What is a Cron Job & Crontab?
In computing, a cron job is a time-based task that is set to run at certain predetermined times or intervals. A cron job can be used to schedule anything from basic tasks like running backups to more complex tasks like sending out email alerts or syncing files between servers. Cron jobs are typically used for maintenance or administrative tasks that need to be performed on a regular basis.
A crontab is a table or list of commands that are scheduled to run at specified times. The commands in a crontab file (also called a “cron table”) are normally executed by the cron daemon, which runs in the background and executes these commands automatically.
Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every minute between 12:00 pm and 11:00 pm“:
FUN FACT: If you need to delete a cron job, simply remove the corresponding line from the crontab file and save your changes..
