Hi I have written shell script for both points. Please check below.

#!/bin/sh

# prints the calling proram name

echo "calling program name "$0;
echo "Number of positional parameters:"$#;   # Prints the no of parameters
echo "Parameters ares: "$@;

Output:

./all.sh 1 2

calling program name ./all.sh
Number of positional parameters:2
Parameters ares: 1 2
