powershell pro-Advanced Scripting Engine

Example

function Send-Greeting { [CmdletBinding()] Param([Parameter(Mandatory=$true)][string] $Name) Process { Write-Host ('Hello ' + $Name + '!') } }

Scenario

This function allows creating complex cmdlets with simple scripts, offering capabilities like mandatory parameters and process blocks for iterative actions.

Example

param([Parameter(Mandatory=$true, ValueFromPipelineByPropertyName)][string[]] $ComputerName)

Scenario

Enables the function to accept input directly from the pipeline and ensures that input is validated, making the script robust and error-resistant.

Example

function Test-ErrorHandling { [CmdletBinding()] Param([string] $FilePath) Process { if (-Not (Test-Path $FilePath)) { $PSCmdlet.ThrowTerminatingError((New-Object -TypeName System.Management.Automation.ErrorRecord -ArgumentList ('File not found', 0, [System.Management.Automation.ErrorCategory]::ObjectNotFound, $null))) } else { Get-Content $FilePath } } }

Scenario

Allows scripts to handle errors gracefully and provide detailed feedback to users, similar to fully compiled .NET cmdlets.
