unzckdecompress a file in the zchunk format

unzck [-c | --stdout] [--dict] [-v | --verbose] file

unzck -? | --help

unzck --usage

unzck --version

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

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

The unzck utility accepts the following optional arguments:

, --stdout
Extract the data to the standard output stream, do not write it to a file.
Only extract the zstd compression dictionary.
, --verbose
Verbose operation; display some diagnostic output.
-?, --help
Display program usage information and exit.
Display brief program usage information and exit.
Display program version information and exit.

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

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
