The pre-commit install command is used to set up the pre-commit hook for a Git repository.

In Git, a hook is a script that runs automatically before or after certain Git events, such as committing code. The pre-commit hook, as the name suggests, is executed before a commit is made. It allows you to perform various checks or actions on the code being committed and can be used to enforce certain guidelines or conventions.

The pre-commit install command is typically run in the root directory of a Git repository. When executed, it looks for a configuration file called .pre-commit-config.yaml in the repository. This file specifies which hooks should be enabled and which scripts should be executed when the hooks are triggered.

Once the pre-commit install command is successfully run, it creates a symbolic link or copies the necessary files to the .git/hooks/ directory of the repository. This enables the pre-commit hook and ensures that it runs whenever a commit is made in that repository.

By setting up the pre-commit hook, you can automate code checks, formatting, linting, or any other actions to maintain code quality and consistency before the changes are committed.
