The `git bisect` command in Git is a helpful tool for finding the commit that introduced a bug or issue. It allows you to perform a binary search through the commit history to pinpoint the specific commit where the problem was introduced. The process involves marking specific points in the commit history as "good" or "bad" and using this information to narrow down the range of commits to search.

Here's an overview of how the `git bisect` command works:

1. Start the bisect process: Begin the bisect process by running the following command:

   git bisect start

2. Mark the current commit as "bad": Identify the commit at which the bug is present and mark it as "bad" using the following command:

   git bisect bad

3. Mark a known good commit: Specify a commit known to be free of the bug and mark it as "good". You can provide a commit hash, a branch name, a tag, or any other valid reference to indicate a known good commit:

   git bisect good 

4. Git performs a binary search: Git will automatically check out a commit halfway between the known good and bad commits. It then prompts you to test and determine if the bug is present in that commit. Based on your feedback, Git will mark it as "good" or "bad". 5. Repeat the process: Git will continue performing binary searches, checking out commits based on your feedback, until it finds the exact commit where the bug was introduced. 6. Finish the bisect process: Once the problematic commit has been identified, you can end the bisect process by running the following command:

   git bisect reset

This command returns your repository to the original state, discarding any temporary changes made during the bisect process. Conclusion : The `git bisect` command helps you efficiently identify the commit that introduced a bug, making it easier to analyze, understand, and resolve the issue. It's a powerful tool for debugging and finding the root cause of problems in your codebase.
