See also Why is a Virtual Terminal “virtual”, and what/why/where is the “real” Terminal?. On some systems, such as Linux and FreeBSD, the console appears as several terminals (ttys) (special key combinations switch between these terminals) just to confuse matters, the name given to each particular terminal can be “console”, ”virtual console”, ”virtual terminal”, and other variations. The console appears to the operating system as a (kernel-implemented) terminals. ConsoleĪ console is generally a terminal in the physical sense that is by some definition the primary terminal directly connected to a machine. For example an X terminal is a kind of thin client, a special-purpose computer whose only purpose is to drive a keyboard, display, mouse and occasionally other human interaction peripherals, with the actual applications running on another, more powerful computer. The word terminal can also have a more traditional meaning of a device through which one interacts with a computer, typically with a keyboard and display.

Some terminals are provided by the kernel on behalf of a hardware device, for example with the input coming from the keyboard and the output going to a text mode screen, or with the input and output transmitted over a serial line. In unix terminology, a terminal is a particular kind of device file which implements a number of additional commands ( ioctls) beyond read and write. Very early in unix history, electronic keyboards and displays became the norm for terminals. The name “terminal” came from the electronic point of view, and the name “console” from the furniture point of view. Originally, they meant a piece of equipment through which you could interact with a computer: in the early days of unix, that meant a teleprinter-style device resembling a typewriter, sometimes called a teletypewriter, or “tty” in shorthand. terminal = text input/output environmentĬonsole and terminal are closely related.

Available options are ansi, dtterm, nsterm, rxvt, vt52, vt100, vt102, xterm, xterm-16color and xterm-256color, which differ from the OS X 10.5 (Leopard) choices by dropping the xterm-color and adding xterm-16color and xterm-256color. The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) and later offers choices for values of the TERM environment variable. The user can choose other shells available with macOS, such as the KornShell, tcsh, and bash. Īs a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command-line interface to the operating system when used in conjunction with a Unix shell, such as zsh (the default shell in macOS Catalina ). Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS. Terminal ( Terminal.app) is the terminal emulator included in the macOS operating system by Apple.
