PowerShell in Cloud Shell will complement Bash to provide another authenticated, browser-based shell experience hosted in Azure that will streamline your Azure admin experience. Like with Bash, PowerShell in Cloud Shell will provide a ready-to-use environment with popular command-line tools and automatic file persistence via Azure File storage, so you'll be able to run your favorite automation scripts from virtually anywhere. Additionally, the PowerShell experience will provide easy navigation of all Azure resources, like filesystem browsing, thereby simplifying discovery and automation across Azure services.
