  • shell script - gpg asks for password even with --passphrase - Unix . . .
    Here is an apparent work around I discovered: echo your_password | gpg --batch --yes --passphrase-fd 0 your_file gpg Explanation: Passing 0 causes --passphrase-fd to read from STDIN rather than from a file So, piping the passphrase will get --passphrase-fd to accept your specified password string
