Shell is not considered an operating system (OS) because it functions as a command-line interface that allows users to interact with the underlying OS rather than being a standalone system itself. It acts as a mediator between the user and the kernel of the OS, enabling users to execute commands and manage system resources. An operating system encompasses a broader range of functionalities, including resource management, file management, and hardware abstraction, which are not provided by the shell alone.
The kernel and the shell are two different parts of the OS or operating system. The shell interprets the commands from input. The kernel houses the heart of the OS like the command files and execute applications.
