Thanks for the responses you guys are top notch. I have made a few modifications to get this working recursively using edgarvm's example. I also incorporated JerryHone's idea about dealing with non-existent files

Code:
#!/bin/bash

# setup folders for our different stages
DIST=/var/www/localhost/htdocs/dist/
DIST_OLD=/var/www/localhost/htdocs/dist_old/
DIST_UPGRADE=/var/www/localhost/htdocs/dist_upgrade/

cd $DIST

list=`find . -type f`

for a in $list; do
   if [ ! -f "$DIST_OLD$a" ]; then
        cp --parents $a $DIST_UPGRADE
      continue
   fi
   diff $a $DIST_OLD$a > /dev/null
   if [[ "$?" == "1" ]]; then
        # File exists but is different so copy changed file
        cp --parents $a $DIST_UPGRADE
   fi
done

Thanks for the advice.
Regards,
Brandon

PBUILDER-DIST-SIMPLE(1) 				      General Commands Manual					   PBUILDER-DIST-SIMPLE(1)

NAME
pbuilder-dist-simple - simple multi-release pbuilder wrapper SYNOPSIS
pbuilder-<dist> operation [...] DESCRIPTION
pbuilder-dist-simple is a wrapper that makes it easy to use pbuilder with chroots for many different Ubuntu distributions. If you need more features than pbuilder-dist-simple provides, have a look at pbuilder-dist(1). USAGE
Create one symlink to pbuilder-dist-simple for each distribution for which you want a build environment, naming them like "pbuilder-lucid", "pbuilder-natty", etc. Replace operation with the action you want pbuilder-dist-simple to do (create, update, build, clean, login or execute). EXAMPLES
pbuilder-natty create Creates a pbuilder environment for Ubuntu Natty. pbuilder-lucid update Updates an existing Ubuntu Lucid environment. pbuilder-lucid build ./sample_1.0-0ubuntu1.dsc Builds the specified package on an already existing Ubuntu Lucid environment. FILES
By default, pbuilder-dist-simple will store all the files it generates in ~/pbuilder/. This can be changed by modifying the BASE_DIR value on the top of the script to any other directory you want. If the directory doesn't exit, it will be created at runtime. SEE ALSO
pbuilder(1), pbuilderrc(5), pbuilder-dist(1) AUTHORS
pbuilder-dist was originally written by Jamin W. Collins <jcollins@asgardsrealm.net> and Jordan Mantha <mantha@ubuntu.com>, and this man- page by Siegfried-A. Gevatter <rainct@ubuntu.com>.
