No. There's nothing like that available.

What sort of commands are you thinking of? Most tools require human interaction, such as "click here" or "drag there". A script is great for drawing the same rectangle, with the same stroke and fill, at the same position and size in a thousand files. But if you want to have it drawn at another position or with another fill color, you'll have to rewrite the script.
There are already scripts to batch convert documents to PDF and other export formats (check out Peter Kahrel's site for those).
That said, the basics of looping over a user selectable folder and its subfolders and doing *something* on each file is fairly straightforward. I do that when I need to update paragraph styles in a set of documents for a single book, for example.
Scripting within indesign is ONE option, but one avenue that i've recently discovered is within the operating system itself, and for me that is the Mac OS. Have been using automator to drag and drop indesign files onto an icon to have the "droplet" run various tasks. It's more of a visual interface and IMHO easy to use.
