# Pre-commit

## TL;DR

```sh
# generate a very basic configuration
pre-commit sample-config > .pre-commit-config.yaml

# manually run checks
pre-commit run --all-files
pre-commit run ansible-lint --files ansible/

# automatically run checks at every commit
pre-commit install

# update all hooks to the latest version
pre-commit autoupdate

# skip check on commit
SKIP=flake8 git commit -m "foo"
```

```yaml
---
# File .pre-commit-config.yaml
# See https://pre-commit.com for more information
# See https://pre-commit.com/hooks.html for more hooks
