Entrada de entrada em um comando? [duplicado]

Question

Estou executando um comando por meio de um programa que precisa criar uma conta do OpenVPN. Depois de colocar esta linha para começar a fazer a conta:

cd /etc/openvpn/easy-rsa; . ./vars; ./build-key username

Eu preciso que ele não coloque nenhuma entrada 10 vezes [como pressionar enter,] e pressione y duas vezes. Precisa estar tudo nessa linha. Isso é possível? Agradecemos antecipadamente.

EDITAR:

root@suffice-vpn:~# cd /etc/openvpn/easy-rsa; . ./vars; <<<$'\n\n\n\n\n\n\n\n\n\nyy' ./build-key username
NOTE: If you run ./clean-all, I will be doing a rm -rf on /etc/openvpn/easy-rsa/keys

Sign the certificate? [y/n]:CERTIFICATE WILL NOT BE CERTIFIED: I/O error
root@suffice-vpn:/etc/openvpn/easy-rsa#

Como você pode ver, ele passa pelo processo preenchendo os espaços em branco [mantendo todas as informações que eu quero que permaneçam as mesmas], mas eu recebo este erro de E / S.

Eu resolvi usando este comando:

cd /etc/openvpn/easy-rsa; . ./vars; ./build-key --batch username
