Will Powershell work as command line?

There are several script examples out there.

See if this works for you.  I just tested it and it appears OK to me.

#Based on <>
function Test-PendingReboot
 if (Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\RebootPending" -EA Ignore) { return $true }
 if (Get-Item "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired" -EA Ignore) { return $true }
 if (Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager" -Name PendingFileRenameOperations -EA Ignore) { return $true }
 try { 
   $util = [wmiclass]"\\.\root\ccm\clientsdk:CCM_ClientUtilities"
   $status = $util.DetermineIfRebootPending()
   if(($status -ne $null) -and $status.RebootPending){
     return $true
 return $false

Open in new window

Paste that code into a powershell window then from the same prompt:  Test-PendingReboot

So this has to be done with a PowerShell script it can't be done with a single PowerShell or command line command?

I had to Google for it and since I ended up with the same link, I'm guessing Sarang did as well.

I couldn't find anything simpler than the one I posted.  Maybe someone else will have other ideas.
