So you created a file (somehow) with a wierd character in it?  Something like:
	-f
or
	*

Well, now you can remove it without worry.  Just cd to the directory and:
	ls -i
to get the inode number.

Plug that into the find statement below and you are done!
	find . -inum acutal_inode_number -exec rm {} \;


For example:
	find . -inum 235942570 -exec rm {} \;
