Yes, sourcing can follow the symlink, but the problem is how to find the path of sourcing file/symlink. Say if we make `spark-shell` as a symlink and add to /usr/bin, when we execute this `spark-shell` in any directory, how to identify the path of sourcing file? If sourcing file is not linked to `/usr/bin/xx`, we still need to find out where Spark is installed.
