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 -

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:

Do not create the words file, but send the contents to the standard output stream:
unzck -c /mnt/xfer/words.zck
