systemctl

Shutdown system systemctl shutdown. Reboot with systemctl reboot.

Own service

Used systemctl in powercontrol-server to create my own service.

journalctl

# Just use the journalctl command, as in:

journalctl -u service-name.service

# Or, to see only log messages for the current boot:

journalctl -u service-name.service -b

# For things named <something>.service, you can actually just use <something>, as in:

journalctl -u service-name
