vim相关知识积累，持续更新中。
常用操作一般模式切换到命令行:!command 暂时离开执行command的显示结果set nu显示行号块选择
按下v或者V或者[Ctrl]-v时，这个时候光标经过的地方会开始反白，y键可复制，d键可删除
替换文本中指定字符
在命令模式下
:%s/需要被替换的字符/新的字符/g
% 为正则表达式，表示文本结束，s 为 substitute 首字符，g 表示全局
环境设置与记录
vim的环境设置参数有很多，如果你想要知道目前的设置值，可以再一般模式时输入set all来查阅，不过设置选项实在太多了，在这里列出一些平时比较常用的一些简单的设置值
也可以通过配置文件来直观规定我们习惯的vim操作环境。整个vim的设置值一般是放置在/etc/vimrc这个文件中，不过，不建议直接修改它。建议修改文件~/.vimrc这个文件（默认不存在，，请自行手动创建），将希望的设置值列入。
set hlsearch”高亮度反白set backspace=2″课随时用退格键删除set autoindent”自动缩排set ruler”课显示最后一行的状态set showmode”左下角那一行的状态set nu”行号set bg=dark”显示不同的底色色调syntax on”语法高亮
一份不错的 vim 环境配置文件
