Cron jobs are scheduled tasks, that run on regular intervals of time pre-set by the user and they execute scripts developed in several programming languages - PHP, Perl, Bash, and the like. In accordance with what exactly a cron should do, it can run every minute, weekly or perhaps annually. There're many useful applications to make use of cron jobs in your everyday management of a site. For example, a backup of the whole site can be generated once per day or maybe weekly or an e-mail with all fresh signups for the day can be sent to a particular email address. Such automatic options can make the administration of every website faster and easier. There aren't any particular file types that can be allowed or forbidden, so every script can be run employing a cron job.
