With the following example, the available artifact (named `artifact` which is the default if no name is provided) would contain both `world.txt` (`hello`) and `extra-file.txt` (`howdy`).
> **_Warning:_** Be careful when uploading to the same artifact via multiple jobs as artifacts may become corrupted
```yaml
strategy:
matrix:
node-version: [8.x, 10.x, 12.x, 13.x]
steps:
- name: 'Create a file'
run: echo ${{ matrix.node-version }} > my_file.txt
- name: 'Accidently upload to the same artifact via multiple jobs'
uses: 'actions/upload-artifact@v2'
with:
name: my-artifact
path: ${{ github.workspace }}
```
In the above example, four jobs will upload four different files to the same artifact but there will only be one file available when `my-artifact` is downloaded. Each job overwrites what was previously uploaded. To ensure that jobs don't overwrite existing artifacts, use a different name per job.
```yaml
uses: 'actions/upload-artifact@v2'
with:
name: my-artifact ${{ matrix.node-version }}
path: ${{ github.workspace }}
```
### Environment Variables and Tilde Expansion
You can use `~` in the path input as a substitute for `$HOME`. Basic tilde expansion is supported.
