Shebang is slang often used in the computer Perl programming and other script files. The term shebang refers to the “#!” located at the top of many script files that point to the associated program’s path. For example, in a Perl script, the complete line may look like the following:

#!/usr/local/bin/perl

This line instructs the operating system running the Perl script on where the executable for Perl and its associated files are located. This line is commonly only required in Linux and Unix variants, users running Perl in Microsoft Windows do not need this line.
