Basic Perl “Hello World” Script (hello.pl)#

Let’s start with the basics. Here is a straightforward “Hello World” script written in Perl. Create a new file and name it hello.pl.

#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;

print "-----------\n",
      "Hello World\n",
      "-----------\n";

In this script, we’re using Perl’s built-in modules for error handling (use strict; use warnings; use diagnostics;) to make sure the code is robust.

Introducing Expect Bindings with Perl (test.pl)#

Now, let’s dive into the main topic: how to use Expect bindings in a Perl script. Create another file, test.pl, and add the following code:

Mastering the art of Continuous Delivery is about more than just pushing code onto a server. It’s a delicate balance of managing your technology and the people who interact with it. One major stumbling block? The tiny differences between machines that happen when someone decides to make ad-hoc changes. These may seem trivial, but they can cause massive headaches when it comes to debugging and troubleshooting.

The endgame here is clear: Create a system so streamlined that there’s no need for anyone to manually log in to make changes. Achieving this means fewer bugs, faster deployments, and ultimately, a happier team.
