Shell Programming and Scripting

Hi I'm a newb to php scripts. My task requires me to run a shell script from within the php script which I believe I've figured out. What I'm trying to do now is output something to the web page from the called shell script. when I use "echo" from the called shell script I don't get any output to the web page. Any help on this would really help as I said I'm really new to scripting.

Post what you have so far..

Is this for a school/class project?

this is something I'm working on at my internship.
[code]
$command = "./verify $mfg $image;
[code]
where $mfg and $image are arguments I'm passing to verify. Hope this helps.

Maybe this will help:

Code:

<?php
$var = "/home/";
$command = `ls $var`;
echo $command;
?>
