How to remove old committed changes in git?

To remove old committed changes in Git, you can use the git rebase command. Here are the steps to remove old committed changes in Git:

1. Open your terminal and navigate to the repository where you want to remove the old committed changes.
2. Use the command git log to see the commit history and find the commit hash of the commit you want to remove.
3. Use the command git rebase -i HEAD~n where 'n' is the number of commits you want to go back. For example, if you want to remove the last 3 commits, use git rebase -i HEAD~3.
4. This will open an interactive rebase editor where you can choose the commits you want to keep, squash, or remove. Simply delete the lines corresponding to the commits you want to remove.
5. Save and close the editor, Git will then reapply the remaining commits on top of the new branch.
6. If there are any conflicts during the rebase process, resolve them and continue the rebase by using git rebase --continue.
7. Once the rebase is complete, check the commit history using git log to ensure that the old commits have been removed.

Please note that removing old committed changes using git rebase can rewrite history and potentially cause issues for collaborators. Make sure to communicate with your team before making any changes to Git history.
