Initial Description
Use to quickly list the unique fields in a file AND the number of times the field occurs
e.g. Count how times a resource (eg image) has been resulted in a 404 status by examining the IIS logs.
eg assuming this is the input file: **input.txt** and the source script below is in **count.awk**

will yield
