To me it happens quite frequently that I have several local commits (in a private Git checkout), of which I only want to push some upstream. One option is to use cherry-pick and extra branches. Today I found a more straightforward solution:
git push origin $SHA_OF_LAST_COMMIT:master
Git only pushes the commit specified by it’s hash sum and all it’s ancestors (on the current local branch) that aren’t yet upstream (on the master branch of the origin remote). Finally, git rebase -i can be used to consecutively rearrange the (local) commits you want to push. Much easier, no?
