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
$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
