Huh? Too much copypasta? :-)

That would not work as expected, because **/.txz will be an
empty list, and the input file argument for bzip2 is does not
exist.

If the directory portions with $file will be handled correctly,
you decompress bla.tbz to bla.tar; if you then compress bla.tar,
bzip2 will substitute .tar for... or does it append... no, I
don't know, but I'm almost sure it will create bla.tar.bz2.
So it's probably better to be explicit than to assume something
and use "name construction" to get what you want.

Maybe something like this:

for file in */*.txz; do unxz -c $file | bzip2 $(file%.txz}.tbz; done

With this approach, you avoid creating temporary files.

NB: Constructred from memory, not from experiment.



We all should drink more coffee. The emperor will be pleased. :-)
