A file compression utility.
Bzip2 is a freely available, patent-free, high quality data compressor.
Bzip2 compresses files to within 10 to 15 percent of the capabilities
of the best techniques available. However, bzip2 has the added benefit
of being approximately two times faster at compression and six times
faster at decompression than those techniques. Bzip2 is not the
fastest compression utility, but it does strike a balance between speed
and compression capability.
Install bzip2 if you need a compression utility.
This is the README for bzip2, a block-sorting file compressor, version
1.0.3. This version is fully compatible with the previous public
releases, versions 0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1 and 1.0.2.

bzip2-1.0.3 should compile without problems on the vast majority of
platforms. Using the supplied Makefile, I've built and tested it
myself for x86-linux and x86_64-linux. With makefile.msc, Visual C++
6.0 and nmake, you can build a native Win32 version too. Large file
support seems to work correctly on at least alpha-tru64unix and
x86-cygwin32 (on Windows 2000).
When I say "large file" I mea
bzcmp, bzdiff - compare bzip2 compressed files
