When not found with Find-VBRViEntity?

[evilaedmin]

Greetings,

What's the best way to detect if Find-VBRViEntity returned no results?

Code: Select all

$Result = Find-VBRViEntity -Name "VMthatdoesnotexit"
if (!$Result) { 
	//Do Some kind of counting here
}

Hi Eugene,

By default, If the entity with the name you specified for Find-VBRViEntity cmdlet doesn't exist, powershell will just resolve an empty line.
If you want to configure some kind of message notifying you on the entity absence, I would suggest to use "throw" keyword in your if statement.
In this case, it will resolve a system-like error with a custom text you wrote.
Example:

Code: Select all

$ViEntityName = "VMDoesnotexist"
$Result = Find-VBRViEntity -Name $ViEntityName
if (!$Result) {
    throw "Entity with the name $ViEntityName is not found"
} 
else {
    $Result
}

All the best,
Oleg
