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. Lzip decompresses almost as fast as gzip and compresses better than bzip2, which makes it well suited for software distribution and data archiving.
The lzip file format is an improved successor of the unsafe and deprecated lzma-alone file format.
Lzip will correctly decompress a file which is the concatenation of two or more compressed files. The result is the concatenation of the corresponding uncompressed files. Integrity testing of concatenated compressed files is also supported.
Lzip can produce multi-member files and safely recover, with lziprecover, the undamaged members in case of file damage.
Lzip can also split the compressed output in volumes of a given size, even when reading from standard input.
