In Sitecore powershell, can you make an item unpublishable

Question

In Sitecore Powershell for Sitecore 7.2...

Is it possible to set the "Publishable" rights on given items (to make them unpublishable)?

Specifically, I wish to automate the process of: selecting an item, opening Publish > Restrictions > Change, clicking the Item tab, and unchecking the "Publishable" box.

I've tried find that property of an item with no luck. I thought this might work, but "__Publishable" is not correct:

(get-item -Path master:/sitecore/content/Path/Home/About-Us)."__Publishable"

Is there a way to make Powershell report ALL of the properties of an item?

Answer 1

The field for making an item un-publishable is:

__Never publish

So you could do this:

(get-item -Path master:/sitecore/content/DIAGlobal/Home/About-Us)."__Never publish"

Or if you wanted to edit it similar to back end code you could do:

$item = Get-Item master:/sitecore/content/DIAGlobal/Home/About-Us
$item.Editing.BeginEdit()
$item["__Never publish"] = "1"
$item.Editing.EndEdit()
