You could use something like:
getent passwd | awk -F: '{if ( $3 >= 500 ) print $1}' | while
in place of the cat /etc/passwd line. The awk section give you users
with UID 500 or greater. You may have to change it to 100, depending
on the UID of the first non-system user. You could also test the
home directory to see if it is /home/<something>.
