title: "wendy device rename"
description: "Rename a device in Wendy Cloud and set its mDNS hostname"
---

## Syntax

```sh
wendy device rename [name] [flags]
```

## Examples

```sh
wendy device rename --help
```

## Arguments

Argument notation from the CLI: `[name]`. Angle brackets mark required values; square brackets mark optional values. See Details for command-specific validation.

## Flags

Flags below include inherited options. Types and defaults come from the CLI source. An empty default means no value is configured.

| Flag | Type | Default | Description |
| --- | --- | --- | --- |
| `--cloud-grpc` | string | (empty) | Cloud gRPC endpoint to use (defaults to the device's enrolled cloud host) |
| `--device` | string | (empty) | Target device hostname; `wendy run` accepts a comma-separated list to deploy one build to several devices (needs a remote build host and --detach). Defaults to $WENDY_DEVICE, then the saved default device |
| `--json` | bool | `false` | Output in JSON format |

## Output

Output depends on the operation and selected target. [Command behavior and detailed examples](../../../../advanced/clients/wendy-cli/commands/device/rename/).

## JSON output

The global `--json` option requests machine-readable output. The CLI also selects JSON mode when no interactive terminal is attached. Support and payloads are command-specific; this flag does not guarantee a single JSON document for commands that stream logs or invoke build tools. Consult Details before parsing command output.

## Exit codes

The CLI entry point returns `0` on success and for its user-cancelled or default-cleared results. Other returned errors exit with `1` and print a diagnostic to stderr. Some operations may terminate through subprocess or signal handling; do not infer application health from the CLI exit code alone.

## Common errors

Check argument values and flag combinations against the synopsis above. For discovery, build, port, and readiness failures, see [deployment troubleshooting](../../../../errors/). Command-specific constraints are in Details.

## Details

Renames a device in two places: its asset name in Wendy Cloud and its hostname (and mDNS '.local' name) on the device itself. A single name is applied to both. The hostname is set literally — no 'wendyos-' prefix is added — though the interactive prompt is prepopulated with 'wendyos-' as a starting point.

The name must be a valid DNS label: it starts with a lowercase letter, contains only lowercase letters, digits, and hyphens, does not end with a hyphen, and is at most 63 characters.
