Now, in this lecture, we are going to see major characters for command separate.
So as you can see that the semicolon I'll use as a way character that would separate the actual input
and the command that you are trying to inject.
So along with the semi colon, there are several other characters that can be used to inject it or inject
the command, actually.
So developer MiSeq filters to block the semicolon with a character.
So this will simply block over injected data and therefore we need to experiment with other meta characters.
OK, so that is why I'm making this lecture or this video for you.
So first of all, is this symbol and then we are having users.
So first it semicolon.
So semicolon is the most common meta character used to test and inject it flow.
And the Salvadoran, all the commands in sequence separated by the semicolon.
So in most of the cases we will be using semicolon to terminate it or terminate like in case of rescuable
we will be using semicolon or Hassin.
Well, OK then.
We are having this double ampersand, which is also called as an operator.
So this double ampersand would run the command to the right of the meta character.
Only the command to the left execute successfully.
That simply means that suppose.
OK, let me.
So you have to suppose that you are having good condition if OK, so if you are using this and so this
simply means that if this condition is true or if this condition is true, then the control will go
inside the body of it or else if any condition actually.
OK.
So this is the meaning of no ampersand or we can say double ampersand.
OK, so let me.
Is this OK then we are having this or biplane with the correct.
Then we're having this or this thing, this or it also called this double Piramida character is deeply
opposed to the double amputee and it would run the command on the right side, only of the command on
the left side.
So as you can see that this is the thing supposed that if this condition is true and this condition
is false, so but it will run it because this means or means that it should be true or this one.
OK, so then it will run.
Then we are having and that's what you can see, plenty of it.
So using this grouping metacarpal, you can combine the output of the multiple commands and stored it
inside the fight.
OK, so then we are having this uncoated character.
So this is UTU for the cell to interpret and run the commands between the backpack's.
OK, so as you can see that suppose this is the A string, this is the string.
So this will simply it will just so it will just force the cell to interpret and run the commands between
the buttocks.
OK, this is basically a string because it is having Delcourt.
But this this will force to run this particular command.
Then we are having this character, which is also called as the option, which is I think this one is.
Less than OK created an opening so this character would append the output of the command on the left
of the file name on the right of the character.
OK, then we're having this single pipe will will be used to output the command on the left side as
the input to the command side is finding the right side.
So these are all major characters that you should take care of because in the process of injecting data,
you'll be using these very frequently.
So this is all for this lecture.
Guys, thank you.
In this lecture.
