How to write a very simple script in perl?

As always starting off with a Hello World script. Create file in your home directory with the following code and make it executable by running:

$ chmod +x myperl1

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

Run the script

$ ./myperl1 
Hello, World!

Newer versions of perl v5.10+ have another way of printing out output, but you have to specify the version in the script to use.

#!/usr/bin/perl
use v5.22;
say "Hello, Universe";

$ ./myperl1 
Hello, Universe
