Linux - Boolean operators

now here in this video we are going to

see how we can use this boolean

operators already we have discussed

about your different kind of variables

different kind of operators like your

arithmetic & relational operators now

here I'm going to talk about the boolean

operators they are talking about boolean

operators again we have already seen it

uses your or or and operators now again

we can also use exclamation sign for not

now if the course I want to check if any

particular value is false or true I can

give just a not command so which is

called as an inversion now if suppose

there is a true value I want to make it

false so what I'll do I'll make it

exclamation 4 so automatically it will

reverse or invert the value what exactly

you have same way - oh it can be used to

for our values like either it can be a

greater or it can be a smaller means any

way any way any one condition will only

get true both won't get crew at a time

so I can go for Oh so here you can see

your a is the value of your B value is

less than equals is 20 to 20 and same

baby value is greater than equals to 100

so it has the order in between that is

Oh in between so either this can be true

or this can be true so anybody any of

the value can be true or anybody of the

value can be false so any condition can

true get to work

false but here if I give - a - a means

and so if this both the values which I

have added like - dorri your variable a

is less than or 20 and if it is greater

than hundred then only the variable or

the output which you have that will be

true so it cannot accept any one value

if one is false other is true the

complete value will be first the

complete output will be false means you

are not satisfying the condition what we

have added here right so this particular

type of operators we can use where I am

going to compare my two different

variables either by using the or or by

using the and operators so let us check

a small program using the soft raters

into ourselves so here I'm going to use

the boolean operators

so I've used a file with the same break

because the air again will require a

condition so I've just defined a

condition that we have values 1 2 & 3 so

this is the value list I have for B and

0 to 5 we are defining that a the value

between a and B if it is 0 to 5 so it

should break on t2 itself so I've just

defined the boolean operator into that

you can see this if a is equal to 2 and

your B is equal to 0 so the value should

break over there itself so the add the H

value here we can check we have already

defined the a's value so if you go on

calculating unless you are getting the

range between 0 to 2 that is a equal to

1 or equal to 2 so I'll just run it you

can see 0 plus 1 right 0 and this is

your fight so it's just this particular

value either it is equal to 2 and this

again equals to 0 then only it is going

to add D value so it is like we are at a

deep break statement so that it's it's

actually stopped somewhere otherwise

this is an uncontrollable loop we have

but this is how we generally use and and

condition in between your two different

you know conditions which you define so

here there's a men's your and operator

same way we can also use the and

operator into a function where generally

I have used the if as such you can see

this is the end operator I have defined

like the value which I want it should be

between your 10 and 5 so a bad d and

operator so if the operator we have set

is either in between these two values it

will give me a proper output so I can

check here

so I'll just define this is Ange and now

I'm going to add the value is between

not ten to five but it should give me

the value that it is between five to ten

so I've just set a statement that the

value should be between greater than

five the B should be greater than five

Anna should be less than ten so I've

just you find it

you

and here Akina I'm going to define and

the spaces matter here like if you have

provided a wrong space again it will

give you an error so here I have just

defined as values like if a is less than

10 and B is greater than 5 then the

value will be between PI to 10 let us

check

hi if not as such I'm going to run here

the first value I'm going to give that

is 2 and the second value is 4 so it is

showing me the value is not between 5 to

10 so that means it is checking for both

the values right so this should be

greater than 5 and this one should be

greater than less than 5 so this is let

mince 1 should be greater than Y you

another should be less than 10 this is

what exactly we have seen over here like

how we can use this operators and

operators and you're all operators you

can use into some of the functions so

that you can forget the proper output so

into next video I am coming up with the

other operators which we generally use

that is called as your string operators

so let us check into the net sweetie
