Regular expression to change pattern?

Question

Regular Expressions

Good afternoon. On the site, we change the url address for products and sections. It was respectively /catalog/section_code/, /catalog/section_code/product_id/. New page templates take the following form: /catalog/books-section_code/, /catalog/book-product_id/. I'm trying to compose a regular expression for these patterns, to redirect from the old address to the new one. Addresses like /catalog/books-text/.../ and /catalog/book-text/ should be excluded from the redirect
rule 30987/
It works as expected, but there is a nuance, that in the group I get "bookss-psihologiya/30987", but I need to get it without an id, how can I change it?

Answer 1

To exclude "book-" and "books-" you need to catalog/add after(?!books?-)

RewriteRule ^(catalog)/(?!books?-)([^/]+)/$        /$1/books-$2/ [R=301,L]
RewriteRule ^(catalog)/(?!books?-)[^/]+/([^/]+)/$  /$1/book-$2/  [R=301,L]

Or

RedirectMatch ^/(catalog)/(?!books?-)([^/]+)/$        /$1/books-$2/
RedirectMatch ^/(catalog)/(?!books?-)[^/]+/([^/]+)/$  /$1/book-$2/
