PowerShell
PowerShell is a cross-platform task automation and configuration management framework from Microsoft, consisting of a command-line shell and scripting language. It is built on the .NET Common Language Runtime (CLR) and integrates with Windows, Linux, and macOS systems to automate administrative tasks, manage cloud resources, and handle system configurations. PowerShell uses cmdlets (pronounced 'command-lets') as its primary command type, which are lightweight, single-function commands that can be combined in pipelines for complex operations.
Developers should learn PowerShell for automating repetitive tasks, managing cloud infrastructure (especially in Azure), and scripting system administration on Windows, Linux, or macOS environments. It is particularly valuable for DevOps roles, IT professionals, and developers working with Microsoft technologies, as it provides deep integration with Windows systems, Active Directory, and Azure services, enabling efficient automation of deployments, monitoring, and resource management.
