What are githooks explained in 5 minutes

git hooks are scripts that can be triggered at certain points in the git workflow. they provide a way to automate tasks or enforce certain rules before or after specific git actions like committing, pushing, and merging. git hooks are stored in the `.git/hooks` directory of a git repository and are named according to the action they are associated with.

here are some commonly used git hooks:

1. **pre-commit**: this hook is triggered before a commit is made. it can be used to run pre-commit checks such as code linting, formatting, or testing.

2. **prepare-commit-msg**: this hook is triggered before the commit message editor is opened. it can be used to modify the commit message or add additional information.

3. **post-commit**: this hook is triggered after a commit is made. it can be used to trigger notifications or perform cleanup tasks.

4. **pre-push**: this hook is triggered before a push is executed. it can be used to run pre-push checks or prevent specific code from being pushed to the remote repository.

5. **pre-receive**: this hook is triggered on the remote repository before any references are updated. it can be used to enforce server-side rules or reject certain changes.

to create a git hook, you need to create a script in the `.git/hooks` directory and make it executable. here's an example of a simple pre-commit hook that runs a code linter before allowing a commit:

1. navigate to your git repository:

2. create a new file named `pre-commit` in the `.git/hooks` directory:

3. make the script executable:

4. edit the `pre-commit` script with your preferred text editor:

5. add the following code to the `pre-commit` script:

6. save and exit the text editor.

now, every time you try to make a commit in this repository, the `pre-commit` hook will run the specified code linter. if the linter fails, the commit will be aborted, and you'll need to fix the issues before trying again.

remember that git hooks are specific to each local repository and ar ...
