Sheduler (cron) (ISPmanager)

ISPmanager allows automatic execution of scheduled jobs using Cron. Cron is a daemon that executes commands at specified intervals. Cron jobs are scheduled tasks (commands) that are executed by such daemon at predefined times. A cron job is a series of simple tasks run from a script.

This module can be used to manage your cron jobs: you may add, edit, delete, run cron jobs, and configure the global parameters, such as e-mail address and paths. The module is available only for the root users.
