What is a Cron Job & Crontab?

A cron job is a time-based task that is set to run at specific intervals. These jobs are usually used for maintenance or automation purposes. For example, a cron job could be set to delete temporary files every week so that they don’t take up space on the server.

Each user has their own crontab file, and the commands in this file are only executed by that particular user. The file contains instructions for the cron daemon. To edit your crontab file, you can use the crontab command.

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 1:00 pm and 11:00 pm“:

  • Field 1: (0) indicates that the task will be run at minute 0.
  • Field 2: (13-23) indicates that the task will be run between hours 13 and 23 (1 pm to 11 pm).
  • 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.
