can not run linux external program with php through browser

[amkh]

Hello, I have php page like this:

<?php

if (isset($_POST['logFilePath']))
{
$logFilePath = $_POST['logFilePath'];

}
else
logFilePath ="";

$command = "wireshark " . $logFilePath ;
shell_exec($command);

?>
wireshark is a linux application that analyze traffic or tcpdump format files

I test echo shell_exec('ls');
and it works but my command not.


I copy wireshark at the current directory of my php page and change it chmod to 777 to give access of running it to apache but it doesn't work yet.

when I run it as command line it works correctly and wireshark opens but when I run it through browser it doesn't work. What it the problem and how can i solve that.

instead of just using the command as wireshark include the full path to the executable, my guess is its in a location that isn't on the apache user's path
