You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_storage_blob_copy_start batch'.The syntax is: az storage blob copy start-batch [--account-key]
                                 [--account-name]
                                 [--auth-mode {key, login}]
                                 [--connection-string]
                                 [--destination-container]
                                 [--destination-path]
                                 [--dryrun]
                                 [--pattern]
                                 [--sas-token]
                                 [--source-account-key]
                                 [--source-account-name]
                                 [--source-container]
                                 [--source-sas]
                                 [--source-share]
                                 [--source-uri]. The 1th example of the child command would be to use it to 'copy multiple blobs to a blob container  use  az storage blob show  to check the status of the blobs   autogenerated', the syntax is: az storage blob copy start-batch --account-key 00000000 --account-name MyAccount --destination-container MyDestinationContainer --source-account-key MySourceKey --source-account-name MySourceAccount --source-container MySourceContainer. The parameter '--account-key' is optional. storage account key. must be used in conjunction with storage account name. environment variable: azure_storage_key.. The parameter '--account-name' is optional. storage account name. related environment variable: azure_storage_account. must be used in conjunction with either storage account key or a sas token. if neither are present, the command will try to query the storage account key using the authenticated azure account. if a large number of storage commands are executed the api quota may be hit.. The parameter '--auth-mode' is optional. the mode in which to run the command. "login" mode will directly use your login credentials for the authentication. the legacy "key" mode will attempt to query for an account key if no authentication parameters for the account are provided. environment variable: azure_storage_auth_mode.. The parameter '--connection-string' is optional. storage account connection string. environment variable: azure_storage_connection_string.. The parameter '--destination-container -c' is optional. the blob container where the selected source files or blobs will be copied to.. The parameter '--destination-path' is optional. the destination path that will be prepended to the blob name.. The parameter '--dryrun' is optional. list the files or blobs to be uploaded. no actual data transfer will occur.. The parameter '--pattern' is optional. the pattern used for globbing files or blobs in the source. the supported patterns are '*', '?', '[seq]', and '[!seq]'. for more information, please refer to https://docs.python.org/3.7/library/fnmatch.html.. The parameter '--sas-token' is optional. a shared access signature (sas). must be used in conjunction with storage account name. environment variable: azure_storage_sas_token.. The parameter '--source-account-key' is optional. the account key for the source storage account.. The parameter '--source-account-name' is optional. the source storage account from which the files or blobs are copied to the destination. if omitted, the destination account is used.. The parameter '--source-container' is optional. the source container from which blobs are copied.. The parameter '--source-sas' is optional. the shared access signature for the source storage account.. The parameter '--source-share' is optional. the source share from which files are copied.. The parameter '--source-uri' is optional. a uri specifying a file share or blob container from which the files or blobs are copied..
