Cron Jobs

For cPanel version 11.30

Cron jobs are scheduled tasks that take place at predefined times or intervals on the server. Often, a cron job is a series of simple tasks executed from a script file. cPanel offers this screen as a tool for setting up cron jobs.

note Note: Be careful when scheduling cron jobs. Setting them to run too often may slow down your server.
