What directive should be specified in .htaccess to redirect from one section of the site to another?

Question

htaccess

Good afternoon.
Please tell me what directive to register in .htaccess so that the visitor, getting to one section of the site, is automatically redirected to another. In my case, from the mobile version of the site to the standard one:
From all pages containing
sitename.ru/m/
to the pages
sitename.ru/catalog/
, that is, to change "m" to "catalog".
Thank you!

I asked myself, and I will answer! :))
Pretty simple:
RewriteRule ^ m (/.*|)$ catalog $1 [L,NC,R=301]
