Git Version Control Cookbook

How it works...

For each commit in the repository, Git will check the content of that commit and run tree-filter. If the filter fails with a non-zero exit code, filter-branch will fail. Therefore, it is important to remember to handle cases where tree-filter might fail. This is the reason why the previous tree-filter checks whether the .credentials file exists, runs the sed command if it does, and otherwise returns true to continue the filter-branch.
