dig into it, the GNU manual is not half bad: https://www.gnu.org/software/libc/manual/html_node/Processes.html Guile just wraps those same C functions, so that description applies quite well to Guile. Here’s the Guile reference for the procedures you’d need: https://www.gnu.org/software/guile/manual/html_node/Processes.html Alternatively, if you are feeling adventurous – you must be if you are using Potato Make :) – you could try and use Gash, too. You would end up with a very Scheme-y Make experience indeed! Gash’s interface is laser focused on shell semantics so far, so it’s a little wonky as a Scheme library, but here’s an example: (use-modules (gash environment) (gash shell)) (sh:async (lambda () (execlp "emacs"))) (display "waiting a bit...\n") (sleep 5) (let ((emacs-pid (get-last-job))) (display "sending SIGTERM to ") (display emacs-pid) (newline) (kill emacs-pid SIGTERM)) Gash is very much experimental software when used like this, though. The latest release does not have ‘sh:async’, so you would have to build it from Git. It might not be super practical, but it would be fun! :) -- Tim
