how to redirect a subdomain with child directory to new url using htaccess

Question

I have a old website which used subdomains for each pages, i'm moving to new site and want to redirect the most of the links to the new pages.

I searched a lot but didn't find anything.

For instance i will be redirect this url to this:

blog.test.com/12/09/test-2 to test.com/blog/test-2 How it possible? I tried this

or just simply redirect all the blog.test.com with whatever query they have to the new page?

blog.test.com/whatever?whatever to test.com/blog

You can use this code in your DOCUMENT_ROOT/.htaccess file of test subdomain:

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(blog)\.(test\.com)$ [NC]
RewriteRule ^\d{2}/\d{2}/(.+)$ http://%1/blog/$1 [L,R=302]
