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?

Solution 1

bunzip2 -c < file.tar.bz2 | gzip -c > file.tar.gz

Solution 2

You need to decompress, and then compress.

You can convert like so:

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

You might consider using xz instead of gzip as it can compress better at the expense of using more time and memory.

And GZ to BZip2: gunzip -c < file.tar.gz | bzip2 -c > file.tar.bz2

Also consider gzip -9 -c ... for tighter compression.
