如何为bash脚本指定运行时间？

Question

I was looking for a way to continuously run a PHP script every 15 seconds online, so that I may manage some accounts using an API. I was able to find a script that satisfies what I was looking for as follows:

#!/bin/bash
#This script runs every 15 seconds
#This script is ran in /etc/rc.local (startup)

while (sleep 15 && php test.php) &
do
    wait $!
done 

This script works perfectly and runs every 15 seconds. However, now I want to modify the script such that it may

1. do what the script is already doing
2. run a second script, every 5 minutes

Is there a way to modify the current while loop so that I may achieve this? Thanks!

Answer 1

There are much better ways to do this because PHP requires and HTTP request to run that file.

1. Run a cron job to run this request every set interval (not recommended)
2. Use another program like python which can run a daemon to do this
3. Do the calculation every time the page is requested (recommended and almost always possible)
