I have just explained to you that we could work with different shells using graphical user interface
applications, gold terminals.
And this my computer I am using I term to application.
And in those different tabs, I am connected to do different schell's of links computer.
Here was Basho.
And here with CHL.
And now in this lecture, let me show you how you're able to get information about specific shell that
is currently being used.
And next hour, I'll show you some additional comments that will give you some information about Lenos
computer that you are currently in.
So if you're anti-government, aircon, dollar sign, shell and press enter.
You'll get following response.
In my case, I'm running now.
Buy a shell.
I am connected now to bash shell process inside of the wounded Lenos computer.
And what is being.
I'll explain you a bit later.
Let me answer the same command in another step where I have started.
See each shell echo dollar a sign shell.
I got for some reason.
Empty output.
Let me try alternative comment, echo dollar sign.
Zero.
And now I get response.
C, h.
And that means that now I'm running.
C, h.
Shell in this terminal window.
And please note is that there is already a difference between interpretation of the same comment.
Ecuador sign shell here in this C.H. Shell.
And here in this Bestival here, we even don't get the result or result wasn't correctly recognized.
All right, let's brosset.
And no, let me enter some additional commands that you are able to use in order to get information
about specific Limas computer.
You are currently in the command.
Is your name.
And if I will simply type your name, I get the answer links.
There are additional options you are able to use with this comment.
For example, you name Dash eight.
With this comment, you're able to get additional information about Linux computer like Hostname and
Brossel.
Also, you're able to use Özer option.
This ah was this option.
You'll get information about Linux Kandel.
It is a version for nineteen seventy six Linux.
Keep in your case you could get an also version of course on another computer.
Let me quickly switch to a winter computer.
It is basically your little machine that is running on my macros computer.
And let me open up terminal here.
And first let me use echo comment echo Dola a sign shell in order to verify which Shell is being used
right now.
And here I see the same result as here instead of the container.
It means that here I am also connected to Bash Shell.
And next, let me enter your name.
There's a I see that I'm using Linux Lubutu here with my Russian and you could get the kernel version
using separate option.
You name this.
Ah.
And actually you get the same result as is included here in this.
And of course version of this kernel differs from version of the kernel here inside of this Linux container.
All right.
That's how you're able to get the version about specific software installed on specific Linux computer.
Next, let me enter, for example, uptime.
Come on.
And here this output, you'll see current time and total uptime of this.
Also, you'll see quantity of columns locked in users.
But we are actually locked in as a router user.
And this router connection is not counted as user connection.
That's why here I see zero users.
And also you see here what average of this server at the moment there was a lot.
And that's why here you see all zeros.
Great.
Let me also enter additional options here with uptime command.
And this option is Desh Pete Freedom.
And it will preprint this result.
And I see that uptime of the Celera is a 21 hours.
Forty one minutes.
Great.
But you may ask me a question why this time is so huge.
We have just started this container.
That means that before this container was actually stored as a snapshot in the image and before this
container was running on some ares our computer.
This way here you see such large uptime.
Let me switch to another computer here and type the same command uptime DSP.
I get that uptime of this Yodle machine is twelve hours.
Great.
That is next command.
You're able to use next one.
Let me quickly clear terminal.
And for that you could use a combination.
Come on team or control it on windows or type.
Clear command.
And it will clear output like this.
Let's enter our command w this command shows which users are currently locked in to Linux.
Sarah, let me enter a same command here.
W and I see that user with user name Mogadon is currently locked in to this computer.
All right.
This is how you're able to get basic information about the computer.
You are currently in.
Next.
Let me explain why we are actually able to enter such commands as Alas, c.D, and so on, and how Shell
actually understands that specific sequence of characters is actually out.
Let me explain that in the next lecture.
I'll see you now.
Bye bye.
