This was more of an FYI note, I found how to resolve the issue https://www.gnupg.org/documentation/manuals/gnupg/Unattended-GPG-key-generation.html

Not sure what is different, but the code given on that page worked :)

Add %no-protection if you need to generate passwordless keys. This also prevents the pinentry to pop up.

Using Process Substitution can be support indentation

gpg --full-gen-key --batch <(echo "Key-Type: 1"; \
                             echo "Key-Length: 4096"; \
                             echo "Subkey-Type: 1"; \
                             echo "Subkey-Length: 4096"; \
                             echo "Expire-Date: 0"; \
                             echo "Name-Real: Root Superuser"; \
                             echo "Name-Email: root@handbook.westarete.com"; \
                             echo "%no-protection"; )

Quick question for you, do you know if it's possible to use --batch to create a master key and subsequent subkeys (3 to 4 at a time)?

I want to follow this guide: https://github.com/drduh/YubiKey-Guide and create a script that would create the master key and sub keys at the same time. After some research, I'm left with 'it can only generate 1 subkey' so I'm stuck right now
If you have an idea, could you share it?
