Test ERC20 with Truffle

Hello, I ask you, I get a syntax error when I place this command

$ mkdir -p build/contracts/
$ cp node_modules/@openzeppelin/contracts/build/contracts/* build/contracts/

Could you help me find the error, thanks in advance, greetings.

$ cp node_modules / @openzeppelin / contract / build / contract / * build / contract /

Why do you want to do this step?

@GabrieelPzg What syntax error do you get when you hit this? Also, just making sure, you’re doing this on a Linux/Unix based system, correct?
