Work with AWS services in the AWS Tools for 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. These examples rely on cmdlets that the Tools for PowerShell provides. To see what cmdlets are available, see the AWS Tools for PowerShell Cmdlet Reference.
PowerShell File Concatenation Encoding
Some cmdlets in the AWS Tools for PowerShell edit existing files or records that you have in AWS. An example
is Edit-R53ResourceRecordSet
, which calls the ChangeResourceRecordSets API for Amazon RouteĀ 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 and specify UTF-8 encoding, as shown in the following example:
PS >
*some file concatenation command*
| Out-File filename.txt
-Encoding utf8
If you are running AWS CLI commands from within the PowerShell console, the same behavior applies. You
can pipe the output of 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"
Note
PowerShell 6.0 and newer, including PowerShell Core, automatically retains UTF-8 encoding for concatenated file output.
Returned Objects for the PowerShell Tools
To make AWS Tools for PowerShell more useful in a native PowerShell environment, the object returned by a
AWS Tools for PowerShell cmdlet is a .NET object, not the JSON text object that is typically returned from the
corresponding API in the AWS SDK. For example, Get-S3Bucket
emits a Buckets
collection, not an Amazon S3 JSON response object. The Buckets
collection can be placed in the
PowerShell pipeline and interacted with in appropriate ways. Similarly, Get-EC2Instance
emits a Reservation
.NET object collection, not a DescribeEC2Instances
JSON
result object. This behavior is by design and enables the AWS Tools for PowerShell experience to be more consistent
with idiomatic PowerShell.
The actual service responses are available for you if you need them. They are stored as
note
properties on the returned objects. For API actions that support paging by using
NextToken
fields, these are also attached as note
properties.
