Evolution and Historical Significance of Shebang
The shebang has a cool history. It started way back in an old operating system called Multics, but it really took off with Unix. There, it became the go-to way for computers to figure out which program to use for different scripts. Now, it’s not just for shell scripts anymore! The shebang works for all sorts of scripting languages, making it a cornerstone of how Linux and its friends run these handy tools

Using Shebang in Linux
Imagine you’re working on a Linux computer and have a recipe with instructions written in different languages. But your computer only understands English! That’s where the shebang comes in. It’s like a tiny label at the beginning of the recipe that tells your computer which “translator” to use for each language. This magic symbol, #!
, followed by the interpreter’s path, is the key to understanding and running all sorts of scripts on your system.
