cron job to run each minutes from monday to friday from 9:15AM to 3:30PM

Question

I have to run two cron jobs for the following scenarios.

1. job1.php Should run once in a day at 9:12 AM on Monday to Friday. (five days in a week)
2. job2.php Should run in each minutes from 9:15 AM to 3:30 PM on Monday to Friday. (five days in a week)

I have another 4 cron jobs which needs to be implemented in my project. But all that can be derived from the above two scenarios.

Answer 1

First one is easy.

12 9 * * 1-5 <full_path>/job1.php

Second one is tricky. I split that into 3 entries.

15-59 9 * * 1-5 <full_path>/job2.php

* 10-14 * * 1-5 <full_path>/job2.php

0-30 15 * * 1-5 <full_path>/job2.php

Cron Syntax

*    *    *    *    *  command to be executed
