What does CLI mean?
CLI means Command Line Interface: a text-based way to interact with a computer by typing commands instead of clicking buttons.
It’s commonly used for system administration, software development, and automation because it can be fast and precise.
Most people use a mouse to click on icons. This is called a GUI (Graphical User Interface). While a GUI is pretty, a CLI is much more powerful for specific tasks:
- Save time: You can move, rename, or delete thousands of files with one line of text. Clicking them one by one would take hours.
- Automate tasks: You can write a list of commands once and tell the computer to run them every day.
- Talk to servers: Most computers that power the internet (servers) do not have screens or mice. You must use a CLI to manage them.
- Use less power: Because there are no heavy graphics, the CLI makes your computer run faster and uses less battery.
- Developer tools: Most modern coding tools only work inside a CLI.
