That is pretty odd, as you seem to have covered the Usual Mistakes... I guess my next move would be to try: if (file_exists('/bin/ls')){ echo "Okay, /bin/ls does exist.<br />\n"; } else{ echo "Hmmm... PHP says /bin/ls does not exist.<br />\n"; } if (is_executable('/bin/ls')){ echo "Okay, /bin/ls is executable.<br />\n"; } else{ echo "hmmm... PHP says /bin/ls is not executable.<br />\n"; } and so on... Try every which way from PHP to check out /bin/ls to see if it is there. I suppose it's also possible that the default Environment for PHP is attempting to ls a directory for which you do not have access... Try using '/bin/ls /full/path/to/your/web/tree' instead. -- Like Music? http://l-i-e.com/artists.htm
