NAME

       unzck — decompress a file in the zchunk format

SYNOPSIS

       unzck [-c | --stdout] [--dict] [-v | --verbose] file
       unzck -? | --help
       unzck --usage

DESCRIPTION

       The unzck utility extracts the original file from a zchunk-compressed one.

       NOTE:  The  unzck  utility  will  place  the  new  file without the .zck extension in the current working
       directory, not in the directory where the original file resides.

       The unzck utility accepts the following optional arguments:

       -c, --stdout
               Extract the data to the standard output stream, do not write it to a file.

       --dict  Only extract the zstd compression dictionary.

       -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 unzck utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

       Create (in the current directory) an uncompressed words file from a compressed one:

             unzck /mnt/xfer/words.zck

       Do not create the words file, but send the contents to the standard output stream:

             unzck -c /mnt/xfer/words.zck
