The word "commandline interface" refers to a type of user interface where a user interacts with a computer system by typing commands rather than using a graphical user interface. The correct spelling of this term is [kəˈmændlaɪn ˈɪntərfeɪs]. The first syllable is pronounced with the schwa sound [ə], followed by the stressed syllable with the vowel sound [æ]. The word "commandline" is written as one word, while "interface" is written as two distinct words.
A command-line interface, often referred to as CLI, is a textual user interface that allows users to interact with a computer program or operating system by entering commands via a command prompt. It is a method of communicating with a computer system by typing text-based commands rather than using a graphical user interface (GUI). A CLI typically presents users with a simple prompt displayed on a command line, awaiting input.
In a command-line interface, users can execute various commands to perform specific tasks or access system functions. These commands may include file management, process control, system configuration, network administration, and software execution, among others. Users interact with the CLI by typing commands and pressing Enter or Return to execute them. The output of these commands is displayed on the same command line, providing users with feedback or requested information.
Command-line interfaces are often used by advanced or technical users who prefer the efficiency and power of text-based commands. They are commonly utilized in programming, system administration, and computer networking tasks. While they may require users to learn specific command syntax and options, command-line interfaces are highly flexible and can often perform complex operations more quickly than their graphical counterparts. Overall, a command-line interface serves as a direct and efficient means of interacting with a computer system, focusing on the input of textual commands to control and manage various aspects.
The word "commandline" can be broken down into two parts: "command" and "line".
The term "command" comes from Old French "comander" (modern French "commander") which means "to order or direct". It ultimately derives from Latin "commendare", meaning "to entrust, commit to one's charge".
The term "line" originated from Middle English "line" which meant "a cord or rope used for measuring". It has its roots in the Latin word "linea", meaning "a linen thread or string".
The word "interface" comes from the Latin prefix "inter-" meaning "between" and the Latin noun "facies" meaning "face". Thus, "interface" refers to a connecting point or boundary between two entities.
