What is PowerShell?

PowerShell is an open source command-line shell and scripting language created by Microsoft and usable on Windows, macOS, and Linux. This tool allows you to use functions like cmdlets to quickly execute specific tasks within the framework of the system. PowerShell is used mainly for task automation and configuration management, particularly for administrative tasks otherwise considered tedious or repetitive. For example, PowerShell can be used to check whether each server in a group is running a particular program, which is essential for situations like verifying that security systems are functioning as intended. Despite its capabilities, PowerShell is rarely used outside of corporate and administrative environments.
