Shell name origin

1. Introduction

Shell, the Chinese name shell, is used to describe the relationship between the user, the operating system, and the hardware.

The computer can not operate without hardware, but the user can not directly operate the hardware, the operation of the hardware only through a "operating system (Operating system)" software to control. In fact, the Linux we are talking about every day is strictly an operating system, which we call "core (kernel)". However, from the user's point of view, the user is not able to directly manipulate the kernel, but through the kernel "shell" program, known as the shell, to communicate with kernel. This is also the kernel and shell of the image naming relationship.
