All programs want argument arrays, not un-split lines, and if you don't have the shell split it you'll have to do it yourself. words works fine.

Actually, it's no problem having any of those characters in your arguments, it's just that they'll be passed literally (which may or may not be what your user wants--sometimes it's really convenient to avoid multiple layers of escapes). The one constraint that using words makes is that it doesn't allow you to specify arguments that contain a space. David
