So, guys, welcome back.
In this year, we are going to see the next best comments.
So I have written already the comments, what I want to discuss in this topic and not that text text
editor, not to miss any comment.
So first, open your permanent address, click on this menu button or button and hear type to search.
So you get this terminal and you will get some small size so that they can edit and go to preferences.
Now we are going to do some smart customizations for our terminal.
And there you can see these are the settings and these are the shortcuts.
No, I'm going to add some shortcuts.
These are our user preference.
You can edit shortcuts for your taste.
So I'm going to send you to control controversy and controversy and basters controversy and to increase
the font size for this.
But what you're going to do is click on this custom font.
Actually, it will be this will be your default envelope.
And if you want to increase the click on this custom phone and click on this front type and you need
to increase the font size to 18, it will be good to easily view the content and on cross.
So this is our time and here we need to input some comments, I mean, we should go to submit some comments
to the Turner and it will go down.
So let's check.
What is this one?
This one is there is a note which we have created, Nikki, and this one is the one to mention, I mean,
the machine's name.
So I have logged in as Nikki user in that machine.
We want to address the stuff that this user has been logged into this machine and there is this terrorism.
But we'll talk about it in a few moments.
And this is the data that indicates the.
Sure.
And there you can see for it and there will be a concert blinking.
And this Castle Brinkman's that this has been this shell has been waiting for comments to enter.
So the command will be learning use in in what they truly are in Illinois about what Carandiru triggering
will be, which transfer print working.
Not if I don't get the part in which folder I am running this through.
Right.
So it's in slash home slash Nikki.
So starting from rooters, it's in the home territory in that Nikki folder.
So let's for further click on our file manager and this fund manager before we open our home folder.
And you can see right click on this and open and you'll get the same, but.
And if I take PWP and I get the same output from Niki because the Tekmira starts from the home territory
of that user.
So in normal graphical user interface, you never get to the first right for you in order to navigate
to that, there are four that you need to know what the rules are present in your current territory.
Right, to view the contents of the folder under the paperless.
So you can see the output and in my home, Nicky, the tree trimming the folders, so in my home directory
there, the step further and further music for the public and you can see this for color is a little
bit bluish color, right?
I go to my first and then you can see these are folders and the they are indicated by the blue color.
And not all of those are indicated by white color.
So in order to go into the desktop, we need to take Siri, Siri stands for change and we need to give
the floor.
You need to mourn.
So if you say Siri, Desktop and Houtan that, you will move to desktop.
Now, if I.
I get home, Nikkie and then remote desktop.
That's what it's showing us.
Desktop.
And now we are going to create a fight to create a fight, we need to touch the let's say.
Temporarily.
So I have created a temp file and now to use the contents of this discovery.
I want to this.
So I have already created the system to protect me.
OK, let me keep it.
No, I have created this protective boom.
There are some extra arguments you can do to deserve to get more information like this minus.
So at this point, this year produces an output, and that is and that gives some more information,
that is not in order.
OK, we'll talk about in this simmering topic.
So if I want to remove the file from the directory, I want to say Aurum and the filename.
So if I paperless, we can see that our file has been deleted successfully.
Remember, this is a really simple process.
You cannot you cannot restore the digital file in the reenacts.
So if you delete normally from the file manager, it will go to recycle bin.
Then you're going to be later restored.
But from a terminal you cannot return for.
So let's I want to create a new folder to do that, I want to take the of comment in the stands for
Makeda and let's test.
Professor Ellis, you can see there is a template text for which you have created before and then test
for the.
So if I want to move back more into the test, I want to test, right?
If I say Alice, just not because there are no false since we have created this test territory just
recently.
So I know I how came back to my test territory.
Well, what if I want to go back to the desktop?
So what I can do is create.
Nikki and desktop, right, so this is very long path and if there are so many for back then for us,
if you need to go well, it's very time consuming and tedious task.
So what I want to do is I want to address minister.
Supremest said this and order no, the DOT represents this current retreat we are in and dot dot represents
the parent, the tree of this territory, so the parent, the tree of this desktop.
So I can easily navigate to the parent using KDDI and order I you can see I have more to the parent,
which is desktop.
So in this way you can use these shortcuts to navigate the parental tree easily.
Now let's also see what is dot and the dot.
And I be the same word because DOT represents the current directory from the territory onwards.
And you can just imagine the.
But this but as this dark chocolate.
And the next one I'm going to tell is out of the Army Air Command, so autumn, dear, that autumn stands
for remote territory.
