Description

The Get-AzStorageBlobContent cmdlet downloads the specified storage blob. If the blob name is not valid for the local computer, this cmdlet automatically resolves it if it is possible.

Examples

Example 1: Download blob content by name

Get-AzStorageBlobContent -Container "ContainerName" -Blob "Blob" -Destination "C:\test\"

This command downloads a blob by name.

Example 2: Download blob content using the pipeline

Get-AzStorageBlob -Container containername -Blob blobname | Get-AzStorageBlobContent

This command uses the pipeline to find and download blob content.

Example 3: Download blob content using the pipeline and a wildcard character

Get-AzStorageContainer container* | Get-AzStorageBlobContent -Blob "cbox.exe" -Destination "C:\test"

This example uses the asterisk wildcard character and the pipeline to find and download blob content.

Example 4: Get a blob object and save it in a variable, then download blob content with the blob object

$blob = Get-AzStorageBlob -Container containername -Blob blobname
Get-AzStorageBlobContent -CloudBlob $blob.ICloudBlob -Destination "C:\test"

This example first get a blob object and save it in a variable, then download blob content with the blob object.

Example 5: Download a blob content with blob Uri

Get-AzStorageBlobContent -Uri $blobUri -Destination "C:\test" -Force

This example will download a blob content with Uri, the Uri can be a Uri with Sas token. If the blob is on a managed disk account, and server requires a bearer token besides Sas Uri to download, the cmdlet will try to generate a bearer token with server returned audience and the login AAD user credential, then download blob with both Sas Uri and bearer token.
