What is a Cron Job & Crontab?

A cron job is a time-based task that is set to run at a specific time or interval. This can be used to automate tasks such as running backups, sending emails, or running system maintenance scripts.

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 5 days at 6:30 pm“:

  • Field 1: (30) indicates that the task will be run at minute 30.
  • Field 2: (18) indicates that the task will be run at hour 18 (6 pm).
  • Field 3: (*/5) indicates that the task will be run every 5 days.
  • 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.
