名前 Get-ChildItem 概要 Gets the items and child items in one or more specified locations. 構文 Get-ChildItem [[-Path] ] [[-Filter] ] [-Exclude ] [-Force] [-Include ] [-Nam e] [-Recurse] [-UseTransaction []] [] Get-ChildItem [[-Filter] ] [-Exclude ] [-Force] [-Include ] [-Name] [-Recurse] -Litera lPath [-UseTransaction []] [] 説明 The Get-ChildItem cmdlet gets the items in one or more specified locations. If the item is a container, it gets th e items inside the container, known as child items. You can use the Recurse parameter to get items in all child co ntainers. A location can be a file system location, such as a directory, or a location exposed by a different Windows PowerS hell provider, such as a registry hive or a certificate store. パラメーター -Exclude Specifies, as a string array, an item or items that this cmdlet excludes in the operation. The value of this p arameter qualifies the Path parameter. Enter a path element or pattern, such as *.txt. Wildcards are permitted . 必須 false 位置 named 既定値 パイプライン入力を許可する false ワイルドカード文字を許可する true -Filter Specifies a filter in the provider's format or language. The value of this parameter qualifies the Path parame ter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more effic ient than other parameters, because the provider applies them when retrieving the objects, rather than having Windows PowerShell filter the objects after they are retrieved. 必須 false 位置 2 既定値 パイプライン入力を許可する false ワイルドカード文字を許可する true -Force [] Forces the command to run without asking for user confirmation. 必須 false 位置 named 既定値 False パイプライン入力を許可する false ワイルドカード文字を許可する false -Include Specifies, as a string array, an item or items that this cmdlet includes in the operation. The value of this p arameter qualifies the Path parameter. Enter a path element or pattern, such as *.txt. Wildcards are permitted . The Include parameter is effective only when the command includes the Recurse parameter or the path leads to t he contents of a directory, such as C:\Windows\*, where the wildcard character specifies the contents of the C :\Windows directory. 必須 false 位置 named 既定値 パイプライン入力を許可する false ワイルドカード文字を許可する true -LiteralPath Specifies, as a string arrya, a path to one or more locations. Unlike the Path parameter, the value of the Lit eralPath parameter is used exactly as it is typed. No characters are interpreted as wildcards. If the path inc ludes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences. 必須 true 位置 named 既定値 パイプライン入力を許可する true (ByValue, ByPropertyName) ワイルドカード文字を許可する false -Name [] Indicates that this cmdlet gets only the names of the items in the locations. If you pipe the output of this c ommand to another command, only the item names are sent. 必須 false 位置 named 既定値 パイプライン入力を許可する false ワイルドカード文字を許可する false -Path Specifies a path to one or more locations. Wildcards are permitted. The default location is the current direct ory (.). 必須 false 位置 1 既定値 Current directory パイプライン入力を許可する true (ByValue, ByPropertyName) ワイルドカード文字を許可する true -Recurse [] Indicates that this cmdlet gets the items in the specified locations and in all child items of the locations. In Windows PowerShell 2.0 and earlier versions of Windows PowerShell, the Recurse parameter works only when th e value of the Path parameter is a container that has child items, such as C:\Windows or C:\Windows\*, and not when it is an item does not have child items, such as C:\Windows\*.exe. 必須 false 位置 named 既定値 False パイプライン入力を許可する false ワイルドカード文字を許可する false -UseTransaction [] Includes the command in the active transaction. This parameter is valid only when a transaction is in progress . For more information, seeIncludes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see 必須 false 位置 named 既定値 false パイプライン入力を許可する false ワイルドカード文字を許可する false このコマンドレットは、次の共通パラメーターをサポートします: Verbose、 Debug、ErrorAction、ErrorVariable、WarningAction、WarningVariable、 OutBuffer, PipelineVariable、および OutVariable。詳細については、 about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216) を参照してください。 入力 System.String You can pipe a string that contains a path to this cmdlet. 