What is meant to be treated as unique lines are the numbers in front of each line.
Trying to read a data file and group into separate files if the numbers in front are the same:

One file name with all the "01s".
One file name with all the "02s".
One file name with all the "03s" and so on.

Sorry for the lack of explanation.
