By default the upstream branch is used, but a different commit can be specified in the arguments. +Assume the following history exists and the current branch is +`master`: + +------------ + D---C---B---A origin/master + ^ + | + master +------------ + +Then `git fast-forward` will advance the local `master` to `origin/master`: + +------------ + D---C---B---A origin/master + ^ + | + master +------------ + +This operation is not always possible; if you've made changes and the branches +diverged: + +------------ + D---C---B---A origin/master + \ + X---Y master +------------ + +then the fast-forward command will fail. + +In those cases you need to either `git merge`, or `git rebase` in order to +synchronize the two branches. + THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOUR MAY CHANGE. SEE ALSO -------- -linkgit:git-merge[1] +linkgit:git-merge[1], linkgit:git-rebase[1] GIT ---
