Evaluate these, then evaluate the commented-out
in-Emacs test or run the shell command. (If you
are a bash user syntax may vary slightly.)

(defun signal-usr1-f ()
  (interactive)
  (message "Got signal: USR1") )

(define-key special-event-map [sigusr1] #'signal-usr1-f)

;; test:
;;
;;  from emacs:  (signal-process (emacs-pid) 'sigusr1)
;;
;;   from zsh:   kill -s usr1 $(ps -e | grep emacs | cut -d " " -f 2)
