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.

A crontab is a file that contains a list of commands that are to be executed at specified times. The commands in the crontab are executed by the cron daemon, which runs in the background.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every 22 minutes“:

Field 1: (*/22) indicates that the task will be run every 22 minutes.

Field 2: (*) indicates that the task will be run every hour.

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.

 

FUN FACT: When editing your crontab, it is important to use a text editor that supports Unix-style line endings (LF), as opposed to Windows-style line endings (CRLF)..
