This looks like a fun and helpful tool! (Perhaps best to ignore the notice from lshw and not run it as root, ha ha. Maybe even only in some kind of sandbox. I bet they could add a --safe flag so it would make an on-the-fly Docker image with a copy of your cwd, and run the commands in there. Then you have different problems I suppose, but still....)

I've never seen `paste - -` before, but that is amazing too! I can't count how many times I've wanted something like that. Surely that will help my own shell pipelines in the future.

Also I've never seen `foo |& bar` before. What a neat idea! The surprisingly-valid creativity of it reminds me of Duff's Device. Has anyone else ever found uses for that idiom?

After so many years working in the shell, it's such a rare and delightful treat to learn new tricks. Thank you for sharing this with us!
