Command to ON/OFF cron job
Solution 1:
For the single cron job you can comment by editing with crontab -e.
If you have to stop all the cron jobs:
sudo service crond stop
sudo service crond status
sudo service crond restart
or
/etc/init.d/cron start
/etc/init.d/cron status
/etc/init.d/cron restart
or
sudo systemctl stop cron
sudo systemctl status cron
sudo systemctl restart cron
