Many beginners are frightened by a black window with a flashing cursor. It seems that this is something ancient and incomprehensible. But in fact, it is the superpower of a programmer.
Command line (aka Terminal or CMD) is a tool with which you communicate directly with the system. Sounds cool? You bet! 😎
manage files and folders without a mouse,
run scripts and programs,
work with Git, Python, Node.js, Docker and other tools,
as well as automate the routine.

Command line in real life
You'll be surprised, but almost all developers use the terminal every day. It is needed to run servers, install packages, work with Git, automate tasks and even deploy projects. By mastering it, you will become not just a user, but the owner of your computer 💪
If you want to master the terminal from scratch, start with small steps. Enter a couple of new commands every day. In a week you won't be able to do without it!
And in the application Code There are interactive lessons where you learn to write code directly with practice. We also analyze how to use the command line when working with Git and Python.
We also have an active Telegram channel where we discuss cool ideas, share experiences and analyze tasks together — learning becomes not only useful, but also fun.
Do you remember your first command in the terminal? Write in the comments what it was — ls, cd or rm wrong 😅
