Shebang

Noun · Development

Definitions

  1. The #! character sequence at the beginning of a script file that tells the operating system which interpreter to use to execute it (e.g., #!/bin/bash, #!/usr/bin/env python3). The name comes from combining 'hash' (#) and 'bang' (!).

    In plain English: The special first line of a script file that tells the computer which program should run it.

    Example: "Add #!/usr/bin/env node at the top of your CLI script so it runs with Node.js when executed directly."
