Using the AWS Tools for Windows PowerShell

This section provides examples of using the AWS Tools for PowerShell to access AWS services. These examples help demonstrate how to use the cmdlets to perform actual AWS tasks.

PowerShell File Concatenation Encoding

Some cmdlets in the Tools for PowerShell edit existing files or records that you have in AWS. An example is Edit-R53ResourceRecordSet, built on the ChangeResourceRecordSets API for Amazon Route 53.

When you edit or concatenate files in PowerShell 5.1 or older releases, PowerShell encodes the output in UTF-16, not UTF-8. This can add unwanted characters and create results that are not valid. A hexadecimal editor can reveal the unwanted characters.

To avoid converting file output to UTF-16, you can pipe your command into PowerShell's Out-File cmdlet, as shown in the following example.

*file concatenation command* | Out-File filename.txt -Encoding utf8

If you are running AWS CLI commands in the PowerShell console, the same behavior applies. You can also pipe an AWS CLI command into Out-File in the PowerShell console. Other cmdlets, such as Export-Csv or Export-Clixml, also have an Encoding parameter. For a complete list of cmdlets that have an Encoding parameter, and that allow you to correct the encoding of the output of a concatenated file, run the following command.

PS> Get-Command -ParameterName "Encoding"

PowerShell 6.0 retains UTF-8 encoding for concatenated file output. Because AWSPowerShell.NetCore requires PowerShell 6.0, you won't experience the encoding change behavior in the Tools for PowerShell Core.

Returned Objects for the Powershell Tools

In some cases, the object returned by an Tools for PowerShell cmdlet does not mirror what is returned from the corresponding API in the AWS SDK for .NET. For example, Get-S3Bucket emits a Buckets collection, not an Amazon S3 response object. Similarly, Get-EC2Instance emits a Reservation collection, not a DescribeEC2Instances result object. This behavior is by design and is intended to have the Tools for PowerShell experience be more consistent with idiomatic PowerShell.

The actual service responses are stored in note properties on the returned objects and are therefore available if you need to access them. For API actions that support NextToken fields, these are also attached as note properties.
