If you want to know the number of parameters supplied in the script, then you can use the $# to get the total. Based on the preceding example, the $# will be equal to three since we're passing three arguments.

If you add the following line after the printf line:

printf "%s %d\n" "The total number of params =" $#

you should see the following in the terminal window:

root@kali:~# simpleadd.sh 2 4 4 ######################## The total is = 10 The total number of params = 3 ########################
