How to download files from s3 service to local folder
Since this question is one of the top Google results for "powershell download s3 files" I'm going to answer the question in the title (even though the actual question text is different):
Read-S3Object -BucketName "my-s3-bucket" -KeyPrefix "path/to/directory" -Folder .You might need to call Set-AWSCredentials if it's not a public bucket.
Similar to Will's example, if you want to download the whole content of a "folder" keeping the directory structure try:
Get-S3Object -BucketName "my-bucket" -KeyPrefix "path/to/directory" | Read-S3Object -Folder .MS doc at https://docs.aws.amazon.com/powershell/latest/reference/items/Read-S3Object.html provides examples with fancier filtering.
If you have installed the AWS PowerShell Module, you haven't correctly loaded it into your current session. We're identifying this as the issue because the error you specified means that the given cmdlet can't be found.
Verify first that the module is installed, by any of the options below:
Load module into an existing session: (PowerShell v3 and v4):
From the documentation:
In PowerShell 4.0 and later releases, Import-Module also searches the Program Files folder for installed modules, so it is not necessary to provide the full path to the module. You can run the following command to import the AWSPowerShell module. In PowerShell 3.0 and later, running a cmdlet in the module also automatically imports a module into your session.
To verify correct installation, add the following command to the beginning of your script:
PS C:\> Import-Module AWSPowerShellLoad module into an existing session: (PowerShell v2):
To verify correct installation, add the following command to the beginning of your script:
PS C:\> Import-Module "C:\Program Files (x86)\AWS Tools\PowerShell\AWSPowerShell\AWSPowerShell.psd1"Open a new session with Windows PowerShell for AWS Desktop Shortcut:
A shortcut is added to your desktop that starts PowerShell with the correct module loaded into the session. If your installation was successful, this shortcut should be present and should also correctly load the AWS PowerShell module without additional effort from you.
From the documentation:
The installer creates a Start Menu group called, Amazon Web Services, which contains a shortcut called Windows PowerShell for AWS. For PowerShell 2.0, this shortcut automatically imports the AWSPowerShell module and then runs the Initialize-AWSDefaults cmdlet. For PowerShell 3.0, the AWSPowerShell module is loaded automatically whenever you run an AWS cmdlet. So, for PowerShell 3.0, the shortcut created by the installer only runs the Initialize-AWSDefaults cmdlet. For more information about Initialize-AWSDefaults, see Using AWS Credentials.
