    Informazioni generali

    KCron è uno strumento per eseguire automaticamente applicazioni ad intervalli regolari. È un'interfaccia grafica per il comando Cron.

    KCron è un'applicazione standard negli ambienti KDE.

    Task Scheduler is a graphical front end to the standard "cron" utility. With it, commands (or "tasks") can be run at specific times, on a certain day or date, or at specific intervals (time between execution).

    Utilizzo

    In KDE 4.4 KCron è un modulo accessibile in Impostazioni di sistema -> Avanzate -> sezione Sistema -> Pianificatore di operazioni. Se non è presente controlla di aver installato il pacchetto kdeadmin. In KDE 4.5 lo troverai in Impostazioni di sistema -> sezione Amministrazione del sistema -> Pianificatore di operazioni. Alcune distro creano un pacchetto separato per KCron, dunque se non lo vedi dovresti cercare questo termine nel tuo repository.

    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.

    Suggerimenti

    • Tutti i file che vengono modificati si trovano nella cartella /etc/cron dove ci sono numerosi file da guardare.
    • Lo strumento a riga di comando che ti permette di vedere i cron-jobs attualmente definiti è
      crontab -l
      (l'ultima è la lettera L).
