Maybe send output through `sort | uniq -c` (or write the equivalent Ruby code). I was too lazy to write a parser for the approximately twelve different ways in which a primary/secondary split is indicated. The crown goes to a guy called “Unassigned” (341 registries), with 33 Russ Housley 34 Margaret Wasserman 34 Roman Danyliw, Takeshi Takahashi 37 Joe Macker as runner-ups (Russ has a few more where he is primary). I was surprised by the number of registries my name is on :-) Grüße, Carsten
