I actually once pushed with --force and .git repository and got scolded by Linus BIG TIME. In general this will create a lot of problems for other people. A simple answer is “Don’t do it”.
I see others gave the recipe for doing so anyway, so I won’t repeat them here. But here is a tip to recover from the situation after you have pushed out the amended commit with –force (or +master).
- Use
git reflogto find the old commit that you amended (call itold, and we’ll call the new commit you created by amendingnew). - Create a merge between
oldandnew, recording the tree ofnew, likegit checkout new && git merge -s ours old. - Merge that to your master with
git merge master - Update your master with the result with
git push . HEAD:master - Push the result out.
Then people who were unfortunate enough to have based their work on the commit you obliterated by amending and forcing a push will see the resulting merge will see that you favor new over old. Their later merges will not see the conflicts between old and new that resulted from your amending, so they do not have to suffer.
