Cómo verificar que Cron esté funcionando o no
$ systemctl status cron # checks if cron is running
$ sudo systemctl enable cron.service # enable cron to run on boot
$ sudo systemctl start cron.service # start cron now
$ sudo crontab -l # show all currently running cron jobs
$ sudo crontab -u panda -l # show all cron jobs running for user panda
