Make functions behave like cmdlets.

[CmdletBinding()] turns a function into an advanced function with common parameters.

You gain -Verbose, -ErrorAction, -PipelineVariable, and SupportsShouldProcess for -WhatIf.

param() with ValueFromPipeline / ValueFromPipelineByPropertyName enables real pipeline binding.

process { } runs per pipeline object; begin/end wrap setup and teardown.

Write-Verbose messages appear only when callers pass -Verbose.

cmdletbinding

function Get-NameUpper { [CmdletBinding()] param([Parameter(ValueFromPipeline)][string]$Name) process { $Name.ToUpper() } }

Match this when you type.
