NAME

       zckdl — download a zchunk file

SYNOPSIS

       zckdl [--fail-no-ranges] [-q | --quiet] [-s file | --source=file] [-v | --verbose] url
       zckdl -? | --help | --usage | --version

DESCRIPTION

       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
