How do I convert tar.bz2 to tar.gz?

Question

I'm new in Linux, is this conversion possible?

Do I need to compress and decompress all content?

You might consider using `xz` instead of `gzip` as it can compress better at the expense of using more time and memory. — jftuga, Oct 21 '16 at 22:42

And GZ to BZip2: `gunzip -c < file.tar.gz | bzip2 -c > file.tar.bz2` – Le Quoc Viet Oct 17 '12 at 02:50

Also consider `gzip -9 -c ...` for tighter compression. – jftuga Oct 21 '16 at 22:42

You need to decompress, and then compress.

You can convert like so:

 bunzip2 -c -d file.tar.bz2 | gzip -v9 > file.tar.gz

Yes, you need to decompress and compress the content (because compression is not "compositional").
