Terminal

Basics we need to know before commands..

Lets take a look at some basic terms which we need to know before moving to actual commands..

In Linux instead of using GUI i.e, Graphical User Interface using Terminal is having more power in your hand. So lets get start with Terminal.

First we understand what is terminal. Terminal we can also call it as command prompt which allows users to enter commands to perform or execute various tasks.

To open a terminal if you are using Ubuntu then you can simply press ctrl+alt+T. You can search for Terminal in your search field (Open your search field by Alt+F2). Or you can open a terminal from Applications -> Accessories -> Terminal.

                                      Refer above process to open a terminal

In terminal you see $ or # symbol in your terminal which clears you what user you are login through. In simple words if there is # then it means you are root user

or. And if there is $ then it means you are normal user.

So in simple words root user is nothing but super user of operating system which is having all credentials or permissions which a normal user don`t have.

                                      Above $ indicates you are normal user

                                Here root and # indicates super user
