make the script (besdies that scripts don't belong to /etc) a oneshot-service and learn about https://www.freedesktop.org/software/systemd/man/systemd.target.html the probably easier option would be ExecStartPost/ExecStopPost in a dropin in /etc/systemd/system/apache2.service.d/whatever.conf https://coreos.com/os/docs/latest/using-systemd-drop-in-units.html no need for books, these are basic tasks _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
