Let's compare the difference between the VI and VIM open
Let's open the/etc/passwd/with VI and look at it.

·
Take a look at the vim/etc/passwd/again.

We can see VI open/etc/passwd/is no color, and with vim open, is color, this is the biggest difference between the VI and VIM
·
Do not modify the contents of the/etc/passwd/inside, this is the system files, after reading: Q Do not save the exit can
·
Vim is divided into 3 modes, general, edit, default mode of the 3 modes
General mode: We can do things like DD delete a whole line of content

Vim color display and move cursor
We already know, the vim configuration file, there will be color display, but the same configuration file in different directories will not display color
For example: We move the/etc/passwd/to the/tmp/, and then vim he will not show the color

·
Whether the vim color shows many aspects, such as the directory, suffix, etc.
·
VIM has its own configuration file, in/ETC/VIMRC
Users can configure their own vim:

·
Move cursor: H left, l or space right, J, K
We can also use the number plus the key to move the cursor, meaning to move a few letters in this direction.
