Fetch all GPG keys that are currently missing in your keyring

gpg --list-sigs | sed -rn '/User ID not found/s/^sig.+([a-FA-F0-9]{8}).*/\1/p' | xargs -i_ gpg --keyserver-options no-auto-key-retrieve --recv-keys _
For instance, if people have signed your key, this will fetch the signers' keys.

  • The original command doesn't work for me - does something weird with sed (-r) and xargs (-i) with underscores all over... This one works in OSX Lion. I haven't tested it anywhere else, but if you have bash, gpg and perl, it should work. Show Sample Output

    for i in `gpg --list-sigs | perl -ne 'if(/User ID not found/){s/^.+([a-fA-F0-9]{8}).*/\1/; print}' | sort | uniq`; do gpg --keyserver-options no-auto-key-retrieve --recv-keys $i; done

What Others Think

doesn't work for me, I get: sed: -e expression #1, char 50: Invalid range end

The invalid range is from a-F in the character class. It should read [a-fA-F0-9]{8}. There are quite a few problems with the original version.
