Yes it is on a Linux system. I have done a little research and I am having a hard time finding info about executing shell commands with php. This seems like a very interesting possibility being able to use shell commands. Any info you could point me to would be very appreciated. I did find this piece of code that doesn't work for me. Maybe it is missing something? <?php $mstrng = shell_exec('du -sc home/joeuser/www/testdir/'); print "$mstrng"; ?> It produces "0 total" and I know there is more then 11 kb of file in the directory. I tried it pointed directly at the file in the directory and I also tried the "du -h". Thank you so much for your response.

I would like to be able to get the size of a directory with sub directories under it. Will I need to loop through file sizes to get the total directory size?
