in thread Using less memory with BIG files

for the second part, I store each line as a hash key, then I don't really know what to do after that?

would it make more sense if i set each group to a hash with the key being the group name and the value being the number? problem is there would be repeats for the IDs so i don't know what can i do.

sorry but im still kinda new to this D:
