![]() ![]() The Git history reflects the change: $ git log -oneline ![]() Note that it also assigns that commit a new id, since it deleted the old commit and created a new one in its place. This changes the commit message on the most recent commit from "something css related" (as seen in the git log above) to "add styling to main page". In this case we can use git commit -amend to simply update the commit message: $ git commit -amend -m "add styling to main page" Let's say we committed the right files, but we messed up the commit message. Let’s clean up this Git commit history! $ git commit -amendįirst we'll learn how to modify the most recent commit. There are also two consecutive commits about the same feature. We can see that this project contains some poorly-worded commits. And we can add the -oneline flag to display the history in an easier to read format: $ git log -oneline We can see a project's commit history with the git log command. In this lesson, we'll cover several ways to make changes to your Git commit history. However, in some circumstances it is necessary to modify your local commit history (that is, commits that exist locally on your machine, but have not been pushed to Github yet) before pushing your repository. For that reason, you should not modify commit history on a branch others are also working on. If others are working on the same branch they will still have your old commits when they pull down any changes, and will be asked to merge your rewritten commits with your new commits. This is especially true if you are working collaboratively with others: If you modify an existing commit, it actually removes the old commit from the project and makes a new one in its place. Thankfully, Git offers several options to re-write commits.īut first, note that we need to be very careful when modifying Git history. However, even the most careful developers can make mistakes. We always want to include clear and detailed messages with our commits. ![]()
