How do you use shebangs and portability with a short example?

In Perl, a shebang (#!) is used at the top of the script to indicate the path of the interpreter that should execute the script. This is important for portability because it allows the script to be run on different systems without needing to explicitly invoke the interpreter from the command line.

Below is a simple example of a Perl script using a shebang:

#!/usr/bin/perl use strict; use warnings; print "Hello, World!\n";
