Listing changed files between directories

I have two directories:

/home/rose_garden/abs/core and /var/abs/core

they both contain directories like this

acl/
+-----PKGBUILD
atl2/
+-----PKGBUILD
etc

/var/abs/core is rsynced from ArchLinux repos.
and /home/rose_garden/abs/core is my work area.

When Arch changes or updates the PKGBUILD file I would like to get a list of
changed files so I can rebuild my files based in /home/rose_garden/abs/core
Simply rsync between the two directories won't work as I need to make some
changes before using the "new/updated" PKGBUILD file.

I would also like to include any new files that don't reside
in /home/rose_garden/abs/core but are in /var/abs/core as they represent
new software packages placed into the repos.

I would like the list to contain only the files that where updated or
changed.

Comparing
/var/abs/core/acl/PKGBUILD to /home/rose_garden/abs/core/acl/PKGBUILD
and if /var/abs/core/acl/PKGBUILD changes place an entry into a file as in
/var/abs/core/acl/PKGBUILD updated or something similar.

I tried diff but it did not work out as there was too much data I am looking
for just a simple list.

Thanks

I assume that by "changed" you mean "having different hash" or something
like that. Try this:

#!/bin/bash

export H=/home/rose/garden
export V=/var

find "$V/abs/core" -type f -name PKGBUILD -exec bash -c '
m1=$(md5sum "$1"|cut -d " " -f1)
m2=$(md5sum "${1/#$V/$H}"|cut -d " " -f1)
if [ "$m1" != "$m2" ]; then
echo "$1 updated"
fi' sh '{}' \;
