Oct 27, 2024 · bzip2 is mono-threaded, which means it will take a long time to decompress a large file. To decompress a .bz2 file multithreadedly, you can use the free, open source program lbzip2: sudo apt-get install lbzip2 lbzip2 -d my_file.bz2 -d indicates you wish to decompress the file. It would automatically determine how many threads it will use.

Gzip and bzip2, as well as xz and lzop, are functionally equivalent. (There once was a bzip, but it seems to have completely vanished off the face of the world.) Other common compression formats are zip, rar and 7z; these three do both compression …

bzip2 has been made mostly obsolete by xz, and zstd is likely the best for most workflows. Minimum file size: xz is still the best when it comes to minimal file sizes. Compression is fairly expensive though, so faster compression algorithms are better suited if that is a concern.

The proper extension for bzip2 compressed files is .bz2, while the .bz extension is for bzip compressed files. bzip uses arithmetic encoding (which is a patented algorithm), so bzip2 was created in 1997 as a patent-free alternative. As a result, bzip2 and bzip are incompatible.

I've just downloaded phpBB3 and saw they offer a bz2 (1.51 MB) and a zip (2.35 MB) download. This is the reason why I want to know if the ZIP file format has any advantages over bzip2. According to the Wikipedia article, the zip-files can be compressed using the bzip2-compression algorithm. Why is the zip-file then that much bigger?

Jan 14, 2015 · The official bzip2 command line utility is available for Windows. Installation: Download and unpack the file bzip2-1.x.x-win-x64.zip for a 64 bit Windows, or bzip2-1.x.x-win-x86.zip for a 32 bit Windows. Install msvcr120.dll according to the instructions: All binaries depend on the Visual Studio 2013 C Runtime Library (msvcr120.dll).

I'm comparing compression functions, and I'm surprised by what I'm seing. Maybe I'm doing something wrong, but everything I've tested has been more compressed by gzip than bzip2! I was under the impression that bzip2 was better than gzip. Can someone give an example of data that would demonstrate this? Thanks.

And from the documentation: If the file does not end in one of the recognised endings, .bz2, .bz, .tbz2 or .tbz, bzip2 complains that it cannot guess the name of the original file, and uses the original name with .out appended. –
