      I can think of two paths. Write a script that
      compares an old directory listing with a current
      directory listing and reports changes. Then
      cronjob the script (I'm assuming your using unix).
      I don't see how you'd get a user IP or the
      original file name but you would have the new
      filename.

      The second idea would be to use signal
      processing to alert a perl program that a new
      file has been uploaded. I have no idea how to do
      this. Perhaps a kind unix person from the list can
      tell us if it is possible to use signals in this
      way. This approach would be very OS specific.

      Either of these two approaches does not
      involve programming the CGI. There is no need to
      communicate with a browser to send email via
      send mail.

      (A third approach would be to rewrite the
      script you're "not allowed" to rewrite. Of
      course this depends on why you're not allowed
      to edit it. Think of it as Civil Disobedience,
      but don't lose the job over it.)

      No, it s not a big job if there are only 100 files. You don t need to compare the content of the files but only their names. You just need to compare an array

        You don't need to compare the content of the files but only their names.

        You just need to compare an array with 100 file names taken from a text file
        that keeps the old file names with the current list of file names taken from
        that directory.
        But it would be much more simple just to add a few lines of code to the
        script used for uploading.

        This would create exessive CPU usage on the server. Especially since
        there are 100's of other files to compare against (many large). Its
        kind of like using a drill press to punch a hole in paper :) But
        your right, it can be made to work... In the past, I've only used
        cron to send me logs (error & access) every 3:am.

        There must be a cleaner (simpler) way of doing this. Maybe its time
        to re-code the whole entire thing from scratch :-O

          broke :)

          But to be quite honest with you, this automated "sendmail" script is
          to speed up the work that I need to do. It my gain, not theirs. I
          could sneak the code into the original, but that is not my style :-)
