NAME

       zck_delta_size — calculate the differences between two zchunk files

SYNOPSIS

       zck_delta_size [-v | --verbose] file1 file2
       zck_delta_size -? | --help | --usage | --version

DESCRIPTION

       The  zck_delta_size utility examines two zchunk compressed files and determines how similar they are: how
       many chunks are the same between the files, so that tools like e.g.   rsync(1)  or  zckdl(1)  could  only
       transfer the small parts that differ instead of the full files.  This is especially useful for structured
       files that have been compressed using the zck(1) tool's -s (--split) option.

       The zck_delta_size utility accepts the following optional arguments:

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

EXAMPLES

       Examine two zchunk files:

             zck_delta_size doc1.txt.zck doc2.txt.zck
