Get Workspace Path in Terminal

Is there an easy way to get the path to the current workspace (i.e. the directory containing src, build, devel) with a bash command?

I could somehow extract it from $ROS_PACKAGE_PATH but I am wondering if there is an easier way.

$CMAKE_PREFIX_PATH typically contains the paths to the workspaces. Entries have devel or install suffixed though (it points to specific spaces, not the top-level workspace).

roscd (without any arg) cds into the top-level space sourced.

Not sure there is a command / tool for this.

@gvdhoorn Thanks, $CMAKE_PREFIX_PATH looks good. It still needs some processing to extract the path but at least it more deterministic than $ROS_PACKAGE_PATH.

Another way I have done this, albeit somewhat inelegant, is to use $(find aaa) to get an absolute path off a package and then tree down to it. $(find my_package)/../../my_file_in_workspace.
