A command language is a domain-specific interpreted language; a common example of a command language are shell or batch programming languages. These languages can be used directly at the command line, but can also automate tasks that would normally be performed manually at the command line. They share this domain - lightweight automation - with scripting languages, though a command language usually has stronger coupling to the underlying operating system. Command languages often have either very simple grammars or syntaxes very close to natural language, to shallow the learning curve, as with many other domain-specific languages.
Famous quotes containing the words command and/or language:
“There are confessable agonies, sufferings of which one can positively be proud. Of bereavement, of parting, of the sense of sin and the fear of death the poets have eloquently spoken. They command the world’s sympathy. But there are also discreditable anguishes, no less excruciating than the others, but of which the sufferer dare not, cannot speak. The anguish of thwarted desire, for example.”
—Aldous Huxley (1894–1963)
“Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second and you can hop from one place to another. It’s a language made of image. And in the real cinema, every object and every light means something, as in a dream.”
—Frederico Fellini (1920–1993)
