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
