Dennis Ritchie has been heard to say, roughly, "You can't build a secure restricted shell by trying to take things out of the regular shell. Every one of those I've seen, I've broken." The "restricted shell" that Paul is referring to is almost certainly "one of those". So beware. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
