cd AVA:
$Members = Get-CMDevice -CollectionName "All Servers"
$Members | select Name | Out-File "C:\Scripts\Pending Reboots\All Servers.txt"

Select allOpen in new window

2. I run; C:\Scripts\Pending Reboots\WhiteSpaces.ps1

$content = Get-Content 'C:\Scripts\Pending Reboots\All Servers.txt'
$content | Foreach {$_.TrimEnd()} | Set-Content 'C:\Scripts\Pending Reboots\All Servers.txt'
Get-Content 'C:\Scripts\Pending Reboots\All Servers.txt' | Where-Object {$_ -notmatch 'Name'} | Set-Content 'C:\Scripts\Pending Reboots\All Servers1.txt'
Get-Content 'C:\Scripts\Pending Reboots\All Servers1.txt' | Where-Object {$_ -notmatch '----'} | Set-Content 'C:\Scripts\Pending Reboots\All Servers.txt'
remove-item -path 'C:\Scripts\Pending Reboots\All Servers1.txt' -force

Select allOpen in new window

3. I run this command: . .\Get-PendingReboot.ps1
