Hello, In order to restart updated daemons on filesystems, I created a script[1] which lists all PID by service and look for updated files in /proc/$pid/maps.
To get all PIDs of a service, I use "systemctl show -p ControlGroup" to craft a path to the "tasks" file. But something wrong happen with escaping with some units (e.g serial -getty) This works: #cat /sys/fs/cgroup/systemd/$(systemctl show systemd-logind.service -p ControlGroup|cut -f2 -d=)/tasks 286 This not: #cat /sys/fs/cgroup/systemd/$(systemctl show serial-getty@ttyS0.service -p ControlGroup|cut -f2 -d=)/tasks /sys/fs/cgroup/systemd/$(systemctl show -p ControlGroup|cut -f2 -d=) cat: /sys/fs/cgroup/systemd//system.slice/system-serial\ x5cx2dgetty.slice/serial-getty@ttyS0.service/tasks: No such file or directory What's the right way to get all pid belonging to a service? How can I unescape strings from systemctl? This is happening since a long time. I made these tests on systemd v220 et v219.
