In Carbon 2.1.1 and earlier, the `Path` paramater does not support wildcard characters, nor can it delete junctions that contained wildcards. Carbon 2.2.0 added support for wildcards in the `Path` parameter. If using wildcards, if the wildcard pattern doesn't match any junctions, nothing is removed and you'll get no errors. If the `Path` parameter does not contain wildcards, `Path` must exist and must be a path to a junction. Carbon 2.2.0 also added the `LiteralPath` parameter. Use it to delete junctions whose path contains wildcard characters. .LINK Install-CJunction .LINK New-CJunction .LINK Test-CPathIsJunction .LINK Uninstall-CJunction .EXAMPLE Remove-CJunction -Path 'C:\I\Am\A\Junction' Removes the `C:\I\Am\A\Junction` path. .EXAMPLE Remove-CJunction -path 'C:\Temp\*' Demonstrates how to use wildcards to delete multiple junctions in a directory. Nothing happens if the wildcard doesn't match any junctions. .EXAMPLE Remove-CJunction -LiteralPath 'C:\Temp\ContainsWildcards[]' Demonstrates how to use the `Literalpath` parameter to delete a junction that contains wildcard characters. #> [CmdletBinding(SupportsShouldProcess=$true,DefaultParameterSetName='Path')] param( [Parameter(Mandatory=$true,Position=0,ParameterSetName='Path')] [string] # The path to the junction to remove. # # Wildcards are supported in Carbon 2.2.0 and later. $Path, [Parameter(Mandatory=$true,ParameterSetName='LiteralPath')] [string] # The literal path to the junction to remove.