Since we have to retreat in our desktop folder, then I can just sit at the artist.
And the less so there is no teschner because we have the leader using Ihram, they are going, yeah,
that's fine.
OK, let me make that point again now.
I can see a list from the.
I can view the contents of Techdirt using a less space.
So there are no contents in that right.
OK, now let's go to Taschner and now let's create a new file.
Certain to be.
First, let's not forget there is a time to that, so now I'm going back and now I want to dilettantish
territory, so we have to learn the comments that are coming out of the airspace that I represent.
You want to be great.
So if from the artist, so it gives us some arm the failure to remote territory.
Not so this your commander is today.
Trioli When it is empty, it can order it when the territory contingency plans are for us.
So to overcome this, what we want to do is you want to go into the territory and do it already or even
you can just force retreat using armed gunmen.
So Arab miners out of this hour stands for rigourously.
That means if the test can fail to convince any foreigners and in order for us there are any foreigners
like some supporters, then this comment will automatically delete everything in this dish folder that's
that's called reclusiveness.
And it means forcibly, forcibly.
So we are using this switch.
I mean, this option in this letter, because this directory is not empty.
So that's it.
Now, if I say less so, that is not.
Well, we have successfully deleted the folder, even though that folder is not a bit.
This is very dangerous unless you cannot educate with the user permissions.
OK, we'll talk about that later.
Now, what I want to do is I just created for OK, since we have created the file Democratic Party to
view the contents of the file you need to get, that is a comment which displays the contents of the
file.
And if it's a cat protected, it shows me nothing because there is no content in that text file.
So one way to write this, I set a goal, there is a common goal, and if I hit enter, it will send
the output output as the as the string we pass as an argument to this comment.
So if I say I call it princi, if I say I call Nikil.
So.
So it prints high, it prints Nicole, so whatever we pass in the street, it will be printed as an
output.
So now we can read at this hour to hour to Stiffle.
So we are learning a new thing here, and so we are just printing out this nickel and then we are storing
it in Canberra.
This is called redirection operator.
It means that the output of this first comment will be stored in a file.
So if I hid under, there will be no but if I the temporality, our nickel will be there.
So if I get them to.
So the nikil is not completely.
Now, I want to show you another one that Cernik Hollowell.
Well, if I said the word greater than this also kind of redirection operator, but what it does is
it deletes are the contents of the Democratic Party and it is only discontent.
Ed, so it appends the contents of this comment to this text, what if I stand up and say so if you
help, I put the 10 comments, you can travel through those 10 comments using the Aparo in your keyboard.
So if I say Aperol, I will get to know if I knew the contents.
Democratic Hollywood has been open to the end of the fight so far.
What we've done is we have printed all of the handover and we have appended to the term protective order.
And what we have done is next.
The cat comment shows us the contents are democratic state and it shows us that Nicole and Haulover
OK, no, I told you that Aparo travels through the previous comments you have typed right now.
If I press Aperol once, it will give me the this comment, because this is the comment I have previously
typed.
Now, if I up again.
You know, it really shows a disconnect.
So if I type A again and then it shows a disconnect, now I want to again redirect this or put into
templating 65.
OK, now what this does is it will it this discover and I'll put piece or return the contents of the
protective, that means the previously store contents of the temporal textile will be deleted and this
output will only be stored in the text file.
But I care and.
Now the only output is nickel and orit's has been stored in the previous.
We have two lines and those two lines for deleted and output of the only disconnect will be stored in
the democratic.
Now, what we can do is we can.
By this output, to the less, more operators and experts know what I want to raise, I can pipe this
output to the latter model.
What is what this does is this pipe operator takes the output of this comment and it will give the input
to this comment.
So if I hit enter, OK, this more just shows us the contents of the text file.
Now there is similar command to the more that is less.
So the cat text file shows us this output and that will be given as input to this rescaling.
That is command is very helpful.
When there are so many hundreds of lines of content in your text file or any file, then you can just
start from the beginning and you can just scroll like this.
So there is only one.
If I scroll down, I get this Arason.
So could this last comment I can say just to.
So that his comment will be not important, but in the future, we will see the comments importance.
OK, now we are going to copy the files from one letter to the end of the right unless we have the template.
Now, let's make a new directory called Hash again.
Officer Ellis, I have the exact file and afford not to copy that etched into the tree are you need
to see CCP, which stands for copy and take the template and then the destination you want to to test.
So now, if I say a less test, that means I'm really not convinced of the test further, I have this
term actually in my test for we have successfully copied or file into this Florida.
