## Contents of Bzip2

(Last checked against version 1.0.2.)

Bzip2 is a block-sorting file compressor which generally achieves a better compression than the traditional `gzip` does.

Bzip2 installs the following files:

### Program Files

bunzip2 (link to bzip2), bzcat (link to bzip2), bzcmp, bzdiff, bzegrep, bzfgrep, bzgrep, bzip2, bzip2recover, bzless and bzmore

### Library Files

libbz2.a, libbz2.so (link to libbz2.so.1.0), libbz2.so.1.0 (link to libbz2.so.1.0.2) and libbz2.so.1.0.2

## Descriptions

(Last checked against version 1.0.2.)

### Program file descriptions

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.

### Library file descriptions

libbz2 is the library implementing lossless, block-sorting data compression, using the Burrows-Wheeler algorithm.
