base on Action for checking out a repo [](https://github.com/actions/checkout/actions/workflows/test.yml)
# Checkout V4
This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.
Only a single commit is fetched by default, for the ref/SHA that triggered the workflow. Set `fetch-depth: 0` to fetch all history for all branches and tags. Refer [here](https://docs.github.com/actions/using-workflows/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.
The auth token is persisted in the local git config. This enables your scripts to run authenticated git commands. The token is removed during post-job cleanup. Set `persist-credentials: false` to opt-out.
When Git 2.18 or higher is not in your PATH, falls back to the REST API to download the files.

# Usage
<!-- start usage -->
```yaml
- uses: actions/checkout@v4
with:
# Repository name with owner. For example, actions/checkout
# Default: ${{ github.repository }}
repository: ''
# The branch, tag or SHA to checkout. When checking out the repository that
# triggered a workflow, this defaults to the reference or SHA for that event.
# Otherwise, uses the default branch.
ref: ''
# Personal access token (PAT) used to fetch the repository. The PAT is configured
# with the local git config, which enables your scripts to run authenticated git
# commands. The post-job step removes the PAT.
#
# We recommend using a service account with the least permissions necessary. Also
# when generating a new PAT, select the least scopes necessary.
#
# [Learn more about creating and using encrypted secrets](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets)
#
# Default: ${{ github.token }}
token: ''
# SSH key used to fetch the repository. The SSH key is configured with the local
# git config, which enables your scripts to run authenticated git commands. The
# post-job step removes the SSH key.
#
# We recommend using a service account with the least permissions necessary.

ssh-key: ''
# Known hosts in addition to the user and global host key database. The public SSH
# keys for a host may be obtained using the utility `ssh-keyscan`. For example,
# `ssh-keyscan github.com`. The public key for github.com is always implicitly
# added.
ssh-known-hosts: ''
# Whether to perform strict host key checking. When true, adds the options
# `StrictHostKeyChecking=yes` and `CheckHostIP=no` to the SSH command line. Use
# the input `ssh-known-hosts` to configure additional hosts.
# Default: true
ssh-strict: ''
# The user to use when connecting to the remote SSH host. By default 'git' is
# used.
# Default: git
ssh-user: ''
# Whether to configure the token or SSH key with the local git config
# Default: true
persist-credentials: ''
# Relative path under $GITHUB_WORKSPACE to place the repository
path: ''
# Whether to execute `git clean -ffdx && git reset --hard HEAD` before fetching
# Default: true
clean: ''
# Partially clone against a given filter. Overrides sparse-checkout if set.
# Default: null
filter: ''
# Do a sparse checkout on given patterns. Each pattern should be separated with
# new lines.
# Default: null
sparse-checkout: ''
# Specifies whether to use cone-mode when doing a sparse checkout.
# Default: true
sparse-checkout-cone-mode: ''
# Number of commits to fetch. 0 indicates all history for all branches and tags.
# Default: 1
fetch-depth: ''
# Whether to fetch tags, even if fetch-depth > 0.
# Default: false
fetch-tags: ''
# Whether to show progress status output when fetching.
# Default: true
show-progress: ''
# Whether to download Git-LFS files
# Default: false
lfs: ''
# Whether to checkout submodules: `true` to checkout submodules or `recursive` to
# recursively checkout submodules.
#
# When the `ssh-key` input is not provided, SSH URLs beginning with
# `
[email protected]:` are converted to HTTPS.
#
# Default: false
submodules: ''
# Add repository path as safe.directory for Git global config by running `git
# config --global --add safe.directory <path>`
# Default: true
set-safe-directory: ''
# The base URL for the GitHub instance that you are trying to clone from, will use
# environment defaults to fetch from the same instance that the workflow is
# running from unless specified. Example URLs are https://github.com or
# https://my-ghes-server.example.com

## Fetch only the root files
```yaml
- uses: actions/checkout@v4
with:
sparse-checkout: .
```
## Fetch only the root files and `.github` and `src` folder
```yaml
- uses: actions/checkout@v4
with:
sparse-checkout: |
.github
src
```
## Fetch only a single file
```yaml
- uses: actions/checkout@v4
with:
sparse-checkout: |
README.md
sparse-checkout-cone-mode: false
```
## Fetch all history for all tags and branches
```yaml
- uses: actions/checkout@v4
with:
fetch-depth: 0
```
## Checkout a different branch
```yaml
- uses: actions/checkout@v4
with:
ref: my-branch
```
## Checkout HEAD^
```yaml
- uses: actions/checkout@v4
with:
fetch-depth: 2
- run: git checkout HEAD^
```
## Checkout multiple repos (side by side)
```yaml
- name: Checkout
uses: actions/checkout@v4
with:
path: main
- name: Checkout tools repo
uses: actions/checkout@v4
with:
repository: my-org/my-tools
path: my-tools
```
> - If your secondary repository is private or internal you will need to add the option noted in [Checkout multiple repos (private)](#Checkout-multiple-repos-private)
## Checkout multiple repos (nested)
```yaml
- name: Checkout
uses: actions/checkout@v4
- name: Checkout tools repo
uses: actions/checkout@v4
with:
repository: my-org/my-tools
path: my-tools
```
> - If your secondary repository is private or internal you will need to add the option noted in [Checkout multiple repos (private)](#Checkout-multiple-repos-private)
## Checkout multiple repos (private)
```yaml
- name: Checkout
uses: actions/checkout@v4
with:
path: main
- name: Checkout private tools
uses: actions/checkout@v4
with:
repository: my-org/my-private-tools
token: ${{ secrets.GH_PAT }} # `GH_PAT` is a secret that contains your PAT
path: my-tools
```
> - `${{ github.token }}` is scoped to the current repository, so if you want to checkout a different repository that is private you will need to provide your own [PAT](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).
## Checkout pull request HEAD commit instead of merge commit
```yaml
- uses: actions/checkout@v4
with:
ref: ${{ github.event.pull_request.head.sha }}
```
## Checkout pull request on closed event
```yaml
on:
pull_request:
branches: [main]
types: [opened, synchronize, closed]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
```
## Push a commit using the built-in token
```yaml
on: push
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- run: |
date > generated.txt
# Note: the following account information will not work on GHES
git config user.name "github-actions[bot]"
git config user.email "41898282+github-actions[bot]@users.noreply.github.com"
git add .
git commit -m "generated"
git push
```
*NOTE:* The user email is `{user.id}+{user.login}@users.noreply.github.com`. See users API: https://api.github.com/users/github-actions%5Bbot%5D
## Push a commit to a PR using the built-in token
In a pull request trigger, `ref` is required as GitHub Actions checks out in detached HEAD mode, meaning it doesn’t check out your branch by default.
```yaml
on: pull_request
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
with:
ref: ${{ github.head_ref }}
- run: |
date > generated.txt
# Note: the following account information will not work on GHES
git config user.name "github-actions[bot]"
git config user.email "41898282+github-actions[bot]@users.noreply.github.com"
git add .
git commit -m "generated"
git push
```
*NOTE:* The user email is `{user.id}+{user.login}@users.noreply.github.com`. See users API: https://api.github.com/users/github-actions%5Bbot%5D
