I want to run a shell script within a php webpage to check some processes running on my system (Ubuntu 12.04). Googleing I've found about shell_exec() but I can't manage to run the script when loading php.

This is the php code I use.

$output = shell_exec('./dirlist.bash');
echo "<pre>$output</pre>";

and the piece of html I get

<pre></pre>

Also tried $output = shell_exec('sudo -u www-data ./dirlist.bash');

dirlist.bash does ls -l (just for testing script and shell_exec)

I think it is not a permission problem. Running directory grants write and execute privileges for all users (I should be careful here).

drwxrwxrwx  4 meteo meteo 4096 mar 11 15:20 RAMS

User www-data has been added to sudoers file in case it was needed

www-data ALL = (meteo) NOPASSWD: /home/meteo/www/RAMS/dirlist.bash

Thanks in advance

what's your interest
