What opens a BZ2 file?

What is the bzip2 command used for?

Data decompression, or just decompression, is the process of restoring compressed data back into a form in which it is again useful.

How do I reverse a bzip2 compression file?

To reverse the compression process and get the original file back that you have compressed, you can use the bzip2 command itself or bunzip2 which is also part of the bzip2 package.
