What is a Cron Job & Crontab?

A cron job is a task that is scheduled to run at a specific time or interval. Cron jobs are typically used for maintenance or administrative tasks, such as backing up data or updating software.

Crontab files are typically stored in the /etc/crontab file, but they can also be stored in individual user’s home directories. To edit your own crontab file, you can use the command “crontab -e”. This will open up the file in your default text editor.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every hour between 4:00 am and 10:00 am“:

  • Field 1: (0) indicates that the task will be run at minute 0.
  • Field 2: (4-10) indicates that the task will be run between hours 4 and 10 (4 am to 10 am).
  • Field 3: (*) indicates that the task will be run every day of the month.
  • Field 4: (*) indicates that the task will be run every month.
  • Field 5: (*) indicates that the task will be run every day of the week.
