In fact, your working tree will not be different as the\nbranch was started where you were, e.g. on the \"default\" branch. The\ndifference will be that commits made from now on will be placed on the\nbranch named \"origin/branch\".\n\n\nThe \"branch\" branch is there, but it is only referenced by the remote\n\"origin\". I believe what you want to do is to execute the following command:\n\ngit branch branch origin/branch\n^-> This one creates a local branch named \"branch\" that tracks the\n\"origin/branch\" remote branch. It will not switch to it, though. You\nneed to do \"git checkout branch\" afterwards to have your worktree\nadjusted. By doing the above command you effectively tell git that you'd\nlike to work on the top of the point \"origin/branch\". Your commits will\nbe local until they are pushed to origin, hence the need to have a local\nbranch that can possibly point to a different place in history.\n\n\nHope that was not too confusing :\\ don't hesitate to ask for precisions ;)\n\n> On Wed, Jun 16, 2010 at 10:32 PM, Thomas Anderson wrote:\n>> I guess what I was trying to do was checkout a remote branch.
