Problem with the passthru function

Hello All, I have a small php file (test.php) whose code is shown below: <?php $retval=1; $command='/bin/ls'; passthru($command, $retval); print("Exit status: " . $retval); ?> This test.php works fine when I execute from command prompt as "php test.php", but when I access it through web browser, it seems not to be working fine, I get an exit status of 127 (which means command not found). I checked for permissions of ls, gave full path, but still it is failing. Can anybody help me in indentifying what is the potential problem? Thank you, Venkatesh ps: Sorry if this is the wrong mailing list. I have subscribed to this list, so posting here. __________________________________________________ Do You Yahoo!? Tired of spam?
