bunzip2 decompresses bzipped files. bzcat decompresses to standard output. bzcmp runs cmp on bzipped files. bzdiff runs diff on bzipped files. bzgrep and friends run grep on bzipped files. bzip2 compresses files using the Burrows-Wheeler block sorting text compression algorithm with Huffman coding. The compression rate is generally considerably better than that achieved by more conventional compressors using LZ77/LZ78, like gzip. bzip2recover tries to recover data from damaged bzip2 files. bzless runs less on bzipped files. bzmore runs more on bzipped files. libbz2* is the library implementing lossless, block-sorting data compression, using the Burrows-Wheeler algorithm.
