aws ec2 describe-instance-status \
    --instance-ids i-1234567890abcdef0

輸出：

{
    "InstanceStatuses": [
        {
            "InstanceId": "i-1234567890abcdef0",
            "InstanceState": {
                "Code": 16,
                "Name": "running"

            },
            "InstanceStatus": {
                "Status": "ok",
                "Details": [

$status = Get-EC2InstanceStatus -InstanceId i-12345678
$status.InstanceState
