How to refer to a file with name beginning `--`?

Question

How can I rename or open or do anything with this file?

Everything I try (rm, mv, cat, less, vi) gives unrecognised option '--.html'

So far, only a full ls piped to grep has been useful, or even usable.

stewart$ ls -l | grep html
-rw-rw-r-- 1 stewart stewart  18262 Mar 13 06:08 --.html

Answer 1

OK, I worked it out. This worked:

rm ./--.html
