cron - Cronjob every x hours between 23-16 not working -

-

partly using stackoverflow search figured out how run cronjob every 3 hours not between 23h-16h. means pause between 16h today untill 23h today. cronjob should start running every 3 hours @ 23h , stop @ 16h, start again @ 23h.

this result:

0 23-16/3 * * * /usr/local/bin/flexget -c /media/usb/downloads/flexget/config.yml --cron

now question: why not working? not run @ :(

i tried:

* 23-16/3 * * * /usr/local/bin/flexget -c /media/usb/downloads/flexget/config.yml --cron

(not sure difference 0 or * minutes, rounded hours or not?)

this work:

0 */3 * * * /usr/local/bin/flexget -c /media/usb/downloads/flexget/config.yml --cron

but runs every 3 hours every day, without pause between 16-23.

you can list hours explicitly.

0 2,5,8,11,14,23 * * * /usr/local/bin/flexget -c /media/usb/downloads/flexget/config.yml --cron

note not same replacing 0 minutes *, like:

* 2,5,8,11,14,23 * * * /usr/local/bin/flexget -c /media/usb/downloads/flexget/config.yml --cron

the latter starts on every minute on hours specified, i.e. 2:00, 2:01, 2:02, ..., 2:59, 5:00, 5:01, ... 5:59, ...
