Re: exec command help

what is the output of $results ? print_r($results); try another command, ie. exec("echo hello world", $results); exec("echo hello world > /tmp/test.txt", $results); does that work? does that file aliases.db permissions set as world writeable, or the user.group set to nobody.nobody (ie. whatever your webserver is set to), or does postalias run as suid root ? what Im getting at is maybe the app is being run but doesnt have the permissions to edit the file because of the user.group that is running the app. -- Chris Lee lee@mediawaveonline.com "Nashirak Bosk" <nashirak@mindspring.com> wrote in message news:3B0AB2DA.647ED1F9@mindspring.com... > I am trying to run a something everytime a certain page is loaded.
