Linux Command Line for Beginners: Easy Way Out

The Terminal

How to start your terminal is the first question that should come into your mind.

After searching TERMINAL, you will get to see an icon that is has a title called TERMINAL. This is what you are searching for a very long time. Now that you have got it, you have to click TERMINAL and it will run.

So, now that you are running this, you always need to keep in mind that there is an issue regarding the lowercase and capital letters. There are differences between the lowercase and the block letters when you are typing any sort of commands. So, before typing command, check it well that if you are typing properly or not.

Is
