get-ec2instance does not show platformdetails info

Hello, The "Get-EC2Instance" cmdlet calls the DescribeInstances API operation[1].

According to the documentation for the DescribeInstances API:
"The value is Windows for Windows instances; otherwise blank."[2]

[1] https://docs.aws.amazon.com/powershell/latest/reference/
[2] https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instances.html

Is there anyway to get platform details for linux using powershell?

I would suggest installing the AWS CLI for Windows[1]. The referenced page provides instructions for installation in Windows.

You could then use the following command:

aws ec2 describe-instances | Select-String "InstanceId","PlatformDetails"

While the Get-EC2Instance only returns a "Platform" parameter, which is blank for non-Windows instances, the "describe-instances" CLI command provides a "PlatformDetails" parameter which will indicate "Linux/UNIX" for instances running a Linux OS.
