Solve : Need help writing a code in UNIX?

1.	Solve : Need help writing a code in UNIX?
Answer» I'm writing a UNIX shell script and I need to write a code USING a text file. For each LINE in the text file, the THIRD field RANGES from 2 through 6. 2=Sparkling, 3=Foritified, 4=Sweet, 5=White, and 6=Red. I need to make it so that if the third field is a 2, it WOULD add 1 to the counter "Sparkling" and so on. How can I do this? Thank you for any help
