Systemd timer to restart systemd services on a schedule

README.md

First copy the files

Place the .timer and .service file in the /etc/systemd/system/ folder.

How to use

To use, let's assume I want to restart nginx every night. Then I'd do:

systemctl enable --now restart_nightly@nginx.timer

And that's it!

To verify you can type

systemctl list-timers

And it should report something like this:

NEXT                          LEFT                LAST                         PASSED             UNIT                         ACTIVATES
