So why doesn't "rm foo" not error out with a nice message if it would be removeing the last link to foo? After all, that's the conservative thing to do, and if the user really wants to remove the last link: > If the user knows what they are doing then let them specify -f. Now you've decided that you know better what the user wants than they do. That's not what I expect from a Unix system. The claim was that that's not "what our users expect". I was pointing out that there's at least one user who expects - indeed, prefers - that the system do what they tell it to, without trying to protect them from themselves. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.
