How to make a 301 redirect in .htaccess with the substitution of a part of the URL?

Question

htaccess

I'm trying to make a 301 redirect in .htaccess like this:
https://example.ru/catalog/strana-gorod-{123}-{456}/
->
https://example.ru/strana/gorod/
Where:
{123} - a certain predefined character set (only pages containing {123} should be redirected)
{456} - any character set
With the help of google and examples, I can cut /catalog/ from the URL, I can cut {123}-{456}, but the rest I don’t know how to convert part of the URL. How to do it?

Answer 1

RewriteRule ^catalog/(strana)-(gorod)-.*/$ /$1/$2/ [R=301,L]
