Yea, those are great suggestions and I will test them out too.
I thought about it but have not played with piping a lot so I did not want
to spend a lot of time down that pathway for now, but
it's definitely something that I need to get better at using.
I'm not an expert by any means and just put that together to take a
directory full of txz files and repackage them into tbz files so that I can
possibly use them within the mfsBSD scripts.
It can definitely be improved upon by better skill people.
