Example 2: This example lists all patch baselines provided by Amazon. The syntax used by this example requires PowerShell version 3 or later.

$filter1 = @{Key="OWNER";Values=@("AWS")}

Example 4: With PowerShell version 2, you must use New-Object to create each tag.

$filter1 = New-Object Amazon.SimpleSystemsManagement.Model.PatchOrchestratorFilter
$filter1.Key = "OWNER"
$filter1.Values = "AWS"

Get-SSMPatchBaseline -Filter $filter1

Output:
