If it is a trivial count, then commands like wc can give you this, however I think the easiest way using awk (if you are really doing some processing of the data in awk) is to have a count incremented each time you read a record, then in the END section, display the count.
Would this work for you?:-
Obviously adjust it to your preferences. The above will print a line number for every record read AND the final record count, so this might not be what you want. I would only go with awk if you are doing some other processing. wc is far simpler.
