systemd service

On Linux operating systems, you may want to run TBBM PROZESSING using systemd timers.

1. Install Python 3.14
2. Add a service user prozessing
3. Create /var/prozessing and make it writable for the user prozessing
4. prozessing.pyz to /opt/PROZESSING/prozessing.pyz
5. Install INI files to /opt/PROZESSING/ini/
6. Install systemd service PROZESSING@.service (see below)
7. For each INI file foobar.ini, create a PROZESSING@foobar.timer (see below) in /etc/systemd/system/
8. For each INI file foobar.ini, run systemctl enable --now PROZESSING@foobar.timer

Helpful commands for the service and timers:

• systemctl status PROZESSING@foobar.service – get status of the service
• systemctl status PROZESSING@foobar.timer – get status of the timer
• systemctl start --no-block PROZESSING@foobar.service – run service now
• systemctl enable --now PROZESSING@foobar.service – enable and start the timer now
• systemctl list-timers – list all timers

Systemd timers support a variety of timespans and calendar Events, see systemd.time for details.
