This commit is provided only to document a correction to a previous commit message. This commit has no substantive code change. In the future, if you need to search through a git log for a feature keyword, the original (erroneous) commit may not appear because the wrong keyword was used in that original commit (the original typo) - however, the keyword will appear in the errata commit which will then point you to the original commit that had the typo. This type of thing so rarely happens that simply documenting the mistake is good enough. It's certainly easier and safer than rebasing, it doesn't modify true history, and it keeps the branch tree clean (using amend is also a good choice if you are correcting the most recent commit, but an errata commit may be a good choice for older commits). An errata commit is a commit with no substantive code changes but an important commit message - for example, add one space character to your readme file and commit that change with the important commit message, or use the git option -allow-empty. you might want to do git push -f to update the remote.Īnother option is to create an additional "errata commit" (and push) which references the commit object that contains the error - the new errata commit also provides the correction. Step4: After all commits msgs are updated. Update the commit msg as you like, then save and close the editor. Step3: Git will pop up another editor for every revision you put r before. from the default vi to nano), run: GIT_EDITOR=nano git rebase -i HEAD~n If you want to change the text editor used for the interactive session (e.g. Note that if you edit your rebase 'plan' yet it doesn't begin the process of letting you rename the files, run: git rebase -continue Don't bother changing the commit message here, it will be ignored. Step2: Change pick to r for those commits that you want to update the message. Git will pop up an editor to handle those commits, notice this command: # r, reword = use commit, but edit the commit message if you want to change a commit message 3 commits back, do git rebase -i HEAD~3) Step1: git rebase -i HEAD~n to do interactive rebase for the last n commits affected. To edit a commit other than the most recent: This is why -force-with-lease is somewhat safer. If you don't think you're destroying data, then stay away from -force. So think of -force as "I want to destroy data, and I know for sure what data is being destroyed." But when the destroyed data is committed, you can often recover old commits from the reflog-the data is actually orphaned instead of destroyed (although orphaned commits are periodically deleted). The destroyed data is really just the old commit message, but -force doesn't know that, and will happily delete other data too. If you have changes to the branch, those changes will be destroyed. Git reset -hard origin/master # Loses local commitsīe careful when using reset -hard. If your default push setting is "matching", then you may destroy changes on several branches at the same time.Īnyone who already pulled will now get an error message, and they will need to update (assuming they aren't making any changes themselves) by doing something like this: git fetch origin If you don't specify the branch explicitly, Git will use the default push settings. The -force-with-lease option is the safest, because it will abort if there are any upstream changes ( If someone else pushed changes to the same branch, you probably want to avoid destroying those changes. (You can use -m if you want to wipe out the old message and use a new one.) PushingĪnd then when you push, do this: git push -force-with-lease This brings up the editor with the last commit message and lets you edit the message. If it is the most recent commit, you can simply do this: git commit -amend
