Systemd/timers: Difference between revisions
added alternative example of the call for the binary and command, the quotes confused me when replicating this for rclone (maybe more me but didn't seem like it hurt to add) |

====Using the <code>systemd.services.<name>.startAt</code> shorthand==== | |||
If you only want a service to execute at an interval and don't plan to configure the timer much more, you can use the <code>systemd.services.<name>.startAt</code> option. This will have the underlying systemd module in nixpkgs create the timer for you, and set its <code>OnCalendar</code> field. Note that the semantics for <code>OnCalendar</code> are different to <code>OnUnitActiveSec</code>. | |||
This example shows the previous <code>hello-world</code> service configured with <code>startAt</code>, running every 5 minutes. | |||
