htaccess help

[kitdang]

I have a website that I want to retire. Before I shut everything down, I like a splash page that tell users the site is closed. How do I redirect all the pages on that site to a splash page using htaccess?

Thanks

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/shutdown.html
RewriteRule .* http://domain.com/shutdown.html [R=301,L]

Thanks David. So those 3 line of codes are all I need on the htaccess page? How about DirectoryIndex ?

Directory index isn't needed because any request for anything other than /shutdown.html will be redirected to shutdown.html.
