XZ Utils is open source general-purpose data compression software with high compression ratio.
XZ (previously known as LZMA Utils) is the successor to the Lempel-Ziv/Markov-chain Algorithm compression format, which provides memory-hungry but powerful compression (often better than bzip2) and fast, easy decompression.
This package provides the command line tools for working with XZ compression, including xz, unxz, xzcat, xzgrep, and so on. They can also handle the older LZMA format, and if invoked via appropriate symlinks will emulate the behavior of the commands in the lzma package.
The XZ format is similar to the older LZMA format but includes some improvements for general use.
Features include:
- Primary compression algorithm is currently LZMA2.
- ‘File’ magic for detecting XZ files:
- crc64 data integrity check.
- Limited random-access reading support.
- Improved support for multithreading (not used in xz-utils).
- Support for flushing the encoder.
- Compress and decompress both the xz and lzma file formats.
