Hello, everyone, and this demo, I'm going to show you how to use the system, see, tell comment.
System Seitel controls the System D system and service manager.
We use System C tail command in order to interact and manage System D surfaces on units.
System D is considered the heart of the Linux operating system.
If I would like to list all the system units and surfaces, I can run the command system seitel then
list.
Then dash units.
Then space dash dash type space service.
It enter, as we can see here, list of all the system units and surfaces on the system.
Now, if I would like to check the status of a surface, for example, I'm going to use the the H GTP
deep surface in order to check the status of that of that sir surface to enter, as we can see right
now.
The status, it's active.
If I would like to check the status of another surface, for example, network.
Network manager, etranger, it's also active.
And there is also, if I would like to check the status of the S.
S h.
D.
That surface, same thing.
Exactly.
Now, if I would like to stop.
Surface.
I can use the same thing System told Tilden, rather, them to use the statis.
I'm going to type stop then the name, for example.
Let's try and network here.
Network manager.
Enter.
Now I'm going to check the status of the network manager, who, as we can see here, it's inactive.
If I would like to start the surface again.
System C tailed and start network.
It's network manager doing a hit enter.
Dan, I'm going to try this system C two status, the network, as you can see here, it's active again.
Sometimes if you would like to disable a certain surface and we did like we don't like that surface
to be enabled anymore.
So I'm going to use the class system C tell them to disable.
Then after that, for example, network manager.
I hit Enter Now the surface.
It's the SERPELL.
Now, if I would like to enable it again, I can use the comment enable.
And sometimes you use the option Dash Nationale, which means that I would like this surface to be enable
Ratner and I hit enter.
You can see here know going to check the status of that surface network.
Network manager hit Enter and it's active.
So.
If you'd would like to check a status, we tied the systems details sighted in the name of the service,
there are many services that we have and the Linux operating system, if you'd like to start to surface.
We used the start command.
And if we would like to stop, we use the stop command.
And sometimes if we would like to restart the surface again and we have some issues with the surface.
For example, the network manager, I can use the command to restart Inter.
Now, if I would like to check the status of the network, many your service, as you can see here,
is active.
If I would like to disable the service, I'm going to type the command system seat held in the sample.
Then the name of the service.
If I would like to enable any surface in the system, I can use the command system detailed then enable.
Oh, if I would like to add dash dash now.
Which means that I would like to enable the surface right now.
Thus, conclude our session.
Thank you.
And see you.
And next lesson.
