What should I use for a Perl script's shebang line?

Question

Which of these is better or faster to use as the shebang line for a Perl script?

#! perl

#! perl.exe

#! fullpath/perl(/perl.exe)

#! partialpath/perl(/perl         


        

Answer 1

The first line stands for shebang. It basically tells the program where Perl interpreter is located since Perl is interpreted language. On Linux you can type in terminal:

whereis perl

which will give you exact location of it. Usually it's inside /usr/bin/perl. This means that you want to make shebang regarding to /usr/bin/perl

#! /usr/bin/perl

use strict;
use warnings;
use v5.10.1;
.
.
.

This is just some good practice, hence it's obviously fastest solution.

I hope you find this useful,
