get-hotfix on single server - powershell

Question

first time using powershell and I can't seem to get the below to work - nothing is displayed - I think the script work but I assume I need something to show the results? Any help please:
$hotfix1 = Get-HotFix -Id KB981872
If($hotfix)
{
$Output = "Hotfix is installed you may proceed"
}
else
{
$Output = "Hotfix is not installed"
}
$hotfix1 = Get-HotFix -Id KB981872
Thanks Shay - I have updated it as:
write-host "This will check if Hotfix KB979808 is installed on this Server." -ForegroundColor
Black -BackgroundColor Cyan
write-host "This is required for Windows Server 2008 R2 DFSR Pre-Seeding Robocopying" -
ForegroundColor Black -BackgroundColor Cyan
Write-Host ""
$hotfix1 = Get-HotFix -Id KB979808 -ErrorAction SilentlyContinue
If($hotfix1 -match "KB979808")
{
Write-Host "Hotfix is installed you may proceed" -foregroundcolor "green"
Write-Host ""
}
else
{
Write-Host "Hotfix is NOT installed - Please ensure you install this hotfix BEFORE"
Write-host "copying any data" -foregroundcolor "red"
Write-Host ""
}

The code doesn't output anything because you assign it to a variable. Remove the assignment. You are also assigning the command output to $hotfix1 but checking against $hotfix in the if statement. In addition, if the hot-fix cannot be found you'll get an error, so add the -ErrorAction parameter to suppress the error:
$hotfix1 = Get-HotFix -Id KB981872 -ErrorAction SilentlyContinue
If($hotfix1)
{
"Hotfix is installed you may proceed"
}
else
{
"Hotfix is not installed"
}
$hotfix1
