```sh-session
$ sfp sandbox:update -o MyDevHub -n my-sandbox
$ sfp sandbox:update -o MyDevHub -f config/sandbox-def.json
```

### Sandbox Definition File

If using a definition file, create a JSON file (default location: `config/sandbox-def.json`) with the following structure:

```json
{
  "sandboxName": "MySandbox",
  "description": "Updated sandbox description",
  "apexClassId": "01p...",
  "autoActivate": true,
  "copyChatter": true,
  "historyDays": 0,
  "licenseType": "DEVELOPER",
  "templateId": "0TT..."
}
```

Note: When using a definition file, the `--name` flag is ignored.
