Scripts

A script is a sequence of instructions that directs a computer program or an actor's performance. In computing, scripts are typically plaintext files executed by an interpreter at run time rather than compiled into standalone executables. In theater and film, a script is the written text outlining dialogue, action, and stage directions.

In computing, scripting languages such as JavaScript, Python, Ruby, Perl, Bash, and PowerShell are used to automate tasks, glue software components, and control applications. Scripts are usually shorter and easier to modify than traditional applications, and they often run within a host environment or browser. File extensions include .js, .py, .rb, .sh, .ps1, among others.

Scripts emphasize rapid development, readability, and portability. They can be platform-specific or cross-platform, depending on the runtime. Interpreters and engines determine execution, rather than compilation. Security considerations include code injection, permissions, and the need for safe execution policies and sandboxing in sensitive environments. Scripting is a common tool in automation, data processing, and DevOps.

In the performing arts, a script organizes a production’s narrative and instructions for actors, directors, and crew. Formats vary by medium; plays, screenplays, and teleplays each follow distinct conventions for dialogue and stage directions. Scripts evolve during rehearsal and production, with revisions reflecting artistic decisions and logistical constraints.
