Hi Raj,
What I am asking you is that how the yocto picks up components for /usr/bin folder of rootfs. Where do they exist before copying? I am sorry but I feel I do not need to write a recipe for adding just one of the commands. It is just that I need to add "ubiattach" to target /usr/bin of rootfs. That’s why I am asking where do I place my "ubiattach" command and there should also be a folder for this. Please clarify.
Thanks,
Harish.

Please keep the thread on list and avoid pm.
as I said you need
1. Write a recipe for your package
2. in do_install of the recipe you want to mention where it should be placed e.g.
install -D -m 0755 <your-binary> ${D}${bindir}/<your-binary>
would put it in /usr/bin on target when this package is included in image
3. Include the package in image via IMAGE_INSTALL
