Bzip2
Bzip2 is a freely available, patent-free, high-quality data compressor. It provides significantly better compression than traditional gzip compressors, especially for text files, by using the Burrows-Wheeler block sorting text compression algorithm combined with Huffman coding.
Features
- High compression ratio, particularly effective on text files
- Patent-free implementation
- Cross-platform compatibility
- Recovery tool for damaged compressed files
- Standard Unix-style command-line interface
Included Programs
- bzip2: Compresses files using the Burrows-Wheeler algorithm
- bunzip2: Decompresses bzip2 compressed files (link to bzip2)
- bzcat: Decompresses files to standard output
- bzip2recover: Attempts to recover data from damaged bzip2 files
- bzgrep, bzegrep, bzfgrep: Search within bzip2 compressed files
- bzdiff, bzcmp: Compare bzip2 compressed files
- bzmore, bzless: View bzip2 compressed files
Library
- libbz2: Shared library providing bzip2 compression and decompression functions for other applications
Installation Notes
This package follows the Linux From Scratch installation guidelines, including:
- Installation of shared library with proper symlinks
- Relative symbolic links for portability
- Documentation installation
- Removal of unnecessary static library
