Dumping BitBake's environment

When developing or debugging package or image recipes, it is very common to ask BitBake to list its environment both globally and for a specific target, be it a package or image.

To dump the global environment and grep for a variable of interest (for example, DISTRO_FEATURES), use the following command:

$ bitbake -e | grep -w DISTRO_FEATURES

Optionally, to locate the source directory for a specific package recipe such as BusyBox, use the following command:

$ bitbake -e busybox | grep ^S= 

You could also execute the following command to locate the working directory for a package or image recipe:

$ bitbake -e <target> | grep ^WORKDIR=
