Question

I have used cron to run PHP:

* * * * * /var/www/html/new12345/testing.sh

This bash contains:

#!/usr/bin/php -q   /var/www/html/new12345/shell_call.php

and my shell_call.php has a variable:

$a= shell_exec("./main.sh $l");

My main.sh is suppose to return a particular filename which it returns when executed in terminal.

However, when I try to run main.sh from this procedure, I find value of a to be null.

Answer 1

I’d look at the working directory for the php scripts as the first suspect. try:

$a= shell_exec(dirname(__FILE__). "/main.sh $l");
