Multiple Hosts

```diff
  - name: multiple host
    uses: appleboy/ssh-action@master
    with:
-     host: "foo.com"
+     host: "foo.com,bar.com"
      username: ${{ secrets.USERNAME }}
      key: ${{ secrets.KEY }}
      port: ${{ secrets.PORT }}
      script: |
        whoami
        ls -al
```

Pass environment variable to shell script

```diff
  - name: pass environment
    uses: appleboy/ssh-action@master
+   env:
+     FOO: "BAR"
    with:
      host: ${{ secrets.HOST }}
      username: ${{ secrets.USERNAME }}
      key: ${{ secrets.KEY }}
      port: ${{ secrets.PORT }}
+     envs: FOO
      script: |
        echo "I am $FOO"
        echo "I am $BAR"

Stop script after first failure. ex: missing `abc` folder

```diff
  - name: stop script if command error

    with:
      host: ${{ secrets.HOST }}
      username: ${{ secrets.USERNAME }}
      key: ${{ secrets.KEY }}
      port: ${{ secrets.PORT }}
+     script_stop: true
      script: |
        mkdir abc/def
