There is a simple way to call a simple bash script inside php script page:

- Below is a simple bash script called script.sh

#!/bin/bash
echo “Successful call test script“
exit 0

You will need to set chmod 700 to  be root executable. Then  save the script to your apache root folder.

There is a simple php script called testing.php

$script = “/var/www/script.sh”;
$ver1 = system($script, $retval);
if ($retval == 0 ) {
echo “Returned 0″;
}
else {
echo “Returned not zero”;
}
die;

?>

Save this to same root location where your script.sh is.

If you browse the page testing.php, it would have a return value spitted out by script.sh bash script.

You can call this script from here : http://www.debian-tutorials.com/testing.php

Enjoy.
