Assuming you're using gpg 2.2.7 or above...
gpg --batch --yes --passphrase="pw" --pinentry-mode loopback -o zz -esr user at domain.com zz.gpg
This can only be used if only one passphrase is supplied. Obviously, this
is of very questionable security on a multi-user system. Don't use this
option if you can avoid it. Also, unless you add yourself to the list of
recipients, you won't be able to decrypt the file even if you possess
the original unless you hold the private key for user at domain.com
