Script to download files from Azure Storage account which specified in csv file

Question

Hi team,

Newbie in scripting here. We have a storage account where we store nearly thousand files. Each week I have a list of files which I need to download in order to complete some manual workaround from this storage account.

The list of files is getting bigger, nearly 300 files now. Is there a way to write a script using Azure CLI to download specific list of files.

Thank for help

Hi @Abduazim Sobitov

You can use the script suggested on Stack Overflow (answer by John Bull):

Download a list of specific files from Azure Blob

https://stackoverflow.com/questions/69408837/download-a-list-of-specific-files-from-azure-blob

$accountName = "account-name"  
$accountKey = "account-key"  
$containerName = "container-name"  
$context = New-AzStorageContext -StorageAccountName $accountName -StorageAccountKey $accountKey  
$destination = "C:\temp"  
  
$blobNames = Get-Content $destination\list.txt  
  
For ($i=0; $i -lt $blobNames.Length; $i++) {  
    $blob = $blobNames[$i]  
    Write-Host "Downloading $blob. Please wait."  
    Get-AzStorageBlobContent -Blob $blob -Container $containerName -Destination $destination -Context $context -Verbose  
}  

It'll work like a charm, given that the text file that holds a list of file names for the blobs you need to download is located in the '$destination' directory (could be any directory on your PC, though). p.s., the files just need to be listed as one column (separated by a caret return, i.e., "\n" at the end of each file name). Thanks @Anonymous Mantri for the solution.

Documentation for Get-AzStorageBlobContent

https://learn.microsoft.com/en-us/powershell/module/az.storage/get-azstorageblobcontent?view=azps-8.2.0

You will also need to ensure you have the Az Module (Install the Azure Az PowerShell module)
