What is tar.bz2? What is the difference between tar.bz with tar.bz2?

I suggest reading up on this topic if you are interested.

Basically, tar concatenates the files into a contiguous archive (Tape Archive).

BZ, BZ2 and GZ are compression algorithms to make the archive smaller. bz2 will achieve greater compression ratios than gz, however this comes at the expense of time and processor power to do so.

Normally, you will see tar.gz or tar.bz2 as gz and bz2 are unable to compress more than one file. Therefore, a group of files can be made into a single tar archive and then compressed.


I hope this helps

A bzip2 compress tar archive.

A typo/spelling mistake. Unless of course you meant
" What is the difference between tar.gz with tar.bz2? "
In that case it's the difference between a gzip compressed
and a bzip2 compressed tar archive.

Furthermore the tar command has options to manage both the compression algorithms:
