Trim on my SSD Hardisk

[Snubbi]

I have used this commands.
sudo systemctl enable fstrim.timer
sudo systemctl start fstrim.timer

And got this output

[carl@andersen ~]$ sudo systemctl start fstrim.timer
[sudo] adgangskode for carl:

Will it then start every Sunday at 07 14:59:50
or Mon 2021-03-08 00:55:14 CET???

systemctl list-timers

This will inform you of the state for the currently activated timers - including when they where last run and the count down until next run.

Clarifying:

@Snubbi

I’m not interested in getting up at nigh

Timers which missed their timed property will be run at next available time slot - it they missed at time-slot they will be run at next system activation

I’m not interested in getting up at night , so how can I change the time to 12:00 in the middle of the day

Don’t worry, the SSD will be trimmed the next morning.

Such timer has the Persistent=true option, so will be executed when you reboot or relogin (eg on resume after suspension) in your session.
