In short, a stray \p before a range (with no preceding range) silently make it only expand to first element. One could argue it's a bug in the rule given, but anyway we should at least warn about it. Showing it with Jumbo here, but I verified same behavior in john proper: Let's say we have this rule, with parallel ranges: $ echo magnum | ../run/john -pipe -stdout -ru::'-[:c] \p[uc] $\p' MAGNUM1 Magnum2 2p 0:00:00:00 0.00% 33.33p/s Magnum2 ...then we decide to drop the case flipping, *but we forget the last \p in there*: $ $ echo magnum | ../run/john -pipe -stdout -ru::'$\p' magnum1 1p 0:00:00:00 0.00% 20.00p/s magnum1 Obviously this output was expected: $ echo magnum | ../run/john -pipe -stdout -ru::'$' magnum1 magnum2 2p 0:00:00:00 0.00% 50.00p/s magnum2 I saw this in someone else's rule (much more complicated) and I think it could be a common enough problem to catch and warn for - or simply treat \p as a no-op in that case. magnum
