A scripting or script language is a programming language for a special run-time environment that automates the execution of tasks; [1] the tasks could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted , rather than compiled. Primitives are usually the elementary tasks or API calls [ clarification needed ] , and the language allows them to be combined into more programs. Environments that can be automated through scripting include software applications , web pages within a web browser , usage of the shells of operating systems OS , embedded systems , as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, it is also known as an extension language. Scripting languages are also sometimes referred to as very high-level programming languages , as they operate at a high level of abstraction, or as control languages , particularly for job control languages on mainframes. The term "scripting language" is also used loosely to refer to dynamic high-level general-purpose interpreted languages , such as Perl , [2] PowerShell , Python , and Tcl , [3] with the term "script" often used for small programs up to a few thousand lines of code in such languages, or in domain-specific languages such as the text-processing languages sed and AWK.
