SYNTAX

Join-Path [-Path] <String[]> [-ChildPath] <String> [-Credential <PSCredential>] [-Resolve] [-UseTransaction] [<CommonParameters>]





DESCRIPTION

The Join-Path cmdlet combines a path and child-path into a single path. The provider supplies the path delimiters.





PARAMETERS

-ChildPath <String>

Specifies the elements to append to the value of the Path parameter. Wildcards are permitted. The ChildPath parameter is required, although

the parameter name ("ChildPath") is optional.

-Credential <PSCredential>

Specifies a user account that has permission to perform this action. The default is the current user.



Type a user name, such as User01 or Domain01\\User01. Or, enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If

you type a user name, you will be prompted for a password.



This parameter is not supported by any providers installed with Windows PowerShell.



Required? false

Position? named

Default value None

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-Path <String[]>

Specifies the main path (or paths) to which the child-path is appended. Wildcards are permitted.



The value of Path determines which provider joins the paths and adds the path delimiters. The Path parameter is required, although the

parameter name ("Path") is optional.



Required? true

INPUTS

System.String

You can pipe a string that contains a path to this cmdlet.





OUTPUTS

System.String

This cmdlet returns a string that contains the resulting path.





NOTES





* The cmdlets that contain the Path noun (the Path cmdlets) manipulate path names and return the names in a concise format that all Windows

PowerShell providers can interpret. They are designed for use in programs and scripts where you want to display all or part of a path name in

a particular format. Use them like you would use Dirname, Normpath, Realpath, Join, or other path manipulators.



You can use the path cmdlets with several providers, including the FileSystem, Registry, and Certificate providers.



This cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type `Get-PSProvider`.

For more information, see about_Providers.

Example 1: Combine a path with a child path



PS C:\\>Join-Path -Path "C:\\win*" -ChildPath "System*"



This command uses Join-Path to combine the C:\\Win path with the System child path. The Windows PowerShell file system provider, FileSystem joins

the path and adds the "\\" delimiter.

Example 2: Display files and folders by joining a path with a child path



PS C:\\>Join-Path "C:\\win*" "System*" -Resolve



This command displays the files and folders that are referenced by joining the C:\\Win path and the System child path. It displays the same files

and folders as Get-ChildItem, but it displays the fully qualified path to each item. In this command, the Path and ChildPath optional parameter

names are omitted.

Example 3: Use Join-Path with the Windows PowerShell registry provider



PS C:\\>

PS HKLM:\\> Join-Path System *ControlSet* -Resolve



This command displays the registry keys in the HKLM\\System registry subkey that include ControlSet. The command shows how to use Join-Path with

the Windows PowerShell registry provider.

Example 4: Combine multiple path roots with a child path



PS C:\\>Join-Path -Path C:, D:, E:, F: -ChildPath New



This command uses Join-Path to combine multiple path roots with a child path.

Example 5: Combine the roots of a file system drive with a child path



PS C:\\>Get-PSDrive -PSProvider filesystem | ForEach {$_.root} | Join-Path -ChildPath "Subdir"



This command combines the roots of each Windows PowerShell file system drive in the console with the Subdir child path.



The command uses the Get-PSDrive cmdlet to get the Windows PowerShell drives supported by the FileSystem provider. The ForEach-Object statement

selects only the Root property of the PSDriveInfo objects and combines it with the specified child path.



The output shows that the Windows PowerShell drives on the computer included a drive mapped to the C:\\Program Files directory.
