CUI stands for Command-line User Interface, also called Command-line Interface (CLI), which is a type of user interface that allows users to interact with a computer by typing commands into a text-based interface. Developers and system administrators typically use CUI applications to perform tasks that are not easily accomplished through a graphical user interface (GUI).
Examples of CUI applications include:
Shells: These command-line interfaces provide users with a prompt to enter commands. Examples include the Windows Command Prompt, the MacOS Terminal, and the Linux Bash shell.
Text editors, such as Vim and Nano, are used to create and edit text files.
Version control systems: These are programs that track changes in software projects, such as Git and Mercurial.
Package managers: These programs manage software packages, such as apt-get and yum.
Developers and system administrators often prefer CUI applications because they allow them to perform tasks quickly and easily and can be automated through scripting. Additionally, CUI applications can be controlled remotely, which helps manage servers and other remote systems.
However, CUI applications are less user-friendly than GUI applications, making them more difficult for non-technical users to understand and use.
