I am developing a Yii application which has a cron-job running along with. Everything is OK, cron job run successfully. But on Ubuntu when I tried to list all crontabs created by my account (the account used to login to server) as well as www-data (the one represent for Apache), I cannot find anything useful. They all told me that no crontab for that_user. How can I find the list of those crontabs and kill them? Thank you.
If you using VDS then you can run this commands:
crontab -l - show list of all cronjobs for current user
crontab -e - edit list cronjobs for current user
If you have only FTP access, then crontab setup located in DirectAdmin panel (or other server control panel)
In Ubuntu connect your sever with terminal and run command crontab -e using it you will see and edit or delete all your cron-job.
