    • Command-line completion (also tab completion) is a common feature of command-line interpreters, in which the program automatically fills in partially typed commands.

      Command line interpreters are programs that allow a user to interact with the underlying operating system by typing commands at a command prompt using a command line interface (CLI), in contrast to pointing and clicking a mouse in a Graphical User Interface (GUI). Command-line completion allows the user to type the first few characters of a command, program, or filename, and press a completion key (normally ) to fill in the rest of the item. The user then presses or to run the command or open the file.

      Command-line completion is useful in several ways, as illustrated by the animation accompanying this article. Commonly accessed commands, especially ones with long names, require fewer keystrokes to reach. Commands with long or difficult to spell filenames can be entered by typing the first few characters and pressing a completion key, which completes the command or filename. In the case of multiple possible completions, some command-line interpreters, especially Unix shells, will list all possible completions beginning with those few characters. The user can type more characters and press again to see a new, narrowed-down list if the typed characters are still ambiguous, or else complete the command/filename with a trailing space. An alternate form of completion rotates through all matching results when the input is ambiguous.

      Completable elements may include commands, arguments, file names and other entities, depending on the specific interpreter and its configuration. Command-line completion generally only works in interactive mode. That is, it cannot be invoked to complete partially typed commands in scripts or batch files, even if the completion is unambiguous. The name tab completion comes from the fact that command-line completion is often invoked by pressing the tab key.
