General Information

Preferences-system.png KCron is a tool for running applications in the background at regular intervals. It's a graphical interface to the Cron command.

KCron is a standard application that is prepackaged for KDE workspaces.

The Task Scheduler in Plasma 5

Usage

Task Scheduler can be started by starting the System Settings application, and selecting Startup and Shutdown -> Task Scheduler. New tasks can be added and existing tasks edited or removed.

Adding and Modifying tasks

  • Click "New Task..." to add a new task, or "Modify" to modify an existing task. The Add or modify existing task page will be displayed.
The "Add or modify task" page of SystemSettings
  • 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 will 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).
