All right.
I'm going to tell you about this new feature in RHEL 10,
which is completely useless on the RHCSA exam.
And that is RHEL Lightspeed.
So what is going on?
Well, RHEL Lightspeed is AI that is integrated in RHEL 10.
And in order to do it, you need to meet
a couple of requirements.
Requirement number one is where your system
is registered with Red Hat.
That is why Lightspeed is useless on the RHCSA exam,
because on RHCSA, you're on a disconnected system.
But at the same time, Lightspeed is so useful
that I need to demonstrate it anyway.
I will show you in lesson 12, which
includes software management and subscription manager,
how you can register your system with Red Hat.
For convenient demo, I already registered this system
with Red Hat using a subscription manager register.
And as a result, I can install software package.
So sudo dnf install command line assistant.
So obviously, you need to enter the password
for sudo privileges.
So there we can see that it has found the command line
assistant.
And yes, I want to install that.
And just answer yes on these prompts.
These prompts are appearing because this
is the first time we are getting in contact with the repository
for installing software.
And this is the GPG key that verifies the integrity
of the repository.
And yes, this is OK.
Otherwise, you can't install it.
So now I'm installing this command line assistant.
And we can give it a try once it's done.
In order to try, you are using C. C
is a command that allows you to use the command line assistant.
And in this C, I'm using a question
like, which command do I need to find all files, all hidden
files on my system?
Make sure your entire question is between double quotes.
Then it's asking rel light speed.
Now, the essence of this rel light speed
is that it is contacting Red Hat servers.
And for that reason, it only works on a registered system.
And as I told you before, registered systems
require internet access.
You don't have internet access on the exam.
So no matter how beautiful this is, and look here,
we have the example output and some explanation as well.
It's useless on the exam.
Nevertheless, another one, C, write a script
that works with one argument that indicates
a number of minutes and counts down
until it reaches second zero or something like that.
I want to show you that this command line assistant is
really capable of doing interesting and very powerful
things, like right here.
Look at that.
It's a complete batch shell script.
And no matter how convenient this is,
you don't have it on the exam.
Does that make sense?
Well, it absolutely does.
Because if you are working on Red Hat systems,
in many cases, these Red Hat systems are disconnected.
And that means that you still need to master the skills.
And that is what RHCSA is all about.
