Dear List - I'm lost on this one - This works - $out = system("ls -l ",$retvals); printf("%s", $out); This does - echo exec("ls -l"); This does not - if( !file_exists("/var/www/orders.txt")); {

     $out = system("touch /var/www/orders.txt", $ret);
     $out2 = system("chmod 766 /var/www/orders.txt", $ret);

Hi Ethan, Is there a reason you're using shell commands to achieve the following: <?php

    $path = '/var/www/orders.txt';
    if( !file_exists( $path ) )
    {
        if( !touch( $path ) )
        {
            echo 'Failed to touch file into existence: '.$path."\n";
        }
        else
        {
            if( !chmod( $path, 0766 ) )
            {
                echo 'Failed to update file permissions: '.$path."\n";
            }
        }
    }

?> Also, why are you setting the executable bit on a text file? :) Cheers, Rob. -- E-Mail Disclaimer: Information contained in this message and any attached documents is considered confidential and legally protected.
