Linux Directory Management

now in this video we are going to see

how we are going to manage trajectories

so into our earlier videos we have

discussed all about the first so let us

begin with managing a directory now now

very first command we have that is

called as a CD CD command is changed in

our directory now if I want to change

your directory from one directory to

into the other directory I can use a CD

command either by defining a the

complete path of the directory where it

is located or just by immediate

directory we can move in by using the CD

command CD command itself can also be

used if I directly want to move into my

home directory now for example I'm using

or getting login the user 1 then user 1

if they wants directly move into its

home directory so that it can create a

directory or a false and create or save

any kind of content he can directly use

just CD command without following any

particular directory name or directory

path

same way if I want to create directory

of my own I can use the command called

as mkdir mkdir following with the

directory name so automatically it will

create a directory into the present

location same way if I want to create a

directory into a different path or

different location

I can go for mkdir space and the

location where you want to create your

directory and the third option we have

that is LS space hyphen and a so

basically in a space - L a will show you

all the hidden directories and the files

which you have located in to the present

directory now if I want to check how

many files are created and what are the

hidden files or directories we have into

our present directory we can see over

here by using LS space hyphen L a got it

the next week we are going to see is

like how we are going to use this

particular LS space - a for looking on

the hidden files which by default get

created when you create a directory and

you will also see all the details of

this particular directories as well like

you can see the time of creation of this

directory you might have the permissions

for this particular directories and the

owner name and group name every

what we generally we have into our

existing file or directory so basically

this dot and double dot by default get

created when you create a directory into

the Linux operating system what this dot

and double dot means dot here contains

the present directory

means if I have created a directory

named ABC so this is the directory where

I am so this is my current directory now

for example this ABC is created into a

lie parent directory which is /mnt so

this M&P is my parent directory where

this is my immediate parent or immediate

folder where I have located so this

particular directory is my parent

directory so it will show me the details

and deformations of my paring directly

by using double dot means present

directory and near the dot for my

immediate working directory so these are

the two generally hidden folders we

generally get into the directory when we

create so let us see how we generally

use it directly how we create a

directory and how we can find this

directories and their details so here I

am on desktop I can give the command

list and you can see there is no

directory created over here now if I

want to create a directory I can give

the command mkdir and in to mkdir i can

also define the name of the directory

which i want to create so i want to

create a directory with name dir one

that is directory one so you can see now

to the crease will create early desktop

along with that we can also choose see

this rectory into my terminal as well no

directory has been created now if I want

to create multiple directly at a time

like if I want to create directory to

directory three directory for I can add

it and you can see the directories are

created same way if I want to create a

directory or a file with space within

two words now for example I have a two

word of directory name iymp data but I

want a space in between so how I will be

doing is I need to define I am P and

backslash and one space between the

other word so other word is data so it

will create a directory with name

I am P space data

if you do not give this backslash and if

you give more than one space it will

treat both the word as two different

directory that's the reason just

understand it you need to give a

backslash and space after the first word

right so here we have created a

directory with name I MP data this is

how generally we created directory see

if I want to copy a directory I'll be

giving the copy command using CP space

hyphen r CP space hyphen r but before

the directory generally if I copy this

or if I try copying it by using the same

CP command which we have done earlier so

it will prompt me an error it's showing

you omitting directory so if I want to

copy a directory on same place or a

different place the concepts are

completely different as we have used

into the copying of file so I can check

it is being copied it is so Mullane

location with the different name called

as folder one same way we can rename a

particular trajectory for example I want

to rename my mp data and I want to paste

it same way well even renewing it I can

define in such a way and I want to

rename it basic one so I can check it

has been renamed Lee when we can check

it graphically right so this is how it's

a really big create of our directories

as well as we have seen how we can copy

directory and how we can move in

directory same way if I want to delete a

directory I'll be giving Lee come on RM

space - or because if I give command RM

and the directory name again it will

prompt manner that this is a directory

so for deleting a directory I'll be

giving the come on RM space life or not

directory one so you can find directory

one is delete it from here as well as we

cannot find it in the terminal as well

same way if I want to delete multiple

directories I can give the same command

RM space hyphen r dir to and dir

it will be deleted got it now he'll put

up we are not getting any confirmation

on our prompt but if suppose you have

anything into a directory for example

I'm moving into the basic one and I'm

going to create some touch files here so

I'm adding three different files which

are empty files Word Excel PowerPoint

and now I am trying to delete this

directory basic one

I'll give the same command it has been

deleted right so you can delete

particularly by using this RM commands

directly so if there if you have

particular file into the retreat will go

for recursive data and will delete

everything into the directory now if

suppose a same way if we have filled

some file along with the content for

example I am moving into the dir to ok

directory for is there 32 we have

already deleted I'm going to create a

firm cat while one add something into

the file demo file for RM come on I'm

going to hit enter

safety file move out of the file I can

on desktop LS come on again we are on

next open we are able to see the FDR for

again if I'm trying to delete this at

his men delete it so it doesn't matter

which kind of directory in which kind of

content you have recursive means it will

delete everything whatever you have

added into the directory so this is how

we have seen how we can manage the

directories and also we can see like if

suppose I am moving the directory and

what the content generally we do have so

into folder one if I give the command LS

so there is nothing as of now but as

discussed currently VTO that if I give

command at a space - L or LS space - al

that is list all

in details so you can see there are two

dots now this one and this one this dot

is the current directory which is your

folder 1 and this 2 dot contains the

permissions of your parent directory the

parent directory which you have that is

your desktop so this is the formation

you can check for the formation of your

parent directory it is

read/write/execute read and execute read

and execute here and this contains read

write execute read write execute and

read write execute this is to check the

next hop formation whether we have the

same formation on to it for that I'll

just step back from my folder and the

parent folder that is desktop let us

check about the next herb directory ll

or I'll just define a little come on so

you can check for next op they have the

same command which we have found over

here that means this double dot is

nothing but it is showing you this is my

parent directory which is having this

particular formation it is created by

this particular user along with this

memory location number right and while

the folder we have that is containing 2

and this has the permission what our

folder has so this is our current

directory permission and this is the

permission of your parent directory so

always your current directory will show

who is its parent so that it can this

the complete part of the file or

directly where it is stored so this is

what we have seen about managing the

directory in the next video we are going

to explore more Linux operating systems
