When a user presses the tab key within an interactive command-shell, Bash automatically uses command line completion, since beta version 2.04, [87] to match partly typed program names, filenames and variable names. The Bash command-line completion system is very flexible and customizable, and is often packaged with functions that complete ...
In computing, ver (short for version) is a command in various command-line interpreters such as COMMAND.COM, cmd.exe and 4DOS/4NT. It prints the name and version of the operating system, the command shell, or in some implementations the version of other commands. It is roughly equivalent to the Unix command uname.
Command-line completion allows the user to type the first few characters of a command, program, or filename, and press a completion key (normally Tab ↹) to fill in the rest of the item. The user then presses Return or ↵ Enter to run the command or open the file.
Support for command history means that a user can recall a previous command into the command-line editor and edit it before issuing the potentially modified command. Shells that support completion may also be able to directly complete the command from the command history given a partial/initial part of the previous command.
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. [2]
Command-line shells provide a command-line interface (CLI) to the operating system, while graphical shells provide a graphical user interface (GUI). Other possibilities, although not so common, include a voice user interface and various implementations of a text-based user interface (TUI) that are not CLI, such as text-based menu systems. The ...
A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command lines. Command-line interfaces emerged in the mid-1960s, on computer terminals , as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards .
