Help with Bash Script

Hi all,

I'd like to write a bash script to help me manage photo files on our webserver. The website is for a real estate company that gets listing updates daily. New photos are added each day, and updated text files are sent as well with a list of current active records.
I have to find a way to compare all of the photos with all of the active records. If a photo does not have an associated record (because it's been deleted), then delete that photo. I imagine I'll have to run this script once a week so the pictures don't keep piling up, but I can set a cron job to do that.
Each picture is named with a number that corresponds to a field in the record. Oh, and for added fun, there are 6 different tables. I figured I could select all of the property numbers from all of the db tables and append them to a text file. Then I'll have to find some method to compare the photos with the entries in the text file, and whichever photo doesn't have a corresponding entry - just delete it. Does that sound like the easiest way? Any help writing a script to do that would be appreciated.
So far I've been able to write the results of one Select query to a temporary text file that I don't know how to access. I get permission errors when trying to write to a text file in any other directory & I don't know how or where to check the permissions for that. Consider me stuck on this one.

SMOKEPING_CGI(1)						     SmokePing							  SMOKEPING_CGI(1)

NAME
smokeping_cgi - SmokePing webfrontend OVERVIEW
This script acts as a 'website' for your SmokePing monitoring operation. It presents the targets you are looking at in a tree structure and draws graphs as they are required by people looking at the pages. DESCRIPTION
To get smokeping_cgi going, you need a webserver which allows you to run CGI or better FastCGI scripts. The system must be setup so that the cgi process is allowed to write to the image caching area as defined in the config file. This script runs fine as a normal CGI, BUT it will appear to be very slow, because it does a lot of things when starting up. So if the script has to be started a fresh on every click, this is both slow and a tough thing for your webserver. I therefore strongly recommend using FastCGI. Please refer to the installation document for detailed setup instructions. SETUP
There is a sample htdocs directory in your smokeping installation root. Copy its content to the place where your webserver expects its files. There are also two sample cgi scripts showing how to launch the smokeping cgi in your website. The only difference is the file extension. Adjust the paths in the script and you should be ready to go.
