The efficacy of the program to extract some damaged parts of files in otherwise inaccessible tapes or discs is worthwhile.
The simplicity and reliability of the program have earned it many laurels but there has been some criticism for its lack of archiving ability. bzip2 file compression can convert almost everything that you may test it with. bzip2 is used by a few million people around the world. You would use the bzip2-105-x86-win32.exe file to install. The total size of the file to be downloaded is 76KB. There are no specific requirements or additional specifications that must be satiated.
#Tar compress bz2 windows#
It is compatible with Windows 2000 and XP, subsequently all later versions. The file compression program can be downloaded and installed for free. Although not an archiving tool, the program can extract undamaged files in disks or tapes that have errors. As per the information published by the developer, the file compression program is capable of compressing files down to 15% or 10% of other available techniques and operates at twice the compression speed and six times the decompression speed than gzip. The simple operation and quick decompression or extraction would suit many heavy users. There are specific options to overwrite files, to suppress errors and compel compression. It cannot recover from syntax errors but it can force compression and even decompress damaged archives. Initiating and running the program is a cakewalk. The command line enabled file compression program has fifteen options. bz2 as its filename extension, application/x-bzip2 as the media type on internet and 2 as the uniform type identifier.īzip2 is suitable for power users. The compression application works on all major operating systems and is available as a BSD-like license. Julian Seward is still in charge of maintaining the program.
#Tar compress bz2 archive#
The program can compress files but cannot archive them. bzip2 compression program is based on Burrows–Wheeler algorithm.
The version 1.0.6 was released on the 20th of September in 2010. The last stable release was seven years ago. It has remained an open source program, available to all for free, for over twenty two years now. If you are concerned about speed, you could investigate alternative algorithms, such as those used by gzip or lzop.The bzip2 file compression program was developed by Julian Seward and launched on the 18th of July in 1996. tar.bz2 īzip2 uses a slow compression algorithm. So to use that with tar, you could for example do: $ BZIP2=-1 tar -create -bzip2 -file. This gives a convenient way to supply default arguments. In that order, and will process them before any arguments read from theĬommand line.
#Tar compress bz2 manual#
From the manual page bzip2(1): bzip2 will read arguments from the environment variables BZIP2 and BZIP, It is also possible to set bzip2 options through the environment variable BZIP2. tar with tar -> bzip it with bzip2 -> write it to. My favorite way, the UNlX way, is one where you use every tool independently, and combine them through pipes. You can set bzip2 block size when using tar in a couple of ways. And -best merely selects the defaultĪs you want faster compression with less regards to compression ratio, using bzip2, you seem to want the -1 (or -fast) option. The -fast and -best aliases are primarily for GNU gzipĬompatibility. From the manual page bzip2(1): -1 (or -fast) to -9 (or -best)
