Well, I personally keep the TRUNK and any branches I need checked out all the time (as opposed to trying to switch a single sandbox from branch to trunk and back). So, for me, doing a diff on the TRUNK is a simple matter of merely changing over to my TRUNK folder and doing the diff. That's what I was really suggesting. Though, like you said, if you don't already have a copy of the TRUNK checked out, then you would have to do that. But once done, it's done, and you just have to make sure it is up to date before doing a diff like we're talking about. I agree that it is too bad that "HEAD" does not refer to the top of the TRUNK when you're working on a branch. I think there was some discussion some time ago about the idea of introducing a new keyword (like "TOP" or "TIP" or something like that) that would always refer to the current revision on the TRUNK regardless of where you are currently working, but I don't know what came of it. > The other question is whether HEAD will mean what _YOU_ > think it means, even when you are in a trunk checkout.

It is my understanding that HEAD always refers to the latest revision on the branch you are working in. So, if you are in the TRUNK, then it is the head of the trunk. If you are in a branch, then it is the head of the branch. In other words, "HEAD" is relative to your current location. Also, if you are up to date on the branch/trunk, you don't even need to use "HEAD". You can just say, "cvs diff -r <tag>" and that will give you the differences between the tag and the current head (because "HEAD" is redundant if your local sandbox is up to date). I've never needed to use "HEAD" myself, so I could be mistaken; but I believe I understand its use correctly. - Dennis
