Essential System Utilities: WTF – terminal dashboard

In Operation

Here’s an image of WTF with a default configuration.

As the image shows, we’re presented with a number of widgets showing various information. The left panel shows a text file (it’s the config.yml to configure the program). The other panels are showing time clocks, a news feed, IP information (which we redacted some of the information), and battery information.

The widgets that you see on the screen are displayed using modules. The real power of WTF is these modules. They are chunks of functionality that let you tailor the information to your precise requirements.  A module is a discrete unit of functionality that extracts data from a source and packages that data for display.

Modules are added and configured by including specific lines of text in your config.yml file. In the image below, we’re starting to configure WTF. We’ve taken one of the sample configs available from the project’s GitHub repository, and added a feed reader to our RSS feed which is available at and positioned it in the top right hand corner.

There are many modules available which are easily added by inserting specific code in the config file. That file lets us define where each module appears, defines the number of rows and columns and the widget height and width.
