script-shell

App for AsteroidOS that provides an interface for running scripts on your watch.

script-shell lists scripts (executable files) in /home/ceres/script-shell. It then lets you run those scripts and displays some stdout messages and the state on the watch display.

Build and install

First install the SDK: https://wiki.asteroidos.org/index.php/Installing_the_SDK

Conventions for scripts

script-shell scans and displays all executable files installed in /home/ceres/script-shell.

Files must be executable (chmod 700 script.sh). Else they will be ingored.

File name

1. Files will be sorted alphanumericly.
2. Leading digits, followed by a _ will not be displayed.
3. File-extensions (everything after the .) will be ommited too.
4. - and _ signs will be replaced by a space ().

Example filename: 01_Hello-World.sh

Example script

#!/bin/sh# Lines on stdout that beginn with a `->` are getting displayed on the watch.# All other text output will be ignored.echo"-> Hello World"echo"ignored output"# A return value of 0 indicatates success. # All other return values are interpreted as error.exit 0
