I runned cron command, now all cron group are running. But I wanted to stop my custom group cron. Please tell me how to stop it?
Follow below step it's working for me You can by running cron remove command:
php bin/magento cron:remove ----group index
It will only remove cron tasks from crontab but not the exact cron codes/files.
If you wish to run the cron jobs again, you just need to run cron run command twice: php bin/magento cron:run
The first time run is to discover cron tasks to run and the second time — to run the tasks themselves. The second cron run must occur on or after the scheduled_at time for every task.
