How to redirect using htaccess from one domain to another?

Question

htaccess

Hello. There was such a problem. 2 domains refer to one site on the server. Those. the sources are the same, and you can get to the site, for example, at the addresses firstdomain.com and seconddomain.com. You need to make sure that if a person comes to the site at http://firstdomain.com, he will be redirected to seconddomain.com with a 301 code. How can this be done with .htaccess? Thanks in advance for your reply.

The answer is found. Maybe someone will help. You need to write the following in htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^firstdomain\.com
RewriteRule ^(.*)$ seconddomain.com/$1 [R=301,L]
