BFG supports various commands for different cleanup operations. Some common commands include:

  • Delete Files: Removes files matching a specified pattern.
  • Delete All Large Files: Removes files larger than a specified size.

Example command to delete all files larger than 100MB:

“`bash
java -jar bfg.jar –strip-blobs-bigger-than 100M my-repo.git
“`

Cleaning Up the Repository

After running BFG, it’s essential to clean up and push the changes back to your remote repository:

  1. Navigate to your cloned repository directory:

“`bash
cd my-repo.git
“`

  1. Run the following command to clean up your repository:

“`bash
git reflog expire –expire=now –all
git gc –prune=now –aggressive
“`

  1. Finally, push your changes to the remote repository:

“`bash
git push –force
“`

Verifying Changes

To ensure that BFG has successfully removed the specified files, you can check the repository’s history:
