Shebang: meaning, definitions and examples
๐ง
shebang
[ สษหbรฆล ]
computer programming
A shebang is a character sequence consisting of the characters '#' and '!', followed by the path to the interpreter that should be used to run the script. It is typically found at the very beginning of a script file. The shebang indicates to the system which interpreter to use when executing the script. This is important for ensuring that scripts are run correctly in different environments.
Examples of usage
- #!/bin/bash is a common shebang for Bash scripts.
- #!/usr/bin/env python ensures that the script runs with the Python interpreter available in the user's environment.
- #! /usr/bin/perl is an example of a shebang used in Perl scripts.

Etymology
The term 'shebang' originated from the combination of the characters '#' and '!', which look like a symbol (hash) followed by an exclamation mark. The word 'shebang' itself is a colloquial term that started gaining popularity in Unix programming communities in the 1980s. The first recorded usage of the word appears to have been in the context of Unix shell scripts, where it was used to differentiate scripts from regular text files. This character sequence effectively communicates to the operating system that the file is not merely a text document but rather a script that requires a specific interpreter to execute. The shebang's design is a practical solution to the issue of running scripts in a portable and consistent manner across different Unix-like operating systems. Over time, the shebang has become essential for the development and execution of scripts in various programming languages, helping ensure the right interpreter is invoked, thereby enhancing script portability and usability.
