# \[This] device pointer

On each device there has to be a `this` symlink:

```bash
~/.dmt/user/devices/this → ./[device_name]
```

{% hint style="info" %}
**This device pointer** tells the DMT ENGINE to behave in this particular device-specific way.
{% endhint %}

### How to set or change the device pointer?

```bash
dmt device select
```
