Final answer:
To amend a commit in Git, first stage any additional changes, then run the command 'git commit --amend'. This replaces the previous commit with a new commit that includes the newly staged changes.
Step-by-step explanation:
To amend a commit in Git after making additional changes, you can use the following steps:
- First, make the changes you want to include in the previous commit.
- Stage these changes for commit by using git add.
- After staging the changes, amend the previous commit with the command git commit --amend.
This will open your default text editor where you can modify the commit message if necessary. When you save and close the editor, Git will create a new commit that replaces the old one, including the changes you've just staged.
Please note that amending a commit that has already been pushed to a shared repository can cause issues for others since it rewrites the Git history. If the commit has been pushed, you should only amend when you are certain no one else has based their work on this commit, or you are prepared to coordinate with your team regarding the change.
