Linux Standard Linux Streams

so here in this video we are going to

see altogether different kind of files

which are inbuilt into the Linux

operating systems

so this basically all the files will be

used while we are creating a strip or we

are coding or creating a program so

basic we have three type of this framing

files very first called as stdm

so this is a standard file where it

takes the input so once we define the

input that is called as stdin so if I

want to define anything inside I'll be

using this STD n where the description

of this particular file will be 0

completely into the Linux operating

system the next we have that is called

as STD out so this STD out is forgiving

the output so whenever we give any

particular output by using any

particular program this particular STD

out file is called by your program so

that we can get the output and the

descriptor for this particular file is

one same way we also have stderr it's

for the errors now if we have run any

particular program and there is an error

of that program or we have defined some

input into a program you know for

example if someone has asked for our

name and we have defined some number in

two it means we are giving a wrong type

of data to this particular variable so

that time it will prompt an error this

error will be provided or called by the

macro called as stderr now stderr has a

descriptor value of 2 so this file is

called while you are having the error so

this particular files all be used into

the programming's which we are going to

see when we are going to start with your

shell scripting
