Setting cron only from morning to evening

Question

I need to run a daily cron.

Cron’s working hours should be 11:00 in the morning until 7:00 in the evening.

At this time, cron should start every 15 minutes daily.

Does the same thing after a night in cron should work every hour?

Is this possible using the linux cron scheduling type.

Or I need to manage this from any scripting language.

Answer 1

*/15 11-18 * * * statement/to/run 0 0-10,19-23 * * * statement/to/run 

Must do what you need.

* / 15 or 0,15,30,45 will do the same and work every 15 minutes.

You need to split it into two entries, since you want it to work differently at different times of the day.

Answer 2

I don’t think you can do this with one rule, so you will need to use three, for example:

 0 00-10 * * * /path/to/cron/job 0,15,30,45 11-18 * * * /path/to/cron/job 0 19-23 * * * /path/to/cron/job 

The first rule is processed from 00:00 to 10:00, the second from 11:00 to 18:45 and from 19:00 to 23:00 to complete the set.

Obviously, you can adjust the offsets within an hour, when everything will be done by changing the values ​​in the first column.
