# git bisect
> Use binary search to find the commit that introduced a bug.
> Git automatically jumps back and forth in the commit graph to progressively narrow down the faulty commit.
- Start a bisect session on a commit range bounded by a known buggy commit, and a known clean (typically older) one:
`git bisect start {{bad_commit}} {{good_commit}}`
- For each commit that `git bisect` selects, mark it as "bad" or "good" after testing it for the issue:
`git bisect {{good|bad}}`
- After `git bisect` pinpoints the faulty commit, end the bisect session and return to the previous branch:
`git bisect reset`
- Skip a commit during a bisect (e.g. one that fails the tests due to a different issue):
`git bisect skip`
