To avoid service account fubar:

# getent passwd | awk -F: '{system("if [ -d /home/"$1" ]; then chown -R
"$3":"$4" /home/"$1"; chmod 700 /home/"$1"; fi")}'

That'll restrict it to just home directories in /home, if they are named
after the usernames, if not, well you will need to write your own test
case.
