function Get-Object { <# .SYNOPSIS Get objects .DESCRIPTION Get list of objects matching specifications (wrapper for Get-ChildItem with checks) .PARAMETER Path [String] The path parameter corresponds to the path to the directory or object to retrieve. .PARAMETER Type [String] The type parameters corresponds to the type of object(s) to retrieve. Three values are possible: - ALL : files and folders alike - File: only files - Folder: only folders .PARAMETER Filter [String] The filter parameters corresponds to the pattern to match to filter objects from the result set. .PARAMETER Exclude [String] The exclude parameters corresponds to the pattern to match to exclude ob- jects from the result set. .OUTPUTS [System.Collections.ArrayList] Get-Object returns an array list containing the list of objects. .EXAMPLE Get-Object -Path "\path\to\folder" In this example, Get-Object will return the object "folder". .EXAMPLE Get-Object -Path "\path\to\folder" -ChildItem In this example, Get-Object will return all the objects (files and folders) listed in the "\path\to\folder" directory. .EXAMPLE Get-Object -Path "\path\to\folder" -Type "File" -ChildItem In this example, Get-Object will return all the files listed in the "\path\to\folder" directory. .EXAMPLE Get-Object -Path "\path\to\folder" -Type "Folder" -ChildItem In this example, Get-Object will return all the folders listed in the "\path\to\folder" directory. .EXAMPLE Get-Object -Path "\path\to\folder" -Type "File" -Filter "*.txt" -ChildItem In this example, Get-Object will return all the text files listed in the "\path\to\folder" directory. .EXAMPLE Get-Object -Path "\path\to\folder" -Type "File" -Exclude "*.txt" -ChildItem In this example, Get-Object will return all the non-text files listed in the "\path\to\folder" directory. /!\ The use of the exclude tag require PowerShell Core v6.1 or later. .NOTES File name: Get-Object.ps1 Author: Florian Carrier Creation date: 2019-06-14 Last modified: 2022-04-19 #> [CmdletBinding ()] Param ( [Parameter ( Position = 1, Mandatory = $true, HelpMessage = "Path to the items" )] [ValidateNotNullOrEmpty ()] [System.String] $Path, [Parameter ( Position = 2, Mandatory = $false, HelpMessage = "Type of item" )] [ValidateSet ( "All", "File", "Folder" )] [System.String] $Type = "All", [Parameter ( Position = 3, Mandatory = $false, HelpMessage = "Filter to apply" )] [ValidateNotNullOrEmpty ()] [System.String] $Filter = "*", [Parameter ( Position = 4, Mandatory = $false, HelpMessage = "Pattern to exclude" )] [ValidateNotNullOrEmpty ()] [System.String[]] $Exclude = $null, [Parameter ( HelpMessage = "Recursive search" )] [Switch] $Recurse, [Parameter ( HelpMessage = "Retrieve child items" )] [Switch] $ChildItem, [Parameter ( HelpMessage = "Suppresses console hints" )] [Switch] $Silent, [Parameter ( HelpMessage = "Stop script if no results are found" )] [Switch] $StopScript ) Begin { # Get global preference vrariables Get-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState # Check path $Path = Resolve-Path -Path $Path if (Test-Object -Path $Path -NotFound) { Write-Log -Type "ERROR" -Message "Path not found $Path" -ErrorCode 1 } $ObjectType = [Ordered]@{ "All" = "items" "File" = "files" "Folder" = "folders" } } Process { if ($ChildItem -eq $true) { $Objects = New-Object -TypeName "System.Collections.ArrayList" # Check PowerShell version to prevent issue https://github.com/PowerShell/PowerShell/issues/6865 $PSVersion = $PSVersionTable.PSVersion | Select-Object -ExpandProperty "Major" if ($PSVersion -lt 6) { switch ($Type) { "File" { $Objects = @(Get-ChildItem -Path $Path -Filter $Filter -Recurse:$Recurse -File) } "Folder" { $Objects = @(Get-ChildItem -Path $Path -Filter $Filter -Recurse:$Recurse -Directory) } default { $Objects = @(Get-ChildItem -Path $Path -Filter $Filter -Recurse:$Recurse) } } # Workaround to exclude items if ($null -ne $Exclude) { $Objects = $Objects | Where-Object -Property "Name" -NotMatch -Value ((ConvertTo-RegularExpression -String $Exclude) -join "|") } } else { switch ($Type) { "File" { $Objects = @(Get-ChildItem -Path $Path -Filter $Filter -Exclude $Exclude -Recurse:$Recurse -File) } "Folder" { $Objects = @(Get-ChildItem -Path $Path -Filter $Filter -Exclude $Exclude -Recurse:$Recurse -Directory) } default { $Objects = @(Get-ChildItem -Path $Path -Filter $Filter -Exclude $Exclude -Recurse:$Recurse) } } } # Check results if ($Objects.Count -eq 0) { if ($Silent -eq $false) { # Print hints if ($Filter -ne "*") { Write-Log -Type "ERROR" -Message "No $($ObjectType.$Type) were found in $Path matching the filter ""$Filter""." } elseif ($Exclude) { Write-Log -Type "ERROR" -Message "No $($ObjectType.$Type) corresponding to the criterias were found in $Path." } else { Write-Log -Type "ERROR" -Message "No $($ObjectType.$Type) were found in $Path." } } if ($PSBoundParameters.ContainsKey("StopScript")) { Stop-Script -ExitCode 1 } else { return $null } } else { return $Objects } } else { # Return item Get-Item -Path $Path } } } |
