Command (computing)In computing, a command is a high-level instruction received via an external interface that directs the behavior of a computer program. Commonly, commands are sent to a program via a command-line interface, a script, a network protocol, or as an event triggered in a graphical user interface. Many commands support arguments to specify input and to modify default behavior. Terminology and syntax varies but there are notable common approaches.Command patternIn object-oriented programming, the command pattern is a behavioral design pattern in which an object is used to encapsulate all information needed to perform an action or trigger an event at a later time. This information includes the method name, the object that owns the method and values for the method parameters. Four terms always associated with the command pattern are command, receiver, invoker and client.
Command keyThe Command key (sometimes abbreviated as Cmd key), ⌘, formerly also known as the Apple key or open Apple key, is a modifier key present on Apple keyboards. The Command key's purpose is to allow the user to enter keyboard commands in applications and in the system. An "extended" Macintosh keyboard—the most common type—has two command keys, one on each side of the space bar; some compact keyboards have one only on the left.
Command (military formation)A command in military terminology is an organisational unit for which a military commander is responsible. Commands, sometimes called units or formations, form the building blocks of a military. A commander is normally specifically appointed to the role in order to provide a legal framework for the authority bestowed.
COMMAND.COMCOMMAND.COM is the default command-line interpreter for MS-DOS, Windows 95, Windows 98 and Windows Me. In the case of DOS, it is the default user interface as well. It has an additional role as the usual first program run after boot (init process). As a shell, COMMAND.COM has two distinct modes of operation: interactive mode and batch mode.Command (Unix)command is a shell command for executing a command without invoking a function or alias that has the same name. The command line arguments consist of an inner command line to executed. If the first argument is the name of a function or alias as well as the name of a command, then normally the function or alias takes precedence, but when passed as an argument to command the inner command is invoked instead of the function.
Command and controlCommand and control (abbr. C2) is a "set of organizational and technical attributes and processes ...

Command responsibilityIn the practice of international law, command responsibility (also superior responsibility) is the legal doctrine of hierarchical accountability for war crimes, whereby a commanding officer (military) and a superior officer (civil) are legally responsible for the war crimes and the crimes against humanity committed by their subordinates; thus, a commanding officer always is accountable for the acts of commission and the acts of omission of their soldiers.
Command hierarchyA command hierarchy or chain of command is a group of people who carry out orders based on others' authority within the group. Certain aspects of a command hierarchy tend to be similar, including rank, unity of command, and strict accountability. Command hierarchies are used in the military and other organizations. Systemic biases may arise in homogenous groups of command.
