Date: Mon, 20 Feb 2012 00:55:18 -0500 Message-ID: <4F41E046.6000208@jodybruchon.com> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-8086-owner@vger.kernel.org List-ID: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: linux-8086@vger.kernel.org I'm pleased to announce my development of a sub-project I am coining "BusyELKS" which serves the same purpose for ELKS that BusyBox does for larger Linux systems. I have spent most of my evening combining the files under elkscmd/sh_utils into a unified binary that executes the requested command based on its invocation name, and the savings just for sh_utils is awesome! Ignoring the "uname" tool which currently does not compile, the binary size total drops from 61920 to 46732, a whopping 15188-byte (24.5%) drop in size!

Even if I can only unify the utilities by category, we can look forward to significant space savings from this effort. Once I've got the structure cleaned up a bit and some disparities merged together, I'll commit BusyELKS to Git. Stay tuned. Jody Bruchon
