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.
The Join-Path 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
| Copy Code |
|
|---|---|
C:\PS>join-path -path c:\win* -childpath System* Description ----------- 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
| Copy Code |
|
|---|---|
C:\PS>join-path c:\win* System* -resolve Description ----------- 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
| Copy Code |
|
|---|---|
C:\PS>PS HKLM:\> join-path System *ControlSet* -resolve Description ----------- This command displays the registry keys in the HKLM\System registry subkey that include "ControlSet". This example shows how to use Join-Path with the Windows PowerShell registry provider. |
|
Example 4
| Copy Code |
|
|---|---|
C:\PS>join-path -path C:, D:, E:, F: -childpath New Description ----------- This command uses Join-Path to combine multiple path roots with a child path. |
|
Example 5
| Copy Code |
|
|---|---|
C:\PS>get-psdrive -psprovider filesystem | foreach {$_.root} | join-path -childpath Subdir
Description
-----------
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 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.
