.htaccess RedirectMatch looping?

Question

htaccess

How to make a redirect from a link like myserv/cat1/tag1/af_3fffwfccfeg to myserv/cat1/tag1/ so that the condition doesn't cycle.
Any characters can be in the destination directory.
Those. you need to make the condition work only if there is something else after /cat1/tag1/, and if there is nothing, then the condition should not work.
I tried this:
RedirectMatch 301 /cat1/tag1/[\S*] myserv/digital/igromania/ I
also tried this regexr.com?2ur8c
It doesn't seem to highlight the second line, but when I apply this rule, I get a cyclic redirect.

Answer 1

RedirectMatch /cat1/tag1/([\S]+)$ site.ru/cat1/tag1/

Answer 2

I suspect that it is not [\S*], but [\S+], because '*' is 0 or more, and you need 1 or more, and this is '+'.
