Hi there.
Welcome back.
Welcome to the final lesson of this section in this list and we're going to learn the more important
commands.
Command is the process.
OK.
The commands are number one and number two is no hope.
OK.
With the help of commands you can do some more airballs stuff as compared to the previous tools.
OK.
So let's see how I could do this.
OK first talk about your future utility your future utility is a powerful tool in Linux.
This utility gives you the information about the file user or the process being currently used by a
file or directory.
OK.
So how do you use this tool.
OK suppose I want to see information about who directory then you need to type if user OK and forward
slash OK for forwards less represent the rubric.
You can see this kind of information here.
It's currently showing us the process id and so access type.
OK.
And if you want to see this information in detail you can provide the search like I've the.
And hit enter key and now you can see clearly here it shows us the user the process ID and it exists
existed.
Come on.
OK.
So here user will get the first user is rogue.
Is process ID.
It's showing here Colonel exegeses mom can come on this route.
The next one is push on process I.D. one of us who've been accessed by P R C and Common's is Tim D.
OK.
So in this very you can get the information about the Directory the root directory is currently being
used by the user Prashant and route.
OK.
So these are the processes that are currently using the root directory.
So what are these axes eggs.
OK so let's see.
So there are different kinds of access type.
OK.
Suppose you get in the output.
See that means it is current directory.
Then if you get it that means it is being run.
If you get that means open find if fees all Miguel in default display mode.
If you get capital left that means you can file for writing and Capital-FM is also omitted in default
display mode.
If you get small that means it is the rope access type group.
And if you get small that means it is managed in a file or shared library.
Here you can see it shows us the pressure is having the access type RNC.
That means you can get a directory and the next process shows us only our That is a group.
So in this way you can get the information in detail with the help of this come on.
OK.
Like c'mon we can also send the kill signal.
We'll get to these processes.
Suppose you want to kill all the processes here then you can simply said I often get a signal and hit
enter.
And now here you can see the entire system restarted.
So let's log in again clear.
And let's run again if he's there.
V.
OK.
Now we kill these processes by sending the signal key.
But suppose there are lots of processes and you want to kill a particular process.
So in such cases you can soon switch like a hyphen.
I use an interactive mode.
OK in which it will ask you whether you want to kill the process or not.
And in this way you can kill a particular process without affecting other processes.
OK.
So just Plourde eye for an eye and he Danka.
OK now here he is asking me if I want to kill one 5 9 4 process.
No.
Asked me for explosives to kill me and I won't press.
Yes.
OK.
And after pressing Yes the there is no file present in our Krongard the slow create a file student last
year.
Now here the file is present and future.
You can get the details of the file system.
OK.
All the processes which are connected to the file system weren't responsible for the file system.
Then you can get the information about good like this overlord in the file as in code.
OK.
And you can also get it in detail by Guarani slash.
OK.
In this way you can see all these processes are related to the file system on which in this file is
present.
In this way you can use the user utility to get information about a particular file user or direct to
user OK or the process which is using the directly or connected to the directory.
OK the next one.
And which is the important command.
OK.
He's no hope no hope is a utility which is used to run a program at the background.
Even if you are Lagat from the system.
OK.
So let's see how it works.
So I want to bring my host that is called off line.
So who said this had the background you just need to type.
No how then big enough to call off line and send it back around again cannot here can't see it displays
the message are ignoring important happening or you know how got that means there's no hope.
God Oxley's glittered in the current directory.
So despite your love of OK now we are logged out type username and password.
OK we are back.
And then here you can see no hope thought out file is created and you can see its contents.
My Gad you know how it got out OK.
And it is the output of the bin.
Come on and you can check it the command is running or not.
With a stop key and type S-3.
So still.
Come on Bing.
And here you can see it is all.
Come on it is running in the background here and you can kill this command by sending the signal 9 and
select your signal line.
Look cool ok and the process stop press and get this stuff clear.
You'll get in this way you can use the fuser and no hope.
Come on.
OK these are the most powerful tools.
So in this way this process management section is very useful for you to manage the processes and make
sure you run your system faster.
OK.
