I'm using terminal-ide http://code.google.com/p/terminal-ide/ which is basically a terminal for android with all sorts of utilities. One is able to create bash scripts for example. Is there a way to create an icon on the home screen that will launch one of these scripts?
Terminal-ide doesn't appear to have that feature yet, but it does have an issue tracker where you could request it. As it's an open-source program, you might even be able to add the feature yourself if you know (or are willing to teach yourself) a little about how Android apps are written.
