Question

ubuntu

Hello.
The task is to run a python script on a schedule - every 15 minutes from 8:00 to 20:00.
Did it like this:

*/15 8-20 * * * /usr/bin/python3 /home/donik/python/sweeper.py >> /home/donik/python/sweeper_cron.log 2>&1

Timezone is correct, but the script continues to work after 20:00
Tell me how to fix it.

Answer 1

*/15 8-19 * * *...

Answer 2

Much more flexible can be configured through systemd timers . Move on already, damn it, into the 21st century ...
