How Can I Remove a File from Git History Without Deleting It Locally?

Hey there! 👋

You’ll want to untrack the file while still keeping it in your local working directory. Run this command:

git rm --cached path/to/your/file

This removes the file from the Git index (the staging area) but leaves it untouched in your local file system. More details on the git rm command can be found in the official Git documentation.

To prevent Git from tracking this file in the future, add it to your .gitignore file:

echo "path/to/your/file" >> .gitignore

Learn more about how .gitignore works and its syntax here.

Now commit this change to remove the file from being tracked:

git add .gitignore
git commit -m "Stop tracking large/sensitive file"

If you want to remove the file from previous commits (history), you can use the filter-branch or BFG Repo-Cleaner. Here’s an example with filter-branch:

git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch path/to/your/file' --prune-empty --tag-name-filter cat -- --all

This will remove the file from all past commits. Be cautious with this step as it rewrites history. More on rewriting Git history.

After rewriting history, push the changes:

git push origin --force

Again, force-pushing can overwrite shared history, so be careful. Here’s more info on force-push.
