What is PowerShell?
PowerShell is a task automation and configuration management framework developed by Microsoft. PowerShell combines a command-line shell with a scripting language built on the .NET framework.

The purpose of PowerShell is to help IT professionals and developers automate administrative tasks, manage system configurations, and perform operations across various environments, including Windows, macOS, and Linux.
PowerShell cmdlets
PowerShell operates through cmdlets which stands for command-lets. Cmdlets are specialized commands that follow a Verb-Noun naming convention (for example: Get-Process, Set-Item). These cmdlets return objects, allowing for powerful data processing and pipeline operations.
PowerShell scripting
PowerShell scripts (files with a .ps1 extension) allow administrators to automate repetitive tasks, such as:
- Managing user accounts in Active Directory or Microsoft 365
- Configuring SharePoint settings and permissions at scale
- Automating software deployment and system updates
- Generating reports on system health and compliance
- Scheduling and executing batch operations
PowerShell is widely used in Microsoft 365 administration, where many advanced governance and security operations can only be performed via PowerShell cmdlets.
