Mass redirect htaccess how to do?

Question

Joomla

Good afternoon. There is an online store on Joomla, Joomshopping.
Now one product has three types at once - site/catalog/product
and - site/category/product
and - site/category/subcategory/
product goods
In general, you need to leave only the first option.
Couldn't figure it out. Helpeeee
I tried to do something like:
RedirectMatch 301 ^/$1/$2/(.*) /catalog/$1
but I don't have enough knowledge

Answer 1

RedirectMatch 301 ^(?!/catalog/)(/[^/.]+){2,3}$ /catalog$1
