Vim basics

Vim is one of the most popular text editors in Linux. If you haven’t used yet, these are the basic commands to start.

Opening a file with Vim, inserting text, saving and close

Open a file or directory (from a terminal).
```
vim text.txt
vim .
```
Open a file or directory (inside Vim):
```
:e text.txt
:e .
```
Inside Vim, type i and press Enter to enter “insert mode”. Then you can edit the file.
To save changes, first exit “insert mode” by pressing Escape. Then, type :w (and press Enter) to save changes.
Close Vim typing :q and pressing Enter. You can save changes and close the file at once by typing :wq. If you want to close without saving changes, type :q!.

You can use keyboard arrows or k for up, j for down, h for left and l for right.
You can move the cursor to the top of the file with gg.
To the end of the file with G.
To the beginning of the current line with 0.
To the end of the current line with $.

You can search inside a file typing / and the word (and pressing Enter). Then, you can move to the next ocurrence with n or the previous with N.
You can go to the first ocurrence with ggn or to the last ocurrence with GN.

To select, type v to enter “visual mode” (first press Escape to exit “insert mode” if you were in it) and use arrows or k,j,h,l to select the text.
