why my powershell try catch codes are printing only error?

$MDservices = ""

$tempservices = ""

try{

$alerter = Get-Service Alerter

if($alerter.Status -eq 'Running'){

    $alerter = Out-String -InputObject $alerter.DisplayName

    $MDservices = $tempservices + $alerter

} else {

    continue

}

}

catch {

 write "somethings wrong"

}

This is my powershell try catch codes. I expect this output is write "somethings wrong" becaues my pc dosen't have 'Alerter' service but it's output is printing error

What am i do guys? Help me:(

Most likely due your default $ErrorActionPreference value.

Try following :

try
{   $alerter = Get-Service Alerter -ErrorAction Stop
    if($alerter.Status -eq 'Running') {
        $alerter = Out-String -InputObject $alerter.DisplayName
        $MDservices = $tempservices + $alerter
    }
    else {
        continue
    }
}
catch
{   Write-Host "somethings wrong"
}
finally
{
    Write-Host "cleaning up ..."
}

If the try block does not generate a terminating error, it will not move into the Catch block. This is controlled by -ErrorAction parameter. By default it uses Continue. So just change

# This will generate terminating error and move to Catch Block.
$alerter = Get-Service Alerter -ErrorAction Stop
