The reason you don't want to use yes, I assume, is that at some point the maintainer scripts might stop and prompt you, and blindly answering yes to that question could be catastrophically wrong. Seperating that into an "only answer yes to prompts that come from the package manager" seems reasonable to me. -- -------------------------------------------------------------------------- | Stephen Gran | You will be misunderstood by everyone. | | steve@lobefin.net | | | http://www.lobefin.net/~steve | | -------------------------------------------------------------------------- Attachment:
