Description

Crontab is a tool used to schedule tasks to run on a regular basis. It is a time-based job scheduler used by Unix-like operating systems to execute commands at a given time. It is typically used to automate system maintenance or repetitive tasks. Crontab consists of a series of tasks, referred to as cron jobs, that are defined by a crontab file. This file contains a list of commands that are to be executed at specific times or dates. A user can set up cron jobs to run daily, weekly, or monthly, or at other intervals. Each cron job is specified using a single line entry in the crontab file. This line consists of six fields, separated by spaces or tabs. The fields specify when the command should be run, what command to run, and which user the command should run as. Crontab is a great tool for automating tasks and can be used to perform system maintenance, send email notifications, run backups, and more.
