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.
Depends on the distro, but most use wither bash or sh.
The Z shell is a Bourne-compatible shell for Linux and Unix systems.
bash (Bourne Again Shell) is the default shell in most Linux distributions. It was created as part of the GNU project.
It can depend on which shell environment you are using, but what I use is: function something { # body of routine } # call the function something
Shell is the bridge between Kernel and User.
