echo传递值

[罗非鱼]

gpg -ase -r 0xc1868032 -u '[email protected]' file

You need a passphrase to unlock the secret key for
user: "test (key) <[email protected]>"
2048-bit RSA key, ID C1CD62CB, created 2011-05-17

user: "test (key) <[email protected]>"
我输入密码后,指令成功运行,用echo传递数值,不成功.

echo "mykey" | gpg -ase -r 0xc1868032 -u '[email protected]' file
运行后,还是出现
You need a passphrase to unlock the secret key for
user: "test (key) <[email protected]>"
2048-bit RSA key, ID C1CD62CB, created 2011-05-17

You need a passphrase to unlock the secret key for
user: "test (key) <[email protected]>"

请问,如何修改这个语句?

读取密码一般是直接读终端设置的，所以你需要用 expect。

有的程序为了安全，
在输入密码等重要信息的时候，
要求必须使用键盘输入，而不能使用管道及重定向。

大约是指定了/dev/tty

这是本质。
