What are some common use cases for Git hooks?

Git hooks are scripts that run automatically at certain points in the Git workflow. Common use cases include:

1. Pre-commit hooks: Validate code before committing, such as running linters or tests.
2. Post-commit hooks: Notify team members or trigger CI/CD pipelines after a commit.
3. Pre-push hooks: Prevent pushing code that doesn't meet certain criteria, like failing tests.
4. Post-receive hooks: Deploy code to production after it has been pushed to the repository.

Can you give me an example of a pre-commit hook?

Sure! A common pre-commit hook is one that runs a linter to check for code style issues. You can create a script that runs your linter and exits with a non-zero status if any issues are found, preventing the commit.

How do I set up a Git hook?

To set up a Git hook, navigate to your repository's .git/hooks directory. You'll find sample hook scripts there. You can rename one of them (like pre-commit.sample to pre-commit) and make it executable. Then, add your custom script logic to that file.

Are there any built-in hooks I should know about?

Yes, Git provides several built-in hooks, including:

• pre-commit
• commit-msg
• post-commit
• pre-push
• post-receive Each serves a specific purpose in the workflow.
