Removing a file from the latest Git commit can be done in a few simple steps. Here are two possible approaches:
Approach 1: Interactive Rebase
1. Start by opening a terminal or command prompt and navigating to the repository directory.
2. Make sure you are on the branch that contains the commit from which you want to remove the file.
3. Run the following command to initiate an interactive rebase:
git rebase -i HEAD~n
Replace n with the number of commits you want to include in the interactive rebase. For example, if you want to include the last 5 commits, use git rebase -i HEAD~5.
4. An editor will open with a list of commits. Find the commit that contains the file you want to remove and change the command from pick to edit for that specific commit.
5. Save and close the file to proceed with the rebase.
6. Git will now stop at the commit you want to edit. Run the following command to remove the file from the commit:
git rm path/to/file
Replace path/to/file with the actual path to the file you want to remove.
7. Continue the rebase by running the following command:
git rebase --continue
8. Git will apply the remaining commits and remove the file from the latest commit.

Approach 2: Amend the Commit
1. Open a terminal or command prompt and navigate to the repository directory.
2. Make sure you are on the branch that contains the commit from which you want to remove the file.
3. Run the following command to open the commit for editing:
git rebase -i HEAD~n
Replace n with the number of commits you want to include in the interactive rebase. For example, if you want to include the last 5 commits, use git rebase -i HEAD~5.
4. An editor will open with a list of commits. Find the commit that contains the file you want to remove and change the command from pick to edit for that specific commit.
5. Save and close the file to proceed with the rebase.
6. Git will now stop at the commit you want to edit. Run the following command to remove the file from the commit:
git rm path/to/file
Replace path/to/file with the actual path to the file you want to remove.
7. Amend the commit by running the following command:
git commit --amend --no-edit
8. Git will update the commit and remove the file.
In both approaches, you can also use the git filter-branch command to remove a file from multiple commits or an entire branch. However, this command is more advanced and should be used with caution. It’s recommended to consult the official Git documentation or seek expert advice before using git filter-branch.
Best Practices
– Before modifying Git history, make sure to create a backup of your repository or work on a separate branch to avoid losing any important changes.
– If you are working in a team, it’s important to communicate any changes in Git history to your collaborators, especially if the commit has already been pushed to a remote repository.
– Use interactive rebasing or commit amending sparingly, as frequent history modifications can make the repository history difficult to follow and cause confusion.
Alternative Ideas
– Instead of removing a file from a commit, you can also use the git revert command to create a new commit that undoes the changes made by a previous commit. This approach keeps the original commit intact and adds a new commit that effectively removes the changes.
– If you want to remove a file from all commits in a repository, you can use the git filter-branch command with the --tree-filter option. This command allows you to modify the repository’s history by applying a specified command to each commit.
For more information and detailed examples, refer to the official Git documentation on the git-rebase and git-filter-branch commands.
