A.4.2.1. Bzip2

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.

A.4.2.2. Bunzip2

Bunzip2 decompresses files that are compressed with bzip2.

A.4.2.3. bzcat

bzcat (or bzip2 -dc) decompresses all specified files to the standard output.

A.4.2.4. bzip2recover

bzip2recover recovers data from damaged bzip2 files.
