<# .SYNOPSIS Test multiple paths .DESCRIPTION Easy way to test multiple paths for public functions and have the same error handling .PARAMETER Path Array of paths you want to test They have to be the same type, either file/leaf or folder/container .PARAMETER Type Type of path you want to test Valid options are: "Leaf" "Container" .PARAMETER Create Switch to instruct the cmdlet to create the folder .EXAMPLE PS C:\> Test-PathExists "c:\temp","c:\temp\dir" -Type Container This will test if the mentioned paths (folders) exists and the current context has enough permission. .NOTES Author: Mötz Jensen (@splaxi) #> function Test-PathExists { [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseSingularNouns", "")] [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseShouldProcessForStateChangingFunctions", "")] [CmdletBinding()] [OutputType([System.Boolean])] param ( [Parameter(Mandatory = $True, Position = 1 )] [string[]] $Path, [ValidateSet('Leaf', 'Container')] [Parameter(Mandatory = $True, Position = 2 )] [string] $Type, [switch] $Create ) $res = $false $arrList = New-Object -TypeName "System.Collections.ArrayList" foreach ($item in $Path) { Write-PSFMessage -Level Verbose -Message "Testing the path: $item" -Target $item $temp = Test-Path -Path $item -Type $Type if ((!$temp) -and ($Create) -and ($Type -eq "Container")) { Write-PSFMessage -Level Verbose -Message "Creating the path: $item" -Target $item New-Item -Path $item -ItemType Directory -Force -ErrorAction Stop $temp = $true } elseif (!$temp) { Write-PSFMessage -Level Host -Message "The <c='em'>$item</c> path wasn't found.
