• You need to add your custom console command to OS crontab.

  crontab -u <Magento file system owner username> -e

  For example,

  crontab -u magento_user -e

• Then add your commands with time interval in the end of the file as save,

  * * * * * <path to php binary> <magento install dir>/bin/magento your_command:your_sub_command

  For example,

  * * * * * php /var/www/html/mysite/bin/magento myproduct:updateprice

  Here, * * * * * is the time interval for every minute.

  • CRON_1MINUTE = '* * * * *';
  • CRON_5MINUTES = '*/5 * * * *';
  • CRON_10MINUTES = '*/10 * * * *';
  • CRON_15MINUTES = '*/15 * * * *';
  • CRON_20MINUTES = '*/20 * * * *';
  • CRON_HALFHOURLY = '*/30 * * * *';
  • CRON_HOURLY = '0 * * * *';
  • CRON_2HOURLY = '0 */2 * * *';
  • CRON_DAILY = '0 0 * * *';
  • CRON_TWICEDAILY = '0 0,12 * * *';
