# Passing ENV variable in script

### Passing ENV variable in script

* To pass variable in script you will have to define it in the ENV first then pass the ENV variable in the script

```yaml
name: Backup Nextcloud

on:
  schedule:
    # Runs "At 02:01" (see https://crontab.guru)
    - cron: '1 2 * * *'

jobs:
  ssh:
    name: Backup Nextcloud
  
    runs-on: [self-hosted, linux]

    env:
    # This is used to define the environment
      SYSTEM_USER: ${{ secrets.SYSTEM_USER }}
      NEXTCLOUD_SCRIPT_PATH: ${{ secrets.NEXTCLOUD_SCRIPT_PATH }}

    steps:
    - name: SSH and execute Backup Script

      with:
        host: ${{ secrets.HOSTNAME }}
        username: ${{ secrets.USERNAME }}
        key: ${{ secrets.SSH_PRIVATE_KEY }}
        
        # This is used to pass the variables in the script

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.arkannis.net/devops/github-actions/passing-env-variable-in-script.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
