This is not exactly what you are asking for, but this is from
a petty much a been-there/done-that many years ago. Typing in
the logic from memory:
rcfiles="/etc/inetd.conf /etc/syslog.conf /etc/newsyslog.conf"
for rcf in $rcfiles; do
if [ -f ${rcf}.local ]; then
if [ ! -f ${rcf}.base ]; then
if diff ${rcf} ${rcf}.base > /dev/null; then
cp -p ${rcf} ${rcf}.base
fi
fi
cat ${rcf}.base ${rcf}.local > ${rcf}
fi
done
I think you can get the idea.
