But, mind you, don’t quote me on that since I am not an expert on compression algorithms. I believe it is most efficient in compressing text since it works by grouping characters that appear frequently together. I won’t go into much more detail on the algorithm, but there is some information on Wikipedia about it if you really want to know more about it. It was originally released in 1996 by Julian Seward.īzip2 uses an algorithm called the Burrows-Wheeler transform. What are bz2 files?īzip2 is a compression format that is said to be considerably more efficient than many other compression algorithms.
There is more you can do to work with bzip2 files. Bzgrep extracts the the file and feeds it directly to grep. To grep a file just do “bzgrep pattern filename.bz2”. How to grep bz2 files: The bzip2 package has a binary called bzgrep which does exactly that. Of course there was, but it took a little bit of searching to find it, so I decided to research this a little better and write some information about how to work with these files. I knew there had to be a tool to grep bz2 files like there is for some other archive formats. Extracting all the files and seemed like such a waste of time and space. I was working on a project today where I had a directory full of bz2 files that I needed to search.
