What is the Bash Shebang and How to Use it

May 13, 2024 by Jeff Wilson

This tutorial will explain what Bash Shebang is and how to use the Shebang characters in Bash scripts on the Linux system.

Shebang is a sequence of two characters: a number sign (#) and an exclamation mark (!) that gives us the #! at the beginning of every script we need to write. Shebang is also known as hashbang, pound-bang, or hash-pling. It is always defined in the first line of the script and is ignored by the interpreter.

In the next paragraphs, we will show you how to use the Shebang with real examples. Let’s get started!

Bash Script Examples

In this tutorial, we will explain the most common bash operations while also showing you a few bash script examples.

A Unix shell program interprets instructions and programs in the form of commands. These commands are either directly entered by the user, or they can be run in sequence from a file (called a shell script). An important distinction of bash scripts when compared to other coding languages is that they are interpreted and not compiled. When you write a shell script and then run it, it’s interpreted by your operating system, with no compilation required.

Bash scripts are a versatile and handy tool that most system administrators love using to simplify their workflow and automate repetitive tasks. With scripts, you can do almost anything that you can do using a normal shell environment.
