Shell is the bridge between Kernel and User.
A shell in Linux is the interpreter that provides a commandline interface (CLI). There are many kinds of shells.
The Z shell is a Bourne-compatible shell for Linux and Unix systems.
Linux Internals is a book about how Linux works.

Strictly speaking, a "shell" is simply the interface between the user and the rest of the operating system. In that definition not all shells on Linux are command lines. However, most day-to-day usage of the term "shell" does refer to command line user interfaces. Finally, "Linux shell" is not a thing. Linux is an operating system, specifically a kernel, not a shell. Most Linux distributions use BASH, but I personally prefer ZSH.
