A little overview about terminals

As a developer, you must have gotten your hands dirty with terminal emulators at some point in your career. They are powerful tools that allow you to interact with your operating system and run commands from the command line. You might think that it is just text in a black box, but it’s much more than that.

You see, in the early days of computing, a computer was literally a green/white text on a black background. This you can say is a true computer, you give some input, and you get some output. But as time went on, we moved on from that and started using graphical user interfaces (GUIs). GUIs allowed us to interact with our computers using a mouse and a keyboard, but they were not as powerful as terminal emulators. Behind the scenes, a GUI is just executing commands that we used to enter manually in the terminal.
