How do I schedule a cron job every minute?

How does it work? The asterisk (*) operator specifies all possible values for a field. For example, an asterisk in the hour time field would be equivalent to every hour or an asterisk in the month field would be equivalent to every month. An asterisk in the every field means run given command/script every minute.

How do I run a cron job every 20 minutes?

For example, if you have 1-10/2 in the Minutes field, it means the action will be performed every two minutes in range 1-10, same as specifying 1,3,5,7,9 . Instead of a range of values, you can also use the asterisk operator. To specify a job to be run every 20 minutes, you can use “*/20”.

Do cron jobs run automatically?

Cron wakes up every minute to examine all stored crontabs and see if any command needs to be executed in the current minute. Additionally, Cron monitors the modification time of each crontab file on the system. If any crontab has been changed, it is automatically reloaded into memory.
