When faced with this kind of problem, I usually start debugging
by removing all the wildcards and checking for the exact pattern
which appears in the output file. In this case I'd replace the
.* with _5 and see if it matches properly. If it does, then I'd
tighten the wildcard. Something like p_[0-9]*
