Others have shown how exec() returns the output. If you use shell_exec() it's the same as using the backticks: <?php echo `whoami`; ?> -or- <?php echo shell_exec("whoami"); ?> You can use single quotes here also, i used double so you can easily tell they are not backticks -- Thanks! -Shawn http://www.spidean.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
