Redirect with . htaccess

Question

Would anyone know to assist me in changing a friendly URL.

Example:

RewriteEngine On
RewriteRule ^nome-da-nova-url-([A-Za-z-]+)\.htm$ url.php?url=$1

I would like everything that is on www.meusite.com/nomedaurl.htm were for www.meusite.com/newname-url-starname-starname.htm.

If there is a possibility to redirect:

RewriteRule ^([A-Za-z-]+)\.htm$ url.php?url=$1

To:

RewriteRule ^nome-da-nova-url-([A-Za-z-]+)\.htm$ url.php?url=$1
