Download File by Name Command

V3.13.1

This command downloads a file and stores it in a local file location.

If the tqdm library is installed, a progress bar is displayed on a standard error output (stderr). Without it, simple text progress is printed. Set the –-noProgress parameter to disable progress reporting, which may improve performance.

Use the --threads parameter to manually adjust the number of threads that are used in the operation. Otherwise, the number of threads is automatically chosen.

To access SSE-C-encrypted files, set the --sourceServerSideEncryption=SSE-C parameter. The default algorithm is set to AES256 which you can change with the --sourceServerSideEncryptionAlgorithm parameter. Using SSE-C requires that you provide the B2_SOURCE_SSE_C_KEY_B64 environment variable, containing the base64-encoded encryption key.

Use the -–write-buffer-size parameter to set the size (in bytes) of the buffer that is used to write files.

Use the -–skip-hash-verification parameter to disable the hash check on downloaded files.

Use the --max-download-streams-per-file parameter to set a maximum number of streams to use for a parallel downloader.

Required Capabilities

• readFiles

Positional Arguments

• bucketName
• b2FileName
• localFileName

Named Arguments

• --noProgress
  Default: False
• --sourceServerSideEncryption
  Possible value: SSE-C
• --sourceServerSideEncryptionAlgorithm
  Possible value: AES256
  Default: “AES256”

V3.0.2

This command downloads a file and stores it in a local file location.

If the tqdm library is installed, a progress bar is displayed on a standard error output (stderr). Without it, simple text progress is printed. Set the –-noProgress parameter to disable progress reporting.

To access SSE-C-encrypted files, set the --sourceServerSideEncryption=SSE-C parameter. The default algorithm is set to AES256 which you can change with the --sourceServerSideEncryptionAlgorithm parameter. Using SSE-C requires that you provide the B2_SOURCE_SSE_C_KEY_B64 environment variable, containing the base64-encoded encryption key.
