## Overview

This is a small interactive C# shell. The user enters a line, the shell tokenizes it and dispatches built-in commands or launches a process. Built-ins support directory changes, directory creation, console clearing, and exit. The single source file also owns command errors and process waiting; the repository provides no evidence of additional subsystems.

Main entry points: [`Program.cs`](https://github.com/noufel882/simple-shell-using-c-sharp/blob/main/Program.cs) (Shell Loop)
