lakeview ok % gpg --fingerprint --list-keys --with-colons | awk -F: '/^pub:/ { cur = $10 } /^fpr:/ { if (length($10) == 32) print cur }

This works because v3 keys[0] use MD5 as a fingerprint algorithm, which
is 128 bits long (and 32 hex characters) while v4 keys use SHA1, which
is 160 bits long. It only prints out one of the UIDs on the key, not
all of them.

[0] And v2, but for practical considerations, v2 keys are identical to
v3 keys, except that nobody uses v2 keys anymore.
