That the object in the variable does not refresh is part of the programing model, only the cmdlets will go to the server API to execute/refresh material.

The question can already be solved using the current cmdlets, there is an idea for a shorthand cmdlet on Add cmdlet Wait-IshPublicationOutput · Issue #72 · RWS/ISHRemote Give that one a thumbs up to help order the backlog. The key problem that the cmdlet would try to solve is to know how often a status-update polling should happen... every 10 seconds will just flood the server if your information architecture already knows it will take 3+ hours or 12+ hours.

However you probably know roughly how long it will take in your environment, for your chosen OutputFormat...

$ishObject = Publish-IshPublicationOutput -LogicalId GUID-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -Version 3 -LanguageCombination en-us -OutputFormat "PDF (XPP A4)" 
# then loop the below code, where sleep is a value that is acceptable for your information architecture ... 
$ishobject = $ishobject | Get-IshPublicationOutput
$ishobject.fishpubstatus_lng_element

I would also reference (+) Publishing APIs help - 01 - General Discussion Forum - Tridion Docs - RWS Community as an interesting read for you.

Thanks Dave, this is all useful.

What does $ishobject = $ishobject do? From looking at the code it seems like it is supposed to update the publish object so you can get a new read on $ishobject.fishpubstatus_lng_element. But I tried it manually a few times and it seems to remain static. As the publshing was happening, the value remained at VPUBSTATUSPUBLISHPENDING and never went to VPUBSTATUSUNPUBLISHING.

Missed this one... the below including the pipe and extra cmdlet says to offer $ishobject as input to Get-IshPublicationOutput which in turn will return a refreshed $ishobject

$ishobject = $ishobject | Get-IshPublicationOutput

An even slightly more optimal way of writing this is

$ishobject = Get-IshPublicationOutput -IshObject $ishobject
