How To Verify If A Cronjob Exists On A Server

Ehsan Dowlatshah
  • Updated

The Whole Server: 

 

You can run this command, which will list all the existing cronjobs for all the users, including root, on the server: 

 

for user in `whmapi1 list_users | egrep -i ".*-\ .*" | awk '{print $2}'`;do printf "Username >>>>>> %s \n" $user && crontab -l -u $user;done

 

The output looks like this: 

Username >>>>>> cptest
no crontab for cptest


Username >>>>>> root
@reboot /usr/local/cpanel/bin/onboot_handler

For A Specific User: 

 

If you already know the user and you only want to see the list of cronjobs associated with that specific account/user then you can use this command: (Replace $USERNAME with the username of the account)

 

cpapi2 --user=$USERNAME Cron listcron
