What are the command line options to encrypt to the default key?

~$ echo "" | gpg --batch -e
gpg: no valid addressees
gpg: [stdin]: encryption failed: no such user id

grep and cutting the USER_HINT status-fd output isn't the ugly part. It
is more the "signing with an invalid password-fd and then hope the gpg
spit out the key-id as a hint" - part. It feels naughty ;-)

Doesn't work either.

~$ gpg2 --gpgconf-list

~$ gpg2 --version

At least I get the location of the config file somewhat platform

Ciao, Imi.
