You didn't say anything about there being header lines in your files that need to be ignored, so the code I suggested in post #5 in this thread would give you a count that is 1 more than the number of different customer IDs found in all of the .csv files in the directory in which you run that script. I assume that you can manually subtract 1 from the result printed or change the line in the code that prints the value of c to instead print c-1 to get the results you want.
Did you try running the code I suggested? Do you have some reason to think it is not doing what I described above?
If what I provided is not sufficient, please explain what it is doing wrong AND show us exactly the output you want from the sample input you provided.

makesh
MAKESH(1) General Commands Manual MAKESH(1)
NAME
makeSH - a .SH script maker
SYNOPSIS
makeSH files
DESCRIPTION
MakeSH examines one or more scripts and produces a .SH file that, when run under sh, will produce the original script. The .SH script so
produced has two sections containing code destined for the output. The first section has variable substitutions performed on it (taking
values from config.sh), while the second section does not. MakeSH does not know which variables you want to have substituted, so it puts
the whole script into the second section. It's up to you to insert any variable substitutions in the first section for any values you want
from config.sh.
You should run makeSH from within your top-level directory and use the relative path to the file as an argument, so that the "Extracting
..." line printed while running the produced .SH file later on will give that same path.

BUGS
It could assume that variables from metaconfig's Glossary need to be initialized in the first section, but I'm too lazy to make it do that.
