I'm assuming this is to check for defaced websites or websites that have
extra pages added for nefarious activities (scams, - etc)?

If I were to do this... It would be part of a "Site Backup" routine....
You only need to make a Backup if there has been a change.
Usually - the pages for a site have to be in a well defined area (the
DocumentRoot).  Find and compute a Checksum for all files. Compare to
the last time, and if there are changes (or no last time), take a
backup... or in your case, send an e-mail.

To Create your checksums to compare against...

for web in * 
do 
find $web/web -type f -print0 | xargs --null md5sum > $web/.csum
done

* I put all webs in "/home/www/<WebSiteName>/web"
* You need the '-print0' and '--null' because people put spaces in file
names....

Run something similar - but output into say ".csum-new" and
then compare the .csum and .csum-new files.... per website.

for web in * 
do 
find $web/web -type f -print0 | xargs --null md5sum > $web/.csum-new
cmp -s $web/.csum $web/.csum-new || (
echo "Someone Changed something"
diff $web/.csum $web/.csum-new
) | mail -s "Website $web has changed" foo at adm.com
done

Send an e-mail on a difference.

Anyway - you should get the idea.....
