![]() Added chapter 'Stream format' and appendix 'Reference source code' to the manual.configure: Options now accept a separate argument.Ignore option '-n, -threads' for compatibility with plzip.(show_header): Do not show header version.Show progress of compression at verbosity level 2 (-vv).It is important to appreciate that the decompression memory requirement is affected at compression time by the choice of dictionary size limit. Lzip will automatically use the smallest possible dictionary size for each member without exceeding the given limit. This allows the direct creation of multivolume compressed tar archives. Lzip can also split the compressed output in volumes of a given size, even when reading from standard input. Lzip can produce multimember files and safely recover, with lziprecover, the undamaged members in case of file damage. Integrity testing of concatenated compressed files is also supported. The result is the concatenation of the corresponding uncompressed files. This is especially true if you do not use the parallel implementations. Lzip will correctly decompress a file which is the concatenation of two or more compressed files. In this case, lzip will decline to write compressed output to a terminal, as this would be entirely incomprehensible and therefore pointless. If no file names are specified, lzip compresses (or decompresses) from standard input to standard output. Lzip is able to read from some types of non regular files if the "-stdout" option is specified. Each compressed file has the same modification date, permissions, and, when possible, ownership as the corresponding original, so that these properties can be correctly restored at decompression time. Lzip replaces every file given in the command line with a compressed version of itself, with the name "original_name.lz". ![]() xz-utils are written in C, with the compression library and basic utilities being public-domain. Lzip compresses better than bzip2 and decompresses almost as fast as gzip, which makes it well suited for software distribution and data archiving. Lzip has a recovery tool and a few extra promises. Zip is a lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface similar to the one of gzip or bzip2.
