One of the problems with this that probably occurs to everyone is that there are many more actions you can do with a file than there are files in a typical directory.  So you might say &gt; how file, and it might return 1000 things you can do with it.<p>To answer my own objection, &gt; how (or whatever the tool is called), or just the object itself as in the author&#x27;s example, could display categorized actions, or offer a way to navigate submenus, or it could limit initial output to things that a non-superuser would want to do and offer additional options for superusers to browse more advanced options (or assume they know what other tools exist and use them directly).
