# major sandbox

> Commands that run inside a Major sandbox.

<Warning>
  `major sandbox` commands only work when run inside a Major sandbox. On a locally installed CLI, every `major sandbox` subcommand fails.
</Warning>

`major sandbox` groups commands that act on the Major sandbox the CLI is running in. The `major` CLI is preinstalled in sandboxes, so you can run these from a sandbox shell.

## major sandbox upload-url

Get a single-use URL that uploads one file into the sandbox at the given path. The command prints the URL, when it expires, and a `curl` command to upload with.

```bash theme={null}
major sandbox upload-url --path <path> [flags]
```

| Flag | Description |
| - | - |
| `--path` | Destination path relative to the sandbox workspace root, for example `public/logo.png`. Required. |
| `--json` | Print one JSON result. |

```bash theme={null}
major sandbox upload-url --path public/logo.png
curl -T logo.png '<upload-url>'
```
