Can't get Cron job to run

I'm attempting to get this simple Cron command to run from the Cron jobs panel.
** * * * * find /home/CPANELUSERNAME/public_html -mtime -1 \! -type d -ls

The purpose of the command is to alert me when a file changes. CPANELUSERNAME has been changed to my user name and I have set an email address in "send an email when a job runs".

To test this I alter a simple text file in the public_html folder. I don't receive a message indicating the change. I contacted my hosting service Godaddy. They tested Cron functionality on the server. Initially it didn't work. After some adjustments they were able to verify that it is working on the server. However I can't get this to work from inside the control panel.

Any help would be greatly appreciated.

 

Thanks for your reply. The extra ** was a typo in my post. It reads
* * * * * find /home/CPANELUSERNAME/public_html -mtime -1 \! -type d -ls
In the Job.

I have limited knowledge and am not familiar with shell scripts. Is this something I can do in cpanel?

I don't have SSH Access. It looks like it will take a day or so to activate it. Godaddy won't touch code for me.

 

I suspect that Cron is not working for me on godaddy. Can anyone recommend a simple command I can use to test it from within cPanel?

 

Thanks I'll give that a try.
