Kumar Kalyan Hi everyone, I am back with my new article.
The command line is a text interface for your computer.
It's a program that takes in commands, which it passes on to the computer's operating system to run and as a developer you must about these commands. Here, I will discuss about the commands we use in windows. Now there are a lot
of commands so I am going to discuss about the most used and this one is the first article of
this series. So, without wasting your time let's begin :D
md or mkdir
md or mkdir stands for make directory (also known as a folder)
so, this command will create a folder directly from the command line

└───C
C:\A>cd B
C:\A\B>
cd/
To jump directly to the root folder of our command we use this command
C:\A\D>cd /
C:\>
