Command Line
Command line interface (or CLI) is an interface which accepts commands from the user, similar to Windows Command Prompt or Linux Terminal. Check also Text_UI.
Implementation
To implement a minimal CLI, you need at least:
- Access to video memory
- Keyboard driver
- String input and comparison
- Some functions to execute on commands
Because of their ease of implementation, CLI's are popular in hobby OS projects.
