vi is a very powerful text editor where most of the Linux distributions provide. vim is an improved version of the vi editor with more features. Most of the intersecting features comply with vim. In this tutorial, we will learn how to use
vi from start.
We will start by opening a text file by providing the name of the file. In this example, we will open the file named

p command like below.
We can delete the current line with the
dd command. As stated this will only delete the current single line. If we want to delete from the current line to the down we can provide the line numbers between d’s. In this example, we will delete 5 lines from the current line.

Save and Quit
We can also make some work quicker. We want to save file and then quit. This can be down with a single command
Quit without Saving
If we made some changes but do not want to save them and preserve the original file we can use
