in reply to How do I process multiple files in parallel?

Not that I'm deliberately trying to golf this thing, but...
undef $/; # so <> will sluurp each file on the command line into $_ $\ = "\n"; $, = " "; print /Sen = (\S+)/, /Acc = (\S+)/, /Cor = (\S+)/ while <>;
Then redirect output when you call it.
