Check if a command has run successfully

Question

I\'ve tried enclosing the following in an if statement so I can execute another command if this succeeds:

Get-WmiObject -Class Win32_Share -ComputerName $Ser         


        

Answer 1

There are instances where any of the options are best suitable. Here is another method:

try {
Add-AzureADGroupMember -ObjectId XXXXXXXXXXXXXXXXXXX -RefObjectId (Get-AzureADUser -ObjectID "XXXXXXXXXXXXXX").ObjectId  -ErrorAction Stop
Write-Host "Added successfully" -ForegroundColor Green
$Count = $Null
$Count = 1
}
catch {
$Count = $Null
$Count = 0
Write-Host "Failed to add: $($error[0])"  -ForegroundColor Red
}

With try and catch, you don't only get the error message returned when it fails, you also have the $count variable assigned the number 0. When the command is successful, your $count value returns 1. At this point, you use this variable value to determine what happens next.
