LZMA Utils
LZMA Utils are legacy data compression software with high compression ratio. LZMA Utils are no longer developed, although critical bugs may be fixed as long as fixing them doesn't require huge changes to the code.
Users of LZMA Utils should move to XZ Utils. XZ Utils support the legacy .lzma format used by LZMA Utils, and can also emulate the command line tools of LZMA Utils. This should make transition from LZMA Utils to XZ Utils relatively easy.
Features
LZMA Utils are based on LZMA SDK 4.32. LZMA Utils consist of several components:
- gzip-like command line tools lzma, unlzma, and lzcat
- Scripts adapted from gzip to ease viewing, grepping, and comparing uncompressed contents of .lzma files
- lzmadec, a small decompression-only command line tool
- lzmainfo, a tool to view information about .lzma headers
- liblzmadec, a decompression-only library with stateful multi-call API
There are some benchmarks of an old version of LZMA Utils. The results of these benchmarks somewhat apply to the latest LZMA Utils too. XZ Utils tend to be significantly faster though (typically 20–30 % faster single-threaded compression at practically the same compression ratio).
Licensing
Most of LZMA Utils are under GNU GPLv2+ or GNU LGPLv2.1+. Some less important files are under GNU GPLv3+.
