I am not sure if I understood what you want, since the 2nd post for line "adam,12345" differs from the example in post 1. There are 2 new fields that weren't there in post 1.
Seems there is some inconsistency between examples of input and output.

Anyway, giving a blind shot taking the 1st example as input without the -----[n]:
Code:
$ awk 'NR > 1{_[$1]++} END{for(a in _){print a ","  _[a]}}' infile | sort -nt, -k3| tail -1
adam,12345,3

The cat in your code is not needed.

NAME
pbmupc - create a Universal Product Code bitmap SYNOPSIS
pbmupc [-s1|-s2] type manufac product DESCRIPTION
Generates a Universal Product Code symbol. The three arguments are: a one digit product type, a five digit manufacturer code, and a five digit product code. For example, "0 72890 00011" is the code for Heineken. As presently configured, pbmupc produces a bitmap 230 bits wide and 175 bits high. The size can be altered by changing the defines at the beginning of the program, or by running the output through pnmenlarge or pnmscale. OPTIONS
The -s1 and -s2 flags select the style of UPC to generate. The default, -s1, looks more or less like this: |||||||||||||||| |||||||||||||||| |||||||||||||||| |||||||||||||||| 0||12345||67890||5 The other style, -s2, puts the product type digit higher up, and doesn't display the checksum digit: |||||||||||||||| |||||||||||||||| 0|||||||||||||||| |||||||||||||||| ||12345||67890|| SEE ALSO
