Linux - Manual pages

now here we I'm going to talk about a

very important concept called as some

man pitches now for example you are

using some of the commands and you do

not know how to use the command

completely you do not know what the

parameters are the man comes function or

this man pages will be helpful for you

them so as we have discussed in earlier

into the data structures or the

directory structures we have seen we

have multiple directories into that we

have the Lib directory which contains

all the help files so if you remember

those help files we are going to use it

for getting access for the commands help

now if I have addict particular command

to check the parameters or to check for

what the commands purposes we can go and

use the help commands so let us check

how this help or the manual pages can be

used as is commands if you are using you

can go for getting the number of options

of this particular commands like we have

seen LS LS is for list and a space - a

means for hidden files LS space hyphen i

I can use for getting the inode numbers

and a space - L I can use for thee

getting details of the file so all these

particular parameters which we have

which shows me completely different

output of the same files or or the same

list the same way there are many

particular commands which have different

parameters to give you different outputs

so those particular options and demanded

lis options which you have we can check

by using this manual pages and also this

is a help file what we have discussed

there's a help file which is also called

as a bank pages man pages is a short

form of your manual pages so if there is

a command you want to check for you are

not sure how to use it or then man pages

will be helpful for you in the sky way

so how you will be using or how you will

be getting access to the man pages you

do not have to move into the library

just on the prompt you just need to

define man and apart from that just we

find the name of the command you want to

get the spread and get the parameters

off so let us see how we can check the

commands a parameter is by using this

man come on so we can check for manual

pages by giving man command from

anywhere so man

and then we can add the manual page

command which I'm looking for like you

know if I want to search for cat command

and what the parameters are cat command

has so we can check for it inside the

different parameters we have it will

show you why we use the cat command and

you know what's the uses of it if you

want to quit out of here plus a rescue

okay and then if suppose I want to look

for LS commands so you can also check

for LS command it's for listing the

directory content it will show you

complete details of your complete MLS

come on alright so you can check for all

the parameters you have like why we use

those particular parameters the complete

descriptions are given over here into

this thang so these are the lines of you

know come on we have so also we can

check for you know some related commands

are also given like if you have this can

also check for the info commands so the

like your man pages you also have the

info so info will give you the same you

know information about the complete

command that is your LS command it's

complete description about it then it

will start with the list of your

parameters into it so either you can go

for you know complete call you know

advantage of using your commands by

using the list so it will show you all

the particular you know the parameters

as well as how you will be able to use

those particular commands and everything

it is going to show you in details so

that is the called as a cold utility

information that we generally get into

the info then also we have P info you

can give for looking out the number of

commands you generally have and which

command can be used for what purpose you

can select any of the command and you

can get access to it right so these are

the number of commands and really we

have we can use into the Linux operating

system we can get the information about

it by just be info right so this is our

the help file generally we get into the

Linux operating system we have talked

about info we have talked about here

being full and your man pages or if

suppose you do not want to use any of

the command you can also press f1 so f1

will help you to get the help so I can

check I have pressed the f1 and it was

directly providing mediator nominal

helps so it will show me how to execute

a particular command it will show you

how I can open the terminal step-by-step

what exactly you can do so for each and

every you know help you require you can

also go for your f1 health which will be

a graphical help provided to you so

again you can also use help command so

it will show you all the particulars

commands and live each we can use at

this particular prompt so this are the

you know commands we have seen that is P

info in for man and then we have seen

how we can get the help command or using

me f1 we can also get the help page

through the browser so f1 will only work

into the graphical console but not into

the command line console so if you are

going into command line console and if I

press f1 it won't do anything it will

just give me another and a beep we can

see now if here I can use the help

here I can use demand pages

okay sorry man and if you know c'mon I

require so I can get all the kind of

help into the command line terminal

moving back to our graphical terminal by

presing all control and f1 so this is

the hub command generally we have into

the Linux operating systems and this

helps you generally you get from the Lib

directory which we have seen into the

directory structure

so here we have completed with your man

failures and getting help from your

Linux operating systems so into next

videos I'm going to show you some a bit

administration of your next operating

system so how we can create and manage

the user account and a group records so

keep watching
