Hello, everyone.
In this listen, I'm going to talk about the hierarchy structure and the Ditrich T.G. and the Linux
operating system.
In any operating system, we have Derek Cheese and Five Systems.
For example, when we had a store, windows are working system, all directors under five systems are
installed under siege like.
Same thing for the Mac operating system.
All directors and five systems are installed on Macintosh hard drive.
However, we can't create directives and five system either on Windows or Mac operating system.
Most Linux distributions have similar directories and five systems.
All those strictures on file systems are installed under the forward slash, as we can see here in the
Seagram.
This is the forward slash and we call this a rule directory or orge fi system.
We consider the root directory or the Route five system the top level or the parent of all the directories
under five systems, a Linux.
We can imagine this hierarchy structure as a family tree and Linux, as we can see.
And Mr. Graham, the top level.
Or the parent of all the directors and the five system, Lennix is the four Senesh, then whatever comes
under the forward slash.
We consider them children.
These children also have our parents.
For other directors and fire system under Tim.
See, for example, we have this slash.
Let's start first with the slash, the forward slash disorder, forward slash.
As we said, it's the root directory or the root five system.
And we consider the forward slash the top level and all Derek choose under fire system and leanness
come under the forward slash.
You also have the slash shoot.
We consider this.
We consider it a special dehorned day victory for the user route.
We have the slash def.
This Takechi has devices Fi's details about the system devices.
For instance, physical devices and other information about devices.
We have also the slash horn we consider to slash home to homogenic to for every user and assistant or
person or Derek Disneyfied unsigned for every user are saved.
And out under the slash world, as we can see here, we have Tom and Mary, the steel users under Tom.
We have a joke to documents and we have also here.
It takes five with context.
The same thing here for Mary.
We have a tale of two pictures and then we have photo, that being Bingy here.
We have the slash temper, as we can see here, and this diagram, this static to you basically is like
a stretch.
However, it stores temporary fires whenever we reboot the system.
Everything is going to be deleted from the slash temp.
We have the slash.
You see this extra A has many dedicated his file.
Shield scripts and programs with their configuration files that execute a Linux distribution, for instance,
bes b best WD Ruber towards security if stab and crosstab tab sign.
Also here we have the slash boot Desertec.
She has boot files and information about conflagration for boot files and details about Kirner of the
Linux disputing.
For instance, some of these searches on fires and under the slash put out a grip and grip, too.
You can see we have to grieve, too.
And we have to grieve.
Also, we have a text file here to grip that safe, which is the confirmation fight.
We also has has he will veto.
As you can see here in this diagram, we have this slash var.
This dad actually has some date information that most of the time changes and updates.
They are common directories and a slash bar.
For instance, log male Spaull and opt for those all those directories.
The most important directory inside the slash bar.
It's the log file.
Just slash bar.
Slash log stores.
This.
OK.
This dedicated a slash look stores unsafe system log files and activities for files systems.
For instance.
Booth that log messages yump that log Mayr log unsign.
We have also here this clash broke, this story contains information about current Lennix Gerner, for
instance, uptime devices, memory information swaps, partitions, C.P.U, an unformed information,
unsoiled.
And there's also other Derek cheese.
And we can notice here in this program, there are as many directors under this under those directives
I just mentioned about some of those.
And we can save directors and files under these directors.
That's conclude our session.
Thank you.
And see you in the next lesson.
