I am trying to invoke awk inside a bash script and passing some bash variables values to it. Is there any way to get a count of these variables and print all which are passed to it inside awk.

No. of variables passed to awk would be dynamic.

Below example

#!/bin/bash
NAME="Dell"
SERIAL="12345"
echo "Hello" | awk -v a=$NAME -v b=$SERIAL ' print a,b '
