gpg - gpg-preset-passphrase 安裝

問題： - 當我通過時重複請求密碼show <name of credential>。

做一些Google搜尋，我發現你可以用 gpg-preset-passphrase 做到這一點，但是我不確定從哪裡得到它或者它是否包含在 gpg 發行版中。

這是我正在執行的 gpg 的目前版本。

有誰知道如何安裝 gpg-preset-passphrase？

gpg --version
gpg (GnuPG) 2.0.22
libgcrypt 1.5.3

看起來它已安裝但不能通過gpg-preset-passphrase命令直接訪問，而是/usr/libexec/gpg-preset-passphrase：

/usr/libexec/gpg-preset-passphrase --version
gpg-preset-passphrase (GnuPG) 2.0.22

在我的 Ubuntu 16 安裝中，它位於gnupg-agent包中並放置在/usr/lib/gnupg2/gpg-preset-passphrase.
