Linux - Types of linux shells

so into our previous video we have

already seen about this shell now each

and every operating system either your

Linux or Windows operating system has a

shell but unlike your other operating

system your Linux has multiple type of

your shells now why this types are

created so that we can understand and we

can run in different languages or

different programs into different shells

so they basically were divided

previously into the Linux so earlier we

had a different type of shell called as

s ships SH is a type of shell which is

called as a secured shell now basically

when we started using a Linux operating

system or the UNIX operating system we

used to have the secure shell means by

default this shell is got logged in

through the user called as root that is

your super user super user get login he

can do everything securely into your

operating system so they used to use

this asset shell called as a secure

shell but that time we have only one

login which is a default login for the

user root so if I want to create a new

user I can create the users into it I

can manage the users I can get logged

into the users not by the console not by

the terminal but I can switch the users

the next type of shell we have that is

your K shell called as console

so this shell we have created so that we

can run multiple type of programming's

like your programming switch we have in

the pole and a different programming

languages so we have to use console

suppose that we brought a new kind of

programming languages called as a C

language so for C language we doing

Hardy kernel support that is key K shell

support for running weeks key

programming's so your C shell is been

introduced so that we can run all the

programs created into the or by using

the C shell programming or C programming

so next we have that is called as a

restricted shell now this shells allows

you to get terminal login by different

users which you create we can create

different programs according to our

different users which we have created

and we can also restrict the other

particular users to use our programs so

this were provided into the restricted

shell suppose that we have

multiple shells even in few go for a

UNIX flower you will find many more

shells like your TSS there are many

things many shells but right now these

are the shells which we have into most

of the distributors of your Linux

operating system now the large shell we

have called as a bash shell or does

bourne-again shell which is the same

shell which we have called as as such

kind of secure shell but along with that

we have included all the shell into it

so that if I'm using this shell called

as bash I can run any of the programming

language any of the program created into

any of the languages along with that all

the particular logins users will be

secured and we do not have to provide

any restrictions by default it will be

restricted by this particular shell

itself so now if you get login by user

by default you will be into the bash

shell if you want to run any particular

program into a particular shell you need

to mention that in which shell you want

to run the program even though if you do

not mention this particular program will

be run with the appropriate shell so

this is your bashes so nowadays the

shell which you will find into the all

the Linux operating systems the default

shell is your bash shell so this is

about the shells so let us begin with

how we can use the shell and how we can

program into this particular shells and

modify the entries and create our

different programs for running some

automated tasks so let us bring it into

next video
