Linux Tutorial Series – 180 – Shebang

Here is the video version, if you prefer it:

The first part of a shell script is called a shebang. A shebang tells the kernel what interpreter to use to execute the script that follows. (Shotts, 2019) By interpreter, I mean the shell. (“Does the shebang determine the shell which runs the script?,” n.d.)⁠ You will recognize the shebang because it is the line that starts with #!.

A sidenote: shell scripts are interpreted, not compiled.⁠

Let’s now write a shebang in our script. Let’s name our script In it, write the following as the first line:


That tells the kernel to interpret our script using the bash interpreter. You have different-looking shebangs for different interpreters.

Hope you learned something useful!
