There is a very nice calculator script that is able to convert any units of measurement to and fro to other units. This would be great to convert an old unit of measurement to a new unit.
Install this very easily.

This is one very useful CLI tool for sure.

This looks very good indeed, a good addition to any Linux machine.
Download the Rust source here: https://github.com/sharkdp/bat#installation.
A patch for cp and mv that lets you see the progress of the entire job rather than just single files. yeah, you could just use rsync but sometimes you really don’t need to use rsync but still want to see how long it will take.
https://github.com/jarun/advcpmv. This requires the source for cp and mv. But this would be a very useful patch.