出力 System.Object The type of object that this cmdlet returns is determined by the objects in the provider drive path. System.String If you use the Name parameter, Get-ChildItem returns the object names as strings. メモ You can also refer to Get-ChildItem by its built-in aliases, ls, dir, and gci. For more information, see about _Aliases. This cmdlet does not get hidden items by default. To get hidden items, use the Force parameter. The Get-ChildItem cmdlet is designed to work with the data exposed by any provider. To list the providers avai lable in your session, type Get-PSProvider. For more information, see about_Providers (http://go.microsoft.com /fwlink/?LinkID=113250). Example 1: Get child items in the current directory PS C:\>Get-ChildItem This command gets the child items in the current location. If the location is a file system directory, it gets the files and sub-directories in the current directory. If the item does not have child items, this command returns t o the command prompt without displaying anything. The default display lists the mode (attributes), last write time, file size (length), and the name of the file. Th e valid values for mode are d (directory), a (archive), r (read-only), h (hidden), and s (system). Example 2: Get all files with the specified file extension in the current directory and subdirectories PS C:\>Get-ChildItem Path "*.txt" -Recurse -Force This command gets all of the .txt files in the current directory and its subdirectories. The Recurse parameter dir ects Windows PowerShell to get objects recursively, and it indicates that the subject of the command is the specif ied directory and its contents. The Force parameter adds hidden files to the display. To use the Recurse parameter on Windows PowerShell 2.0 and earlier versions of Windows PowerShell, the Path parame ter must be a container. Use the Include parameter to specify the .txt file type. For instance, Get-ChildItem Pat h .\* -Include *.txt -Recurse Example 3: Get all child items using an inclusion and exclusion PS C:\>Get-ChildItem Path "C:\Windows\Logs\*" -Include "*.txt" -Exclude "A*" This command lists the .txt files in the Logs subdirectory, except for those whose names start with the letter A. It uses the wildcard character (*) to indicate the contents of the Logs subdirectory, not the directory container. Because the command does not include the Recurse parameter, the command does not include the content of directory automatically; you need to specify it. Example 4: Get all registry keys in a specific key PS C:\>Get-ChildItem Path "HKLM:\Software" This command gets all of the registry keys in the HKEY_LOCAL_MACHINE\SOFTWARE key in the registry of the local com puter. Example 5: Get the name of items in the current directory PS C:\>Get-ChildItem -Name This command gets only the names of items in the current directory. Example 6: Get all certificates in a certification drive that have code-signing authority PS C:\>Import-Module Microsoft.PowerShell.Security PS C:\>Get-ChildItem Path "Cert:\*" -Recurse -CodeSigningCert This command gets all of the certificates in the Windows PowerShell Cert: drive that have code-signing authority. The first command imports the Microsoft.PowerShell.Security module into the session. This module includes the Cert ificate provider that creates the Cert: drive. The second command uses the Get-ChildItem cmdlet. The value of the Path parameter is the Cert: drive. The Recurse parameter requests a recursive search. The CodeSigningCertificate parameter is a dynamic parameter that the Certif icate provider adds to the Get-ChildItem cmdlet. This parameter gets only certificates that have code-signing auth ority. For more information about the Certificate provider and the Cert: drive, go to http://go.microsoft.com/fwlink/?Lin kID=113433 or use the Update-Help cmdlet to download the help files for the Microsoft.PowerShell.Security module a nd then type Get-Help Certificate. Example 7: Get all items in the specified directory and its subdirectories that have an inclusion and exclusion PS C:\>Get-ChildItem Path C:\Windows Include "*mouse*" -Exclude "*.png" This command gets all of the items in the C:\Windows directory and its subdirectories that have mouse in the file name, except for those with a .png file name extension. 関連するリンク Online Version: http://go.microsoft.com/fwlink/p/?linkid=290488 Get-Item Get-Location Get-Process Get-PSProvider
