using Duc
Use duc index "/foo/bar" to create an index of the /foo/bar directory's contents, then duc gui "/foo/bar" to view that directory's contents as a sunburst chart, or duc ui "/foo/bar" to view that directory's contents using an ncurses console interface.
prior work
The scripts for creating an index of a directory and viewing that directory were introduced to me by the “Usage” section of the Duc website.
