ZCK_DELTA_SIZE(1) General Commands Manual ZCK_DELTA_SIZE(1) 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 deter- mines 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 SEE ALSO unzck(1), zck(1), zck_gen_zdict(1), zck_read_header(1), zckdl(1) AUTHOR The zck_delta_size utility was written by Jonathan Dieter <jdieter@gmail.com>.
