I know that there are a lot of places where you can find instructions on how to set up your Cron jobs on Cpanel. Sometimes you just want a simple solution which you can Copy & Paste and this solution should work so you not waste any more time on this matter.
Here's what I use everytime I need to set up a Cron job on Cpanel, especially on Drupal sites:
wget -qO- [URL-TO-YOUR-SCRIPT-THAT-NEEDS-TO-BE-EXECUTED] &> /dev/null
It worked on every shared host I tried it and it doesn't save any files with the output of the script nor it needs any other software installed on the server.
