Here is what I get so far. Of course, you'll surely have other replies that will do the same in a simpler way Smilie
Code:
#!/bin/sh

sort -t',' -k2,2n file | uniq -c -s4 > tmp

while read line; do
  echo "$line,$(grep ${line##*,} tmp | awk '{print $1}')"
done < file

exit 0

Your data file need to be named file, in the same directory as the script.
I use a tmp file to keep the number of occurences of the second field.
