Unfortunately, that's not what he was asking for, which is to look for
the pattern "big <foo>" where all the possible <foo>s are unknown and
report on all the <foo>s that were found.
So something like:
while (<>) {
while (/big\s+(\w+)/g) {
$count{$1}++;
}
}
foreach $word (sort(keys(%count))) {
print "$word: $count{$word}\n";
}
ought to do the trick. Play with $/, etc if you want to allow big and
<foo> to be across a newline from each other.
