Remove words beginning with a certain character from a file

Hi,

how could you go about removing words that begin with a certain character.

assuming that this character is '-' I currently have

Code:
echo "-hello" | sed s/-/""/

which replaces the leading dash with nothing but I want to remove the whole word, even if there are multiple words beginning with '-'

thanks

skinny
