Openssl command switch for automation of certificate signing

I know that when working with openssl you can bypass the interactive input by:

• -passin pass:whatever
• -passout pass:whatever
• -subj "/C=pa/ST=pa/L=pa/O=pa/OU=pa/CN=pa"

However when signing a certificate, like with:

openssl ca -config intermediate/openssl.cnf 
        -passin pass:whatever 
        -extensions usr_cert -days 375 -notext -md sha256 
        -in intermediate/csr/www.example.com.csr.pem 
        -out intermediate/certs/www.example.com.cert.pem

I need enter "y" twice:

            ....
            X509v3 Authority Key Identifier: 
                keyid:96:7B:52:E6:FC:53:53:F0:F3:D1:B3:EB:FB:5C:95:4D:73:BD:B8:5D

            X509v3 Key Usage: critical
                Digital Signature, Non Repudiation, Key Encipherment
            X509v3 Extended Key Usage: 
                TLS Web Client Authentication, E-mail Protection

Certificate is to be certified until Jul 12 14:00:14 2017 GMT (375 days)
Sign the certificate? [y/n]:y


1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated

Is there a openssl commandline switch that automates this?
