![]() ![]() Lzip will automatically use the smallest possible dictionary size 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. 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". If the cause of file corruption is damaged media, the combination GNU ddrescue + lziprecover is the best option for recovering data from multiple damaged copies. Lziprecover is a data recovery tool for lzip compressed files able to repair slightly damaged files, recover badly damaged files from two or more copies, and extract undamaged members from multi-member files. Software tools that decompress both formats or can convert lzma-alone files to lzip format are listed below, in the Links section. The lzip file format (.lz) is an improved successor of the unsafe and deprecated lzma-alone file format (.lzma). Lzip decompresses almost as fast as gzip and compresses better than bzip2, which makes it well suited for software distribution and data archiving. Lzip 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. ![]()
