PowerShell can be started with input redirected in different scenarios. `powershell -Command -` is one scenario where commands are sent to PowerShell, but this is not a interactive shell scenario, it's really a server to run commands from some other process. `powershell -File -` or just regular redirected input means PowerShell is an interactive shell, but command line editing must be done via the redirected standard input handle instead of interacting directly with a console handle. In this scenario, we want to provide a good editing experience. Today, we provide the bare minimum, supporting backspace but no cursor movement. The bug here is that backspace was treated as a backspace in the server mode but should not have been.
PowerShell
Welcome to the PowerShell GitHub Community! PowerShell is a cross-platform (Windows, Linux, and macOS) automation and configuration tool/framework that works well with your existing tools and is optimized for dealing with structured data (e.g. JSON, CSV, XML, etc.), REST APIs, and object models. It includes a command-line shell, an associated scripting language and a framework for processing cmdlets.

Downloading the Source Code
The PowerShell repository has a number of other repositories embedded as submodules.
To make things easy, you can just clone recursively:
git clone --recursive https://github.com/PowerShell/PowerShell.git
If you already cloned but forgot to use --recursive, you can update submodules manually:
git submodule update --init
