为什么我的柜台不工作？

Question

I have a bash script that is intended to run a PHP script every 15 seconds, and a second PHP script every 5 minutes. However, my counter to do so is not working. I can't find where the bug is.

#!/bin/bash

while (true)
do
    sleep 1
    if (( count % 15 == 0 )) ;then
            php test.php
    fi
    if (( count % 300 == 0 )); then
            php test2.php
            count=0
    fi

     (( count = count +1 ))


done

When I run this script, it gives me this error in the console:

script.sh: 8: script.sh: count: not found
script.sh: 11: script.sh: count: not found
script.sh: 16: script.sh: count: not found
script.sh: 8: script.sh: count: not found
script.sh: 11: script.sh: count: not found
script.sh: 16: script.sh: count: not found

I have tried to instantiate the counter prior to the loop, but it ends with the same result. Any help would be greatly appreciated!

You probably execute the script with sh instead of bash. Make sure you execute it directy with ./script.sh (so that the shebang binary is used) or call it explicitly with bash bash script.sh
