PowerShell is a powerful scripting language, written by Microsoft. It uses the .NET Common Language Runtime (CLR) which provides massive functionality out of the box and is also entirely extensible. It is designed for automating and managing systems and is often used for the automation or maintenance of cloud environments, such as Azure and AWS. It is also the language of choice for managing platforms such as Microsoft Exchange and, of course, SQL Server. PowerShell Core Edition (v7) is supported not only on Windows but also on Mac OS and Linux. There is full support for many variants of Linux, including Red Hat, Ubuntu, and Debian, to name but a few.
