AFTER YEARS OF RESEARCH POSH WAS BORN

CMDLETS• Main building block of PowerShell Scripts

• Common naming convention: Verb then Noun

• e.g.: Get-Help, Get-Object, Remove-Item –Destructive CmdLets have –WhatIf parameter

• Actually .NET Classes that can easily be created if new functionality is required

• The output of one Cmdlet can be piped into further cmdlets using the | operator

• Equality test with expressions such as –eq –lt –le
