Perl parsing files

If that's the case, you can read each file line by line:. Your specification has a few loose ends; for instance - what if there are more lines in file2 then there are total labels in file1? Do you want the spaces in the first input file ignored? Do you want the spaces in the output file specifically as shown? I've presumed "yes" to most of these questions.

My solution is driven by the second data file - which means that if there are more total labels then there are lines of data, they are going to be ignored.

It also means that if there are more data lines in file2 then there are labels in file1, the program will simply make up the label - No Label? Finally, just in case you want to add these numbers up at some point, I've included but commented the sum function from List::Util.
