Hello, everyone, in this demo.
I'm going to talk about the processes, comments and Linux operating systems when we are on programs.
We can define these programs as processes.
Basically, we can say when we work on Linux operating systems, we can look and find that current processes
that are running.
We can run, for example, pierce command of top command in order to find processes that are currently
running.
If I would like to show a report, a snapshot of the current processes I under P.S. comment, as we
can see here, the result or outcome of the peace command, we have the P i.
D.
Is the process I.D. t why is the name of the controlling terminal for the process.
Time is the c.p.u time of the process, show it in minutes and seconds.
And to see M.D..
Is the name of the command that was used to start the process.
If I would like to run the PSC command with options, for example, I would like to was the option.
And in order to display the processes of all users and also option you in order to provide detailed
information about the processes.
And also, I would like to use the option X in order to list the processes without a controlling terminal.
Then I hit enter.
As you can see here, these are all the processes that are currently running.
Go at the top here.
This is the command post in a U x.
We have the column you user is.
Is the user who runs the process.
And we have the Persis idea here.
We have the percentage C.P.U is the C.P.U utilization of the process.
And then we have the percentage.
Memory is the percentage of the physical memory on the machine.
We have the V.
S Z visual memory size of the process.
In Kilobyte.
Then we have the R.
S.
S the size of the physical memory that the process is using.
Then we have where are the Experion about the T t why is the name of conjoining German for the process.
And we have the start to the process.
Is that good.
So the start code here we have for example, the Z for Zombi.
It means the process is not working or ESCs says sleeping or the the code.
Ah.
Which is running.
So we have you sleeping.
And if we have the R which is running or is it zombi.
This for example.
And do we have the Sakti of the time when the command started it, the time and the command that we
are running now does move on to the next command.
If I would like to run the Piesse with option Desh E in order to display the all the processes, then
I would like to use the F option in order to file detailed information about the processes.
And I hit enter.
See here, it's different outcome than the previous comment that we have used, the peace and the option,
a new X, and we can see here all the processes that are currently running when the system.
You can't go here to the top.
We have the user here.
Is this guy similar to the user that we had in the previous command?
The user, Colin.
So this is the user who runs the process and puts this idea here.
And we have a new call in here.
BP, the BP I.D. is the idea of the parent process.
And we have to see same as the percentage C.P.U, the process, C.P.U authorization.
And we have this time here, same as the start, the time when the comments started.
And terrorists we know and already have explained those comments.
Let's move on now, if I would like to use the pipe.
P.
S dash.
Yes.
So I'm going to run the piesse then option dash e f then pipe less.
So why did Dad?
Because I would like to show just only one dish.
As we can see here, we only have one page.
If there is also another command, if I would like to use the P.
S dash e f, then I use the pipe, then Grib I'm going to grab the user's stood in so I can watch what
I can use the pipe with the grip command in order to show the processes that are belong to a specific
user.
So as we can see here.
So what.
When I, when I run this command I use the grip student in order to shore all the positions that belong
to you as a student.
I can do the same thing.
P.S. Dasch e f then tight grip Brutsch.
So I'm going to show all the position that I belong to.
Road user, if I would like to also use discriminate Pierce Dash uppercase U then student.
It would be the same thing is going to show me.
It's gonna be different outcome, but it's gonna be the same thing is going to show me all the processes
that are belongs to user stood.
Now, if I would like to.
Display Linux processes.
There is another command also.
We we what they have demonstrate the P is command.
Now I can use also another command, the top command, in order to display the processes on the system.
So the good thing about the top command that that provides a dynamic Real-Time view of running.
Overrunning system.
It.
It also shows the system summary information, as well as a list of processes or Thirith currently being
managed by.
The Lennix could.
If we would like to get more information about this to command, we kind of go to the Manbij.
P.S. you can find more information on the option that we can use.
As you can see over here.
So here to see every boss, this is on the system using standard.
Syntax, you see here, all the examples that can we can use with the Pierce comment and go back to
the main screen, then if he would like also to find information about the top command, a type man,
then the command top, as you can see here, you can find more details, information about disconnect.
That's concludes our session.
Thank you.
And see you in the next lesson.
