Question: System Settings can be run from the launcher (pinned by default), the Dash, or the power cog. But what command would I enter in a terminal window if I want to run it from there?

Answer: 
```
gnome-control-center

```

**Note**: for versions between 14.04 and 17.04 (when Unity was used instead of GNOME), the command is `unity-control-center`.
For [Ubuntu Mate](https://ubuntu-mate.org/) the command is `mate-control-center`.
