zck - Man Page

The zck utility creates a new zchunk file from the data in the specified input file.

NOTE: If no output file is specified using the -o option, the zck utility will place the new file with the .zck extension in the current working directory, not in the directory where the original file resides.

The zck utility accepts the following optional arguments:

-D, --dict

Set the zstd compression dictionary to the specified file.

-m, --manual

Do not do any automatic chunking (implies -s).

-o, --output

Output to the specified file.

-s, --split

Split chunks at the beginning of the specified string.

-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.

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

Create (in the current directory) a zchunk-compressed words.zck file from a dictionary:

zck /usr/share/dict/words

The same, but specify an output file:

zck -o /tmp/words.txt.zck /usr/share/dict/words

Generate a zchunk file with chunks separated on HTML sections:

zck -s '<h2>' doc.html
