To delete the merge history of a file in Git, you can use the following steps:

  1. Open your Git repository in your preferred Git client or navigate to the repository's directory using the command line.
  2. Make sure you are on the branch where you want to remove the merge history. Use the command git branch to check your current branch and switch branches if needed.
  3. Create a backup branch (optional but recommended) with the current state of the file(s) you want to modify. You can use a command like git branch backup to create a backup branch and preserve the current state for future reference or rollback if needed.
  4. Remove the file(s) from the Git history using the Git filter-branch command. The --tree-filter option can be used to modify the file(s) directly. For example, to delete the merge history of a single file called "filename.ext", use the following command: git filter-branch --tree-filter 'rm -f path/to/filename.ext' -- --all Replace "path/to/filename.ext" with the actual path to the file. The --all option ensures that the operation is applied to all branches of the repository. Note that this command rewrites the Git history, so make sure you have a backup branch or a backup of your repository before proceeding.
  5. Once the filter-branch command has completed, the merge history for the specified file(s) should be removed. You can verify this by checking the commit history using git log or using a Git client with a visual representation of the history.
  6. If you are satisfied with the changes and have verified that the merge history is deleted for the specified file(s), you can remove the backup branch (if created) using git branch -D backup command.


Please note that modifying Git history could potentially cause issues, especially if the repository is being used by others. It is recommended to communicate and coordinate with your team before performing such operations to avoid any conflicts or surprises.
