Software :: Making A Bash Script To Read In Different Files And Rename Output Files?

Until now i haven't had to dabble with bash scripts.

I have a program that reads in data files. These are named datafile01_R, datafile01_G, datafile01_B, they then increment, so datafile02_R etc i have about 600 of these. the program reads in 3 data sets at a time from each run, so files_01 r, g, and b.

The program then does its magic, and outputs about 40 different files, depending on the file, they gone to folders named R, G, B, psa, or tracking.

The program itself has configuration files to say where the files should gone when analyzed, there is also the config files that reads in the data sets.

At the moment i have to run one set of data, then go in and manually change the input file location, and run again. But, doing this, even though a different data set, the new set overwrites the old set in one of the output folders. So i need a way to increment the output filenames after they are written and before the program is run again with the new data set.
