You Don't Need GUI

It's for noobs :)

Graphical user interfaces are super friendly to computer users. They were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs).

However, they often require more resources, are less powerful and hard to automate via scripting.

As a computer expert, we want to be more efficient and do our jobs better. We know that command words may not be easily discoverable or mnemonic, so we try to list some common tasks that you might tempt to do in GUI.
