A few months ago, Azure CLI 2.0 was released. It provides a command line interface to manage/administer Azure resources. Azure CLI is optimized to run automation scripts composed of multiple commands, hence the commands and the overall user experience is not interactive. Azure CLI Shell (az-shell) provides an interactive environment to run Azure CLI 2.0 commands, which is ideal for new users learning the Azure CLI’s capabilities, command structures, and output formats. It provides autocomplete dropdowns, auto-cached suggestions combined with on the fly documentation, including examples of how each command is used. Azure CLI Shell provides an experience that makes it easier to learn and use Azure CLI commands.
