                             [--validate-content]. The 1th example of the child command would be to use it to 'upload all files that end with  py unless blob exists and has been modified since given date', the syntax is: az storage blob upload-batch -d mycontainer --account-name mystorageaccount --account-key 00000000 -s <path-to-directory> --pattern "*.py" --if-unmodified-since 2018-08-27T20:51Z. The 2th example of the child command would be to use it to 'upload all files from local path directory to a container named  mycontainer', the syntax is: az storage blob upload-batch -d mycontainer -s <path-to-directory>. The 3th example of the child command would be to use it to 'upload all files with the format  cli 2018 xx xx txt  or  cli 2019 xx xx txt  in local path directory', the syntax is: az storage blob upload-batch -d mycontainer -s <path-to-directory> --pattern "cli-201[89]-??-??.txt". The 4th example of the child command would be to use it to 'upload all files with the format  cli 201x xx xx txt  except cli 2018 xx xx txt  and  cli 2019 xx xx txt  in a container', the syntax is: az storage blob upload-batch -d mycontainer -s <path-to-directory> --pattern "cli-201[!89]-??-??.txt". The parameter '--destination -d' is required. It is used to the blob container where the files will be uploaded.. The parameter '--source -s' is required. It is used to the directory where the files to be uploaded are located.. 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 '--content-cache --content-cache-control' is optional. the cache control string.. The parameter '--content-disposition' is optional. conveys additional information about how to process the response payload, and can also be used to attach additional metadata..

The parameter '--content-md5' is optional. the content's md5 hash.. The parameter '--content-type' is optional. the content mime type.. The parameter '--destination-path' is optional. the destination path that will be prepended to the blob name.. The parameter '--dryrun' is optional. show the summary of the operations to be taken instead of actually uploading the file(s).. The parameter '--if-match' is optional. an etag value, or the wildcard character (*). specify this header to perform the operation only if the resource's etag matches the value specified.. The parameter '--if-modified-since' is optional. commence only if modified since supplied utc datetime (y-m-d't'h:m'z').. The parameter '--if-none-match' is optional. an etag value, or the wildcard character (*).. The parameter '--if-unmodified-since' is optional. commence only if unmodified since supplied utc datetime (y-m-d't'h:m'z').. The parameter '--lease-id' is optional. the active lease id for the blob.. The parameter '--max-connections' is optional. maximum number of parallel connections to use when the blob size exceeds 64mb.. The parameter '--maxsize-condition' is optional. the max length in bytes permitted for an append blob.. The parameter '--metadata' is optional. metadata in space-separated key=value pairs. this overwrites any existing metadata.. The parameter '--no-progress' is optional. include this flag to disable progress reporting for the command.. 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 '--socket-timeout' is optional. the socket timeout(secs), used by the service to regulate data flow.. The parameter '--timeout' is optional. request timeout in seconds. applies to each call to the service.. The parameter '--type -t' is optional. defaults to 'page' for *.vhd files, or 'block' otherwise. the setting will override blob types for every file.. The parameter '--validate-content' is optional. specifies that an md5 hash shall be calculated for each chunk of the blob and verified by the service when the chunk has arrived..
