G'day EntropyDF,

Welcome to the Monastery.

"File 1 is a CSV seperated log file. For this need the IP address is always in split 8 of the file."

Do not try to write your own CSV parsing code. This is fraught with all sorts of problems and is one wheel that definitely does not need to be reinvented. Use Text::CSV for this task.

"However if I could not rely on that it would be good as there are other log types this coudl apply to."

Abstract your code into a subroutine and pass it the wanted field number. As you've chosen to show no code, I'm in no position to indicate how you'd modify such code to achieve this. The field number could come from any number of places, such as command line argument, config file, database, etc.; it would presumably be associated with whatever "other log types" refers to.
