Cron Jobs
Cron jobs are timetabled tasks, that run on regular time intervals set by the end user and they also execute scripts developed in different programming languages - PHP, Perl, Bash, and so on. Depending on what exactly a cron has to do, it can run each minute, weekly or maybe each year. There're numerous useful applications to make use of cron jobs in the day-to-day administration of a website. Such as, a backup copy of the entire site may be generated every day or perhaps once a week or an e-mail message with all fresh signups for the day can be delivered to a certain e-mail. Such automatic options will make the administration of any website faster and easier. There won't be any particular file types that are allowed / forbidden, so every script can be run by using a cron job.
