Ok, having my home connectivity restored at least temporarily I've now signed all the user keys that /home/*/pubkey.asc found. That was a few! I'm rather flabbergasted how can gpg not have an option "list all keys that match criteria X". Maybe I'm just blind. It seems to me that the easiest way to sign a ton of keys is to: 1) gpg --import /home/*/pubkey.asc 2) in other window gpg --list-sigs | grep -v "User id not found" | less and look for keys we haven't signed 3) gpg --sign <paste-from-other-window>, repeat until 4) gpg --send-keys 4) gpg --armor --export > ... Not all that automatable. Cheers, -- Nikodemus Siivola
