# XZ Utils

XZ Utils is free general-purpose data compression software with high compression ratio. XZ Utils were written for POSIX systems but have been ported to a few non-POSIX systems as well.

## Features

- **High Compression Ratio**: XZ format provides very high compression ratio, typically better than gzip and bzip2
- **Fast Decompression**: Features an extremely fast decoder with speed in multiple GB/s per core
- **LZMA2 Algorithm**: Uses the improved LZMA2 compression algorithm
- **Multiple Formats**: Supports both legacy LZMA and modern XZ formats
- **Wide Compatibility**: Available on virtually all Unix-like systems

## Included Programs

The package includes numerous command-line utilities:

- `xz` - Compress or decompress files using the XZ format
- `unxz` - Decompress files using the XZ format
- `xzcat` - Decompress to standard output
- `lzma` - Compress or decompress files using the legacy LZMA format
- `unlzma` - Decompress files using the LZMA format
- `lzcat` - Decompress to standard output
- `xzdiff` - Run diff on XZ compressed files
- `xzgrep` - Run grep on XZ compressed files
- `xzless` - Run less on XZ compressed files
- `xzmore` - Run more on XZ compressed files

## Library

- `liblzma` - The library implementing lossless, block-sorting data compression using the Lempel-Ziv-Markov chain algorithm

## Usage Examples

Basic compression:
```bash
xz file.txt
```

Decompression:
```bash
unxz file.txt.xz
```

Decompress to stdout:
```bash
xzcat file.txt.xz
```

Compression with custom level:
```bash
xz -9 file.txt  # Maximum compression
```

## Installation

This package follows the Linux From Scratch (LFS) installation guidelines and includes all necessary components for a complete XZ Utils installation on Astrologue OS.
