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.

Advantages

• Speed and control
• Less resources needed
• Scripts to automate tasks
• No need for mouse devices and drivers

Disadvantages

• Hard for beginner users
• No multitasking
