Generel information
Opgaveskemalæggeren en brugerflade til det almindelige "cron"-program. Med dette kan kommandoer (eller "opgaver") blive kørt på faste tidspunkter, på en given ugedag eller dato eller med et givet interval.
Brug
I 4.4 er KCron et modul, som findes i
. Hvis den ikke findes der, så bør du sikre dig, at du har pakken kdeadmin installeret. I KDE 4.5 og senere versioner finder du den i . I nogle distributioner kommer KCron som en særskilt pakke, så hvis du ikke kan se den, så søg i pakkearkiverne efter den.Adding and Modifying tasks
- Click to add a new task, or "Modify" to modify an existing task. The Add or modify existing task page 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.

Removing a task
To completely remove a task, select the task from the list and click the Delete button. This will permanently remove the task.
Environment Variables
Sometimes a task or multiple tasks need a specific variable set, it must be added in the Environment Variables section. The cron utility uses its own environment, system-wide and user-specific variables are not used. Click New Variable to add a new variable definition, or Modify to change an existing variable.
- Enter the name of the variable to use. This name:
- Must consist of letters, digits, and underscore ('_') only
- Must start with a letter
- Should not be a reserved or commonly used system variable. See https://pubs.opengroup.org/onlinepubs/000095399/basedefs/xbd_chap08.html for more information
- The value the variable will contain. This can be a number or string.
- Enter a brief description of the variable.
Tips
- Alle de filer, som modificeres findes i mappen /etc/cron, hvor der er mange filer, som kan bruges som eksempler.
- Kommandolinje-værktøjet til at se det aktuelt installerede cron-job er
crontab -l
(det er bogstavet L).
