[<CommonParameters>] 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-AzStorageBlobContentThis 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" -ForceThis 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 credentail, then download blob with both Sas Uri and bearer token.
Parameters
-AbsoluteUri
Blob uri to download from.

| Aliases: | Uri, BlobUri |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-AsJob
Run cmdlet in the background.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Blob
Specifies the name of the blob to be downloaded.
| Type: | String |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-BlobBaseClient
BlobBaseClient Object
| Type: | BlobBaseClient |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-CheckMd5
Specifies whether to check the Md5 sum for the downloaded file.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ClientTimeoutPerRequest
Specifies the client-side time-out interval, in seconds, for one service request. If the previous call fails in the specified interval, this cmdlet retries the request. If this cmdlet does not receive a successful response before the interval elapses, this cmdlet returns an error.
| Type: | Nullable<T>[Int32] |
| Aliases: | ClientTimeoutPerRequestInSeconds |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-CloudBlob
Specifies a cloud blob. To obtain a CloudBlob object, use the Get-AzStorageBlob cmdlet.
| Type: | CloudBlob |
| Aliases: | ICloudBlob |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-CloudBlobContainer
Specifies a CloudBlobContainer object from the Azure storage client library. You can create it or use the Get-AzStorageContainer cmdlet.
| Type: | CloudBlobContainer |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-ConcurrentTaskCount
Specifies the maximum concurrent network calls. You can use this parameter to limit the concurrency to throttle local CPU and bandwidth usage by specifying the maximum number of concurrent network calls. The specified value is an absolute count and is not multiplied by the core count. This parameter can help reduce network connection problems in low bandwidth environments, such as 100 kilobits per second. The default value is 10.
