Recently attended a friend's wedding. Far away, without taking the computer. So it hasn't been updated. Very ashamed, starting from today to formally update the study content.

First, VIM

Vim is the upgrade version of VI, the biggest difference is that when editing a text, vi will not display color, VIM will show the color.

Yum install-y vim-enhanced installation vim
