Creating a Cron Job to Run Every 6 Hours

Creating a cron job to run every 6 hours is simple. Just add the following line to your crontab file: ``` 0 */6 * * * /path/to/command ``` This cron string tells the cron daemon to run the specified command every 6 hours, on the hour.

Cron Syntax

The cron syntax is a simple way to specify when a cron job should run. The syntax is as follows: ``` minute hour day month weekday command ``` Each field in the cron string can be a number, a range of numbers, or an asterisk (*). The asterisk means "every." For example, the following cron string would run the specified command every minute: ``` * * * * * /path/to/command ``` The following cron string would run the specified command every day at 3 AM: ``` 0 3 * * * /path/to/command ```
