Last checked against version &bzip2-contversion; bunzip2 decompresses files that are compressed with bzip2. bzcat (or bzip2 -dc) decompresses all specified files to the standard output. bzcmp and bzdiff are used to invoke the cmp or the diff program on bzip2 compressed files. bzegrep, bzfgrep, and bzgrep invoke either egrep, fgrep, or grep (respectively) on bzip2-compressed files. 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 (such as the traditional gzip utility) 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 is the library for implementing lossless, block-sorting data compression, using the Burrows-Wheeler algorithm.
