Creates a junction, or updates an existing junction if its target is different.


Install-Junction [-Link] <String> [-Target] <String> [-PassThru] [-Force] [-WhatIf] [-Confirm] [<CommonParameters>]


Creates a junction given by -Link which points to the path given by -Target. If Link exists, deletes it and re-creates it if it doesn't point to Target.

Both -Link and -Target parameters accept relative paths for values. Any non-rooted paths are converted to full paths using the current location, i.e. the path returned by Get-Location.

Beginning with Carbon 2.0, returns a System.IO.DirectoryInfo object for the target path, if one is created. Returns a System.IO.DirectoryInfo object for the junction, if it is created and/or updated.
