• Enter the command to be run. Click the folder icon to choose it from a dialog.
• Enter a comment (optional). This should be descriptive, explaining what the task will do as the command may not always be obvious.
• Click Enable this task to enable the task to run.
• Click Run at system bootup to enable the script to run each time the system is booted.
• Click Run every day to enable the script to run every day. This will automatically select the appropriate options.
• Using the buttons, choose when the command should be run. Not all parameters are required, those not needed may be left blank.
  • Hours and Minutes are the time of day to run the task, not an interval.
• When done, click OK. The task till be added, and scheduled if enabled.

Hints

• All the files that are modified are located in the /etc/cron directory where there are numerous files to look at.

• The command-line tool that allows you to have a look at the currently installed cron-jobs is

  crontab -l

  (that's the letter L).
