通过命令行将密码多次传送到命令

通过命令行将密码多次传送到命令

我正在运行Ubuntu 18.04，bash我想将密码传递给运行的命令sudo，但是一旦运行，即密码通过管道传输到命令（python3运行命令app），它会要求输入密码两次，我正在尝试通过以下方式做到这一点：

echo "passphrase" | echo "passphrase" | echo $password | sudo command

但它似乎不起作用。

该命令的输出如下：

sudo python3 app.py
Enter PEM pass phrase:
 * Serving Flask app "app" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on https://127.0.0.1:443/ (Press CTRL+C to quit)
 * Restarting with stat
Enter PEM pass phrase:
 * Debugger is active!
 * Debugger PIN: 157-564-730

有谁知道如何通过unixbash 脚本中的命令来执行此操作？
