    Adding a new task

    • Click "New Task..." The Add of modify existing task dialog will be displayed.
    • 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).
