The vim command.

There are many Unix text editors out there, and they all provide specific utilities that can be useful in particular situations. In this article, we are going to teach you the basics of the "vim" text editor, which, in our opinion, is the most versatile and most user-friendly. A great feature of the "vim" command-line tool is that it recognizes different programming languages and syntaxes, enabling it to colorize the different blocks in your code, such as functions, methods, or variables. While not as effected as a language-specific IDE, it can come in handy if you need to make a quick alteration to your code. To edit a file using the "vim" text editor, please type:

vim <file>

The "vim" command is going to open the file immediately.

To enable searching within the file you opened using the "vim" command-line tool, please press the slash (/) button. At the bottom left side of the screen, you are going to notice this "slash" appearing. You can start typing the string, integer, or the specific excerpt of code you need. When you are done, press the "ENTER" button, and "vim" is going to take you to the first match. If there are more matches inside the file, you can press the "n" button, which is going to take you to the next occurrence. To enable the "editor" mode, please press the "i" button, which stands for "insert". You may navigate through the file using the up, down, left, right arrow keys on your keyboard. When you are done performing the changes, please press the "ESC" button on your keyboard, which will disable this mode. To save the changes, please type the ":wq!" combination. If you have made a mistake and you wish to discard the changes, please type ":q!" instead.
