Observe que a funcionalidade zipinfo é, na verdade, parte do programa unzip (os dois binários geralmente são idênticos ou são links um para o outro). Você pode invocar unzip -Z para obter a funcionalidade de zipinfo . Portanto, se a sua instalação não deve ter um zipinfo binário, você pode usar unzip -Z .
