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

You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.
$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);
echo "<pre>$output</pre>";
