Detailed Description

The cmdlet manipulates link to a specific item. The target item can be provided as an Item object or through Path/ID. it does not modifies the item itself but rather other items that link to it. If the -RemoveLink parameter is used the link will be removed rather than modified. To deliver more fine grained filtering you can provide ItemLink using the -Link parameter. You can obtain ItemLinks using Get-ItemReferrer or Get-ItemReference cmdlets. Consult Examples for specific use cases of each approach.

EXAMPLE 1

This example covers global operations

Assuming Sitecore PowerShell Extensions 4.2 or newer is installed Assuming your Home has an "Image" field of type "Image" Assuming you have second item next to Home called Home2 that has an "Image" field of type "Image"


$coverImage = Get-Item 'master:\media library\Default Website\cover'
$scLogoImage = Get-item 'master:\media library\Default Website\sc_logo'

Write-Host "`nReset 'home', 'child' and 'home2' to link to 'cover'- 3 items" -Foreground Magenta
(Get-item master:\content\home).Image = $coverImage
(Get-item master:\content\Home\child).Image = $coverImage

Get-ItemReferrer -Item $coverImage            

Write-Host "`nRelinking all instances of 'cover' image to  'sc_logo'" -Foreground Yellow
