DESCRIPTION

12     The zckdl utility attempts to download a zchunk file in an optimized way,
13     taking into consideration the chunked structure.
14
15     The zckdl utility accepts the following optional arguments:
16
17     --fail-no-ranges
18             If the server does not support ranges, fail instead of download‐
19             ing the whole file.
20
21     -q | --quiet
22             Quiet operation; only display warning and error messages.  If
23             specified twice, only display error messages.
24
25     -s | --source
26             Specify the file to use as a source with the premise that most of
27             the chunks in the downloaded file will be the same.
28
29     -v, --verbose
30             Verbose operation; display some diagnostic output.
31
32     -?, --help

34
35     --usage
36             Display brief program usage information and exit.
37
38     --version
39             Display program version information and exit.

EXIT STATUS

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

46     vious version:
47
48           zckdl -s doc1.txt.zck https://example.com/doc2.txt.zck
