Robots txt for a multilingual site?

Question

Search Engine Optimization

Good morning everyone. There is such a question, if I have a trilingual site, I need to register such a directive in the robot to close the page from indexing:

Disallow: /trade-in
Disallow: /ru/trade-in
Disallow: /en/trade-in

or one Disallow is enough : /trade-in ?

Answer 1

Disallow: /trade-in
Disallow: /*/trade-in
