This can also be thought of as the point at which two commits were merged. Use `git bisect` treating the latest commit as the “bad” commit and one of the two commits as the “good” commit. Then check ancestry using: ```sh #!/bin/sh ! git merge-base --is-ancestor <first> @ || ! git merge-base --is-ancestor <second> @ ``` > [!tip] > Run this script using > > ```sh > git bisect run command > ```
