Powershell script not working right with "pause" in the end

I have a strange problem with my script, which runs on two different servers, on one server it's working perfectly and on the other one it's behave very strange.

Here is the code:

write-host "Cheking if App open please wait"

write-host "`n"

$open = Get-SmbOpenFile | 
          Where-Object {$_.Path -eq "d:\Shares\Share1\app.exe"} |
            Select-Object @{l="Who is using App?";e="ClientUserName"}, Path

if ($open) {
 write-host "Showing open files:"
  $open

}

else {
  write-host "all closed"
}

pause

On a server 2012 r2 with powershell version 3.0 it's working perfectly, and on the second server which is 2016 it's not working.

So I've started to investigate and I came to a conclusion that if I remove the "pause" in the end of the script on the 2016 server it's working perfectly, which is very strange..

With the "pause" in the end, I'am getting this result:

Showing open files:

Press Enter to continue...:

Thanks a lot for your help :)

Solution

Format-table (implied) waits indefinitely for 2 objects.

Hmm, format-table never comes out before the pause.

[pscustomobject]@{name='joe'}; pause

Press Enter to continue...:
name
----
joe

With format-list, it comes out right away:

[pscustomobject]@{name='joe'}|format-list; pause

name : joe


Press Enter to continue...:

This should work:

write-host "Cheking if App open please wait"

write-host "`n"

$open = Get-SmbOpenFile | 
          Where-Object {$_.Path -eq "d:\Shares\Share1\app.exe"} |
            Select-Object @{l="Who is using App?";e="ClientUserName"}, Path

if ($open) {
 write-host "Showing open files:"
  $open | format-list

}

else {
  write-host "all closed"
}

pause
