deleting files created via cgi
> How would I delete a file that is created outside of the script?
You can't, because your script is running under apache that is "nobody", i.e. from a user that is different from the user you login into the server.
You have to chmod 666 (i.e. -rw-rw-rw) the files from the script after their creation.
To delete files that you have created before this "patch", write another CGI that sets all the existing files to 666. Then you can delete it from the login user.
