Changing htaccess page?

Question

htaccess

Hello!
I'm trying to change the page. When you go to /catalog/el195 to show test2.html
RewriteRule ^.*$ test2.html [L]
- all pages are replaced. Works
But with this design
RewriteRule /catalog/el195 test2.html [L]
It already stops working. Where is the mistake?

Answer 1

Redirect 301 /catalog/el195 test2.html
