Scheduler (cron)


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.

To open the scheduler, log in with a user account and enter Main Scheduler.
