Apache mod_rewrite URL redirect script

I wrote a bash script to automate the Apache (mod_rewrite) URL redirection. It supports 3 types of redirection:

– One to One: eg. From http://jackiechen.local/mylab To http://jackiechen.org./mylab

– Any to One: eg. From http://jackiechen.local/* To http://jackiechen.org

– Any to Any: eg. From http://jackiechen.local/$1 to http://jackiechen.org/$1

The script can be downloaded from here

Note: I tested the script in my local, so the script spoof the domain to local in the hosts file. Remove that part if the fqdn can be resolved.
