Task Scheduler in Plasma 5

Uso

En En 4.4 KCron es un módulo que puede ser encontrado en Preferencias del sistema -> Avanzado -> sección Sistema -> Planificador de tareas. Si no aparece, por favor comprueba si tienes instalado el paquete kdeadmin. En KDE 4.5 lo encontrarás en Preferencias del sistema -> sección Administración del sistema -> Planificador de tareas. Algunas distribuciones tienen a KCron en un paquete separado, por lo que si no es visible deberías buscarlo en tus repositorios.

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.

Tip

Click Run Now to run a task immediately after adding or modifying the task.


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.

  • The value the variable will contain. This can be a number or string.
  • Enter a brief description of the variable.

Sugerencias

  • Todos los archivos que se modifican se encuentran en el directorio /etc/cron donde hay muchos archivos que mirar.
  • La herramienta en línea de comandos que te permite echar un vistazo a los trabajos instalados en cron es
    crontab -l
    (es una letra L).
