function Find-Item { <# .SYNOPSIS Simple and fast function for finding any item on the filesystem (like find on linux/unix) .DESCRIPTION Function that uses the EnumerateFiles, EnumerateDirectories, EnumerateFileSystemEntries method from the dotnet class System.Io.Directory to quickly find any item on the filesystem Item could be a directory or a file or anything else Class System.IO.EnumerationOptions does not exist in Powershell < 6 (so this function is not supported in the normal PowerShell, only in PowerShell Core/7) .PARAMETER Path Root path to search objects for. Defaults to current working directory .PARAMETER Name Default is '*' = all objects One ore more strings to search for (f.e. '*.exe' OR '*.exe','*.log' OR 'foo*.log') .PARAMETER Type Only search items of specific type: Directory, File or All .PARAMETER Recurse EnumerationOptions property RecurseSubdirectories. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER IgnoreInaccessible EnumerationOptions property IgnoreInaccessible. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER As Could be String or FileInfo. OutputType of found items will be an array of strings or an array of FileSystemInfo Objects. .PARAMETER MatchCasing EnumerationOptions property MatchCasing. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER AttributesToSkip EnumerationOptions property AttributesToSkip. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER MatchType EnumerationOptions property MatchType. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER MaxRecursionDepth EnumerationOptions property MatchType. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER Depth EnumerationOptions property Depth. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .PARAMETER ReturnSpecialDirectories EnumerationOptions property ReturnSpecialDirectories. Check https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 for more information. .EXAMPLE PS C:\> Find-Item -Path c:\windows -Name '*.exe' -As FileInfo Find all items with file format exe in c:\windows without subdirectory and return each file as FileSystemInfo object .EXAMPLE PS C:\> search uses alias search for Find-Item. returns all items (files + directories) with full path in current folder .LINK https://docs.microsoft.com/en-us/dotnet/api/system.io.directoryinfo?view=net-6.0 .LINK https://docs.microsoft.com/en-us/dotnet/api/system.io.enumerationoptions?view=net-6.0 .NOTES Author: Eizedev Last Modified: Jul 13, 2022 Version: 1.1 #> #Requires -PSEdition Core [CmdletBinding()] [OutputType('System.String', 'System.IO.FileSystemInfo')] param ( # Path to search for files [Parameter(Mandatory = $false, Position = 0)] [string] $Path = $pwd, # Name for searching for files [Parameter(Mandatory = $false, Position = 1)] [string[]] $Name = '*', # Type if the items [Parameter(Mandatory = $false)] [ValidateSet('Directory', 'File', 'All')] [string] $Type = 'All', # Include subdirectories if given [Parameter(Mandatory = $false)] [switch] $Recurse, # Sets a value that indicates whether to skip files or directories when access is denied (for example, UnauthorizedAccessException or SecurityException).
