-r, -R, --recursive- Remove directories and their contents recursively.

-i- Prompt before every removal.
-v, --verbose- Explain what is being done.
--preserve-root- Refuse to act on / (the default).
Gotchas
- There is no undelete. And
rm dir/*on a directory with thousands of files gives "Argument list too long" - usefind dir -type f -delete.