All right.
Now, let's, uh.
Now, let's go into the territory and promote that fight.
Want to arm them?
So I'm going to going back to my parent, my daughter, if I say unless I have that under Florida now,
if I say there is empty, empty.
So now what I want to do is I want to more distant to the test of Florida.
I want to do is Yumba stands for both.
And I want to take the temperature and then to the destination.
I want to move to test now if I hit enter a list.
So there is no temperature in Florida because it has been more to test Florida.
Let's see that one versus test and less and less our temperature has been successfully moved to the
test.
Florida, and this is one way of moving the Florida and this more common can also be used as the renaming
file because we are moving this file to the end of the file.
Then automatically the contents will be preserved and this text file will be deleted.
So this comment can be used to bring him a file.
So I want to them to be so efficient.
Alas, there is no temporada because we have moved to the temp, to the text.
So there is no particular current in the Linux we just use and we combine to rename a file.
And sometimes you need to know about what you have been logged in.
Sometimes you can see here I am logged in as Nikki, but there will be some situations where you logging
into the Secich or you can just you just get basic shell from the victim mission or the vulnerable mission
you are trying, then you need to know the username further.
There is a commander who am so on typing.
Who am I now put gives us the username you have been logged into.
So I'm going to go back to my partner and never say unless there is to Florida.
So one way to find the files is you need to sometimes search through the computer for some particular
file.
So one command is looking at command.
So I want to say look at space and the filename I want to search in my computer.
Since we know that and protecting what is in there, let's locate further file temporarily.
It will give us the nothing output because.
So but you think that this look at command has been failed?
No.
This look at command will use the database of files.
And if we create a new really new file that we need to update that database.
To do that, you need to type pseudo update DB.
So this sounds somewhat confusing or like complex topic, we are just using the pseudo that means route
user permissions and we are updating the database, so I'm going to type in my password now.
It will automatically update the database and cash for our files.
And if I and.
And so, you know, if I look at the time to that, you know, I get the results home, Nicky desktop
and that quarter I got the I had the computer text file.
So we need to upgrade every time we have created a new file.
So we have got this look at computer output and we can.
Just look at the file is in the rocket command right now, there is another command command command
to read the manual pages for any comment.
For some analysts now it is reached directly contents.
And you can see there are options we can do that you can do to the Atlas command to get some more information
about the fighters and territories.
And you can check the manual police if you don't want any comment.
And the next comment we want to see which command these, which command you use to test whether the
software has been installed or not.
And it just opened the directory where the software has been installed.
That's it.
But which Python three or so years have been?
Python three.
So my Python three binary has been in the U.S. or been Python three.
So this is one way you can find if there is a programming language, start or not on the remote mission.
So this is very important.
When you want to get a special orany preregistration, you can just check if there is a particular programming
language is start or not.
Right now there is another current karate's.
And if I say what is a this it just this basic idea of what the commanders if I say what is the address?
And it just brings out the first line of the manual, that is the directory contents and there is another
command areas.
So what if I say a real is equals to a plus minus.
So and this minister shows us the person for us, including the hidden territories.
So he these other territories are the fault of those that start with that.
So if it's a new file name that Nikil, then if I go paperless, then that file will not be displayed
in the square.
I want to use the new paperless minus here to display are the person folders, including The Hidden.
Now we can put the addresses for some specific comments.
So I think if so, I am ready to take plus minus here every time.
So instead of that, I can just add years that command to this variable temp.
And if I return to know that Urías name has been included and if I say just temp, this command will
be executed.
So let me show the same output.
So if I say a temp and if facilities money, the bottle puts out the same because I am just fine keeping
the nickname for this comment or just putting a last name for this whole comment.
Ascham.
So I think I have covered all the comments, guys, in this file.
Go, go.
OK, I have not called history so history.
Is is come and tell us the history of your comments you have given to the.
If I type and you can see these are the comments you have given to the right, you can see there are
a lot of comments.
So one way to build this, there is a way to do this history contents, if you want to say history,
space minus the.
All right, I'm wrong.
OK, let's see the arguments, sorry, minus.
I'm so sorry.
This is not know I pushed Tapestry so you can see if I take the upper arrow mark, the there is some
arrows on because there are no history comments.
It means that all the comments in our history are deleted.
So I want to manually enter every comment.
So if I say history, so there is only one comment that is we have a different history.
So in this way we can take the history C to clear of the history so that this is all about the next
comments.
