Find all recipes in a Yocto layer

bitbake-layers show-recipes -l <layer>

This assumes:

• The layer is in your bblayers.conf
• That the bitbake oe-init-build-env has been sourced into your environmental variables

To find if a specific recipe is in a layer just pipe to grep as below:

bitbake-layers show-recipes -l <layer> | grep <recipe-name>
