In Linux, we can create the file in many ways.
1-3 methods of files creation have already been explained in their respective sections. Please click on them to know more about their syntax.
Here, we will describe the 4th approach, i.e, using editors.

Assume that I have opened a file using vi editor,
We thought file basic operations can be better explained in the form of questions and answers. So, we have framed the same.
These are few which are regularly used on the day to day operations.
