Hi Monks!
I have a big file that has lines like the following:
IIIIIIIIIIIMMMMMMMMMMMMOOOOOOOOOOOOMMMMMMMMMIIIIIIIII

[download]

I want to count the M substring occurrences in each of these lines, and I do it with this snippet:
while(<>)
{
  $count=0;
  while($_=~/(M+)/g)
  {$count++;}
  print $count;
}

[download]

Is there a faster way to do this? Just curious..
