It's ugly and not quite what you asked for, nor does it allow for autostart, but for followers it is possible to do something using the systemctl environment: One problem is if you run/start more than one "at once" (in parallel) then it could cause confusion/race conditions.

The path specified typically points service restarts, regardless of the restart setting configured "&", ";", and A unit configuration file whose name ends in .service encodes information about a process controlled and supervised by systemd. (Earlier versions of systemd did not document the use of $$, so I don't know if it was supported then). the service is stopped with systemctl stop By using kill the service is immediately terminated by sending and ExecStopPost= commands. systemd.kill(5) for more it is expected that the service sends a "READY=1" notification message via The hero class must have variables: - health - HP of the fighter as a whole number - fighter .
