Apache.htaccess redirects subdomain to parent domain

Question

I want to redirect my subdomain

http://xyz.domain.com at http://domain.com

and similarly any subdirectories such as

http://xyz.domain.com/abc at http://domain.com/abc

I do not want redirects for all of my subdomains, but specifically for this.

thanks for the help

RewriteCond %{HTTP_HOST} ^xyz\.domain\.com$
RewriteRule ^/(.*) http://domain.com/$1 [redirect,last]

Answer 2

The easiest way to redirect a subdirectory to a domain:
