Thanks for all the response's...
Well it looks like most people really use /usr/sbin/sys-unconfig.

But I really wanted a shell script so I created one:

#!/bin/sh
#
# I called it hostchange. If you have more than one NIC card you
# would need to edit the script...
# You could also add lines to edit IP, Log files, etc...
#
if cat /etc/hostname.hme0 >> /dev/null 2>&1
then
#
OLDHOST=`hostname`
echo Current hostname= $OLDHOST
echo
echo Enter the new hostname:
read NHOST
echo
#
echo The new hostname will be $NHOST.
#
echo
echo Is this information correct? [Y/N] Default is [Y]
read ANS
case $ANS in
YES|[Yy]es|[Yy]|"")
    echo OK, we will continue...
    ;;
NO|[Nn]o|[Nn])
    echo Lets start over...
    sleep 3;clear;./hostchange;exit
    ;;
*)
esac
#
echo Editing hosts files:
echo /etc/hosts
echo /etc/net/ticlts/hosts
echo /etc/net/ticots/hosts
echo /etc/net/ticotsord/hosts
echo /etc/motd
echo /etc/nodename
echo /etc/hosts.allow
echo /etc/mail/sendmail.cw
echo /etc/mail/local-host-names
echo /etc/hostname.hme0
echo
echo to read new name: $NHOST....
#
cp -p /etc/hosts /etc/hosts.orig
sed -e s/${OLDHOST}/${NHOST}/g /etc/hosts.orig > /etc/hosts
cp -p /etc/net/ticlts/hosts /etc/net/ticlts/hosts.orig
sed -e s/${OLDHOST}/${NHOST}/g /etc/net/ticlts/hosts.orig >
/etc/net/ticlts/hosts

sed -e s/${OLDHOST}/${NHOST}/g /etc/mail/local-host-names.orig >
/etc/mail/local-host-names
#
sleep 2
echo
echo Done....
echo Dont forget to reboot....
else
echo Your hostname.interface is not /etc/hostname.hme0. Please edit script for
your interface and rerun.
