(d) $$

I got this question by my college professor while I was bunking the class.

Origin of the question is Shell Programming using read Command and Command Line Arguments topic in division Essential Shell Programming of Unix

Answer 1

Correct choice is (c) sh

The explanation: We know that shell scripts are executed by a child shell. But we can also explicitly spawn a child of our own choice by using the sh command along with script name as an argument. When used in this way, the interpreter line is ignored by the shell.
