This lists numerical signal values: $ systemctl --signal list SIGNAL NAME 1 SIGHUP 2 SIGINT 3 SIGQUIT ... 62 SIGRTMIN+28 63 SIGRTMIN+29 64 SIGRTMIN+30 This is useful when trying to kill e.g. systemd with a specific signal number using kill. kill doesn't accept our fancy signal names like RTMIN+4, so one would have to calculate that value somehow. Doing systemctl --signal list | grep -F RTMIN+4 is a nice way of doing that.
