No, it's known as a Read-Eval-Print Loop, or REPL.
"Shell" is a kind of REPL for a kind of language, both being optimized to minimize typing required to execute commands and string them together in a pipe. It's good at its job, but it's poor general REPL. Proper programming REPLs are very powerful and very useful tools, to the point I'm pretty unhappy when I have to work in a language without one.
It's known as "shell". It's opposite to programming.
