NAME

     zck — compress a file using the zchunk format

SYNOPSIS

     zck [-D file | --dict=file] [-m chunk | --manual=chunk] [-o file | --output=file]
         [-s string | --split=string] [-v | --verbose] file
     zck -? | --help | --usage | --version

DESCRIPTION

     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.

EXIT STATUS

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

EXAMPLES

     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
