Last checked against version &bzip2-contversion; bunzip2 (link to bzip2), bzcat (link to bzip2), bzip2, bzip2recover, bzless and bzmore bunzip2 decompresses files that are compressed with bzip2. bzcat (or bzip2 -dc) decompresses all specified files to the standard output. bzip2 compresses files using the Burrows-Wheeler block sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than that achieved by more conventional LZ77/LZ78-based compressors, and approaches the performance of the PPM family of statistical compressors. bzip2recover recovers data from damaged bzip2 files. bzless is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy terminal, like less. bzmore is a filter which allows examination of compressed or plain text files one screenful at a time on a soft-copy terminal, like more. libbz2.[a,so] libbz2 is the library for implementing lossless, block-sorting data compression using the Burrows-Wheeler algorithm.
