hello Dan,
if you run the script as root then it is not problem to add an entry in a
read only file. you do not need to change permissions. here is a small
example of a script that will add an entry in your /etc/hosts file:
#! /bin/bash
HOSTSFILE=/etc/hosts
echo -n "Type the new host entry in the form {<ipaddress> <hostname>}: "
read -e HOSTSENTRY
echo "$HOSTSENTRY" 1>>$HOSTSFILE
hope this helps
Stoyan
