scripts/bash/usr-local-bin

Simple bash scripts I have in `/usr/local/bin` that may be trivial to recreate,
but why reinvent the wheel.

## Does this make sense for Flatpaks?

```bash
tail -n +1 /var/lib/flatpak/exports/bin/*
```

## Snap?

`/usr/local/bin` is more likely to be in `$PATH` than the usual Snap
vriants. If they are in $PATH, note `sudo snap alias ORIGINAL NEW`
