systemd-timers

Better systemctl list-timers

VS. systemctl list-timers

systemd has systemctl list-timers command to list installed systemd timers.

core@ip-10-1-2-255 ~ $ sudo systemctl list-timers

We cannot check task execution result (whether last execution succeeded or failed) at this view. We have to do systemctl status <unit> for each task. It's so bothersome (at least for me).

This systemd-timers show task execution result at once. They are colorized; success is green, failed is red.

core@ip-10-1-2-255 ~ $ systemd-timers
UNIT                      LAST                                          RESULT   EXECUTION TIME          NEXT                           SCHEDULE
