Imagine some kind of credit card (or wrist watch) sized smartphone with many (modular) interfaces, very fast and nearly infinite battery service life.

It runs a small (uClibc) busybox linux - very hardware independent.

Software is provided only by shell scripts using the tiny Almqvist shell (ash) - very software independent.

This side provides shell scripts to manage this operating system. Please help to improve these scripts.

For easy operating of this small gadget only six (!) keys are necessary (similar to a small remote control or a small touch screen):

UP, DOWN, LEFT, RIGHT, OK and KO.

Of course for purposes of programming a keyboard connection or ssh-input is possible.
