The generalized form would be (golfed down a bit) for any number of files
perl -ne'BEGIN{$p.=-$_."+"for-@ARGV+1..-1;$p.=0}print if($s{$_}.=@ARGV +)=~/$p$/'

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
