Question 16/20
Explanation: When you run a 'command' you are actually instructing the shell to run a program. If the hell can
find the program, it will run it. The shell knows how to start the program, but it doesn't know the syntax of the
program/command. If you get an error saying 'incorrect syntax', the error will be coming from
the program.
Incorrect Answers
A: The shell knows how to start the program, but it doesn't know the syntax of the program/command. A shell
error message would be for example, ': Command not found.'.
B: The operating system runs the shell. It doesn't know about specific commands.
D: The kernel is effectively the operating system. It doesn't know about specific commands.
