To run a program, script or job every hour, select '0' in the minute box, our default, and leave the rest blank. To run a job every night at 9:30, you would select '30' in the minute box, '21' in the hour box and leave the rest set to the asterisk defaults. (You can find more on commands here.) Once you have established the time, enter the full path to your program, script or job in the 'Execute This Path And Script' box. Click on Calculate and the resulting job command line will be displayed for you. You may cut and paste it if you like.
