Question

I am looking for a way to run a PHP script between two set times (probably 5AM and 10PM), every 90 seconds. I was thinking of just making a bash script to move the file in/out of a directory at different times, but that would be messy and make all sorts of errors. Is there a better way to go about this?

Answer 1

To get a 90 seconds interval you could e.g. create two crontab entries with an interval of 3 minutes and delay one of them by 90 seconds:

-*/3 5-22 * * * your_script.php
-*/3 5-22 * * * sleep 90;your_script.php
