Lzip is a lossless data compressor intended for Unix-like systems. It uses a simplified form of the LZMA algorithm and places particular emphasis on reliable data storage, format stability and recovery from corruption.
The program is suitable for general-purpose file compression, software distribution and long-term archiving. Its format is designed to remain straightforward to decode and implement, reducing dependence on a particular compressor implementation.
An important characteristic of Lzip is its attention to integrity checking. Compressed members contain information that can help identify damaged data, while companion recovery tools can salvage valid portions of files in suitable circumstances.
This is free and open source software.
Key Features
- Lossless compression based on the LZMA algorithm.
- Produces files using the standard .lz format.
- Provides a command-line interface similar to gzip and bzip2.
- Includes integrity checks to detect corruption in compressed data.
- Supports multimember compressed files.
- Allows independently compressed members to be concatenated.
- Supports recovery of undamaged data through companion tools such as lziprecover.
- Provides configurable compression levels.
- Allows dictionary sizes to be adjusted according to memory and compression requirements.
- Supports compression and decompression through standard streams.
- Includes a test mode for checking compressed files.
- Lists compression statistics and information about compressed members.
- Supports reliable decoding through a documented and stable file format.
- Can be combined with tar for long-term compressed archives.
- Preserves file metadata where supported by the operating system.
