What is a Cron Job & Crontab?
A cron job is a time-based task that is set to run at specific intervals. This can be anything from running a script every hour to backing up a database every day. Cron jobs are typically used for maintenance or automation purposes.
Crontab is a file that contains commands and instructions for the cron daemon to execute. The crontab file is usually located in the /etc/cron directory. Each user on a system can have their own crontab file. The commands in the crontab files are executed by the cron daemon at the specified times.
Cron Fields
Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every day/night at midnight“:
- Field 1: (0) indicates that the task will be run at minute 0.
- Field 2: (0) indicates that the task will be run at hour 0 (12 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.
