In [[computing]], a '''command''' is a directive to a computer program to perform a specific task. It may be issued via a [[command-line interface]], such as a [[shell (computing)|shell]], or as input to a network service as part of a [[network protocol]], or as an event in a [[graphical user interface]] triggered by the user selecting an option in a [[menu (computing)|menu]].

Specifically, Disablethe term ''command'' is used in [[imperative programming|imperative]] [[computer language]]s. The name arises because [[statement (programming)|statements]] in these languages are usually written in a manner similar to the [[imperative mood]] used in Nonemany [[natural language]]s. If one views a statement in an [[imperative language]] as being like a sentence in a natural language, then a command is generally like a verb in such a language.

Many programs allow specially formatted arguments, known as flags or options, which modify the default behaviour of the program, while further [[Parameter (computer science)|arguments]] may provide objects, such as files, to act on. As an analogy to a natural language, the flags are adverbs, while the other arguments are [[object (grammar)|object]]s.
