Usage

First define what variables your application needs and their values, then select your application. When this is done you select at which times your application should be run and you're all set.

In KDE 4.4 KCron is a module which could be found in System Settings -> Advanced -> System section -> Task Scheduler. If it is not present, please check that you have the kdeadmin package installed. In KDE 4.5 as well as in later versions you will find it in System Settings -> System Administration section -> Task Scheduler. Some distros make KCron a separate package, so if it's not visible you should query your repository for it.

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).
