Hello, everyone, and welcome to the lecture keyboard keys used in Linux, now you're probably thinking,
hey, I'm going to the keyboard keys, but I already know these keys.
Great if you know these keys.
Beautiful.
And I would recommend you could go ahead and skip this lecture right away and go to the next one.
But I have created this lecture for those people who are trying to get into it for the very first time.
And I have seen and I have experienced that those people who are trying for the first time have or had
a problem in the past understanding these keys or even pronouncing these keys.
These keys are actually symbols which are primarily on top of the the digit keys.
So I'm going through these keys one by one.
So you understand actually how to access them and how these keys are pronounced.
So let's go to the first key.
First key is escape key.
Escape key is is used when and where you are, especially in a V Ed and you have any key press or in
editing mode, you could escape it and it will get you out of that.
So as it sounds, escape is your escape key as your life saver to get out of any of the previously pressed
keys.
Then we have Tilde, which is the key right below it.
Tilde, is that little curly thing on top or right below that escape key?
Usually when you do CD, Tilde, it's actually taking you to your home directory.
And right below that, Tilde, we have the back tick.
Now don't confuse the back tick with a single code or even comma.
Back tick is kind of like backward and it is like a back door to the single coat.
Then we have the next key is the number one.
And on top of the number one, we have a symbol that is called exclamation point.
Now a lot of people heard of exclamation point great.
Which is kind of like emphasizing something in English and in Linux.
You could also referred this or also many times it is referred to as bank.
The next key is at Zion, and I'm sure a lot of people are familiar with that, if you have an email,
then you will notice that your email has your name in front of it.
And then after that, followed by the add sign and a domain, for example, at Hotmail, Gmail, dot
com or whatever your email account is.
Number three, he has a pound sign on top of it, also referred to as hash tag and Linux.
This key is used and in scripting or in the file or any configuration file to comment out any of the
things that are not going to be used.
And just for information purposes, the next key number four has a dollar sign and scripting language.
That dollar sign is defined as invariable which will cover in the shell scripting module.
The next one is the percent sign number six has the carrot sign.
Also, sometimes it people in a simple language, they call it ASKAP.
But in Linux you whenever you have a carrot, it means anything at the beginning of something.
So if you're doing this minus L and you wanted to grab grep something that starts with something you
could use the carrot sign number seven has an percent and percent or and sign.
So that is also to put something in the background.
If you're running a script, you could use ampersand and it will put the script or your process in the
background.
Then number eight has the asterisk sign.
Also, if you if it is hard to pronounce, you can pronounce Istar so many times.
I also pronounce it star so it doesn't really matter.
You pronounce Star or both are OK then number nine, it has open per parentheses.
Now again, don't confuse open parentheses with that curly braces and bracket, which I will cover right
after.
And the second line.
So keep in mind No.9, the curly thing looks like a half C is referred to as open parentheses.
Number zero has close parentheses.
Then next to it we have the hyphen sine hyphen cyno.
First of all, on top it's an underscore and then the bottom is hyphen, which is also used as an option
or Dasch.
So if you're running a command in Linux, then you have to specify sometimes the options with it.
Every time there's an option that needs to be accessed, you have to specify that Dasch.
So whenever you hear Dasch or a hyphen, they both are referred to as each as the same key interchangeably
plus sine equals sine we all know then we are we have a tab key which actually skips few spaces.
Then there is the most one of the important keys that is curly braces.
So opening the top one is the opening curly braces and the bottom one is opening bracket.
Just like that, the on the right hand side, the top key is closing curly braces and the bottom key
is the closing bracket.
All right.
And Tookey or anarchy.
So this is I'm sure everybody knows and a key.
But sometimes people also referred to this key as carriage return.
Then we have Colin Key and semicolon key.
These two keys are used in scripting language as well.
Or whenever you using the editor, you could specify Colin WQ to save the file, which we'll cover later
on, of course.
Then we have a double code and a single code.
So remember, the single code below is not a comma, so it's a single code.
So double code on top.
The bottom is single code and then the more the key that is mostly going to be used in Linux right here
is called pipe, which is a simple straight line.
It is used to combine a few commands together or take the output from first command and give it to the
second command.
Below it we have backslash.
Now remember, backslash is used in windows.
So whenever you are specifying a path that backslash the path that is given in windows, it is used
with a backslash and in Linux it is used with a forward slash, which I'm going to cover in this line.
The fourth line.
All right.
So key whatever the keys that I'm talking about, that is above numbers that are that can be accessed
by pressing shift key, then we have less than sine and below.
The less less than sine is the comma and the next one is great signed and below the grid as in sign
is period or dot.
Now these less than sine or greater than sine is also referred in Linux as input and output.
So if you are using to greater than sign, it means appending to the file.
But if you use one greater than sine then it will overwrite to our file ever as less than sine will
take the input from the output.
Again, don't confuse it right now.
I just want you to learn how you could access these keys and how you could pronounce this key.
So later in the lecture, I don't want you to be, hey, what is a pipe or what is Tilde or what is
greater than sine?
How can I access that?
So that is why I have this lecture for you.
And then next key is the question mark and and below it is the forward slash.
As I mentioned in the in the line in the rule above it, the backslash is used for windows.
The forward slash is used in Linux.
So you could access the Pat and Windows to the command line, to the backslash.
But in the next you have to use forward slash and deLaski on to cover is the right control key.
You see on the keyboard.
You have to control keys, one on the left side and one on the right side many times in and virtualization
or Oracle virtual box.
If you want to get you get your mouse which is trapped inside the window.
If you want to get out of that and release your mouse, you have to use it.
There's a right control key also in Linux.
When we are using certain commands and you do right control key, it will do a different function than
than pressing the left controls.
All right, guys, so I hope now you understand each one of these keys and how to access them and how
to pronounce these keys.
Now, maybe I have pronounced a couple of them differently, or maybe it's pronounced a different way,
depending on which country you are living.
But that is perfectly fine as long as you know where and how to access each one of these keys.
But in Linux world, most of the time that I have experienced these keys are accessed or pronounced
the way I have explained in this lecture.
Anyway, I hope this lecture served its purpose.
And if you have any question, please do send me a message about any of these keys.
Or if you don't understand the functionality of any of these keys, good luck.
