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

Program file descriptions

bunzip2

bunzip2 decompresses files that are compressed with bzip2.

bzcat

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

bzcmp, bzdiff

bzcmp and bzdiff are used to invoke the cmp or the diff program on bzip2 compressed files.

bzegrep, bzfgrep, bzgrep

bzegrep, bzfgrep, and bzgrep invoke either egrep, fgrep, or grep (respectively) on bzip2-compressed files.

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 (such as the traditional gzip utility) and approaches the performance of the PPM family of statistical compressors.

bzip2recover

bzip2recover recovers data from damaged bzip2 files.

bzless

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

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.

Library file descriptions

libbz2

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