find and mail if changes has occured, unix

Question

The following script runs and finds if any new suid has been changed, and redirects the output to a file.

I want to add a mail command in the script, that will send mail to [e-mail]. If changes have been made, add a subject line ("Changes have been made") and attach a file (changes.new). If no changes have been made, add a different subject line ("no changes has been made").

#!/usr/local/bin/bash
if [ ! -f "$/suid.old" ]
then
   find / -perm -4000 -o -perm -2000 > ol.list
else
   find / -perm -4000 -o -perm -2000 > new.suid
   diff suid.old suid.new   > changes.new
fi
