Overview

The zckdl utility attempts to download a zchunk file in an optimized way, taking into consideration the chunked structure.

The zckdl utility accepts the following optional arguments:

--fail-no-ranges

If the server does not support ranges, fail instead of downloading the whole file.

-q | --quiet

Quiet operation; only display warning and error messages. If specified twice, only display error messages.

-s | --source

Specify the file to use as a source with the premise that most of the chunks in the downloaded file will be the same.

-v, --verbose

Verbose operation; display some diagnostic output.

-?, --help

Display program usage information and exit.

--usage

Display brief program usage information and exit.

--version

Display program version information and exit.

Exit status

The zckdl utility exits 0 on success, and >0 if an error occurs.

Examples

Download a zchunk file that is hopefully not much different from the previous version:

zckdl -s doc1.txt.zck https://example.com/doc2.txt.zck
