yum install -y vim-enhanced
Install Vim
Use VIM to open passwd after installation is complete
vim /etc/passwd

Move the/etc/passwd to/tmp
vim/tmp/passwd
Found and no color display

Vim color display is related to file's path, file content
Vim/etc/vimrc

And then

vim  /tmp/1.txt

First enter the number and then the arrow key can move the n characters left or right or move n rows up or down

U is redo last operation, up to 50 times

V can move the cursor to select the copied range, X can be cut, and then paste with P
