sudo crontab -u www-data -e

# Append the line in the configuration. This should run the command every 5 minutes. (Recommended by Nextcloud)
*/5 * * * * php -f /var/www/nextcloud/cron.php

# To make it run the command every day at 13:00 Hrs.
0 13 * * * php -f /var/www/nextcloud/cron.php

# You can verify if the cron job has been added and scheduled by executing:
sudo crontab -u www-data -l

sudo -u www-data php /var/www/nextcloud/occ memories:index
