What Is a Script?

A script, also referred to as a computer script, is a set of commands that are executed by a specific program or scripting language. Scripts can be utilized to automate processes on a local computer or generate web pages online.

A script essentially consists of a program or a series of instructions that are interpreted and executed by another program, rather than directly by the computer processor. Some languages are specifically designed for scripting purposes.

The most popular scripting languages include JavaScript, Perl, and REXX. Compared to more structured and compiled languages like C and C++, script languages are generally easier and faster to code. However, scripts may take longer to run because each instruction is processed by another program first, requiring additional instructions.

In certain instances, a script refers to a list of operating system commands stored in a file, which can be executed sequentially by the operating system’s command interpreter when the list name is entered as a command.

A script can also be defined as a sequence of instructions used to determine the presentation of a sequence of files.

Scripts are available in various languages as they are open-source, allowing users to view and modify them as necessary. They do not require compilation but can be compiled if needed. Scripts are easy to learn, write, and port between different operating systems. Additionally, scripts are faster to develop compared to full-fledged programs, and some individuals and companies use scripts as prototypes for actual programs.
