Cron jobs are typically used for maintenance or administrative tasks that need to be performed on a regular basis.

A crontab is a file that contains instructions for the cron daemon. The cron daemon is a program that runs in the background and executes tasks at specified times. A crontab file consists of a series of lines, each of which represents a task to be executed. Each line has five fields, separated by spaces or tabs.
